Pepperdine IT Advisory: El Capitan OS 10.11 Upgrade

 
October 27, 2015

On Wednesday, September 30, 2015, Apple released Mac OS 10.11 (El Capitan). Pepperdine IT does not support El Capitan on university-owned machines at this time.Due to known challenges and incompatibilities with this release, Pepperdine IT recommends that you delay upgrading your Apple Macintosh computer to this new operating system. Known issues with El Capitan (10.11) include problems with email, Microsoft Office, whole disk encryption, device management, and several other applications.

Please remain on your current Mac OS version until Apple and other software vendors resolve issues with El Capitan.

Best Practices

To work and teach effectively, it's important to keep your system up-to-date and secure. At the same time, it's important to follow best practices before applying a major system upgrade to avoid issues.

Backup

Maintain current system backups of your computer and mobile devices to minimize data loss in the event of hard drive failure or problems after a major system upgrade.

"Update" Regularly

An update keeps your currently installed operating system up-to-date with security and performance fixes. Updates can occur several times a year, monthly, or even weekly in some cases, for example, updating your Mac OS Yosemite from 10.10.4 to 10.10.5. Please also use Pepperdine Browser Check and make sure our University Device Management Client is installed to keep other software secure.

Evaluate Major "Upgrades" Before Installing

Major system upgrades, like the El Capitan upgrade, happen infrequently, perhaps once a year, every other year, or longer. A major upgrade involves significant changes to a system and early adoption often leads to significant challenges. It can take weeks or months for software vendors to identify and resolve problems related to new operating systems. As stated above, please do not upgrade your university-owned Mac to El Capitan.

Whole Disk Encryption

If your university-owned workstation has whole disk encryption (WDE), wait for instruction from our Information Security Office before purchasing a new Mac computer or installing any major operating system upgrades.
