@mia Thanks for keeping us updated! Unfortunately it still seems like the issue exists. I installed 3.7.3 around 10:00PM EST last night and memory usage was around 250MB. I just checked my Mac mini M1 now at 10:00AM EST and memory usage is currently at 3.75GB. I will keep it running for another day or so to see if it continues to increase.
Edit #1: Now, at 10:26AM EST after one Time Machine backup cycle, the memory usage has increased to 3.87GB
Edit #2: 11:38AM EST, 3.98GB
Edit #3: 12:40PM EST, 4.10GB
Edit #4: 1:15PM EST, 4.10GB (right before TM cycle)
Edit #5: 1:34PM EST, 4.21GB (right after TM cycle)
Edit #6: 2:45PM EST, 4.32GB
Interestingly the increase was 0.11-0.12GB each time. So over a day 2.88GB, and over a week 20.16GB. Seems like there’s still work to be done!
