Are Big Sur installers working?

[craig65535]

I have a 2008 (Intel) Mac Mini running macOS 11.2.3.

$ sudo python installinstallmacos.py

Two observations:

• Install macOS Big Sur.app/Contents/SharedSupport/SharedSupport.dmg does not exist, but seems to be expected by postinstall.zsh.
• The No server metadata for 071-05432 warning for 11.2.1 and the other BigSur versions.

@blacktop This happens with an empty content subdir, and does not appear to have anything to do with the downloads themselves.

[craig65535]

Building a Catalina installer (e.g. 001-68446 10.15.7 19H15 2020-11-11 macOS Catalina) seems to work. So, I think this issue is isolated to building a Big Sur installer.

[gregneagle]

I’ve built Big Sur installers for each release without issue. Haven’t tried in the last week or so.

[craig65535]

@gregneagle I've built them before, too, so maybe something changed.

Taking a look at my install.log...

The .dist file that is being installed contains a reference to InstallAssistant.pkg. That pkg file contains Scripts/postinstall.zsh which calls Scripts/postinstall_actions/link_shared_support.zsh. When run, the latter tries to find SharedSupport.dmg in the nonsense path /private/tmp/dmg.y9IuqGApplications/Install macOS Big Sur.app/Contents/SharedSupport/SharedSupport.dmg. Note the lack of / before Applications.

Maybe the script in InstallAssistant.pkg is now broken and will only work when the target is / and not something like /private/tmp/dmg.XXXXXX?

[craig65535]

Could also be different behaviour with /usr/sbin/installer on 11.2.3.

Interesting, I seem to recall a block of code in your installer where you rename the /private/tmp/dmg.y9IuqGApplications to /private/tmp/dmg.y9IuqG/Applications here - https://github.com/munki/macadmin-scripts/blob/main/installinstallmacos.py#L228

So maybe Apple got lazy and now just tries to use the "mistake" /private/tmp/dmg.y9IuqGApplications instead of fixing it?

[craig65535]

@blacktop It definitely seems to be a related issue. In this case the script is half-correct - writing to the correct path, but then reading from the wrong one.

[craig65535]

I found something interesting: running the script from a different directory, e.g. ~/devel/macadmin-scripts, works. It fails when running from ~/Downloads, e.g. ~/Downloads/macadmin-scripts-main.

I noticed the same for ~/Documents. I think this is a SIP thing?

It looks like the script will need to be be updated to refuse to run from certain protected folders.

[blacktop]

Whoa! that's very interesting. I've also been running out of my Downloads folder, I'll try again in a different one

[gregneagle]

Or you could read the Read Me :-)

[craig65535]

@gregneagle I noticed that there was a check for the current directory, but it wasn't working for me (my script was in a subdir under Downloads, not Downloads itself). #87 should address that, and also make the warning more noticeable to users.
