FYI.. Mac OS Catalina Security Update 2021-007 10.15.7 kills Amplitube 5.It will attempt to open then crash. At least on my 2012 MacMini. I verified this 3 times by reinstalling Catalina 10.15.7 then running Amp 5 successfully. Then after installing Security Update 2021-007 10.15.7 from Software Update it kills Amp 5.
Perhaps IK Multimedia can determine if this is an Apple or IK problem.
Thanks!
