My point was that a classic Mac user (read: from the 80s) would know how silly it would be to hem and haw over "Mac OS" (with a space) vs. "OS X" vs. "macOS", and thus, arguing capitalisation and spacing semantics (esp. when most of those emulators were probably from 2016, which during late of was when Apple marketing decided to switch from "OS X" to "macOS") was sad -- hence, sad Mac. If a person says "OS X" we know what they mean, if they say "MacOS" when talking about present-day software/Macs, we know what they mean; the pedantry isn't necessary but is funny (to me) since Apple is effectively going back to the original name (sans a space and capitalisation -- again, who cares?) as their System 1 through 9 software. ;-)
Super off-topic as mentioned: as for the crash codes shown: it depends on the model of ("classic") Mac, and *when* the crash/issue happens. I remember that 0x0F meant an exception error, and that the remaining part of the code (or the code on the 2nd line) represented a detail/state code that was more indicative. I had to do some digging, but
here you go. From that you should be able to discern that the Mac depicted is probably a Mac SE or Mac II indicating code 0x0000000F (exception error), subcode 0x0000000D (SCC failure; SCC = Zilog SIO (serial controller) used for controlling the serial ports). SCC isn't a new term to me, since the smae chip is on the IIGS (an 8530) -- and I sure hope I'd be familiar with it, considering
I wrote a IIGS CDA back in the early 90s called QuickPort II that allowed setting the serial port >19200bps, haha. :D
