VST3/AU, Ableton: "Cannot be opened because the developer cannot be verified"

[kristianpedersen]

Ableton Live 11.0.12
MacOS 12.0.1
JuicySF 2.3.3

Happens with both VST and AU.

If this were an application, I'd just open it in Finder, right-click, and open.

It did show up here (.vst3), but allowing it to run didn't have any effect.

I also tried following these instructions: https://www.reddit.com/r/ableton/comments/galkk3/macos_catalina_10154_and_vsts_vst_cannot_be/, but spctl wasn't available, and then I gave up and kept making music for a couple of hours. 😃

did you try the other suggestion:

xattr -rd com.apple.quarantine juicysfplugin.vst3

[kristianpedersen]

That worked!

For anyone else struggling, this is what I did:

1. Open iTerm
2. Paste this: cd ~/Library/Audio/Plug-Ins/VST3
3. Enter open . to open Finder, and copy juicysfplugin.vst3 from your download directory
4. Paste this: xattr -rd com.apple.quarantine juicysfplugin.vst3

If step 2 fails, you might need to create a VST3 folder there first:

1. cd ~/Library/Audio/Plug-Ins
2. mkdir VST3
3. cd VST3
4. Then you can follow steps 3 and 4 above.
