From Startup Manager to Internet Recovery on Intel Macs, and how to engage each of those in an M1 Mac. With comprehensive diagrams.
Intel Macs have 14 different startup modes and variations, each engaged using different key combinations. One True Recovery replaces those with a single action and GUI with help. It’s a big step forward.
Unlike Intel Macs, M1 models always start booting from internal SSD, and can only offer full Recovery from there too. This has benefits, and some drawbacks too.
Improved tests, statistical analysis, and interface, together with a 21 page Help book detailing its range of tests in 5,000 words. Ready to use for real.
Boot disk volume layout is intricate in Big Sur. M1 Macs lose the EFI partition on their internal SSDs and gain two more for APFS. Contents of /System/Volumes has also changed.
Detailed tutorial steps you through getting accurate and reproducible benchmarks for your disks. Also further projects and tests you can try.
Now with proper random write and read tests, sophisticated analysis including group medians and linear regression, and detailing reporting.
