Bias FX2 won't open on Mac OS Big Sur

[max.mathern]

When I try to open Bias FX2 it says, that I don't have the access rights to open the program. My Mac is completely fine I just had a lovely 40 minute phone call with AppleSupport. I just downloaded the Bias FX2 again. Last time I had it downloaded, with the previous version of MacOS, it worked perfectly. How can I solve this problem?

Big Sur isn't supported yet by PG.
You can try downloading this beta version, some people are reporting it working with Big Sur.

In the future, check the audio apps websites to make sure they are compatible with the OS before upgrading. It can sometimes take months before some apps post updates to support the newest OS.
