I blogged about changing the CatalogURL back in the days and nowadays websites are no longer shy to mention what you need to do in order to get a Beta or Developer seed without first having to sign up for Apple programs. All you need to do is change the App Store URL – the so called CatalogURL – to one of the following with sudo /usr/sbin/softwareupdate --set-catalog

Developer Program Members

Beta Program Members

Regular Updates


You can show/verify the CatalogURL with the following terminal command:

sudo defaults read /Library/Preferences/ CatalogURL

Et voilà.

  1. hmm. not working here. this catalog change enables softwareupdate to download and install developer-seed OS updates without enrolling in the dev program, right?

    so i sudo’d the catalog change to the developer url, and then listed available updates – response was none available (from both command line and app store gui).

    then tried restarting mac, still no dice. ran sudo softwareupdate -clear-catalog command to reset catalog url, then tried both dev and beta urls, still “no updates available”.

    i’m on current yosemite 10.10.5 – am i missing something?

  2. Hey man I just noticed you had missed one (-) from your: sudo /usr/sbin/softwareupdate –set-catalog so i changed it to — set-catalog 🙂 then it worked thanks for your amazing work and blog, hope you doing well take care 🙂
