Home C-117 Lab -- Windows Parallels


Some (12) of the iMac computers in C-117
are equipped with a program, Parallels.   Parallels creates a virtual machine (VM) which emulates (pretends to be) a PC running Windows 10.  This allows the iMac to run Windows software, like Reaper and Show Cue Systems.

Detailled below are the procedures to startup and shutdown a VM, and to connect the USB Audio Device to Windows. 

Failure to follow these procedures may render the iMac frustratingly unresponsive.


Power-up the iMac (if necessary) by pushing the Power Button on the rear left of the display.

Log into OS X (the iMac Operating System) as:
