Apple has announced a major expansion of its self-repair program, as the company will now allow iPhone 15 and M2-powered Mac users to fix their own devices. This comes after the tech company opened up the program to include iPhone 14 models and M2-powered laptops earlier this year. The devices added to the DIY repair roster include the entire iPhone 15 lineup, the Mac Pro, Mac Studio, the 16-inch MacBook Pro and the 15-inch MacBook Air, among others. There's also a brand-new diagnostic tool to help users to get to the bottom of things. Apple already offered a System Configuration tool that came up when the device was in Diagnostics mode, but this goes several steps further.
