How do I get rid of Big Sur to revert back to a previous version of ios? I absolutely dispise Big Sur and what it has done to my system. My printer is no longer compatable, iphotos can't be used, I've lost a microsoft office package that costs 100's...

Yes TM and choose the Specific Date pre-11.3. Notation: is will only solve your issue for a short time as Apple will pester you to install 1.3 or whenever 11.4 is released.
Would it not be better to resolve the existing issue now?
Downgrade from macOS Big Sur to macOS Catalina or Earlier by:
Downgrading From Internet Recovery
Downgrading from Software Update
Hope this helps!
Try option + command + R
That is because Big Sur 11.3 replaced 11.2.3. The only way to get 11.2.3 would be if you save the Full Installer of it before 11.3 replaced it. That or a Bootable Clone of the drive when 11.2.3 was installed. Then, you might be able to re-clone it back after Erasing the Existing 11.3 Drive.
A Try Clean Install involves creating a USB Bootable Installer - in this case Big Sur. And, for sure it will be the last offered to the Public - so versions 11.3.1. The USB Installer Must be created on an Apple Computer that Qualifies for Big Sur. Once that is done, the process is straight forwards. Important matter here - ALL DATA on the target computer is removed and lost Forever. There is not " do overs ". Also, if the target computer has the T2 Chip for Touch ID - another step MUST be done to prepare this computer to be able to boot from and External Drive. Again one that is done:
1 - Shutdown the computer and disconnect all external Drives ( If Laptop - connect to charger )
2 - Connect the USB Installer and Restart the computer while holding the OPTION key
3 - This should present the Boot Manager with choices - choose USB Installer of Big Sur
4 - Several Option are presented and Choose Disk Utilities
5 - in Disk Utilities >> View >> View ALL attached Drives
6 - On Left side look for the Upper Most Drive ( Not volumes listed Below ) usually called Apple Media or Apple SSD
7 - That is the Drive to be Erased and Formatted as APFS and GUID Partition Map.
8 - That is done backup out of Disk Utilities
9 - Choose Install macOS and follow the prompts
10 - Computer will Automatically reboot several time
11 - if successful, the final reboot will present the Setup Assist of Big Sur
Dumb question...what is the best way to do a clean install? I found some websites but wasn't sure what the best way it was to wipe out the hard drive and then restore the OS (hoping to do it without using a USB drive since they are slow and unreliable....) I was going to try with 11.3 just to see if it works better with a clean install (then restore the data from Time Machine) and if it is still slow then I wanted to try to bring back 11.2.3.2(?)
Thank you so much for the step by step instructions! this will help me a lot! One question...I tried to do this today, but I have a Fusion drive so I wasn't sure on step 6 which one to choose. On my computer it said "Macintosh HD.." then it said "Macintosh HD - Data" below it. Should I choose "Macintosh HD" to erase? Above that it says "Container disk2" and above that it says "Fusion Drive" but I assume I wouldn't want to erase those two.
Have never ever worked with a Fusion Drive in this process I have outlined earlier. Not comfortable answering the question as it relates to Fusion Drive. If not done correctly from the start could be a Major Undertaking to put Right.
Perhaps the More Expert Contributor @dailabain, who posted earlier on this thread, might pick-up the gauntlet at this point and provide more details on Fusion Drive formatting and re-making the Fusion Drive a Fusion Drive again..
I've attempted this and several other steps found online, but it's not working. When I hit command + R, nothing happens. When I open my Time Machine there is also no action I can take. I'm lost.
How can I download the previous version of Big Sur (11.2.3?) I can't seem to find a place to download it.
You won't find it. The only version of a macOS (it's MacOS, not iOS by the way) available for download will be the latest version. So, that will be macOS version 11.3.
Would i be able to do that with a Time Machine backup? I assume not, but wasn't sure
I hope so and I appreciate all the help! It has been driving me nuts…the screensaver is messed up and it seems to be using a LOT of (virtual?) RAM
How to revert back to a previous version of macOS?
