Major UI Lag in Logic Pro 9.1.7 on OS 10.8?

Thanks for this, Nick. I'm going to try it myself today! Thing is, Apple tech staff seem to have isolated it down to a Core Audio problem introduced in Lion and made greater in Mountain Lion. Does that make sense with your solution? Admittedly I do not really get the technical stuff at all...

This is the issue: http://mactips.dwhoard.com/mactips/other-applications/spaces-auto-switching

Basicily explaining what I said but better and the reasons why!

Also this is probably rhe real reason they are taken their time as no doubt there is a logic x around the corner which will built to handle this.. and we'd have to buy the upgead stop the "lagging!"?

I also romoved mission control from the dock, + with all the other chanegs, my computer has speed up quite!

nope this did not work for me.... Im really loosing my patience with logic waiting for an update...

I have never had any of those features enabled, and this problem started in Lion before those features even existed.

"... I had a very lengthy and totally (and refreshingly) honest conversation with the Senior Product Manager of Logic Pro and came away very encouraged. He told me that, first of all, they are trying very hard to fix this problem, but that unfortunately it's just not easily reproduced. ...".

We've seen similar comments months ago.

Please suggest your contact person to carry out a remote session with a user who suffers under the lag, e.g. using NetViewer or TeamViewer. Then the Apple Support doesn't have to try to reproduce the error for months anymore.

The way he explained it to me was that it most likely is indeed a Mountain Lion issue. But they need to be able to reproduce the issue with ease for the the Mountain Lion crew to make a priority of it, and that's the tough part for them. They really are trying, it's just a very complex problem, apparently. But I am totally confident that 1) they take this VERY seriously and 2) they are working hard on solving the problem.

Nick, your fix did not work for me at all. NOT A FIX.

As they are so worried I propose this:

Anybody here is interested in exchanging a lagging problem MAC for a totally brand new model, full memory, top speed cpu, clone it and send the old one to MAC EXPERTS so they can figure out?

That shoudln't be a problem for a company that care about customers. They would be really grateful!

And believe it is less expensive than the salaries of all that poor people trying to reproduce the problem for ages...

What a shame mine hasn't got that problem...!

;-)

Why can't they carry out a remote session with a suffering user? If they did that, I would accept that they are take this issue seriously. Otherwiese we can wait until we are totally fed up. My trust in Logic is decreasing - is this a product to count on for future investments?

Can i reiterate that having manually downloaded the garageband app, even though I already had it on this system, did seem to drastically improve the lag issue. The GUI of the channel eq still flares when moving the levels etc but overall it is a drastic improvement.

Utterly confused and frustrated.

For weeks, since the 9.1.8 update, Logic has been running smoothly on my two systems (Retina MBP, OS X 10.8.2 and 2009 iMac i5, OS X 10.8.2). Previously, I'd been experiencing the GUI lag to the point where I purchased Studio One V2 to finish projects.

Suddenly, this week, the lag has returned. Even when using a VSTi (Audiorealism ABL2), and sometimes with projects that are merely audio and no plug-ins, third-party or otherwise. I'm completely stumped with why this should be: I haven't made any changes to my system in between Logic working perfectly and now.

Roll on 9.1.9....

Paul,

So you don't have "Automatic Updates" selected, you do ALL updates manually?

Ah....now, I thought I had automatic updates turned off, but it appears that - possibly when I recently did clean installs of Mountain Lion - I've messed up.

I guess this might explain the sudden issues? Sadly, I also imagine there's nothing much I can do about it.

Actually, it looks like I absent-mindedly installed the 10.8.2 Supplemental 2.0 update three days ago. As much as I'd like to think Apple have got their Logic act together, I wonder if this is the culprit.
