MixBox presets not showing up in Garageband

[Wtptrs1985]

Hi, when searching the forum I noticed this has come up for a lot of other DAWs, but I cannot get any of the MixBox presets (either Factory or Artist) to show up in Garageband (they show up fine in MixBox Standalone). I read this is probably due to insufficient permissions on Mac and I've tried all the suggestions I read so far, but no result. I set permissions on preset files and folders exactly the same as the ones for Amplitube 5 / T-Racks modules, which do work fine in Garageband:

Code: Select all

# pwd
/Users/xxx/Documents/IK Multimedia

# ls -l |grep -i Mixbox
drwxrwxrwx@  6 root         staff   192 Oct 30 09:55 MixBox

# cd MixBox/
# ls -l

drwxrwxrwx  80 root  staff  2560 Oct 30 09:55 Effect Presets
drwxrwxrwx  12 root  staff   384 Sep 29 17:00 Rack Presets
drwxrwxrwx   2 root  staff    64 Sep 29 17:03 Song Presets

# ls -l Effect\ Presets/
drwxrwxrwx   7 root  staff    224 Sep 29 17:00 AM Modulator
drwxrwxrwx   7 root  staff    224 Sep 29 17:00 Ambience
drwxrwxrwx   7 root  staff    224 Sep 29 17:00 American Vintage
drwxrwxrwx   7 root  staff    224 Sep 29 17:00 Auto Pan
...

I also double-checked the steps in the following tutorial: https://www.ikmultimedia.com/faq/?id=1306

But the presets are still not showing up in MixBox when used as a plugin in Garageband.

Any other suggestions?

Thank you.
