I recall when Apple released Catalina. So much software did not work for months. Every program I used back then that needed Native Instruments as a base just died completely. This was all down to Apple making changes between the Beta and final release. There are many sites out there that list software that is still not compatible with Big Sur, so it is unfair to blame PG Music for the problems. They always have got BiaB back up and running as soon as they possibly could.

While a few on the forum are throwing the toys out of the pram I for one appreciate the effort PG Music put in to BiaB. As Andrew said, Mac OS is a beautiful operating system. BiaB does pretty much everything I want it to right now, so I can wait for the few things that are causing headaches to be fixed.

Merry Christmas to one and all.
