Each additional Safari window increases WindowServer’s memory use by 1.7 MB on an Intel Mac, but 50 MB on an M1 Mac – thirty times more.
How to use an M1 Mac’s Recovery system to boot in Safe mode, boot from another disk, and use its other important features. With a map.
When running some tasks confined to E cores, the original M1 chip from 2020 completes them significantly quicker than an on an M1 Pro. Here’s the detail.
Users and other processes have very limited control over which threads are run on which type of core. As Apple Silicon develops, this is an area set for change.
Fed up with your M1 MBP always starting up, or waking from sleep, when you open its lid? How might you change that behaviour?
