The E cores on the original M1 and M1 Pro chips appear to be managed quite differently, with respect to the performance of background processes at low QoS.
I hope that you enjoyed Saturday’s Mac Riddles, episode 128. Here are my solutions to them. 1: A […]
When you try ejecting a single volume of a bootable volume group on an external disk, other volumes are also ejected even though you chose to keep them mounted.
Apple’s first quad-core chip, the A10 launched 5 years ago, had 2 P and 2 E cores, but could only run one type of core at a time. We’ve come a long way since then.
Here are this weekend’s riddles to entertain you through family time, shopping and recreation. 1: A roll of […]
Confused by this on APFS? So you should be, as it’s complicated by features like snapshots, sparse files, and the file system itself. There’s no single figure.
Understanding how iCloud works, and how files can be downloaded or evicted. Basic tests which are essential preliminaries, and using Cirrus to help.
If your Mac slows to a crawl, don’t just reboot it. Here’s how to discover what the likely cause is, and a structured approach to recovery.
Obtaining estimates for individual P and E core performance of processes run mainly in an ALU and those using floating-point and SIMD gives further insight and confirms the cores haven’t changed from M1 to M1 Pro.
