The OP asked how to "limit the %CPU used by a process" and this answer does not necessarily do that. It is true that nice will lower the priority of a process, but if nothing else is competing for those CPU cycles, the process will still get them. So, you can heavily nice a process only to find that it is using almost your entire CPU (e.g., "400%" CPU).

Also on MacOS-X the "process" is not the basic object but rather the "Mach Task" and a process can have several tasks... is "nice" still the best way of doing this? | |
| Sep 12, 2020 at 21:26 | comment | added | Tim Campbell | +1 - This is the most correct answer offered because 'nice' is part of the OS and directly ties into the algorithm used by the kernel's scheduler to decide which process gets the next slice of CPU time. It will always work on any Unix or Linux system and is not dependent on any 3rd party add-one. The bonus is that those processes can use more CPU if they aren't competing for CPU time with other processes. | |

on macOS, "Drive" has a different name (OP mentions Safari); should probably show how to reverse the effects (since OP isn't likely familiar with niceness).
