How do you download the installers for Big Sur and for older
versions of macOS? I've always had to go through the App Store to
download installers, and what it makes available for me is dependent
on the current OS version and hardware of my Mac. And half the time,
when I try to create a new VM using an old version's installer, the
installer process tells me "This installer has been damaged" and
refuses to continue. (This happens on installer copies that had
worked in the past. I assume it's some sort of certificate problem.)<br>
<br>
I ask because I've been trying to set up a VM-based build farm for
Octave and Octave.app (<a class="moz-txt-link-freetext" href="https://octave-app.org/">https://octave-app.org/</a>) and not having much
luck.<br>
<br>
Cheers,<br>
