What this question is not about

  1. Downloading macOS Developer Beta Access Utility
  2. Downloading a stable/GM release of macOS
  3. Downloading the .0 release of a new macOS beta (when it is released at WWDC)

Say I want to install a macOS beta point update to a Mac that is never online (say if I had a lake house Mac or something). How would I download a .dmg or something so that I could install it on another machine. The macOS Developer Beta Access Utility just starts the update process on the machine it runs on.

  • Found this python script mentioned in this thread - derflounder.wordpress.com/2018/02/27/…. This is the thread - reddit.com/r/osx/comments/932rgz/…. – slm Apr 15 at 15:09
  • There's this repo as well - github.com/munki/macadmin-scripts. – slm Apr 15 at 15:10
  • @slm Thanks. I haven't seen this before. Unfortunately the script doesn't currently give options for Mojave beta. This is what it outputs: 1 041-47723 10.14.4 18E2034 2019-03-25 macOS Mojave 2 091-95155 10.13.6 17G66 2019-01-08 macOS High Sierra 3 041-49229 10.14.4 18E226 2019-03-25 macOS Mojave – Steve Moser Apr 15 at 15:19
  • You probably have to change the --catalogurl to get at the betas. – slm Apr 15 at 15:23

    @slm Thanks, though it seems the osxdaily links are for not for the beta. I tried clear catalog too. – Steve Moser Apr 15 at 17:26

I'm sorry, you're question is still a bit confusing to me, but I'll take a stab at it:

Your best bet is probably to comb through the listings you'll find in the Software Update catalogs found in Seeding.framework. That is:
plutil -p /System/Library/PrivateFrameworks/Seeding.framework/Resources/SeedCatalogs.plist, and (since we're talking Dev builds), probably
curl -Ls https://swscan.apple.com/content/catalogs/others/index-10.14seed-10.14-10.13-10.12-10.11-10.10-10.9-mountainlion-lion-snowleopard-leopard.merged-1.sucatalog | plutil -p.

You'll then need to grep around for the packages you're looking for; they're not always named the same, but if you grep for macOSUpd, you'll find the necessary packages, i.e., http://swcdn.apple.com/content/downloads/46/21/041-19988/kct9qwin7h5nz0awoc9ke03m2s7qp4q7t9/macOSUpd10.14.2ForSeed.pkg.

Does that help?

  • Thanks, that does help. For some reason the utilities I was using wasn't able to create an installer from that file but searching through it does provide a beta combo update package file download link. – Steve Moser Apr 19 at 15:08
