Recently bought a new MacBook pro with OS Big Sur already on it which is not compatible with any of my DJ hardware, I'm struggling to find a way to downgrade from Big Sur to Catalina, iv tried most Youtube vids but there has been no previous back ups as this is a brand new MacBook, any help or advice would be grateful, thanks.
MacBook Pro 13″, macOS 10.13

The hardware on your Mac is made to use Big Sur as a minimum software requirement. This is set at the factory. You cannot go backwards. The correct solution is to tell the DJ software company to update their program (or use a different DJ program or an older Mac).
Apple has a webpage that will tell you specific information about your Mac via the serial number. If I find it I'll post it here so you can look it up. From what you're saying it sounds as if your particular Mac needs Big Sur as a minimum OS.

You will probably find you can boot into Internet Recovery Mode (Shift - Option (⌥) - Command (⌘) - R) on startup, erase the internal drive, and then install macOS from there. It will probably be 10.14 to 10.15 it loads. (And you can then upgrade from 10.14 to 10.15 if you like.
The all depends on which version that Mac model first shipped with.
Hi, iv tried that and it still takes me back to OS Big Sur, it is the MacBook Pro (13-inch 2020 four thunderbolt 3 ports)
surely there has to be a way to downgrade from this ? Or is it worth me taking it back to Apple for them to sort it ?
Odd. Your Mac should have originally run macOS 10.15.4 which means it's should be possible to downgrade (erase and reinstall) to that version.
I suspect you'll need to ask Apple how to force it to return to 10.15.x.
Only one thing - are you sure your DJ software (that would have presumably been provided with the DJ hardware) is compatible with 10.15.x? 10.15 and above cannot run 32-bit software.
You may end up needing to return your Mac for an older one, or see if there's a later version (64-bit) of its software).

That's interesting; thanks MyApple8MyPC. I didn't know that.
I'd mark this as 'helpful' but the option is greyed. Not sure why!
Wow, I'm very surprised by that, but all makes sense, the DJ software has been trying for the last few months (according to their webpage) thank you so much
