Apple does not support Downgrading to a previous version of macOS


This does not mean it is impossible, just not recommended


This downgrading is especially not suggested especially if the computer is an Apple Silicon M1. M2,M3 or M4 computer


The article relates to macOS 14 Sonoma , though the steps would be the same if going macOS 26 Tahoe to macOS ??
