As is the case with most new operating system releases, there are initially a number of incompatibilities with commonly used applications and Yosemite is no exception. As a general rule, the Office of Information Technology (OIT) recommends most users should wait for a version update which would account for any initial bugs in the major release. Also, users should confirm compatibility of their commonly used applications before upgrading.
Early-adopters who are comfortable with the typical problems and potential application incompatibilities associated with new versions of operating systems and are willing to accept the risk of software that has only been minimally tested are advised to upgrade as they see fit. Note that there have been some occasional installation issues as described below.
While OS X 10.10 Yosemite adds some new features and has a different look and feel, it is designed to be familiar to users of previous OS releases and requires no training. For a full listing of new features, please visit the official Apple OS X Yosemite Page.
Installation: Testing of Yosemite conducted by OIT has found that some upgrades to Yosemite result in severe, but solvable installation problems. If you choose to upgrade and you run into problems, please bring your computer to an OIT Walk-In Center, contact Dedicated Desktop Support, or email the IT Service Center at email@example.com.
|Various Applications from the Mac App Store||
Some applications from the Mac App Store may not work with Yosemite. If you rely on any of these applications, it is a good idea to verify they will work with Yosemite before upgrading. To verify compatibility, visit the application’s page in the app store, visit the vendor’s website, or check a compatibility resource such as Roaring Apps.
|There have been some reports that the newest versions of these applications need to be installed.|
|FileMaker Pro Compatibility||There are some FileMaker 13 compatibility issues with Yosemite. If you rely on FileMaker Pro 13 for your business needs please see the vendor’s website: FileMaker Pro 13. Please Note: Earlier versions of FileMaker Pro have not been tested with Yosemite and are not supported by the vendor.|
|Windows Server 2012 REFS Compatibility Issue||
If your department is running a Windows 2012 File Server using volumes formatted with REFS instead of NTFS, Yosemite systems will be unable to upload files larger than 4GB (4090 MB). If you are a user of OIT Enterprise Storage you do not need to worry about this. Enterprise Storage uses the NTFS volume format.
Note: Testing of Yosemite conducted by OIT found that some upgrades fail, resulting in an endless restart loop. If this happens to you, please contact OIT for support.
