BootCamp, Parallels Support Statement
JMU Information Technology supports Mac OS X 10.7 Lion.
Boot Camp, VMFusion, Parallels, and dual-boot functionality are not supported.
JMU does not own a university-wide license for Lion, however, Information Technology (IT) will purchase upgrades in quantity to make the OS available to departments for the actual cost of $14.99 per copy.
To request a license and a Lion installation, fill out the “Setup and Installation Request for JMU-owned Computers, Printers, and Mobile Devices” form. After authenticating to the form, choose option 2 and select “New software on JMU-owned computer.” IT staff will contact you regarding scheduling the installation and to obtain your department's org code information to recover the cost of the license(s).
*Please note* As with all operating system installations, IT re-images the computer's hard drive before installing the new operating system. All applications and data are reloaded after imaging is complete. To ensure there are no data issues, we strongly recommend that you back up or copy all of your critical files to the network file storage prior to the scheduled Lion installation appointment.
