Hey everybody,



I have a solution that worked for me.


Quick answer:

I deleted all plugins that ended with 'x64' from the Components folder (HD>Library>Audio>Plug-Ins>Components)


In my case they were:

  • Nexus x64.component
  • Quartz x64.component


And it worked! Although it still takes about 1/2-2 minutes to load Logic every time. Before the update it was only a matter of a few seconds. Which means Apple still has to address the lengthy plugin rescan process on every single launch with this new 10.5.1update.


How I figured out that those files were bricking my Logic?


I used the following algorithm:

  • I emptied the bin before proceeding.
  • I created a reserved copy of Components folder.
  • I emptied the content of the original Components folder.
  • Then I started to RightClick=>'Put Back' every single plugin 1 by 1 from the Bin which was automatically added back to the original Components folder
  • I was restarting the system with every single add.
  • Launch Logic Pro
  • Sometimes I sped up the algorithm by combining the less likely suspicious plugins from the same developer eg. Soundtoys, FabFilters, Arturia, Native Instruments - I batch 'Put them Back'
  • Tagged all non-problematic plugins with various colours. Just in case I had to start over and I'd already know that those plugins could have been safely put back in the Components folder.
  • I obviously suspected DIY and Trial plugins to cause the problem. But in the end I found out that my brickers were the files with x64 in their name.
  • It took me 4 hours to achieve the result. I had to process 229 plugins in total.


Hope this helps!

Thank you.


PS.

My set up:

MacBook Pro (Retina, 15-inch, Late 2013)

Catalina 10.15.4

iLok 2

I have a lot of DIY, freebie, lite, expired trials, no longer supported plugins

I don't have any illegally acquired or 'cracked' plugins installed

I think that I possibly did not remove enough. I had plug-ins from Kontakt, Izotope, and PianoTeq. I only removed the portion that seemed to be embedded in my Logic files. So I have now removed all of those separately, just for existing on my drive, having nothing to do with Logic. Again, I removed my main Logic Application and I feel that I have gotten rid of anything on my computer that could be incorporated into Logic later. I went back and downloaded Logic and I’m just now running it and I see no change, as it still seems to be in the endless loop of letting me know that it is updating the audio unit plug-in information. I’m willing to wait for an hour or two but I’m afraid that if this continues until I’m ready to go to bed, which will be in six or seven hours, then I really don’t have any other ideas?

If I hadn’t had everything working perfectly with Logic 10.5 then I might agree that it’s possible that my system is too old, but with four years of perfect operation and then everything crashing with a one decimal point upgrade it’s difficult to believe that my four year old MacBook Pro is suddenly insufficient. I am still going through the long arduous process of completely starting from the ground up with the re-installation of Catalina, followed by the meticulous installation of each application that I had removed. It seems like it should work, but I’m also suspicious that I shouldn’t have had to go through all of this, that I have never had a previous problem.

hello, Apple?!

anybody home?!?!


hello hello hello, Apple... anyone...


I feel lucky in that my Logic is still working fine, and the workaround I have to perform EVERY TIME I NEED TO USE LOGIC is thankfully short and easy.


because it sounds as if there are users out here spending HOURS of their own valuable time doing Apple's work for them (for free obvi).


seriously, Apple, we desperately need you to be looking at this and letting us know how long this is going to take for a fix. talk to us!


thank you,

Had this happen to me this morning...the beach ball when opening logic x. So I found this discussion page this morning. Today is July 11th, 1 month after these postings...and no new postings or info or fix? Are you kidding me? This is nonsense. I’ve been debating for quite awhile about moving to Studio One or Pro Tools and if this isn’t rectified rather soon I’m done with Logic...which is a shame because it has some great features (and I’m used to it). But if it takes over a month to get a fix just to make it usable then something is really wrong here. Even the month old suggested workarounds can’t be tried because you can’t open logic to begin with! A month? Really?
