Logic Pro X ignores many AUs

[kovacs]

Hey folks,

I have suddenly ran into an issue with Logic Pro X.

I have a 2016 MacBook Pro touchbar 15" running macOS High Sierra (up to date).

Logic Pro X is running fine without any issues - apart from several audio unit plugins which are being ignored by LPX.

Some plugins install perfectly, but others are not discovered at all.

I have:
- uninstalled and reinstalled LPX
- repaired permissions (disk + folders)
- removed and reinstalled plugins

So the entire Logic Pro X on my machine was installed *after* upgrading to High Sierra, and not upgraded.

Examples of plugins I struggle with:
- Xfer Chtulhu
- Dmitry's Tantra (my favorite plugin)
- Air Hybrid3

They are installed and permissions seem ok, but Logic refuses to add them (they are not even listed in the plugin manager).

Some that work fine:
- EZKeys
- Voxengo Elephant etc, I have 5 and they all work
- Dmitry's Thorn
- NI Solid Bus Comp

I have tried to search for relevant content online but have come up short.

Has anyone else experienced anything like this?

High Sierra

That's the reason of your problems. If possible - downgrade to Sierra or El Capitan.

But what exactly is the problem?

I'm not going to High Sierra here, but previously if some plugins didn't validate in Logic, the fix was to downgrade auvaltool to a previous version.

Maybe try that and see if your AUs validate. If they worked fine in Sierra, try that version of auvaltool.

[AdamWysokinski]

First thing to try is a restart. Many plugins will be validated by Logic after a restart, for remaining you have to wait until developers update them for HS.

But what exactly is the problem?

Every OS X upgrade brings a minor change on Audio Units and auval app (the application that validates audio units on Logic Pro X/Mainstage). A common trick was copying an old auval from previous OS X version, but I don't know if it still works.

Ok, thanks guys. I have of course rebooted a number of times already, but due to the magic «just one more time» theorem I now see Hybrid3 and Chtulhu MFX (but strangely not the FX one).

The plot thickens.

Download & install Two Notes Sandbox Patch plugin
Reboot your Mac

This au validation issue, and the number of times it cropped up when os updates come out, is the main reason I kicked mac out of my life. There's most likely a fix for this one, but it'll happen again. I looove Logic, MacOS not so much

You know, if you wait a few months after a major OS update comes out, all the various issues get resolved. Nothing forces you to do a major OS update immediately.

High Sierra was released on September 25, so that is already a few months ago.

Not a single problem here on High Sierra and I have several hundred of plugins working in Logic.
Which version of Logic are you currently using?

Which version of Logic are you currently using?

10.3.2

Note that I also don't see the "ignored" plugins in Garageband, but I guess they use the exact same plugin validation.

I've not had any trouble with any plugins in Logic... also 10.3.2 and High Sierra
