Logic Pro unexpectedly quit and now won't open at all please help!!

Hi all,

I have a Macbook Pro, 10.7.5 - just the standard one. I use Logic Studio (Logic Pro 9) and normally it works fine but the other day I tried to bounce a track and I got the beachball of death and the message 'Logic Pro has quit unexpectedly, a version has been saved xxxxx (crashed) etc'. This happened everytime I tried to save or bounce or import, in any session - a blank one, or an old one.

So I did some research and on an apple support page ended up deleting the 'Prokit' thing from my library, and downloading the new one (Prokit update 7 I think). I tried opening Logic again and got this message:

'Logic Pro cannot be opened because of a problem.

Check with the developer to make sure Logic Pro works with this version of Mac OS X. You may need to reinstall the application. Be sure to install any available updates for the application and Mac OS X.

Click Report to see more detailed information and send a report to Apple.'

I gave up a bit at this point, and thought I'd uninstall/delete every trace of Logic from my laptop, including the items in preferences (this was recommended online somewhere). I went through the (lenghty!!) process of reinstalling Logic and all the audio content and extra CDs, and the problem is still exactly the same and I can't open Logic.

Can anyone please help? I'm lost without being able to use Logic every day, any advise would be great!!

And I've also just updated Logic and still no luck.

Thanks,

David

Logic Studio, Mac OS X (10.7.5)

Sounds like you may have trashed some important System files.

It would be worth taking a look at the "more detailed info" in the crash report and posting it here.

Other than that,

If you have already been through the "Trash Logic Preferences", re-install Logic from scratch routine, I would suggest

a) Make a safety clone of your entire HD using Carbon Copy Cloner or similar,

b) then re-install the OS and any subsequent OS updates. You could do this using the Lion Recovery disk, or download the Lion Installer from the Appstore directly.

I didn't see your post (CCTM) and downloaded the one Pancenter recommended. I tried opening Logic and got this...

And then I downloaded CCTM's link and get this:

I'm still getting the yellow weird things when trying to open Logic.

Not gonna lie, I'm completely in over my head and don't know if I'm making this better or worse, thanks for the patience and help guys, I really appreciate it.

In that case, I 'd again suggest that your best course of action (with a full backup of the existing drive for safety) would be to re-install the OS.

You should be able to do this via Lion Recovery:

You should be able to re-install the OS on top of the existing one without issue, and then download and install the Combo updaters if they are needed (probably not).

Great, thanks. My external hard drive is only 160GB (got it for my old macbook), am waiting on delivery of a bigger harddrive so I can back up and then will try reinstalling and let you know what happens!! 🙂

David,

In the meantime, try installing the latest Prokit from here.

The Dialog box you're seeing is indicative of a missing prokit framework file.

Have tried that, and just get a message up that i've already got the latest version...

Have backed up and reinstalled, and so far so good!! lots of catching up on work to do now, but it's saving and bouncing and all seems to be in order and I'm not missing anything.

Thanks to both of you for your patience and help, it was really appreciated.
