I use this add on for 2 computers a PC and a Mac Book, works great.
After installing the add on to a Mac desk top the desk top locked up.
The Mac would not reboot. After trying multiple methods for fixing issue related to Mac being unable to reboot the only option that worked was reformatting the drive and reinstalling the operating system.
