Lion changed a default permissions setting on the /Library/Application Support folder to Read Only for admin, and when you install Powercore and it tries to wrap the plugins to RTAS using the FXPansion VST->RTAS wrapper it can’t write a core component that it needs in order to communicate between instances and pass audio around. This meant that the Powercore, as well as all the other FXpansion wrapped plugins no longer had any sound. They seem to wrap ok, launch ok, but silence…
First check that the system location /Library/Application Support is writeable from your admin user-account and that the file com.fxpansion.fxshared.bundle exists in that folder If that component doesn’t exist, or it can’t be created because the system permissions don’t allow for it, the wrapper won’t be able to start its audio stream. So… navigate to /Library/Application Support and hit cmd+I to see the properties. Click the padlock (and enter your password if prompted). Change the permissions from Read Only to Read & Write and you’re done.
Do a quick re-install of the Powercore software and you should be cooking. This should also work for any wrapped plugins with no audio – WOW filter and QuadraSID and of course my amazing VSS3 reverb and MasterX3 is back on the menu in ProTools HD 10!! Amazeballs.
