Mac OS X Yosemite released


Mac OS X Yosemite (version 10.10, hereafter referred to as Yosemite) is the latest release of the Apple operating system for Macintosh workstations such as iMacs, MacBooks and Mac Pros. Released on October 16th, 2014, Apple lists many new features and improvements over the previous version at A pre-release version of Yosemite was tested for compatibility with a number of UVic applications and systems. 

New Macintosh hardware

If you are buying a new Macintosh it will come with Yosemite pre-installed. We recommend that you run Software Update to ensure you have any updates both for OS X but also for any Apple applications that may require an update to run under Yosemite.

Updating your Mac

If you have technical support through Desktop Support Services (DSS), in your department, or through the Computer Help Desk, please contact them to arrange your upgrade.

If you are planning to update your existing Mac to Yosemite yourself we recommend you follow this process:

It is especially important that you back up your Mac prior to upgrading.

Web browsers

Java plugin

If you are using an older version of Java, please note that your older version will be disabled if you upgrade to Yosemite.

Safari 8.0

The latest version of Safari does not have issue rendering and interacting with the UVic websites tested. My page, Webmail, Outlook Web Access, Moodle, FAST, and Banner all work as expected. Sign on to UVic works across and without issue. By default, the Java plugin is not enabled in Safari. When accessing a website that requires Java for the first time (such as Banner), you will be prompted to enable the Java plugin and reboot your browser.

Mozilla Firefox

Firefox has no issues and preforms typically with Yosemite. The current version 32.0 is not signed as an identified developer in Gatekeeper so you must explicitly allow the Firefox installer to run.

Productivity applications

Microsoft Office 2011

Microsoft Office 2011 for Mac does not appear to have any compatibility issues with Yosemite as long as it is updated to at least version 14.4.4. Documentation for configuring Outlook 2011 for use with UVic’s Microsoft Exchange Email and Calendaring system is available here.

Mac Mail, Calendar & Address Book

Please note that the following is provided for informational purposes only. University Systems does not support the use of Mac Mail, Calendar, and Address Book with the Microsoft Exchange Email and Calendaring system at UVic.

Mac Mail, Calendar and Contacts' compatibility with Microsoft Exchange has improved over previous versions of Mac OS. When starting Mac Mail for the first time it prompts for a name, email address and password. Once one enters their NetLink ID and password Mac Mail will automatically detect UVic's Exchange server. Once an exchange account is setup, Mac Contacts automatically has access to one's Exchange address books and the UVic global address list.

Although Mac Mail functions with the UVic Exchange servers, it does not implement all of the features of an Outlook client. Exchange server-side rule configuration, mail categories, and mailbox delegation are not fully supported and there are known mail synchronization issues.

Networking and printing


Wireless connectivity with the UVic, UVicStart and eduroam wireless networks was without issue. When connecting to UVic and eduroam a prompt opened asking for a username and password. Entering and an associated password worked as expected without requiring any certificate configuration.  Instructions to configure UVic wireless networks are available here.

Network storage

University storage resources work as expected with shares setup being identical to previous versions of Mac OS.


Printing requires appropriate PPD (Postscript Printer Definition) files that work in Yosemite and those may or may not be available from the printer manufacturer – check their website for updated drivers. You may be able to use the Generic Postscript driver.

Printing in PaperCut seems to work with the current 14.1 PaperCut workstation client. Page counting may be affected depending on the PPD used.

UVic applications

Filevault 2 Whole Disk Encryption

Filevault 2 successfully ran and encrypted the hard drive as expected in OS X 10.10 Yosemite.

VPN client

UVic uses a Cisco Systems virtual private network for securing remote connections to the university's network. The Cisco AnyConnect VPN client version 3.1.04074 installs without issue using the instructions available here. A test of connection stability was satisfactory.


OS X 10.10 Yosemite continues Apple's integration of iCloud service within the operating system.  Before using any iCloud features, University Systems recommends that you review the internet storage section of the secure your data page.  This section outlines relevant UVic policies and provincial legislation surrounding privacy and the use of cloud services.

University Systems recommends that faculty and staff refrain from using iCloud to store any university data as the privacy of this data can not be guaranteed. 

Other application compatibility

RoaringApps has created an application compatibility wiki for Mac OS X Yosemite here:

If you have concerns about a specific application, or a particular version of an application, you can visit RoaringApps to see if other users or the vendor have reported any issues with OS X Yosemite .

You may want to simply try the Mavericks or OS X 10.6-10.9 option on vendor websites when downloading application installers – it may work fine in Yosemite.
