How to Choose the Best macOS Version for MacOs Sequoia (15.6.1) sur Mac Pro 2013

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

1. 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.
2. 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.
3. Avoid risky releases for production: Treat macOS Tahoe or any newly unsupported path as experimental until OCLP support is explicit.
4. Update OCLP first: Install the latest OpenCore Legacy Patcher, build/install OpenCore, then run root patches after macOS boots.
5. Test the real workload: Check browser tabs, Office/Adobe, printing, sleep, Wi-Fi, Bluetooth and battery before calling the upgrade successful.
6. Keep a downgrade path: Have a USB installer for the previous stable macOS before upgrading.

Do Not Continue If

• Do not continue if: you do not have a working EFI backup, a Time Machine backup, or another bootable macOS installer.
• Stop and capture evidence: if the machine stops booting, take a photo of the last verbose line before changing more settings.

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.

Next Action

• Test now: reboot twice, reproduce the original problem, and confirm whether the same symptom returns.
• If it still fails: record the Mac model, macOS build, OpenCore or OCLP version, GPU, Wi-Fi/Bluetooth chipset, and the last visible error.
• Read next: use the related searches below for the nearest OpenCore or OCLP fix before making another change.

  I’ve been trying to install MacOs 15.4 but after patching the installer on the USB and reboot, I can’t find the EFI BOOT to continue with the installation, even if I try to run the installer directly it says that my Mac 6,1 is not compatible. What can I do?
