SAS: SAS on the Mac

I have little experience with the Mac, and no experience with SAS on the Mac. Some of my students had trouble running SAS on the Mac. One of my students sent me this message. Saving it here just in case...

1. Exit the VM

2. Go to 'Terminal'

3. Type    sudo nvram boot-args=debug=0x10

4. Run the VM again and the bug will be fixed
