Just wondering if its feasible to rotate usage of the CPU cores to more evenly distribute heat production across the cores and keep max core temperatures down. My MacBookPro is getting fairly toasty during the initial backups of my external drives. QR seems to be favoring Core 1 and Core 2 with their temperatures consistently running in the mid-80C range while Core 3/4 are running in the mid-70C range.

What tasks get assigned to what CPU is completely outside QRecall's control. That's entirely the job of the Darwin kernel and I know of no way to influence it.

Also note that modern, mobile, CPUs often have one core that's more powerful, with auxiliary cores that are more efficient. So intensive tasks vs. light/periodic tasks are going to favor one core, or one type of core, over others.

ok. Thanks. Perhaps I'll point a clip-on fan at the computer.
