Apple recently released its latest operating system for Macs called macOS 27 Golden Gate. macOS 27 Golden Gate introduces Siri AI powered by Apple Intelligence, and other improvements that make your Mac more responsive, secure, and reliable.
ITS supports this new OS and has verified that all supported applications are compatible.
Should you upgrade to macOS Golden Gate?
If you use any applications not provided by ITS that are critical to getting your work done, ensure they are compatible with macOS Golden Gate before you upgrade. You may need to look at the application’s website or contact their customer support team.
Tips for a smooth upgrade
Before you perform any OS upgrade, take these basic steps to protect your data and ensure that the upgrade runs smoothly:
- Back up your computer. ITS recommends you back up local files to OneDrive to ensure none of your data is lost in the process of upgrading. Microsoft OneDrive lets you store up to 2 TB of data, and share files with WCM colleagues in the cloud. OneDrive is the preferred method for storing WCM high-risk data, like PHI and PII. For help with OneDrive, read How to start using OneDrive on a Mac.
- Do you have enough disk storage space? macOS Golden Gate requires 13.51 GB of free disk space to install. Read How to see used and available storage on your Mac for details.
- Is Golden Gate compatible with your current device? Confirm you can update your Apple device by reviewing which devices are compatible with macOS 27.
- Before upgrading, save all your work and close all applications.
- Reserve time for the upgrade. Upgrades can often take some time to finish installation, so reserve a block of time during your day that won’t interfere with critical work. When you’re ready, download macOS 27 and start the installation process.
