Monterey changes the way that Recovery works on M1 Macs, making them more like Intel Macs by using a paired Recovery volume. But that could spell trouble.
M1
Now has three presets to control speed and energy consumption of compression and decompression, together with complete custom control.
How to work out how many threads and which cores are needed to achieve a compression rate up to 1.7 GB/s, and how to estimate power and energy.
AirDrop is quick, convenient and as slow as you’ll get. Ethernet all too often runs at only 1 Gb/s. Here are the fastest solutions involving M1 models.
Using a test of compressing a 1 GB file with AppleArchive, measurements of power used by core clusters show how efficient using the E cores really is.
Using CPU % or Energy values in Activity Monitor appears to show that running code on E cores is less efficient than on P cores. Don’t believe a word of it.
Which of the external disks tested can be used to boot from? Do they work reliably with Secure Boot? Could you boot from an external hard disk?
Armed with just a couple of flashy Thunderbolt NVMe SSDs and his home-made benchmarking app, we discover whether Thunderbolt is any better than USB 3.x.
If apps control the Quality of Service, which sets how macOS allocates them to different processor cores in an M1 chip, how can we have any control?
From the 8 cores of the original M1 chip to the M1 Ultra’s 20, this is how macOS manages threads from apps, services and other code.
