serial.log is disabled, enable, reproduce, share... And in general, please share a full system info bundle now, not just individual logs, like it says right above the post form here.
serial.log is still disabled, please enable it, reproduce, share a system info bundle. Don't unpack it, don't rezip it, don't add stuff, don't remove stuff, just share it exactly as produced by OctoPrint please.
Your fault is in not downloading a system info bundle but individual log files, and also serial.log not actually being enabled, otherwise there would be something more in serial.log than the message that says that it's not enabled.
Do you see how system info bundle turns blue and bold and underlined? It's a link to
It doesn't download to MacOS "packed"
Downloaded file is not zip or rar.
I can open it like normal file.
So can not upload here full of them, for example like this. (you can see all log files but without txt file)
Well, then whatever browser you have there is messing with things it shouldn't be messing with, because OctoPrint is sending that as a zip attachment with a fixed name, to be persisted as-is, and not with an arbitrary "please unpack me somewhere on the user's disk" note attached
In any case, serial.log is now enabled, but there's no printer communication in it. So please, with serial.log still enabled, connect to your printer, reproduce the issue until it happens, then share another bundle (maybe try right click & save as or whatever the equivalent is on Apple hardware).
