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>
I'll have to get a copy of SimH running on my Mac and see it it
can read the ISO.

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.
<br>
<br>
<br>
Did you do something differently?

Thanks.
