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 :-)
