Mainstage Crash during live use after OS X 10.7.4 install.

Go back to 10.7.3 e.g. via your Time Machine backup.

I had this problem too and I *think* I have it fixed. Wanted to share in case this was helpful for you. Check to see which version of Mainstage you're running. If it's 2.1, chances are you are running a copy from Logic Studio... which is no longer updating. MS 2.2.1 is out on the App Store, and so far seems compatible with the 10.7.4 OS update. Hope this helps.

PS, apple, if this truly is the case, it's a shame you couldn't at least warn us that our copies of MS would be obsolete. This happened right before a gig for me. Shame on me for blindly updating, but it could have been avoided.

I downloaded and paid for the Mainstage 2.2 and it wont launch in 64bit and crashes every few minutes in 32bit. Also my macbook pro runs so hot now I'm afraid there will be damage in my future. THanks a lot Apple!

Hello All,

Right had fun and games on a gig last week where MS was crashing during sound check. Thank fully it was OK during the gig.

Been trying to get it to crash over the past week and it won't do it!!

Is 10.7.4 now stable? Also nobody else seems to have written about this issue in the past week....

Anybody got any ideas?

Cheers

James

Anybody know what the official word is on this crashing problem with the OSX 10.7.4? Is there an offical workaround? Or should I officially avoid upgrading Lion until MainStage is revised? I use MS professionally and can not risk crashes during live performance.

I think the tip with the toolbar came from Apple. I am sure Apple is working on a better solution right now.

Thanks, Blueberry. And have folks had reliable success with the toolbar tip? Did it not work for anyone out there? Thanks, all....

And there is your reply from Apple:

About the MainStage 2.2.2 Update

Stability and Usability

• Resolves an issue in which MainStage might quit unexpectedly on OS X Lion v10.7.4.
• Resolves an issue in which MainStage sometimes quit unexpectedly when loading certain concerts.
• Resolves an issue in which MainStage quit unexpectedly when a second mapping was assigned to a screen control that already had a mapping assigned.
• Fixes an issue in MainStage 2.2.1 in which assignments and mappings could be inadvertently deleted by removing a screen control in Layout Mode.
• Resolves an issue related to the download and installation of basic and additional content.

Compatibility

• Resolves an issue in which patch lists were not updated to VAX and Axiom keyboards if the keyboard lost and then regained connection to the computer after launching MainStage

General

• Resolves an issue with MainStage 2.2 and 2.2.1 in which EXS instrument files were not available if they were in aliased folders.
• Fixes an issue in MainStage 2.2 and 2.2.1 in which the I/O Plug-in did not route audio to outputs.
• When mapping a Screen Control to a parameter already mapped to another Screen Control by using the plug-in GUI, MainStage now correctly maintains independent mappings for each Screen Control.
• Resolves an issue in which using the Command key in conjunction with up and down arrows in Edit mode with Map Parameters enabled caused MainStage to assign the mappings to Next Patch and/or Previous Patch.
• Fixes an issue in MainStage 2.2 and 2.2.1 in which mapping a Screen Control to jump to a patch or a set no longer worked.
• Screen Controls mapped to more than one parameter now operate smoothly over their entire range with all range scale settings.

Great news. This update promises to also fix a few problems I have had with Screen Controls. I'll wait to hear from others on how the update went for them; as a rule I will only update when there is plenty of time to test things before a gig...
