How to Choose the Best macOS Version for Disable OSX Major Updates
The best upgrade is not always the newest release; it is the newest release that keeps graphics, Wi-Fi, sleep, battery and daily apps reliable. Unsupported Macs depend on OpenCore Legacy Patcher root patches, and each macOS release changes drivers, security policy and graphics behaviour.
Quick Checks
- Backup current state: Save a copy of your working EFI and run a full system backup before changing settings.
- Identify hardware components: Note down your exact CPU, GPU, Wi-Fi card, and motherboard/laptop model.
- Ensure utility alignment: Keep OpenCore, OCLP, and ProperTree updated.
Fix Steps
- Create a rollback point: Make a Time Machine backup and keep a copy of your last working EFI folder before editing OpenCore, kexts or root patches.
- Match macOS to hardware age: 2011-2012 Macs often behave better on Monterey or Ventura; 2013-2017 Macs can usually test Sonoma or Sequoia with an SSD and enough RAM.
- Avoid risky releases for production: Treat macOS Tahoe or any newly unsupported path as experimental until OCLP support is explicit.
- Update OCLP first: Install the latest OpenCore Legacy Patcher, build/install OpenCore, then run root patches after macOS boots.
- Test the real workload: Check browser tabs, Office/Adobe, printing, sleep, Wi-Fi, Bluetooth and battery before calling the upgrade successful.
- Keep a downgrade path: Have a USB installer for the previous stable macOS before upgrading.
Verify It Worked
- The machine boots twice without manual intervention.
- Graphics acceleration and Wi-Fi work after root patches.
- The user apps that motivated the upgrade actually launch.
- Battery and thermals are acceptable for the intended workload.
Rollback
- Restore the previous macOS from Time Machine.
- Reinstall the older stable release with OCLP.
- Keep data on a separate backup before experimenting again.

Original Question: "Disable OSX Major Updates"
I have a Late 2011 MBP that is running Ventura 13.7.1 that is asking to be updated to Sequoia 15.1.1. Is there a way I can delete this notification and block the mac from going to a newer OS? I would still like security updates as they arrive which looks like they are but I tried Sequoia on this Mac and it was very slow so want it to never ask about that again if possible. Thanks!
