Plugins not appearing in Logic Pro plugin list on M1 Apple Silicon mac computer

6/3/2021 Some Apogee customers have reported that one or more Apogee plugins do not appear on the drop-down list when instantiating a plugin. The plugin does appear in Logic Pro's Plug-In Manager list, is validated, with the "USE" checkbox selected, yet it doesn't appear when they try to use it on a track. This seems to happen most commonly with Clearmountain's Spaces, and only on M1-powered Apple Silicon Macs. Though we have sporadic reports of this happening with other Apogee plugins too such as the ECS Channel Strip, Pultec EQP-1A and MEQ-5, ModComp and ModEQ plugins, as well as the OPTO-3A. Apogee Engineers are investigating the cause of this, but in the meantime please try these steps: Completely uninstall the Apogee plugins.
