Stay on Sequoia

Block macOS Tahoe upgrade alerts with an auto-renewing deferral profile.

Defers the macOS Tahoe major upgrade by 90 days using a configuration profile. Minor Sequoia security patches are not deferred.

Auto-renews via LaunchAgent so you never have to think about it. When renewal is needed, it opens the profile in System Settings — you just click Install.

Install

git clone https://github.com/bjcoombs/stay-on-sequoia.git
cd stay-on-sequoia
chmod +x install.sh
./install.sh

System Settings will open — click on the profile and hit Install.

Optionally add this alias to your ~/.zshrc:

alias notahoe='~/Library/Scripts/renew-sequoia-deferral.sh'

What it installs

File	Purpose
~/Library/Scripts/renew-sequoia-deferral.sh	Renewal script
~/Library/Scripts/deferral-90days.mobileconfig	Profile template
~/Library/LaunchAgents/org.stayonsequoia.renew.plist	Auto-renewal LaunchAgent

How it works

• LaunchAgent runs at login and daily at 10am
• Checks if the profile is older than 83 days (7-day safety buffer before the 90-day expiry)
• If renewal is needed: opens the profile + System Settings + sends a notification
• You click Install — done for another 83 days
• macOS requires manual approval for profiles (no way around this without MDM)

Uninstall

chmod +x uninstall.sh
./uninstall.sh

Then remove the profile manually: System Settings → General → Device Management → Remove

Manual renewal

Run anytime:

notahoe
# or: ~/Library/Scripts/renew-sequoia-deferral.sh
