MacOS Sequoia 15.3.2 Update Released with Fixes for Bugs & Security Issues
MacOS Sequoia 15.3.2 has been released by Apple for Mac users running the Sequoia operating system.
The update includes important bug fixes and security patches, and Apple recommends installing the update on all eligible devices.
If your Mac is running macOS Ventura or macOS Sonoma, you will find an update to Safari 18.3.1 available instead of a full-fledged MacOS software update.
Separately, iPhone and iPad users will find iOS 18.3.2 and ipadOS 18.3.2 available as software updates, and Apple TV and Apple Vision Pro receive small updates as well.
How to Download & Install MacOS Sequoia 15.3.2 Update
Before anything else, you should backup your Mac using Time Machine or your backup method of choice.
- From the Apple menu, select “System Settings”
- Go to “General”, then go to “Software Update”
- You will see “macOS Sequoia 15.3.2” as available to download so click on “Update Now” to begin that process
Your Mac will require a reboot to finish installation, which might be a slight inconvenience but remember it’s also good to reboot occasionally to free up memory and as a modern MacOS maintenance task anyway.
For macOS Sonoma or MacOS Ventura, you’ll see an update for Safari 18.3.1 instead of a MacOS update.
