Okay. Maybe it's a difference between Linux and
macOOS. I downloaded the file from WInWorldPC.
The actual file came from someone named "Ricky" in
Germany. The file downloaded was "DEC VMS 5.5-2H4
(Jul 1993) [VAX] (ISO).7z" I ran it through
"TheUnarchiver" and it produced a folder with two
files. A txt file and "VMS 552h4 VAX.iso". I
tried burning that ISO file but then I get the
disk image is invalid error. <br>
<br>
I'll have to get a copy of SimH running on my Mac
and see it it can read the ISO. <br>

The file I got from WinWorldPC came as a
".7z" archive. and I unpacked it with
"TheUnarchiver". Does that match what you did?
The file I get from that always gets the "Could
not burn "VMS 552h4 VAX.iso". The disk image is
invalid." error from the Mac disk burn software.

Did you do something differently? <br>
