There has been an Apple problem with the Apple Apps Store wherein downloading some softwares have not been working


This may also include downloading macOS 26 Tahoe


Alternative for the moment


Use the Terminal application


Use this command, suggest you copy and past the command into Terminal


 softwareupdate --list-full-installers


➡️. It should only search for Full Version of macOS this computer Qualifies to run ⬅️


Example >> list-full-installers


Finding available software


Software Update found the following full installers:


* Title: macOS Tahoe, Version: 26.0, Size: 16550645KiB, Build: 25A354


* Title: macOS Sequoia, Version: 15.7, Size: 15285579KiB, Build: 24G222


If Tahoe is listed, use the next Terminal command


softwareupdate --fetch-full-installer --full-installer-version 26.0


This will commence to download the Full Version of Tahoe 26.0


Note, the full version is about 17 GB in size


Once successfully dowloaded, check in the Applications Folder for a new application called " Install Tahoe app "
