Mac developers are currently in the midst of a major hardware architecture transition. But for some app makers, this is the third time that they have done this.
After years of rumors, Apple announced the transition to first-party Apple Silicon chips in 2020. Then the first Macs with a proprietary M1 processor launched in November and apps started taking advantage of the new speed.
Although the transition is expected to take two years in total, Apple offered a system and devices to make the process easier on both consumers and developers. Existing apps that work with macOS Big Sur can at least in theory simply run as normal on M1.
