How to choose a macOS version
Start with your exact Model Identifier, then compare the target macOS version against known hardware limitations. Newer macOS versions can provide newer app support, but they can also require more patching and expose hardware limits on older Macs.
- For the newest supported experience covered here, review Sequoia notes first.
- For many 2017 Intel Macs, review Sonoma notes and T1/T2 caveats.
- For 2013 to 2016-era Macs, review Ventura notes around AVX2, USB, wireless, and graphics.
- For older systems or lighter targets, review Monterey notes and root patch requirements.

About macOS Tahoe
Tahoe and macOS 26 questions are common, but the documentation used here only confirms support through macOS Sequoia 15.x. Treat Tahoe as a caution until OCLP release notes clearly announce support.
- Do not treat macOS 26 or Tahoe as supported until OCLP release notes say so.
- Check your exact Mac model before assuming a future macOS version will boot.
- If you rely on this Mac for daily work, wait for stable reports before upgrading.
Do not install a new macOS version on an unsupported Mac until OpenCore Legacy Patcher release notes confirm support for your model and target version.
