Plug-in Manager will not validate all plugins after new logic update
I installed the new release of Logic Pro. During the install process, it automatically validates all of the plug ins. Many plug ins were not able to be validated, including the Alchemy plugin which Apple boasts about as part of the new release. I tried to "reset and Rescan" but all I get is a bland screen and nothing happens. Has anyone else had this problem? Any suggestions? Thanks
