[QUOTE="Rod, post: 1907548, member: 204485"] Going back to an earlier version of Mac OS can be tackled in two ways. The simplest was I can think of would be to Reinstall the OS the device shipped with from the using Shift - Option - ⌘ - R at boot. This is designed to install the original macOS the device shipped with. From there you can upgrade the OS by downloading the installer from [URL="https://support.apple.com/en-au/HT211683"]How to get old versions of macOS[/URL] The only catch with this is the installer can sometimes default to network recovery which can be problematic. Dropping out, can't connect etc. The second method is to download the installer for the macOS you choose eg. Mojave the last macOS that can run 32bit apps. Create a Bootable macOS Installer using a 3rd party app like Install Disk Creator onto a thumb drive. Boot your device from the thumb drive and use it's version of Disk Utility to erase your device's internal HD and install a mint version of Mojave (if you choose that OS). This will ensure there is no "rubbish' on your device and it will start up with the Setup Assistant allowing you to set all your own system preferences from scratch. [/QUOTE]
