Old thread but I wanted to reply since I was having a similar problem with my m1 iMac running Monterey. The CPU load meter never got above 15% on my ancient iMac and was instantly 20% (up to 60) on my m1 iMac. Separate from this, I realized that Live 11's recording buffer was set to 512 samples by default.. dropping it to the minimum (32 samples) got the load meter down to 1%.
The mystery is why latency would correlate with CPU load in the opposite way that it used to, but regardless it solved my problem.
Hi, I have a similar problem. My Mac Studio (max) has CPU spikes, especially when pressing the spacebar (start/stop). Even up to 1000%, while my old 2017 iMac played those sessions nicely. I've also experienced digital clicks in my audio recordings, making them almost unusable.
I'm still troubleshooting, but so far it helps to switch to VST instead of AU.

M1 with 128 samples here and sweet spot confirmed. 8GB RAM - do not know if that affects CPU overall.

FYI this was mentioned by Ableton before, short summary; on M1 processors lower buffersizes are more efficient...
"For larger buffersizes and low load, macOS determines that it can use the M1's efficiency cores to do the audio calculation, and it only switches to performance cores when the load hits certain thresholds. With lower buffer sizes, macOS uses performance core more predictably. We're in contact with Apple about this issue, but it's unclear when / if we can improve this or if this requires a fix by Apple."

Hey everyone, I've recently gone from a PC laptop to an M1 Mac mini (2020) 16gb ram, I'm also encountering the issue of my CPU load being high at all times (on my basic template it sits on average at 25% or so, I tried changing the buffer size to be lower which didn't help, and tried remaking my older racks again to see if that helps. No joy!
It sometimes peaks really high even when just playing on my hardware synths - I've got basically no heavy VSTs or effects loaded too.
Has anyone has any other solutions or heard anything fe Ableton on this?
Thanks

If you're on L11, do cmd+i on Live's app icon, it'll open a window, here make sure the Rosetta option is switched off.
If you're in L10... this version isn't m1 compatible so it'll run in Rosetta no matter what.

On Apple Silicon (M1/M2) make sure that the buffersize is set to 128 samples as this is the optimal setting.

I did try this as well but it remained the same really! Will try the solution suggested above later but seems a bit random!

Which version of Live are you using? I have same config Mac mini M1 and no utilisation issues at all...

I'm using Live 11 (11.2.7) - the only thing I'm wondering is if it's an issue with my default template which was carried over from my PC version, could that be the issue? I don't want to really recreate this whole thing again with all the routings and everything but can if that could be an issue.

"Open using Rosetta" is off anyway here
