I recently ran bootcamp on my 2015 MacBook Pro and after successfully returning to my IOS I deleted the windows partition in the utility application. I also was running a beta version of Big Sur on my machine, and it won't let me update the computer now. I figured I could just run an update but I get a message that the "installer application is too old to be opened on this version of macOS". So I'm not sure what I can do to actually update to the actual Big Sur release, and fixing the deleting the partition thing. Do I have to totally wipe my computer and reboot everything? I also saw that when I restart my computer I think it starts in recovery mode and I have to hold the option key to manually select IOS for my usage. Which it works fine when I do log onto my profile but I know that I can't update the computer at all and I'd like to fix that. I appreciate anyone's help with this situation!
