Maybe you’ve just forgotten the password, or perhaps the owner/user of the Mac is no longer able to enter it. How to restore access to different models.
Intel
Running processes at different Quality of Service affects their performance differently on Intel and M1 Macs. This explains what happens.
Some apps and other code doesn’t appear to run faster on M1 chips, and some even runs more slowly. Could this be a result of it not using the best acceleration for vectors and matrices?
Passing your Mac on to a new owner has got much easier and more reliable in Monterey – so long as it has got a T2 or M1 series chip.
From the IBM PC XT with its 10 MB hard disk to a SoC which moves data to its SSD at over 7 GB/s. How CPUs interface with peripherals.
Recovering from one regular panic should be straightforward. But what if it’s a boot loop, in which your Mac tries to start up, panics, restarts, in an endless loop? Don’t panic: here are the solutions.
The cores in the M1 and the chip itself are thoroughly Apple designs, and work hand-in-glove with macOS using techniques like out-of-order execution and hints to optimise performance.
On Intel Macs, resetting the SMC was a universal panacea until the T2 came along. What can we do instead with an M1 Mac?
Complete step-by-step instructions for installing a new copy of macOS to an external disk, making it bootable. For Intel and M1 Macs of all flavours.
Why would you want to go to the lengths of erasing your startup disk and installing a macOS upgrade clean? Here’s why, and how to do it.
