Hi, I'm still using Parallels Desktop 10 for Mac well. i just got a new mac today, so I want to activate license key on my new mac. However, I don't see any 'Sign out' button to deactivate on old mac with this version. Could you reset my activation status to move my license key? My account is the same email address as fourn account, and my key starts with GJMA**-***** Thank you!
