The install of H4 on my Mac Pro is intact: HALion Sonic purchased after installing C6, updated to v1.52, then purchased H4 when the upgrade from HS became available. The library is on a separate internal drive.
The issue is with the install on my MacBook Pro with the library on an external FW hd. I first noticed it when trying to load various pianos: Warm Grand, Dark Piano, etc
I reinstalled all (HS and H4) content onto the external drive. The user>Library>Application Support>Steinberg>Content>HALion>VST Sound folder has short cuts to all sounds on the external drive, with the following sounds locally installed (and also on the ext hd).
What do I do to fix this situation?
