1. Visit remote file on an OSX system using /scp:hostname:/path/to/file
2. Modify buffer
3. Save
4. Note buffer-file-coding-system has updated to utf-8-mac (and (Mac) now
listed
in modeline).
5. Modify and Save again and the file line endings will be converted to
carriage returns.
I used git bisect to find commit
47fe7a5983a97c3e806e90340f3cd6ab3f0c49b2 introduced this behavior. Prior
to 47fe7a59 emacs would not modify the line endings of the file. I
believe utf-8-mac is only for Mac Classic files.

Well, I don't use macOS myself, neither locally nor on a remote
machine. So I hope you can help me to puzzle this out.

Well, IIRC, 47fe7a59 was just a refactoring of code. It introduced the
new macro tramp-skeleton-write-region in order to simplify Tramp's
different write-region implementations.
Hmm, you are speaking about "Mac Classic files". How could Tramp
determine, whether a remote machine uses this? These days, Tramp calls
"uname -sr". If the result string contains "Darwin", Tramp assumes macOS
on the remote side. Is there something else Tramp shall distinguish for
remote macOS'es?
Best regards, Michael.

Ping.
Could you pls provide the information? Otherwise, I don't know what I
could do.
Best regards, Michael.

More information was requested, but no response was given within a
month, so I'm closing this bug report. If progress can be made, please
respond to this email and we'll reopen the bug report.
