Filipe Espósito, 9to5Mac:

When Apple announced the transition from Intel processors to Apple Silicon chips, the company offered a custom Mac mini with the A12Z Bionic chip so that developers could update their macOS apps to support the new ARM platform. The company is now asking developers to return these DTK Mac minis as the M1 Macs were introduced in November last year.

And:

As developers had to pay $500 to get the custom Mac mini with A12Z Bionic chip, Apple will offer a $200 credit for each DTK returned. This credit can be used as a discount to buy a new M1 MacBook Air, MacBook Pro, or Mac mini.

Apple made the Developer Transition Kit available so folks could test and update their Mac apps and be ready when the M1 Macs started shipping. Developers paid $500 for the kit and knew when they signed up that they’d have to return them at some point (returning the DTK was specified in the agreement, no surprise there).

Apple is easing the sting of having to return the “rented” DTK with a $200 “one-time use code” credit towards the purchase of an M1 Mac.

One wrinkle: The $200 expires at the end of May. Presumably, WWDC will be virtual again and will occur in June. And if new Macs are announced at WWDC, this means the $200 will not be usable for those Macs. Some developers are notably unhappy.

All in all, I think Apple could have avoided this PR bruise if they would have clearly laid out the specifics when they released the DTK in the first place. You pay us $500, we’ll give you a $200 credit that expires at the end of May when you return the box. As is, I got the sense that people were expecting Apple to send everyone an M1 Mac. An unfair expectation, true, but Apple could have controlled this from the beginning.
