Classification:Other Bug Reproducible:Always
mtm creates a plist without any name whatsoever on / which contains mtmUUID, file is 263 bytes in size and should at least be hidden (and maybe have a name?)

Steps to Reproduce:
disable mtm, delete the file, enable via tmutil enablelocal, boom, file is back

Expected Results:
a plist containing the mtmUUID is fine but it should be hidden on / and the file should have a name

Actual Results:
completely nameless file (ls lists „?“ as name or „“ depending on how you poke it). 263 bytes in size.

Happened on previous systems, too, in rare circumstances. Checked HFS, also with -Race, but no errors found. So it doesn’t seem to be HFS

Provide additional information, such as references to related problems, workarounds and relevant attachments.


On my machine, the file is named with a single byte with a value of 1. It can be referenced from bash using $'\x01'.
