If you have problems activating your plugins, please follow this Troubleshooting Guide for activation problems in Logic.
Please try the following steps in the listed order and try after each step if it works:
- Check if you inadvertently created a second Plugin Alliance account connected to your Installation Manager. The activation server will report that you don’t have a license if you don’t enter the same login credentials you used when you purchased your license.
- If you are using Logic 9, use the 64-bit version of Logic.
Our 32-bit legacy installer can be found at this link.
- Delete the plugins from the following folders and reinstall them.
/Library/Audio/Plug-Ins/
- Clear out the Audio Cache Folder to force a rescan
Click on the "Go" menu, then click on "Go to folder..." and paste this path: then type in:
~/Library/Caches/AudioUnitCache/ -
Once you find it, drag the two .cache files into the trash. Then empty the trash and restart Logic.
Sometimes (especially after updating Logic), it's helpful to move the affected plugins from your AU Folder to an external folder, then clear out the Cache Folder and restart Logic to rescan all other plugins. Quit Logic, drag the affected plugins back to your AU Folder, and restart Logic to rescan the affected plugins.
- Remove the license file from your hard drive. Don’t worry. This won’t cause you to lose an activation or change your deletion count. It will force the plugin to check in with our server and generate a new license file. To find your license file on macOS, go to the Finder, click on the "Go" menu, click on "Go to folder..." and then paste in this file path exactly as it appears below:
~/Library/Application Support/
