How to interpret various measurements reported in Activity Monitor, from % CPU to Energy Impact, and how they can be compared across different Macs.
Intel
Ventura can use Rosetta 2 to translate Intel binaries inside an ARM-native virtualised Linux. The impact and importance of this is explained.
It delivers detailed weather forecasts for days in advance, and real-time manipulation of elaborate textured 3D models. But more mundane tasks may not get any quicker.
In Activity Monitor, % CPU isn’t on a scale of 0-100. In M1 Macs, it also makes no distinction between E and P cores, nor does it allow for their changing frequency.
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.
For the great majority of Mac users, M1 series Macs are a big step forward. But some users want the impossible. What can’t M1 Macs do?
How to discover what’s stored in your Mac’s NVRAM, how to reset it in Intel Macs, and how you can changes its variables.
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.
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?
