I just did some work in the computer lab to make sure Keyshot is installed on the iMacs in the computer lab. It is on both the windows and mac installs for these machines. Rhino is also installed on both OS’s.
If you find one of these computers running windows and you want to use the Mac OS, you can restart the computer, hold the “alt” key as the screen goes black, then select “MacHD” from the options of two drives to boot from. The reverse situation works to (from Windows to Mac).
