Backbone not loading in Logic

Installed on 2 different computers and on both it doesn’t show up in the list of VST Plugins. help!!!

Have you made sure to use the latest version of Logic and the eLicenser Control Center? The latter can be downloaded at

Yes, everything is up-to-date.

I cannot reproduce this here. For more help, I’d need a detailed system overview (which Mac model, which OS exactly, which Logic version exactly). Also, does the Logic Plug-in Manager list Backbone?

Model Name: iMac
Model Identifier: iMac19,1
Processor Name: 6-Core Intel Core i5
Processor Speed: 3.7 GHz
Number of Processors: 1
Total Number of Cores: 6
L2 Cache (per Core): 256 KB
L3 Cache: 9 MB
Memory: 64 GB

OSX 10.15.6
Logic V.10.5.1

The plug in shows up in the plugin manager and there’s a check mark that all is ok. But it won’t show in the list of plug ins when trying to select in the drop down in the actual Logic environment.

Thanks! I am still unable to reproduce this here at work. Backbone shows up just fine.

Have you tried a complete rescan of the plug-ins as described in here?

I have done all of the above…nothing…

I have rescanned an trashed cache,etc. all of my other plugins load with no problem.

Have you been in contact with the Logic support on this matter? Maybe they have more ideas as to why this happens.

Hi yurigevrasev,
unfortunately there’s nothing we can do to eliminate this issue right now.
We’re in contact with apple and we hope that they will provide soon a fix for Logic or tell us what we have to change in our plugins to solve the problem.

A possible workaround from the LogicProHelp forum is perhaps this one:

Finally I created a new admin user, started Logic and after the validation of the plugins I could create a new empty project with an instrument track. And YES, the Steinberg menu was there, I could use it again.

I just bought Backbone with the sole intention of using it with Logic and i have the same problem here. How is this happening?

Had the same problem. After installing and authorising I restarted my iMac (Catalina) and Logic suddenly found it.

I hope they resolve this soon! Love to be able to use Backbone in Logic.

Please have a look here :

best regards
