Ableton Forum

Hey y'all,

Just wondering what the status is on Tahoe support for Ableton? I've been getting poor CPU usage and stem support is unusable since upgrading. Wondering if it's worth the time to roll back my Mac OS to Seqoia or if an Albeton update to fix the issues is imminent? Thanks!

Tahoe is not officially supported for stem separation still unfortunately:

I upgraded to Tahoe a couple days ago and running without issue here. I read few posts online where people had upgraded and things were running smoothly, so I felt comfortable giving it a shot.

The issue with Live on Tahoe is about running Stems Separation. The rest should feel smooth as usual.

Got it, thanks.

I had issues with (at least some) M4L devices using absurd amounts of CPU - see viewtopic.php?t=253103

Edit: never mind, see follow up in that thread
