    Does it matter which exact cores or does it suffice how many cores and threads are used?

    Open Activity Monitor and select All Processes and then sort by CPU to show you the process(es) slowing down your Mac or speeding up your fan(s) or causing more heat.

    I use menumeters to monitor my cores and each's usage:

    MenuMeters

    Keep in mind that it sits on the menu bar and I use it to monitor my cores on a constant basis, so it may not be what you're looking for.

    Activity Monitor has a few styles of CPU usage charts that it can display. Between this and the other information it displays, you may not need to install software to get what you are looking for.

    also my guess it that it's threads 1,3,(5,7 if you have them). I've noticed that my i7 (4 threads, 8 virtual threads) uses the odd ones mostly, unless it is hit with a fairly heavy load

    I would assume this means it is using the four real processors first before using a "virtual" core.
