Logic Pro 8 HELP! Crash on launch


Anyone know how to read a crash report log?

I can;t load L8 - it gets to load some Kontakt and ESX files then crashes.

I've reinstalled L8
Initialised the prefs
Re-installed Kontakt.
Started up with Alt

Repaired Permissions
Disk Warrior
TechTools Pro


Can't think of anything else

any ideas?

Hi Peter

If you want to attach the crash log here, there might be something in it indicating the source of the problem. In addition, it would be sensible to post details of your system. One culprit always worth checking for is melodyne rewire - an older version of this causes problems when launching Logic.

kind regards

If you have it set up to launch the last project, it may be that project that's corrupted.
You could try launching from one of the demo projects to check this.

Thanks Mark - it's odd - I can launch L8 fine off my backup drive ( when system booted from that drive)

Here's the latest log, following an 'empty' alt/launch and trying to load a simple autoload.

Mind, I can't recall if what I call a 'simple' autoload contains any plugins!


maybe I'll have to try my backup drive again, but first I'd be curious to see what you make of the crash log

See if pulling all the plug-ins out of the components folder gets at least gets the session open. This will let you know the issue is with a plug-in, which I suspect.

~ / Library / Audio / Plug-ins / Components.

Create a new folder in the Plug-ins folder called Components Disabled. Drag all the compenents into this folder and then launch Logic. If you can open L8, then you'll know you have a plug-in issue.

thx bob - that's a good suggestion, but I'll try first with the obvious - if it launches OK from my backup drive, then I can see immediately which plugins are always there.
Shouldn't be many - watch this space :)

I'm afraid that I can't see anything obvious in the crash log, Peter, although there is a reference to pro app kit, so it could be worthwhile checking if this is up to date. I emphasize, that is a very uneducated guess on my part ....

Did you send the crash log off to Apple? That is never a bad thing.

kind regards

hmmm. after following bob's suggestion and displacing all my plugins, and various other procedures ( a lengthy process of elimination which I won't go into unless anyone wants to know), whenever the output is set to imic/USB, any plugin in the main output strip will kill L8. Since this doesn't happen with my backup drive, it has to be a software problem.

But when I plug the iMic directly into the USB port in front of the mac, it works!

So something has changed on my main drive that doesn't show up on the backup ( about 2 days old).

go figure?

yep - and it's a quicksandy-type feeling - like - if its USB, then it probably ain't Logic - which is a relief - but if it's a software-induced stressing of a marginal hardware issue then where is my robust steed - the one that'll carry me to artistic and financial glory?
