Is there a way to revert to OSX 12.x from 13.2?

A recent upgrade from OSX 12.x to 13.2 has truly messed up my M1 Mac resulting in being unable to have any machine (iMac or 2012 MBP) connect to it, share files, run Automator over WiFi same network.

After spending days, checking privileges, deleting and re-adding accounts, nothing works. M1 to iMac works but iMac to M1 or MBP to M1 doesn't.

If there's any way to reset to the OS that came with my Apple M1, thank you for letting me know.

Here’s the DVD-analog full-manual path:

… How to download macOS - Apple Support

… Create a bootable installer for macOS - Apple Support

Download Monterey, build a USB installer, boot that, and erase, and install.

There’s no good path to downgrade short of restoring a pre-upgrade backup, and the files and settings in use from a newer version may not or will not revert and work on earlier versions. Either there’s a backup, or the process is manual and tedious and mostly involving copying over version-independent documents and such.

And where would one get the software? DVD? I really don't know what else to try...

I did know about the DVDs, but at least then we could recover easily at home, irrespective of bandwidth...

Will that provide the original software that came with the MBP or the latest software available for it?

Appreciate the pointer, thank you

Thank you. Just wonder what or why this happened.

Without poking around in the carcass, no good answer. Corruptions, hardware failures, weird add-on apps, add-on cleaner apps or add-on anti-malware apps, various possibilities exist. Including bugs in Ventura effecting whatever you’re doing here. There’s a running discussion of the Ventura SMB server elsewhere around here, too.

Some really weird symptoms like:

M1 will not reply to ICMP messages like "ping" even though stealth mode is disabled. Yet, I can ssh to it from iMac for example.

Home directory (even though privileges checked with Disk Util) when set to RW doesn't allow you to view any file structure on M1 irrespective of remote user. Setting it to R only does allows you to see the top level directory (apply to sub directories has been selected to folders beneath).

Automator no longer works from iMac to M1 as it can't Connect to Server. AAMOF it can't even resolve a get specificied server on itself, meaning from M1 issue a Get Specified Server as smb://192.168.122:445/Desktop (it's a fixed IP)

OTOH M1 can access iMac and all subdirectories with remote user's home directory set to RW and Go to Network or Server.

This since upgrade to OSX 13. Thank you for your and BDAqua's help!
