Last time they did this they managed to pull it off really well. From memory there was the ability to package apps for both architectures so they would run on either machine. And to bridge the gap there was Rosetta which allowed PowerPC binaries to run on intel Mac’s by translating in real-time with a small performance penalty.
How close are arm chips to PowerPC? They’re both risc architectures, right?

- timw4mail 6y agoEh, really well is a matter of opinion. Compared to the earlier transition from 68k to PowerPC, the PowerPC to x86 transition was much more jarring. The 68k emulation was present up until the death of Mac OS 9, so there is some software that could run on the original Mac all the way to the Classic environment in OS X. Rosetta was sufficient for most applications during the transition, but there will always be software that doesn't get re-written. Rosetta was introduced in 10.4, and dropped in 10.7. Only 3 versions.
