I have Parallels desktop installs and after upgrade to Big Sur I can't run it anymore because he need system extension and the system block it. When I go to Security & Privacy and Allow the sysext of Parallels to run it demend restart, and after restart it again don't let Parallels to run (in the list I have more system extensions like ATTO, Oracle and more that even after Allow (I try allow all and each separately) + restart the system don't let them run. Parallels is MUST for my work, what can I do to solve this?
