Apple shipped macOS Sequoia 15.7.3 some days ago, and you should install it if you stay on Sequoia. Apple says the release includes important security fixes.
At the same time, some Mac owners say the Software Update screen can steer you toward macOS Tahoe instead of the Sequoia 15.7.3 update. In user reports, the panel looks like you are about to install 15.7.3, but tapping the info icon shows the Tahoe upgrade selected in the details view.

What users say is happening on the update panel
People describe it as a confusing layout rather than a clear, single choice. You see a Sequoia 15.7.3 update, but the screen also promotes Tahoe, and the extra details can shift focus to the major upgrade.
That matters because an update and an upgrade are not the same thing. Sequoia 15.7.3 keeps you on the same major macOS version. Tahoe moves you to a new one, with bigger changes and a longer install path.
How to install 15.7.3 without accidentally starting a Tahoe upgrade
Use this checklist before you click anything that schedules an overnight install:
- Open System Settings and go to General, then Software Update.
- Look for the smaller macOS Sequoia 15.7.3 item on the page, not the Tahoe banner or headline option.
- Click the button that sits directly next to Sequoia 15.7.3. If you only see Tahoe actions, scroll and look again.
- If you open the details view, confirm it still shows Sequoia 15.7.3 before you approve the install.
If you manage Macs for family or work, tell people to slow down on this screen. One rushed click can turn a quick security update into a major OS upgrade.
How to stop macOS from nudging you toward major upgrades
Apple’s settings let you control automatic updates, but the labels can feel similar. Your goal is simple: allow security updates, but do not auto-start major upgrades.
Do this:
- Go to System Settings, then General, then Software Update.
- Open the automatic updates or advanced options.
- Turn off the option that installs or downloads major macOS upgrades automatically.
- Keep security updates enabled so you still get urgent fixes.
macOS 15.7.3 still matters, even if you ignore Tahoe
Apple’s own notes call 15.7.3 a security-focused update. Apple also published a dedicated security advisory for Sequoia 15.7.3 with CVE entries, which signals this is not a cosmetic patch.
Tahoe launched on September 15, 2025, and it brings a visible redesign plus new system features. Some people want that. Others prefer stability, app compatibility, or a predictable workflow.
If you plan to stay on Sequoia, install 15.7.3, but treat the Software Update screen like a contract. Read what it actually selected before you hit restart.
