Major UI Lag in Logic Pro 9.1.7 on OS 10.8?

Hi,


I've just completed my first session in Logic 9.1.7 on a Mac Pro Quad Xeon 2.6 after upgrading to Mountain Lion 10.8. I got through it, but experienced the following new bug (as compared to running in Lion 10.7.4:


I noticed that if Logic is currently playing when I double click on a plugin in the channel strip, and then try to stop the playback (keyboard or by clicking the transport in the arrange window), I will get from a 5-45 second lag before the app responds and actually stops. No mouse or keyboard commands seem to work while it's hanging up.


Workaround: Only open plugin windows when playback is stopped, and then playing and stopping works fine (although maybe a little more laggy than in the former OS still).


Is anyone else experiencing this or have any better workaround ideas?

Mac Pro, Mac OS X (10.7), Quad 2.66GHz, 16GB, 18TB HD / RAID

Are the people with a brand new Mac of 2012 immuned from this lagginess?

Do u think apple is forcing us to buy a new Mac?

OS 10.8.3 seem eons to come, if ever.


Nope. Bought a brand new mac in October of 2012. Same problems.


Off topic so I apologize in advance but the Mac Pro is going away in my opinion. The machine hasn't changed or been updated for 3 years. No thunderbolt.

What you mean is logic will lag differently in different Mac with same configuration?


No.. What I am saying is that two people with identical Macs can either have this issue or not. It is not directly related to the hardware.


Example,


I have Mac which is identical to the one, one of my clients owns. He had the lag issue and i didn't. So, as a test... I cloned my hard drive and put that cloned image onto his hard drive and the lag issue vanished for him.


Thus proving, as best one can, it is not directly related to specific hardware.

AofS, I have 3 computers, two of which are 2008/2009 MBPs, but my Mac Pro (a mid 2012 model), which has had the lag issue from day one, had everything installed with the upmost care. I have only installed a very small handfull of 3rd party effects, and went through intensive testing with tech staff to prove that it was none of these. Just curious what are you basing your guess on?

Fluffy,


What apple4andy is refering to.. is that a few people have found that installing or reinstalling GB 11 after the installation of Logic Pro.. has reduced or completely stopped the lag issue for them... It's only a small number of people that this seems to work for I might add, but it is something that has been confirmed by multiple users as one possible fix.


It didn't work for the one remaining client I have, I might also add, that still has this issue.
