What is the users tolerance for " Risk " ?


1 - Is this your Only computer and you would not be able to live without it for a fews days if the downgrade procedure goes wrong ?


2 - Does the user have access to another Apple computer, that currently is running macOS 15 / 26 , that could be used to Revive or Restore the computer  Firmware  ?


3 - Does the user have at least 2 -  no -  make that 3 backups from a time before the computer was upGraded to macOS 26 Tahoe ?


Have a 3-2-1 Rescue Plan in place and always current


3 Backups using 2 methods and 1 off site incase of natural disaster or un-natural disaster.


Each of the above should be done to a Dedicated Single Purposed External Drive 


Below link is intended to augment what TM Backup does

If the owner of this computer should answer NO  to any of the above questions


➡️. Then downgrading the computer Is Not Recommended ⬅️

Think twice or 3x time before considering this action


There are inherent " Risk " involved
