Ableton Forum

sounds stupid and but it did in mine.. sets that use to be at 30-40% CPU now are at 10-15%.. does anybody know why this would be the case? BTW, I reset it on mine because I updated the java security and my macpro had trouble booting up afterwards so I reset the PRAM/NVRAM..

there are lots of strange things going on between apple and live lately...

are you on snow leopard?

What is nvram and how do you reset it ?

@3phase: still on 10.5.8.. i want to upgrade to snow but I use liquid mix alot and it's not compatible with snow.. they freaking take hella long.. i don't even know if ableton is officially ready for snow yet.. actually, i don't even know if they are fully ready for leopard even..

Resetting PRAM and NVRAM
Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.

no

it just works

I knew the pram stuff but thought nvram was some myserious new mac voodoo !

Sounds promising but I'll have to check with the Mac Genius at my local Apple store. I think he's the guy with the orange shirt
Edit: I'm still trying to figure out the hierarchy.

Amazing, the PRAM reset resolved the random high CPU usage issue on my Mac OS X 10.8.4 on MacBook Pro. This was done by Apple Genius when replacing the battery...
