MacOS Sequoia 15.7.7 & MacOS Sonoma 14.8.7 Released

Apple has released MacOS Sequoia 15.7.7 and MacOS Sonoma 14.8.7 for users who are not running or interested in updating to MacOS Tahoe 26.5. The Sequoia and Sonoma updates include security patches only, and no other changes or features are along for the ride.
Curiously, the versioning is MacOS Sequoia 15.7.7, and MacOS Sonoma 14.8.7, but there was never any MacOS Sequoia 15.7.6 or MacOS Sonoma 14.8.6 update, suggesting that perhaps those were interim updates that got skipped for one reason or another. Whatever the case, if you are confused by the jump directly to .7 and skipping of .6 for Sequoia and Sonoma, you certainly aren’t alone.
Separately, Apple has also released a bevy of other software updates, including MacOS Tahoe 26.5, iOS 26.5, iPadOS 26.5, along with 26.5 updates for any other eligible Apple device, and other important security updates for older iPhone and iPad hardware. No matter what your Apple device is, you’ll want to check for updates as there’s probably one available.
How to Download & Install MacOS Sequoia 15.7.7 & MacOS Sonoma 14.8.7
It’s good practice to backup the Mac with Time Machine prior to starting a system software update:
- From the Apple menu, go to “System Settings”
- Go to “General” and then go to “Software Update”
- Ignore the MacOS Tahoe banner and look further down for the small “Also Available” section to find “Update Now” for MacOS Sequoia 15.7.7 or MacOS Sonoma 14.8.7

The Mac must complete installation by restarting the computer, so be prepared for that.
