macOS Sequoia vs Sonoma Stability on Mac Pro 2010-2012
As Apple shifts its focus entirely to newer operating systems, macOS Sonoma updates are winding down. If you are considering upgrading your classic Mac Pro 2010-2012 (MacPro5,1) to macOS Sequoia using OCLP, here is what you need to know about real-world performance.
Real-World Performance and Requirements
- GPU Requirements: A Metal-compatible graphics card (like the AMD RX 580 or RX 5600 XT) is absolutely mandatory. Without a Metal GPU, Sequoia will be virtually unusable.
- AVX2 Instruction Set: Sequoia relies heavily on AVX2 instructions, which the Westmere/Nehalem CPUs in the MacPro5,1 lack. OCLP handles this via emulation, but it causes a slight CPU overhead.
- Wireless Cards: If you upgraded your Wi-Fi card to a Broadcom BCM94360, you will need to apply OCLP root patches for Wi-Fi and Bluetooth to function under Sequoia.
Recommended Upgrade Path
- Stay on Sonoma if Stability is Key: If your Mac Pro is a production machine, macOS Sonoma is currently the most stable and mature choice. It has fewer bugs and excellent performance.
- Upgrading to Sequoia: If you choose to upgrade, make sure you update OCLP to the latest version, rebuild your OpenCore configuration, and apply the post-install patches immediately after booting.
Original Question: "Apple's Sonoma updates"
 | As there is no Beta update showing today as available for Sonoma, but there is one now for the Golden Gate OS, I'm thinking this suggests that Apple updates are done for Sonoma, and wondering if anyone has had smooth sailing using Sequoia with a MacPro 2010-12? That would appear to be the last stop on the OCLP life extension train, but I don't want to go to the trouble to upgrade if my machine isn't a good fit (I know it's technically available, but am asking for real world affirmations/warning from actual users). Thanks for any feedback. [link] [comments] |
