Apple recently released their newest operating system upgrade: version 11.0 (XI), also called Big Sur.
This operating system is not yet supported for University use and maybe incompatible with multiple University systems and applications.
Please do not upgrade your Mac OS to Big Sur until OU IT has announced it is safe to do so.
If you have already upgraded your Macintosh to Big Sur, you may be unable to use it with standard University systems, and IT will not be able to assist you with the device.
You may be able to access university resources via the MyDesk virtual desktop (http://mydesk.ou.edu).This has not yet been tested and confirmed.
The supported Apple operating systems at this time are 10.14 (Mojave) and 10.15 (Catalina).
