Download issues with the old version You must update to macOS 26.6 to download and use this app. How to download old version software?

The current version of macOS Tahoe is 26.7.1.

If you want to continue running macOS 26 Tahoe and keep that up to date, but skip the upgrade to Golden Gate for now, then to update to the latest version of Tahoe do the following:

• Open System Settings > General > Software Update.
• More info from Apple: Update macOS on Mac - Apple Support
• Click the (i) next to Other Updates under Also Available.
• Select the update(s) you want, which may include both macOS Tahoe and Safari updates.
• Click Update Now.

If you want specifically 26.6 and are comfortable in Terminal, then Open Terminal (find the app with Spotlight or in Applications > Utilities) and paste the following, then press return:

softwareupdate --list-full-installers

If macOS 26.6 appears in that list, you can download the full installer with:

softwareupdate --fetch-full-installer --full-installer-version 26.6
