In less than 5 years, Macs have gone from unsecured firmware and booting to a fully secure process to deliver, install and run firmware which can’t be exploited.
Apple silicon
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.
Just how fast is a Mac Studio with an M1 Ultra? It all depends on the factors discussed here, with details of M1 series CPU performance.
With no possibility of memory expansion, and no upgrading of internal storage, you need to specify your M1 Mac correctly. Here’s how.
How can you tell how much memory is being used by the GPU when both CPU and GPU use Unified Memory? Does it matter anyway?
Can you get Time Machine to back up faster by turning I/O throttling off? If so, it this something to do only for large backups, or can it be set as the default? Does it also affect other background processes?
Current CPU % given in Activity Monitor can be misleading and has limited value for M1 models. Here’s how to improve it.
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.
When running some tasks confined to E cores, the original M1 chip from 2020 completes them significantly quicker than an on an M1 Pro. Here’s the detail.
