LOGIC PRO X ISSUES AFTER HIGH SIERRA INSTALL

Hi Guys


I recently upgraded my iMac 5k (late 2015) to High Sierra from Sierra. Before the upgrade, my Mac and Logic were running smoothly without any lag or issues. Since the upgrade I have been experiencing issues in Logic Pro X such as System Overload errors, lag when analyzing the EQ spectrum within EQ and higher CPU usage.

I started a project on Sierra, then continued working on it after the upgrade to High Sierra.

I always save current projects to the desktop for better performance on the SSD.

Before I upgraded to High Sierra, I made sure I checked for any updates for my apps and software, performed a clean in CleanMYMac and emptied any trash.

I then created a bootable USB drive from the high sierra installation file. I performed a clean install by formatting my SSD and installing a fresh copy.

I spoke to Apple Support about the issue and they suggested that I perform a reset of the System Management Controller and the NVRAM, which I done.

This made no difference to the performance.


Has anyone else experienced similar issues this or can provide me with a solution to my problem?

Any help would be greatly appreciated.

You have run into this behaviour due to the latest file system change:

https://www.logicprohelp.com/small-warning-updating-macos-10-13-high-sierra/


Read the article first and then follow this procedure:


  1. Quit Logic Pro X.
  2. Delete the Alias ~/Music/Audio Music Apps then create a new folder on this location and give it the name Audio Music Apps.
  3. Open the Terminal and paste this code followed by enter:
    open /.HFS+\ Private\ Directory\ Data?/

    - A new Finder window will reveal your hidden content.
  4. Copy the content inside the 'dir_######' folder and paste it inside your new Audio Music Apps folder.
  5. Relaunch Logic Pro X.

In Finder search for "Audio Music Apps" and one of the folders will have the folder directory like this:


User uploaded file


at the bottom of the screen right-click on ".HFS+ Private Directory Data?" and open it in a new tab. This will be the "dir_#####" folder mentioned in prior posts. Drag the contents of that folder into a new folder you call "Audio Music Apps" in your user/Music folder (after deleting the Alias in the same location).

Okay. Let me tell you how this played out for me... (FWIW I'm an old Unix guy)

- Logic was down, so I proceeded to step 2.


- Step 2 - that's not an alias, at least not here. It's a directory full of stuff. While somewhat reluctant, I deleted the directory (after emptying out all the files), and subsequently made a new one of the same name. (rm -rf/mkdir).


- Step 3. Copied and pasted as directed into a terminal. Didn't get a Finder window... I got a file not found error. Q: does that file exist on an HPFS or APFS system? In either case, it doesn't exist here.


- As a result of this step failing, those files in ~/Music/Audio Music Apps are 'gone forever'


Thankfully, I was able to recapture those files/directories from a recent Time Machine backup.*


I'd recommend that anyone who attempts this a) HAS A VERY RECENT Time Machine backup* and b) If something goes/feels wrong, STOP.


* Admittedly I was a bit of a cowboy using 'rm -fr' to remove the directory (no trash can). Smarter users can use Finder to do this and have the safety of the Trash Can.


Was the intent of this just to destroy a link/alias?

Apple hides systems folders from users so they won't screw up their systems and then proceeds to release an OS update that does just that.

I am having the same problems, everything fine on Sierra but the minute I switch to High Sierra I effectively can't use logic pro x as I keep having overflow issues. I even went out and upgraded my HD from Sata/standard disk to a SSD drive which is extremely fast for everything else but Logic. I am convinced it is logic that is causing the issues as browsers and MS Office all now open really rapidly but Logic seems to be stalling whenever it is asked to handle more than a couple of Virtual instruments. I have a late Mac Mini 2012 with 16gb ram and an SSD drive so in theory it should be flying.

I too have used clean my mac 3, which is a great little utility but as everything else gets a little quicker Logic Pro x just grinds to a halt. Any suggestions would be really useful as I think I am out of trying to think of solutions at the moment as I have tried nearly everything to get it back to what it was.

I'm having major issues with Logic Pro X after the High Sierra install. Playhead will not scroll, files can't be saved, can't quit the app without using forced quit, can't bounce tracks, the track window went black, loops library seems empty,


All worked great with Sierra, but High Sierra....... can't describe my frustration and level of being angry.

Nov 10, 2017 11:41 AM in response to DYEW1TNESS

Even more problems. If you are running Sierra and things work well for you in Logic Pro X, DO NOT upgrade to High Sierra. Then problems I am having are numerous and effectively make LSX unusable.


Here is my list:

Loops are gone

Playhead erractic (stops, doesn't play, sticks) This makes it hard to see where the track is playing

Can't save changes to logicx files created prior to pre High Sierra install

Can't close app without using force quit

Can't bounce tracks to anything without a crash

The Navigation bar and time counter in Logic X does not work properly


Those are the basic issues, can't even get deeper without being able to use simple tasks

Dec 5, 2017 9:56 AM in response to DYEW1TNESS

My suggestion is that you don't save Logic files (or any audio) to your system drive even if it is a SSD. All of those files should live on another fast drive. Even the sound libraries that come with Logic should be copied on another drive and create shortcuts to them. if this doesn't solve the problem, read don't the thread here and someone posted a link on another article with instructions; seems like there's a root level file that may be causing problems as well.


These kinds of issues are annoying and I've been through similar situations many times before. I hope you'll find a solution to your problem. As a general rule, I usually wait until the bugs have been resolved in new OSs before I take the plunge. Unless you absolutely have to upgrade, it's better to wait and let others be the "guinea pigs"! Good luck!

This is total BS. I buy a brand new MacBook Pro and get badgered to upgrade my OS. I ask one question about problems with new os and logic x which I was forced to pay hundreds of dollars because the new computer doesn't work with my logic 9. I get THIS which tells me to correct a problem within one or both of the programs, or maybe its a problem with my hardware??? The end result is that I have a computer that is brand new and cannot run the most recent upgrade. Do you really think that I will now trust high Sierra??? This overpriced , overrated, luxury brand piece of crap!!! Please correct me if I am wrong

Hi Wiilliam

This is an ongoing situation with a new OS, software, hardware etc.


I am still on El Capitan and will be staying here until I am forced to change, Logic 10.3.2 works fine, all stable.


However, I need a new computer, all new Macs come with High Sierra, so I have to buy a used one.

Or just wait until all the High Sierra problems are sorted.


Buying a new computer just as a new OS has been released is asking for trouble, even if the guy at the Apple Store tells you Logic will work fine!


I agree with you though, it *****, I bought Logic in the beginning foolishly thinking that there would never be a problem with it as it was bought from Apple!


Unfortunately you are learning the hard way, once you do eventually get sorted and stable, stick with it, turn off automatic updates.


Hope that helps a bit.

May 12, 2018 3:08 AM in response to DYEW1TNESS

Hello all, I have all these same issues, crashing, CPU spikes, freezing on save. I have the latest 2017 MacBook Pro, latest High Sierra, latest Logic X 10.4.1. I don't see any alias folder on the real folder in my home/music folder. And I get the same error when trying this process suggested "The file /.HFS+ Private Directory Data? does not exist." is all I get.


Has anyone had any success with solving this problem?


thanks so much

David
