Apple announced plans to transition their Mac lineup to in-house ARM-based processors earlier this year. This decision came as a result of Apple's dependence on Intel for new processors each year and their recent underwhelming improvements. The upcoming 12 core chip is expected to be manufactured on TSMC's 5 nm node which should deliver significant power savings and performance. Apple has been working to optimize macOS and first party applications for the new processors along with sending out developer transition kits to hopefully ensure major software is supported at launch. The processor is rumored to debut in an upcoming 13-inch MacBook Pro or a new MacBook Air and should launch at a dedicated event in November according to a recent report by Bloomberg.
