About this Mac mini
The Developer Transition Kit (DTK) was released on June 22, 2020, as the prototype of the Mac computer based on the Apple A12Z Bionic processor to transition the Mac away from Intel to Apple’s ARM64-based Apple silicon. As it was before the release of the M1 Macs, Apple offered it to the developers. It was not treated as an Apple product; it was just used as a tool to enable developers to produce applications. DTK was on loan for registered Apple developers to develop and test applications for Apple’s ARM-based “Apple Silicon” Mac lineup. The device had the model number A2330, which was changed after some time, and the developers were required to return it to Apple.
The DTK features an Apple A12Z Bionic processor with eight processor cores on a single chip, 8 MB of level 2 cache, 16 GB of memory, and a 512 GB SSD. Both the memory and the SSD are onboard. In addition, the device included two USB-C ports, two USB 3.0 (USB-A) ports, an HDMI 2.0 port, Gigabit Ethernet, 802.11ac Wi-Fi, and Bluetooth 5.0.
The case (Space gray) was the same as it would be in the future Mac mini lineup. Although it looks nearly identical to earlier Mac mini models, it is entirely different internally. It has more in common with the Wi-Fi only configurations of the iPad Pro models released in 2020. The DTK was discontinued eight months after it was released, and the developers had to return it to Apple after the development was done. The A12Z processor would then be directly succeeded by the Mac mini computer and its M1 processor.
