Having 90% of my 512 GB of storage taken up with System Data when running Ventura 13.3.1. I have 16 GB of RAM. I'm suspecting the issue is with Ventura since my iMac running on Monterey OS, 1TB of storage with 32 GB of memory. Anyone else having this problem and how do I return to Monterey?
MacBook Pro 15″, macOS 10.15
If the User is determined to Revert back to Monterey , the below should provide a method to achieve this >>
Scorched Earth Method
This method will WIPE ALL Data and there is No DATA Recovery - Period.
>> Only works on Intel Based Apple Computer <<
To perform this action will require booting from a Bootable Installer.
The Bootable Installer can Only be performed on an Apple Computer
This will have to be performed from a Qualifying Computer to run the version of macOS to be made on the Bootable Installer.
Example : Bootable Installer of Monterey would have to be done on a computer that Qualifies to run Monterey.
Notation: If the computer being used to perform this action is Too New or Too Old to qualify to run the version of macOS - this computer can not be used.
Alternative is, to gain access to a Qualifying Apple Computer from a family member, friend or associate.
