I am connecting into an M1 macbook (Sonoma) from a 2019 iMac (Sonoma, 64GB, i9, Radeon 570x 4GB) utilizing Apple Display Sharing.
Particularly when viewing Chrome / Electron based mostly functions, the iMac’s followers begin spinning at full rev, and I discover 100% or extra CPU utilization by the Display sharing app (not globally as proven on the Exercise Monitor graph). I’ve observed that it occurs when there may be mouse or keyboard exercise; as quickly as I swap out of the Display Sharing app on the iMac, the CPU utilization will get right down to regular, even after I hold the Display Sharing window seen, with all of the macbook’s UI updates occurring.
Positive, it is summer time, the 2019 iMac is not a teenager or a graphics dragon, however:
- if I join into the exact same M1 from my 2015 iMac (Mojave), I haven’t got this downside, the followers spin up every now and then, however nothing noticeable;
- it isn’t Sonoma particular, as a result of I haven’t got issues connecting from my M2 macbook (Sonoma, ARD traditional mode, the superior is just too buggy) both (however it may be Intel-Sonoma particular);
- it truly is sure to mouse / keyboard exercise, and it actually is dependent upon the app operating on the M1, Chrome + Electron apps being the worst offenders.
My resolution to date has been to throw cpulimit with a 75% restrict at Display Sharing. It solves the fan noise, however Display Sharing begins stuttering so much with some Electron apps (not all). Then I cease utilizing the mouse or keyboard, and it will get again to operating easily.
Does anybody have any pointers?
