Download old versions of macOS

[MikeMikeMike]

All of a sudden, we can't hit the old App Store versions Apple lists at https://support.apple.com/en-us/HT211683

Anyone else having issues? Our techs use the Big Sur downloader often.

@MikeMikeMike same here but you can have a look on this. https://macos.it-profs.de/downgrade-macos-monterey-without-usb-drive/

Yup, I haven't been able to download macOS Big Sur in several days. Glad I got 11.6.1 to our tech's USB drives just before this happened.

how about this command?

softwareupdate --fetch-full-installer --full-installer-version 11.6.1

[mking529]

I totally forgot about this. I just tried the command and it downloaded the installer! Great!

Interesting, I got error: update not available.

This has been a known issue going on with some endpoints not seeing 11.6.1. Try running the below command and then reboot the endpoint. It should then see it.

sudo /bin/launchctl kickstart -k system/com.apple.softwareupdated

Commandline does also not work for me in macOS but @mking529 you can use this url also:

I typically download the InstallAssistant.pkg files as they're already packaged by Apple. VPP has proved to be very unreliable for me. You can get the download links for Big Sur versions at https://mrmacintosh.com/macos-big-sur-full-installer-database-download-directly-from-apple/.
