Parallels: copy-paste not working from Mac to Fedora VM

This one is weird but worked for me.

You should set SELinux as permissive, reboot, and set it back to enforcing

Edit /etc/selinux/config and change to

SELINUX=permissive

Reboot

Set backup to enforcing

SELINUX=enforcing

Reboot again.

Now copy-paste works for me. Let me know if it works for you :-)
