Logic X crashing since 10.2 update

Question

Hi, Since the Logic Pro X 10.2 update my system has been crashing regardless of trying any of the fixes that have been suggested elsewhere.I have tried to resolve any permission issues with no luck. All files are save on my internal hard drive and have not been moved off and back on again. If I open a Logic Pro session that previously had no problems and hit play, very quickly I will get an error message telling me "Disk too Slow" or "System Overload". Having only played a few seconds of audio. This will continue until the system finally crashes. I am running 64 bit Steve Slate drums as a multi timbral midi instrument and I am running 5 tracks of audio with that. I am running all plugins native to Logic bar one. Tokyo Dawn Labs EQ. All of which worked fine up to the 10.2 update.I am doing nothing to prompt the issue, like running a reverb on every channel or something. Any information on this would be helpful.Thank you.

If you create a new Admin account, log into that and then run Logic.. do you still get the same issues?If you open logic without any project loaded... and then create a new project using just Logic&#x27;s internal plugins.. do you have the same issue?Failing both of these.. please post the crash log up to Dropbox for example.. and paste a link to it here....

Hi,Thanks for the reply.Unfortunately the creation of a new admin, while it did allow Logic to play, Logic opened up reskinned as Garage Band and my multitimbral instruments were down to a stereo midi track.I always have Logic load without opening a project. But when I&#x27;ve tried to start a new project, say two tracks of audio, the same errors appear even without running any plugins in the session.Unfortunately, I am in China now for the next 10 months and I am unable to use Dropbox without a VPN (which at present I don&#x27;t have).The issue presented itself the day I was leaving. Which is typical. I have the crash report saved, so if you can think of another way of me getting it up to be viewed let me know.I have uninstalled and reinstalled Logic X with no success. I have run permissions repair with no success.I have checked the permissions of the audio folder, path of the audio files all with no success.Logic was working fine until I updated it. Thank you

Unfortunately the creation of a new admin, while it did allow Logic to play, Logic opened up reskinned as Garage Band and my multitimbral instruments were down to a stereo midi track.That is because you haven&#x27;t re-enabled all the Advanced Tools in LPX&#x27;s preferences..... under the Advanced Tools tab... so LPX is still running in &#x27;GB Pro&#x27; mode..Do that and you should be fine..Note: If Logic does indeed then work fine under a new Admin account, your issue was/is related to permissions..... with your original Admin account.

Hi,Thank you for your reply.I clicked on the Advance settings and yes I got full Logic Pro back. However, running the session in the new admin account resulted in a crash. I moved the files over to the new admin account side and loaded the session from there.Which also resulted in a crash.I am now at a complete loss as what the issue could be.Thank you.

PPlease copy and paste the first half of the crash report up to the end of the threads section.... Into a post here....

Hi.This is from last nights crash report on my original admin. I forgot to save the new admin crash log as a text file.

That crash appears to be caused by the Slate Digital plugin....I cannot be 100% certain because its hard to tell &#x27;remotely&#x27; like this... ..but it looks very likely based on that crash report.....

Damo Mc · Answer

Hi,Ok thanks.I will try run the session without Slate Digital.This plugin was fine before the update however. If this fixes it I will let you know.

Damo Mc · Answer

Hi,Thank you again for your help and insight.However I removed Steve Slate from the session. I removed Steve Slate from the plugin in manager.I shut down Logic. Opened  up another session and only used audio. System crashed as before. I am pasting in the crash report.

Well, as it&#x27;s not Slate and I dont see any other plugins running..However, something is tripping up the Plugin Input Bus List somehow...The only other things I have ever found to cause that sort of issue were;1) An out of date or incompatible Audio and/or Midi driver.... Check for updates and compatibility with OS X 10.10.5 (as that is often what really matters)2) A plugin wrapper of some kind (like 32Lives or Novation&#x27;s Automap for example) which after an upgrade would mess things up....3) An installed but not used incompatible plugin when it corrupted the plugin list...  Both Slate and TDL have been reported as being a little flaky at times.. so try uninstalling those completely (delete them out both of  the two Components folder if needed) Restart your Mac and then test Logic and see if it still crashes....4) (An off the wall one but once this was found to be the issue) If you are using more than one Monitor... Shut down your Mac, unplug the second monitor and then restart your Mac and test Logic...If it&#x27;s none of those, then whatever it is, is beyond my skills and knowledge/experience... and so maybe one of the other regulars here, might have a few ideas...or failing that.... ask over on LogicProHelp.com as maybe David, Eric, Jordi or one of the other regular users over there.... might provide a clue...Last resort, contact Apple directly but don&#x27;t hold your breath on that one....One last thing.. If you do find a way to resolve this issue, could you please let us know here as it may be useful to help others who come across the same or a similar issueGood luck,Nigel

Hi,I tried the recommendations above and none worked unfortunately.Even deleting all non native plugins from the Components folder.However, just like you, a friend of mine suggested pursuing the permissions issue further.So I downloaded and used ACLr8 to repair permissions via terminal as nearly of of my permissions were throwing up warnings such as "ACL found but not expected..."So I let it run and the result was this:Last login: Tue Sep 15 08:16:46 on consoleDamiens-MacBook-Pro:~ damienmcevoy$ /Applications/ACLr8Password:Welcome to ACLr8 version 1.4.Press Ctrl-C to stop the program at any time.Reading permission errors (this can take a very long time)... done.Found 2126 files with unexpected ACL.Removing ACL from all files...

Yes, Im pretty sure that is part if not all of the issue... To test... Simply create another new Admin Account in System Prefs &gt; User and Groups... (Don&#x27;t use the opne you created earlier but make another new one)Log into that but do not move any files over.... as I noticed you said you did that during your earlier attempt.Instead create a new Project in Logic and test with that....

Ok. I will try that. And I&#x27;m sure it will work.However all of my audio is saved under my other profile.As I am in China without a VPN I cannot get any of the original files back through dropbox etc.I don&#x27;t have access to other audio to insert into the new sessions under the new account.What do you suggest I do?

Well, lets take it one step at a time.. and do the new Adnin Account without moving any files around just to see if that does indeed fix things...If it does, then we can work on how to sort your moved files out so you can continue work..If it doesn&#x27;t work then you may have to start again from scratch and re format your System Drive and reinstall OS X and LPX... as that is typically the only real way of fixing such permission related issues.. But.. again, lets first of all see what actually happens with a new account and a new project I will be in the studio for the next 8 hours but I will respond back when I get out of there......Cheers..Nigel

Hi Nigel,Sorry of rate delay in replying. Classes started here this week and I&#x27;m still trying to adjust. Thank you again for all your help in the matter.I have set up and new user account and ran Logic.It ran fine, bar when I was adding soft synths while it was looping midi. It stalled 1-2 times in a hour of use but never crashed.I don&#x27;t have audio to run so I&#x27;m not certain that the issue is fixed. I have been having issues else where on my original profile.For example when typing the cursor stalls and every few seconds has to catch up with my words.I&#x27;ve ran a virus scan but nothing there. I don&#x27;t have that issue on the new profile either so it seems my original profile is wrecked.I reinstalled OSX Yosemite this morning hoping to fix it but no luck. I tried opening the  logic session a ran on the new profile, from the old profile. My old profile, even though it is an admin profile, doesn&#x27;t have permission view the new profile&#x27;s folders. However, vice versa I do. If the new profile is a &#x27;fix&#x27; how do I port my existing files over to the new profile for using?
