    Installer for Catalina

    Is the Installer for Catalina still available? When I go to the App store, it doesn't show up in the Search. I downloaded it at one time, but it's not listed in my Purchased Apps. There are some links found on a Google search. When I click on them, they bring up Big Sur download. Thanks.

    Can anyone verify that the size in bytes of my "Install OS X" file is legitimate?

    Once I've purchased a new internal hard drive for my Mac Pro 4,1 to use to create a clone backup of the boot drive, and I'm satisfied that the cloning process has been successful, I want to upgrade my OS from Snow Leopard 10.6.8 to Mavericks 10.9.5.

    Three different InstallAssistants

    For the macOS installer app, under Contents/MacOS, there are three different InstallAssistant executables that seemingly look the same. Does anybody know the difference between InstallAssistant InstallAssistant_plain and InstallAssistant_springboard? Thanks!

One thing I'd like to try is modifying the installer itself, so that you can install with the default Leopard installer and use the Setup Assistant. However, I can't figure out how to do this, and the...

    I have El Capitan installed. However, I want to download the El Cap installer, make a bootable thumb drive and install it clean on a new SSD.

    So my external SSD broke and I lost a few files I was hours away from backing up. One of those files was my Safari 7.1.8 installer (the last version for Mavericks before they jumped to 9.x and changed some visual elements). The direct download links from Apple's servers are dead, as with every...
