Logic Pro 10.7 very slow on loading projects and plugins

I just got off the phone with Apple Support about this issue (a call I scheduled with their Pro Media folks yesterday). While I was on hold I started to do a little debugging.

I started with a fresh project with a 10-second blank audio recording. Then, I saved it and opened it back up. So far so good, nice and fast. Then, I added RVox, a Waves plugin. I saved and closed the project and tried to re-open it. Bingo. Slow!

So then I started searching the Internet for slow Waves plugins with Logic Pro. I came across something that said I should run "Waves AU Reg Utility" which basically scans your plugins and registers them as Audio Units. I ran that utility and it said it errored out, but when I launched Logic Pro again with that test project it opened up right away!

I then tried opening one of my projects that has been really slow. Zing! It opened up with no delay.

Then the Apple Support person came on the line and I told him that I think I had solved it. Fortunately he was nice enough to explain that ... if you are running on macOS Monterey, plugins will only work properly if they are registered as Audio Units.

He send me a link to a document that explains some things you can do to troubleshoot Logic. Hopefully this also helps someone else here. My projects are all opening nice and fast now. I wish I would have discovered this two months ago.

Here is the link to that document: https://support.apple.com/en-us/HT201199

I'm running on a MacBook Pro M1 Max w/ 32GB RAM and hitting this issue. Using Logic Pro 10.7.1. I didn't start noticing it until I started putting in some plugins from Waves (RVox and VU Meter). I've also got some FabFilter plugins scattered throughout my project.

If I use Finder to tell Logic to open using Rosetta, my projects open really quickly. I thought that the Waves and FabFilter plugins have native support for M1, but for some reason they are seriously bogging down my projects. Opening projects, switching the audio interface, copying and pasting channel strip settings, etc.

Check if you have your HD excluded from Spotlight.

I had the same problem because I had Monterey beta installed on a second volume and therefor I excluded Monterey from Spotlight when I'm on Big Sur. After release of Monterey, I erased the Big Sur volume and Monterey was still excluded from Spotlight search. Without activated Spotlight, Logic does not work correctly.

Hi Bubb1eboy did Apple ever get back to you? You mentioned that you were in contact. I don’t think Apple officially monitors these forums as other more customer friendly software and hardware providers do.

in view of all the crashes observed it seems that Logic 10.7 not always properly scans all plugins used in projects upon opening despite the long time it takes to do that. It should come back at opening with a clear message that it found 1 or more incompatible plugins best mentioning them by name. it unfortunately only notices when the plugins are used in a track that they are incompatibility and then it blocks or crashes. I saw that Spitfire audio has betta versions of some of their libraries and related plugin and you have to switch dependent on the mode unison, M1 or Rosetta. Unison should be compatible for both modes but you apparently still have plugins which can only work on M1, plugins which can only work using Rosetta on an M1 machine and those who work on both. So with situation you can get crashes in both modes.

Apple have not been back in touch as yet. I filed an official support request through their feedback. They acknowledged receipt and had a quick chat about the issue and I sent a complete support profile and sample of the code contemporaneous with the faults and hangs. I seem to be having the same problem as others. Mainly with Slate digital plugins. Ive never run in native M1 as my third party gear is not up to speed with being compatible yet. Frustrating. I’ve given up on 10.7 and gone back to 10.6.3 and everything is perfect running under Rosetta. I’ll hold tight until a fix comes through.

We are in precisely the same boat. It has rendered my workflow impossible. Slate infinity eq is the most obvious offender. Takes forever. I’ve gone back to 10.6.3 just so I can work normally again. It’s obviously a software bug as it’s occurring across ARM and Intel machines. Under Rosetta and M1 native. I feel your pain.

Just came to this thread to say "same here". Reverted to 10.6.2 and everything is running much better. 10.7.2 seems more bugged. I'd say this is a critical problem at this point. It's deeply affecting my workflow. I need to finish Atmos projects that are simply failing to load 70% of the time. It's extremely frustrating. Apple needs to push a hotfix.

Confirmed it has to be an issue with 10.7. If you have time machine just push to an earlier backup of logic, 10.6.3. I switched it after having issues tonight & it’s a completely different story.

I've been forced to return to Logic 10.6.3 and everything is working again as it should, super speedy and no dramas at all. 10.7 was totally unworkable. I guess I'll be waiting until the issues are resolved.

If you go to a backup from before the upgrade, you can just restore the app. I use time machine so it’s easy. Right click on the 10.6 version on your backup and hit restore. It should ask what folder you want to restore it to…( applications)…if you want to replace the existing app (10.7)…hit yes and it will copy it back into your app folder and you’re back to 10.6.

Make sure you turn off auto updates, or you’ll wake up tomorrow back to 10.7

I don’t know what to do if you don’t have a backup, sorry.

Thank you bubb1eboy that's spot on! I didn't realise you could just revert single applications from time machine. Now back to 10.6.3 and I can work again without making 10 coffee's a day waiting for my projects to load!

Oh rats.

The support guy did say that stuff like this is most likely related to a specific plugin. Have you tried creating a blank project and then adding plugins one-by-one until you discover the culprit? Or, have you followed the steps recommended in that document? If it's related to a specific plugin you are using it could be that all you might need is an upgraded plugin.

Also, if none of that works, you might try scheduling a call with their Pro Media team: https://getsupport.apple.com

The issue (slow project loading) is definitely not connected with the specific plugin. Project is simply loading slowly in general, because each plugin loading takes more time. It takes me ages to load standard project, and it is connected with the latest update. It is killer for everyday work. I have just tested it - I loaded mid sized project for 2 and half minutes. Bigger projects takes 3 min or more.

As for the loading of the Logic in general, it is slow as well, however as already mentioned Waves play important role in it. It helped me a bit to unify all the plugins to the latest version 13.

Logic 10.7.2

All my work has been in Rosetta. The most important of my plugins are not yet native compatible. Any of my projects I try to open in M1 native crash logic on opening. Logic just vanishes. I’m on an M1 mini. I’ve not yet tried to save a 10.6. (When they eventually open) as a new 10.7 file. I’ll give that a crack. I’m tempted to upgrade to Monterey and see if that solves anything but frightened because my high end plugins aren’t supported yet.

it seems Slate Digital are the main culprit as they take ages to load on insertion or when being altered. Yet Kush stuff works beautifully once the project is open. Even apple plugs seem to cause hang when opening projects.

🤷🏻‍♂️

Hello --- urging all users on intel based mac to downgrade to 10.6.3 where logic was beautiful, fast, responsive and snappy, and also prettier.

I couldnt do it through time machine so i just torrented it. It worked and now im able to work again. I am still a paying costumer for apple and have logic pro purchased, so im frankly disappointed and feel my money was not put to good use with this latest 10.7.2 update.

Rest assured 10.6.3 works great. Cheers
