The most recent OS update for Mac called Yosemite (version 10.10) has been causing problems for some users including frequent dropping from wireless networks and complications with Java.
ITS strongly recommends that, for now, Mac users refrain from upgrading their operating system to Yosemite (version 10.10). In the meantime, some of our software vendors are working on patches to help address problems affecting their programs and Apple is working on an updated release to help address the reported problems.
ITS staff will test the newer version when it is released and update the community.
Please consult your Desktop Support Specialist or the Student HelpDesk if you have questions about upgrading your Mac.
