OpenCore lets you install Sequoia, but even on an early 2015 Retina 13”, it isn’t stable. The old MacBook, it’s a miracle it works at all. Downgrade to Ventura or Sonoma, and it will work fine. Unfortunately, the Legacy Patcher won’t let you install an earlier OS over a later one, so you have to back up your files, erase the disk and reinstall Monterey via Rescue Boot (Startup + Command R) first.
