M3 chips widen the gap between Pro and Max variants. They also change relative performance between P and E cores to make M3 CPUs more versatile.
Apple silicon
Adds bridged networking, VM settings files, prevents inadvertent window closure when a VM is running, and more. Tested with 6 distros.
The M1 cycle took 16 months from basic to Ultra; that shortened to 12 months for the M2. As the first Studio M2 Ultras were being prepared for shipping, the M3 cycle started.
Before Apple had even released its Developer Transition Kit, virtualisation was already one of the 3 pillars of software support on Apple silicon Macs.
Coping with 64-bit code, APFS, the different CPU, the SSV, System Settings, Recovery Mode, and how to get the best from migration and sharing in iCloud.
A strange observation, that the last thread to complete a matrix multiplication task was always much later than others, explored to discover a different strategy used by macOS.
Running a macOS VM on Apple silicon has many advantages: it lets you run older macOS on newer models, is more secure, and convenient, except it can’t work with App Store apps.
If you use macOS VMs on an Apple silicon Mac, folders shared with the host may vanish in 14.2 and later. Here’s why, which are affected, and how to work around the problem.
Comparison between 2 Intel and 2 Apple silicon Macs running vector and matrix functions from Apple’s Accelerate library. Was that new M3 worth the money?
There’s more to getting best performance and energy efficiency on Apple silicon. These vary greatly depending on how apps are coded, as shown here.
