02/20/19: Bootup Issue Affecting University-Managed Apple Computers
The following information pertains to anyone operating an Apple computer owned by Duquesne University.
During the week of February 4, 2019, CTS became aware of a condition preventing some Apple computers owned by Duquesne University from successfully booting up. CTS is continuing to refine the conditions and potential systems affected by this issue. It appears that the boot failure condition is associated with an Apple security update being applied to machines that have unique security permissions on the hard drive. At this time, we believe only Apple computers running Sierra (10.12.x) and High Sierra (10.13.x) are affected by this issue. CTS has been remediating Apple computers over the past two weeks, but believes there may be Apple computers still at risk of this issue. We believe that computers running Mojave (10.14.x) are not affected.
If you use a university-managed Apple computer, CTS suggests you take the following actions:
- If you are running Apple OSX 10.12.x or 10.13.x (Sierra or High Sierra), please contact the CTS Help Desk to create a ticket to review and remediate your system, if needed.
- CTS is currently blocking this update on many systems and suggests that Apple users do not manually apply updates to their systems at this time.
- If your Apple system fails to boot, please contact the CTS Help Desk at firstname.lastname@example.org or 412.396.4357 for assistance.
