The Apple '''Developer Transition Kit''' ('''DTK''') is an ARM-based Mac released exclusively to registered developers on June 22, 2020. The kit takes the shape of a Mac mini (2018), and was designed to aid developers in the transition from Intel (x86_64) to Apple silicon (arm64) processors as part of the Universal App Quick Start Program. The program costs 500 USD, and supplies a Developer Transition Kit that must be returned after 1 year, or if Apple decides to recall all DTKs. Joining the program requires signing a non-disclosure agreement (NDA) that limits the public demonstration of the DTK, running benchmarks or other performance measurements of the machine, or disassembling it. The DTKs were recalled and asked to be returned by 31 March 2021. Upon return of the DTK, the developer receives a 500 USD credit towards the purchase of other Apple Devices. Originally, it was going to be 200 USD, could only be spent on M1 machines, and would expire 31 May 2021, but these terms were changed after backlash from the developer community.

It shipped with macOS Big Sur Beta 20A5299w, a build made available specifically for the DTK. Like the M1 Macs that came after it, Developer Transition Kit contains a recovery mode accessible by pressing and holding the power button at boot. It also contains a DFU mode it can fall back to or be entered into.

== Variants ==

The Developer Transition Kit has a model ID of [https://everymac.com/ultimate-mac-lookup/?search_keywords=ADP3,2 ADP3,2], and model number of A2330 (EMC 3568), J273a. This is the variant that was seeded to developers. It reports to macOS as "Apple Developer Platform".

In the macOS 11 Big Sur [[IPSW]], there exists references to a variant of the Developer Transition Kit, model ADP3,1 / J273, which has a nearly identical DeviceTree to ADP3,2; the only differences are that it reports as "J273" instead of "Apple Development Platform", and only has 6 GB of RAM, like the iPad Pro 2020, instead of 16 GB, which Developer Transition Kit ADP3,2 has. Whether the external appearance is the same or not is unknown.

In there also exists a model, T485, which is a completely unknown model, with an A12Z processor and a display. Its DeviceTree varies considerably from the iPad Pro (2020) DeviceTree. It is not known what this device looks like.

== Application processor ==

The Developer Transition Kit (2020) makes use of the Apple A12Z Bionic SOC.

The A12Z is a rebranded A12X, using the same [[T8027]] CPU found in the [[iPad Pro (12.9-inch) (3rd generation)|2018 iPad Pro]], but including an improved 8-core graphics processor (7-core in A12X).

== Specifications ==

* '''Size:''' 197 mm (7.7 inches) (width) x 197 mm (7.7 inches) (length) x 36 mm (1.4 inches) (depth)
* '''Color:''' Space Grey
* '''Weight:''' 1.16 kg (2.54 lb)
* '''Storage:''' 512 GB, connected using Apple Fabric
* '''RAM:''' 16 GB (for ADP3,2 released to developers)
* '''Wireless:'''
** '''Wi-Fi:''' Dual-band 802.11a/b/g/n/ac

** 2 x [[USB-A]] ports (5 Gbps)
** 1 x Gigabit Ethernet
** 1 x HDMI 2.0 port
** 1 x AC Power In
[[Category:Devices]]

== Interfacing with Developer Transition Kit ==

Unlike the Mac mini (2018), the Developer Transition Kit only contains [https://developer.apple.com/programs/universal 2 USB-C ports], rather than 4 USB-C ports. Additionally, while both are electrically Thunderbolt 3 compatible, Thunderbolt 3 functionality is disabled on the Developer Transition Kit. The inclusion of only 2 ports may be indicative of bandwidth limitations of the platform, as the Mac mini (M1, 2020) similarly only had 2 ports, albeit at Thunderbolt 3 / USB 4.

The Developer Transition Kit can be interfaced by plugging a cable between the USB-C port on the right and another computer. In iTunes on Windows and Apple Configurator on macOS, it is displayed as an iPhone in DFU mode.

[https://twitter.com/1nsane_dev/status/1296503098546978816?s=21 The Developer Transition Kit also has a functional UART interface from the USB-C port.]

== Hardware behaviors ==

[https://www.hackintosh-forum.de/attachment/151233-dtk-release-notes-pdf/ Developer Transition Kit Release Notes (leaked)]

=== Rosetta 2 compatibility ===

The Developer Transition Kit contains a working version of Rosetta 2, Apple's binary translation layer that allows Intel applications to run as-is on ARM Macs. However, the A12Z, [https://twitter.com/never_released/status/1326516501915066370 unlike A14], doesn't support 4 KiB memory pages, meaning most 3rd party web browsers like [https://support.google.com/chrome/thread/64355557 Chrome] and Firefox stopped working. Both Chrome and Firefox released fixes that allow it to run under Rosetta 2 on the DTK platform. Many [[wikipedia:Electron (software framework) | Electron]] apps, and apps using older versions of the [[wikipedia:Chromium Embedded Framework | Chromium Embedded Framework]] will not run or load pages on the DTK.

=== SOS / DFU mode ===

If the system is unable to boot or load recovery, it will enter SOS mode. This mode is the same as DFU mode, but the light on the Developer Transition kit turns amber and flashes in an SOS pattern (3 quick blinks, followed by 3 long blinks, followed by 3 quick blinks). The Intel Mac mini does not have an Amber LED, so this is unique to the DTK.

According to the DTK Release Notes, recovery cannot reinstall macOS. You need to hook up to another Mac with Apple Configurator 2 to reinstall the OS.

=== Thunderbolt 3 ===

Thunderbolt 3 is apparently built into the DTK, but is not enabled or working for various reasons. Only DisplayPort or HDMI display outputs will work, not Thunderbolt. As a result, the Pro Display XDR can only run at 5K instead of 6K.

External GPUs are not supported on Developer Transition Kit, [https://www.engadget.com/apple-m1-egpu-usb-16gb-224346108.html nor M1 Macs for that matter].

=== System Fan ===

The system fan runs at a constant speed, regardless of processor load.

=== RTC ===

Possibly due to a faulty SMC or other drainage issue, the coin-cell battery only lasts for 6 months. Given that DTK users are not allowed to disassemble the machine, this means that the RTC will permanently stop working after that time.

=== Hypervisor.framework ===

Hypervisor.framework does not work on the DTK. This means that the acceleration needed to run, for example, virtual machines, is missing, so something like Windows 10 would run absolutely terribly.

=== Misc ===

The Apple USB SuperDrive doesn't work for some reason on the USB-A ports and you need a USB-C dongle to use it

Apple Watch unlock does not work

Apple Pay does not work

If the OS is hung, pressing and holding the power button to shut down does not apparently work.

However, the A12Z, [https://twitter.com/never_released/status/1326516501915066370 unlike A14], doesn't support 4 KiB memory pages, meaning most 3rd party web browsers like [https://support.google.com/chrome/thread/64355557 Chrome] and Firefox stopped working. Both Chrome and Firefox released fixes that allow it to run under Rosetta 2 on the DTK platform. Many [[wikipedia:Electron (software framework) | Electron]] apps, and apps using older versions of the [[wikipedia:Chromium Embedded Framework | Chromium Embedded Framework]] will not run or load pages on the DTK.

=== SOS / DFU mode ===

If the system is unable to boot or load recovery, it will enter SOS mode. This mode is the same as DFU mode, but the light on the Developer Transition kit turns amber and flashes in an SOS pattern (3 quick blinks, followed by 3 long blinks, followed by 3 quick blinks). The Intel Mac mini does not have an Amber LED, so this is unique to the DTK.

According to the DTK Release Notes, recovery cannot reinstall macOS. You need to hook up to another Mac with Apple Configurator 2 to reinstall the OS.

=== Thunderbolt 3 ===

Thunderbolt 3 is apparently built into the DTK, but is not enabled or working for various reasons. Only DisplayPort or HDMI display outputs will work, not Thunderbolt. As a result, the Pro Display XDR can only run at 5K instead of 6K.

External GPUs are not supported on Developer Transition Kit, [https://www.engadget.com/apple-m1-egpu-usb-16gb-224346108.html nor M1 Macs for that matter].

=== System Fan ===

The system fan runs at a constant speed, regardless of processor load.

=== RTC ===

Possibly due to a faulty SMC or other drainage issue, the coin-cell battery only lasts for 6 months. Given that DTK users are not allowed to disassemble the machine, this means that the RTC will permanently stop working after that time.

=== Hypervisor.framework ===

Hypervisor.framework does not work on the DTK. This means that the acceleration needed to run, for example, virtual machines, is missing, so something like Windows 10 would run absolutely terribly.

=== Misc ===

The Apple USB SuperDrive doesn't work for some reason on the USB-A ports and you need a USB-C dongle to use it

Apple Watch unlock does not work

Apple Pay does not work

If the OS is hung, pressing and holding the power button to shut down does not apparently work.

Developer Transition Kit (2020)

2021-01-17T09:45:02Z

Dangeredwolf: /* Application processor */

[[Image:DTK2020.png|right|thumb|Developer Transition Kit (2020)]]
[[Image:DTK_Screenshot_WWDC_2020.png|right|thumb|About This Mac screen for Developer Transition Kit (2020), as shown at WWDC 2020.]]

The Apple '''Developer Transition Kit''' is an ARM-based Mac released exclusively to registered developers on June 22, 2020. The kit was designed to aid developers in the transition from Intel (x86_64) to Apple silicon (arm64) processors as part of the Universal App Quick Start Program. The program costs 500 USD, and supplies a Developer Transition Kit that must be returned after 1 year, or if Apple decides to recall all DTKs. The Developer Transition Kit takes form as a modified Mac mini (2018). Joining the program requires signing a non-disclosure agreement (NDA) that limits the public demonstration of the DTK, running benchmarks or other performance measurements of the machine, or disassembling it.

It shipped with macOS Big Sur Beta 20A5299w, a build made available specifically for arm64. Like the M1 Macs that came after it, Developer Transition Kit contains a recovery mode accessible by pressing and holding the power button at boot. It also contains a DFU mode it can fall back to or be entered into.

== Variants ==

The Developer Transition Kit has a model ID of [https://everymac.com/ultimate-mac-lookup/?search_keywords=ADP3,2 ADP3,2], and model number of A2330 (EMC 3568), J273a. This is the variant that was seeded to developers. It reports to macOS as "Apple Developer Platform".

In the macOS 11 Big Sur [[IPSW]], there exists references to a variant of the Developer Transition Kit, model ADP3,1 / J273, which has a nearly identical DeviceTree to ADP3,2; the only differences are that it reports as "J273" instead of "Apple Development Platform", and only has 6 GB of RAM, like the iPad Pro 2020, instead of 16 GB, which Developer Transition Kit ADP3,2 has. Whether the external appearance is the same or not is unknown.

In there also exists a model, T485, which is a completely unknown model, with an A12Z processor and a display. Its DeviceTree varies considerably from the iPad Pro (2020) DeviceTree. It is not known what this device looks like.

== Application processor ==

The Developer Transition Kit (2020) makes use of the Apple A12Z Bionic SOC.

The A12Z is a rebranded A12X as it uses the same [[T8027]] CPU found in the [[iPad Pro (12.9-inch) (3rd generation)|2018 iPad Pro]], with the exception that it has an improved 8-core graphics processor.

== Specifications ==

* '''Size:''' 197 mm (7.7 inches) (width) x 197 mm (7.7 inches) (length) x 36 mm (1.4 inches) (depth)
* '''Color:''' Space Grey
* '''Weight:''' 1.16 kg (2.54 lb)
* '''Storage:''' 512 GB, connected using Apple Fabric
* '''RAM:''' 16 GB (for ADP3,2 released to developers)
* '''Wireless:'''
** '''Wi-Fi:''' Dual-band 802.11a/b/g/n/ac
** '''Bluetooth''' Bluetooth 5.0
* '''Connectors:'''
** 2 x [[USB‑C_Connector|USB-C]], (10 Gbps, DisplayPort-capable)
** 2 x [[USB-A]] ports (5 Gbps)
** 1 x Gigabit Ethernet
** 1 x HDMI 2.0 port
** 1 x AC Power In
[[Category:Devices]]

== Interfacing with Developer Transition Kit ==

Unlike the Mac mini (2018), the Developer Transition Kit only contains [https://developer.apple.com/programs/universal 2 USB-C ports], rather than 4 USB-C ports. Additionally, while both are electrically Thunderbolt 3 compatible, Thunderbolt 3 functionality is disabled on the Developer Transition Kit. The inclusion of only 2 ports may be indicative of bandwidth limitations of the platform, as the Mac mini (M1, 2020) similarly only had 2 ports, albeit at Thunderbolt 3 / USB 4.

The Developer Transition Kit can be interfaced by plugging a cable between the USB-C port on the right and another computer. In iTunes on Windows and Apple Configurator on macOS, it is displayed as an iPhone in DFU mode.

[https://twitter.com/1nsane_dev/status/1296503098546978816?s=21 The Developer Transition Kit also has a functional UART interface from the USB-C port.]

== Interfacing with Developer Transition Kit ==

The major external difference between the Developer Transition Kit and the Mac mini (2018) is that it contains [https://developer.apple.com/programs/universal 2 USB-C ports]. They are electrically Thunderbolt 3 compatible, but this functionality is disabled on the Developer Transition Kit. It can be interfaced by plugging a cable between the USB-C port on the right and another computer. In iTunes on Windows and Apple Configurator on macOS, it is displayed as an iPhone in DFU mode.

[https://twitter.com/1nsane_dev/status/1296503098546978816?s=21 The Developer Transition Kit also has a functional UART interface from the USB-C port.]

== Hardware behaviors ==

[https://www.hackintosh-forum.de/attachment/151233-dtk-release-notes-pdf/ Developer Transition Kit Release Notes (leaked)]

=== Rosetta 2 compatibility ===

The Developer Transition Kit contains a working version of Rosetta 2, Apple's binary translation layer that allows Intel applications to run as-is on ARM Macs. However, the A12Z, [https://twitter.com/never_released/status/1326516501915066370 unlike A14], doesn't support 4 KiB memory pages, meaning most 3rd party web browsers like [https://support.google.com/chrome/thread/64355557 Chrome] and Firefox stopped working. Both Chrome and Firefox released fixes that allow it to run under Rosetta 2 on the DTK platform. Many [[wikipedia:Electron (software framework) | Electron]] apps, and apps using older versions of the [[wikipedia:Chromium Embedded Framework | Chromium Embedded Framework]] will not run or load pages on the DTK.

=== SOS / DFU mode ===

If the system is unable to boot or load recovery, it will enter SOS mode. This mode is the same as DFU mode, but the light on the Developer Transition kit turns amber and flashes in an SOS pattern (3 quick blinks, followed by 3 long blinks, followed by 3 quick blinks).

According to the DTK Release Notes, recovery cannot reinstall macOS. You need to hook up to another Mac with Apple Configurator 2 to reinstall the OS.

=== Thunderbolt 3 ===

Thunderbolt 3 is apparently built into the DTK, but is not enabled or working for various reasons. Only DisplayPort or HDMI display outputs will work, not Thunderbolt. As a result, the Pro Display XDR can only run at 5K instead of 6K.

=== System Fan ===

The system fan runs at a constant speed, regardless of processor load.

=== RTC ===

Possibly due to a faulty SMC or other drainage issue, the coin-cell battery only lasts for 6 months. Given that DTK users are not allowed to disassemble the machine, this means that the RTC will permanently stop working after that time.

=== Hypervisor.framework ===

Hypervisor.framework does not work on the DTK. This means that the acceleration needed to run, for example, virtual machines, is missing, so something like Windows 10 would run absolutely terribly.

=== Misc ===

The Apple USB SuperDrive doesn't work for some reason on the USB-A ports and you need a USB-C dongle to use it

Apple Watch unlock does not work

Apple Pay does not work

If the OS is hung, pressing and holding the power button to shut down does not apparently work.

Developer Transition Kit (2020)

2021-01-17T09:13:51Z

Dangeredwolf: Moved Application Processor up

[[Image:DTK2020.png|right|thumb|Developer Transition Kit (2020)]]
[[Image:DTK_Screenshot_WWDC_2020.png|right|thumb|About This Mac screen for Developer Transition Kit (2020), as shown at WWDC 2020.]]

The Apple '''Developer Transition Kit''' is an ARM-based Mac released exclusively to registered developers on June 22, 2020. The kit was designed to aid developers in the transition from Intel (x86_64) to Apple silicon (arm64) processors as part of the Universal App Quick Start Program. The program costs 500 USD, and supplies a Developer Transition Kit that must be returned after 1 year, or if Apple decides to recall all DTKs. The Developer Transition Kit takes form as a modified Mac mini (2018). Joining the program requires signing a non-disclosure agreement (NDA) that limits the public demonstration of the DTK, running benchmarks or other measurements of the machine, or disassembling it.

It shipped with macOS Big Sur Beta 20A5299w, a build built specifically for arm64. Like the M1 Macs that came after it, Developer Transition Kit contains a recovery mode accessible by pressing and holding the power button at boot. It also contains a DFU mode it can fall back to or be entered into.

== Variants ==

The Developer Transition Kit has a model ID of [https://everymac.com/ultimate-mac-lookup/?search_keywords=ADP3,2 ADP3,2], and model number of A2330 (EMC 3568), J273a. This is the variant that was seeded to developers. It reports to macOS as "Apple Developer Platform".

In the macOS 11 Big Sur [[IPSW]], there exists references to a variant of the Developer Transition Kit, model ADP3,1 / J273, which has a nearly identical DeviceTree to ADP3,2; the only differences are that it reports as "J273" instead of "Apple Development Platform", and only has 6 GB of RAM, like the iPad Pro 2020, instead of 16 GB, which Developer Transition Kit ADP3,2 has. Whether the external appearance is the same or not is unknown.

In there also exists a model, T485, which is a completely unknown model, with an A12Z processor and a display. Its DeviceTree varies considerably from the iPad Pro (2020) DeviceTree. It is not known what this device looks like.

== Application processor ==

The Developer Transition Kit (2020) makes use of the Apple A12Z Bionic SOC.

the A12Z is a rebranded A12X as it uses the same [[T8027]] CPU found in the [[iPad Pro (12.9-inch) (3rd generation)|2018 iPad Pro]], with the exception that it has an improved 8-core graphics processor.

== Specifications ==

* '''Size:''' 197 mm (7.7 inches) (width) x 197 mm (7.7 inches) (length) x 36 mm (1.4 inches) (depth)
* '''Color:''' Space Grey
* '''Weight:''' 1.16 kg (2.54 lb)
* '''Storage:''' 512 GB, connected using Apple Fabric
* '''RAM:''' 16 GB (for ADP3,2 released to developers)
* '''Wireless:'''
** '''Wi-Fi:''' Dual-band 802.11a/b/g/n/ac

== Interfacing with Developer Transition Kit ==

The major external difference between the Developer Transition Kit and the Mac mini (2018) is that it contains [https://developer.apple.com/programs/universal 2 USB-C ports]. They are electrically Thunderbolt 3 compatible, but this functionality is disabled on the Developer Transition Kit.

== Application processor ==

The Developer Transition Kit (2020) makes use of the Apple A12Z Bionic SOC.

the A12Z is a rebranded A12X as it uses the same [[T8027]] CPU found in the [[iPad Pro (12.9-inch) (3rd generation)|2018 iPad Pro]], with the exception that it has an improved 8-core graphics processor.

== Variants ==

The Developer Transition Kit has a model ID of [https://everymac.com/ultimate-mac-lookup/?search_keywords=ADP3,2 ADP3,2], and model number of A2330 (EMC 3568), J273a. This is the variant that was seeded to developers. It reports to macOS as "Apple Developer Platform".

In the macOS 11 Big Sur [[IPSW]], there exists references to a variant of the Developer Transition Kit, model ADP3,1 / J273, which has a nearly identical DeviceTree to ADP3,2; the only differences are that it reports as "J273" instead of "Apple Development Platform", and only has 6 GB of RAM, like the iPad Pro 2020, instead of 16 GB, which Developer Transition Kit ADP3,2 has. Whether the external appearance is the same or not is unknown.

In there also exists a model, T485, which is a completely unknown model, with an A12Z processor and a display. Its DeviceTree varies considerably from the iPad Pro (2020) DeviceTree. It is not known what this device looks like.

The Apple '''Developer Transition Kit''' is an ARM-based Mac released exclusively to registered developers on June 22, 2020. The kit was designed to aid developers in the transition from Intel (x86_64) to Apple silicon (arm64) processors as part of the Universal App Quick Start Program. The program costs 500 USD, and supplies a Developer Transition Kit that must be returned after 1 year, or if Apple decides to recall all DTKs. The Developer Transition Kit takes form as a modified Mac mini (2018).

The major external difference between the Developer Transition Kit and the Mac mini (2018) is that it contains [https://developer.apple.com/programs/universal 2 USB-C ports]. They are electrically Thunderbolt 3 compatible, but this functionality is disabled on the Developer Transition Kit. It shipped with macOS Big Sur Beta 20A5299w, a build built specifically for arm64.

Secure Enclave Processor

2020-08-07T18:19:38Z

Dangeredwolf: Grammar

The '''Secure Enclave''' (not to be confused with the [[Secure Element]]) is part of the [[A7]] and newer chips used for data protection, [[Touch ID]], and [[Face ID]]. The purpose of the Secure Enclave is to handle keys and other info such as biometrics that is sensitive enough to not be handled by the [[Application Processor|AP]]. It is isolated with a hardware filter so the AP cannot access it. It shares RAM with the AP, but its portion of the RAM (known as TZ0) is encrypted. The secure enclave itself is a flashable 4MB AKF processor core called the secure enclave processor (SEP) as documented in [http://appft.uspto.gov/netacgi/nph-Parser?Sect1=PTO1&Sect2=HITOFF&d=PG01&p=1&u=%2Fnetahtml%2FPTO%2Fsrchnum.html&r=1&f=G&l=50&s1=%2220130308838%22.PGNR.&OS=DN/20130308838&RS=DN/20130308838 Apple Patent Application 20130308838]. The technology used is similar to [http://www.arm.com/products/processors/technologies/trustzone/index.php ARM's TrustZone/SecurCore] but contains proprietary code for Apple KF cores in general and SEP specifically. It is also responsible for generating the UID key on A9 or newer chips that protects user data at rest.

The SEP is located in the devicetree under IODeviceTree:/arm-io/sep and manged by the AppleSEPManager driver as seen [http://winocm.com/images/ioregdump.txt here]

==SEP OS==

The SEP has its own OS called SEP OS which is based on Darbat/L4[https://www.blackhat.com/docs/us-16/materials/us-16-Mandt-Demystifying-The-Secure-Enclave-Processor.pdf][https://ts.data61.csiro.au/publications/papers/Lee_Gray_06.pdf] and there exists a tool called [[seputil]] which is used to communicate with it.

[[File:Apple TV 4K.png|thumb|131px|Apple TV 4K]]
The Apple TV 4K starts at $179 for 32GB of storage, and $199 for 64GB. Its firmware identifier is AppleTV6,2. It is capable of playing 4K content.

The Apple TV 4K was announced on 12th September 2017 and released on 22nd September 2017.

== Application processor ==
The Apple TV 4K makes use of the [[T8011|Apple A10X]] processor.

== Debug Port ==

[[File:AppleTV4K_Debug_Ethernet.jpg|thumb|right]]

Hidden behind a small trapdoor in the back of the Ethernet port is a debug port that includes USB access.

Without a custom cable the easiest method of access to the port is to solder directly onto the pins. Care should be taken with the test points that are near the port as they also serve as the top of the via that connects the debug port to the rest of the Apple TV. USB access is disabled in tvOS due to us not knowing how to instruct the AppleTV that a device is currently connected, but this limitation does not exist in DFU or Recovery. While the Reset pin pulls force dfu high, secureROM requires that it detects a USB connection. At this time it does not allow entry into DFU.
