Caution: Don’t Update Your Mac to macOS Sequoia Yet

Apple released macOS 15, Sequoia, on Monday, September 16, 2024. This is a major upgrade to the current Apple operating system, macOS 14 (Sonoma).

Information Technology Services (ITS) strongly advises that you DO NOT immediately install Sequoia for the following reasons:

  1. Compatibility testing: ITS is testing Sequoia’s compatibility with Denison systems and software. We have identified potential issues that may negatively affect key applications, including printing to network printers and logging into the machine from the lock screen.
  2. Timing matters: When considering a major operating system update, it’s best to wait until you aren’t depending on your computer to work as expected for daily tasks, especially during busy periods like the middle of the semester.

ITS continues to test macOS Sequoia with Denison systems and software. We will share an update on Sonoma’s compatibility as soon as we are able to do so.

Important Reminder: Before you update macOS on your computer, it is strongly recommended to back up your system and personal files prior to the update. In the rare event that there is a problem with the update process, it may be necessary to erase your computer’s hard drive, then install a fresh copy of the operating system and restore your personal files. To protect your important data, please adopt a recommended file storage location or backup approach.

If you have questions, please contact the ITS Service Desk at servicedesk@denison.edu or 740-587-6395.
