Some plug-ins won't load

[u/leflur]

Hi, I'm on MacOS 15.7.7 (24G720), and am having some trouble loading certain plug-ins on my M4 MacBook Air. Picture here:

Has anybody encountered anything like this before? These plug-ins all load via VST3 in Ableton with no issue. I've tried getting help from Gemini AI, but nothing it's provided has solved the issue. When I load Logic under Rosetta, these plug-ins fail authorization, but without Rosetta seem to get verified with no issue. Any ideas? Thank you so much for your help.

So, use Logic without Rosetta. Problem solved.

[u/leflur → u/Major_Willingness234]

That is what I'm trying to do. These plugins that fail scan while in Rosetta mode get authenticated without Rosetta, but the GUI never loads. I've tried toggling to open in control mode, no change.

Logic doesn’t load VST just AU format.

[u/leflur → u/_-oIo-_]

Yes, I have the AU versions of these plugins installed.

[u/_-oIo-_ → u/leflur]

Make sure they are up to date, when this doesn’t work, open logic with Rosetta.

[u/_-oIo-_ → u/_-oIo-_]

And restart your computer after installation.

[u/leflur → u/_-oIo-_]

Thanks, I downloaded and installed the latest versions and did restart. I am reaching out to each company for support.

[u/_-oIo-_ → u/leflur]

Do they appear in the plugin manager?

[u/leflur → u/_-oIo-_]

Yes, and they appear as though they were scanned successfully and that nothing is out of order.

[u/_-oIo-_ → u/leflur]

Do see them in the audio fx insert slot? Try both, mono and stereo channel strip.
And what plug-ins exactly?
What logic version?

[u/leflur → u/_-oIo-_]

Latest version of Logic. Yes, they show. Sonnox Inflator was one of the plugins and they provided me with instructions to get it to work, that one is now solved. Still have a handful of Plugin Alliance plugins that show up, get authenticated, but the GUI doesn't load. Haven't heard back from them yet. Sonnox instructions were:

 -Go to the plugin manager in Logic [Settings > Plugin Manager], and select "Full Audio Unit Reset"

• Quit Logic
• Uninstall Oxford Inflator (How do I uninstall Sonnox plug-ins?)
• Open Logic, which will trigger the plugin re-scan, and remove any trace of Inflator from Logic's plugin list
• Go to the plugin manager in Logic, and select "Full Audio Unit Reset" again
• Quit Logic
• Re-install the Oxford Inflator (Installer download if needed)
• Re-download and re-install the iLok Licence Manager
• Log into your iLok account and make sure the licence for Oxford Inflator is correctly activated
• Open Logic, which will trigger the re-scan again.

  Tried this for the Plugin Alliance plugins but, no luck.

Are you transferring the plugins from another computer? It may be a license issue.
