Logic Pro 9.1.8 + Mountain Lion 10.8.2 - Frequently crashes when using plug-ins
I'm really hoping someone can help. I suspect this problem is new since I can't find a definitive answer.
When using the third party plug-in Superior Drummer 2, Logic Pro 9.1.8 frequently crashes giving problem report 'Logic Pro quit unexpectedly while using the Superior Drummer plug-in' followed by details.
This also happens when using Arturia Analog Laboratory. Similar problems have been reported by others using third party plug-ins.
Some have suggested removing the folder /System/Library/PrivateFrameworks/ProKit.framework and then installing ProKit Update 7. I've tried this without success. Once removed, attempting to install it only launches the alert 'a newer version of this software is already installed', which it patently isn't. Removing it also prevents Logic Pro from launching and requires the reinstallation of Mountain Lion.
Others say it's a problem with Mountain Lion and even Lion. Apparently, the above fix works with Snow Leopard but unfortunately, since I downloaded Snow Leopard from the app store, I can't revert back because it's no longer available.
I don't know whether the problem is with the plug-ins, Logic Pro, or the operating system but I do know that this is not uncommon. I haven't yet found anything to implicate the plug-ins. All have been updated to their latest versions. I can not verify whether the plug-ins worked in previous incarnations, with a previous operating system or Logic Pro since I've only ever used them with Mountain Lion on a MacBook Pro Retina 2.7 GHz Intel Core i7, 16 GB 1600 MHz DDR3.
The current cacophony of forum discussion is roughly sounding out Mountain Lion as being the issue.
I'm in the dark here! HELP!!!
