Many processors like the ARM64 have instructions to perform fused multiply-add operations. Do they deliver reduced error and better performance?

We commonly suffer failures of the psychology of Mac performance, when system background tasks overwhelm the processor and bring the interface to a grinding halt
By segregating macOS background tasks on Efficiency cores, M1 Macs can run user apps unfettered on their Performance cores. And that feels really fast.
How the M1’s asymmetric cores can run background tasks more efficiently, or deliver high performance, according to Quality of Service.
How can it take over 5 hours to back up 79 GB of files to a network share? That’s an average transfer rate of 4 MB/s, probably slower than your Internet connection.
Using EtreCheckPro to identify periods of high CPU, then exploring those in the log using Ulbow. A short and simple workthrough.
With Intel Macs, we’ve often bought as little RAM and storage as is essential, and enhanced or upgraded using third-party products. Does this work with Apple Silicon models?
Progress benchmarking performance of internal SSDs in M1 Macs: tests of 400 files totalling over 130 GB written and read in less than 50 seconds. And results.
Fast compact external SSDs are prone to thermal throttling. This is demonstrated during tests writing 96 files, when transfer rates fell from 2 GB/s to around 700 MB/s.
Although little more expensive than good Thunderbolt 3 cables, what are the differences in Thunderbolt 4? When do you need a new TB4 cable?
