Please hold off on updating to OS X 10.10 Yosemite

Apple released OS X 10.10 Yosemite as a free update on October 16th. Last week many of our students and staff experienced a rocky start with the new operating system, quite a few reporting that their Macs won’t even boot after the upgrade.

At this time ITS is recommending that community members NOT update to Yosemite. As with all new software, it is advisable to wait at least a month or two before upgrading to let the initial bugs and incompatibilities to be resolved.   In addition, ITS asks that staff and faculty NEVER upgrade the operating system on College-owned computers without first contacting the help desk.

If you have already upgraded to OS X 10.10, be aware that the following issues have been identified:

McAfee VirusScan 9.1.0 will not update definition files. ITS is working to make a newer version of VirusScan available to the community as quickly as possible.

Java-based applications will not run without a patch. Core Java applications include Banner, Crashplan, DropBox, and older versions of Adobe products. Patch available here:

Bluetooth and Wi-fi connectivity issues ranging from sudden slowness to dropping connections have been reported. We expect Apple to patch these services in a future update. In the meantime, bring your laptop to the help desk if you experience Bluetooth or Wi-fi issues.

Matlab R2012A through R2014A are not compatible with Yosemite. Mathworks has released a patch for these versions, available here: (you will need to log in with your Mathworks ID to access this page)

If you have any additional issues or questions please contact the Help Desk. Thank you for your understanding!
