Open the store, search for the app you want, and click “Get” then “Download.”. Oct 06, 2020 I'm unable to download the installer.

Other macOS installation options
By default, macOS Recovery installs the latest macOS that was previously installed on your Mac.* You can get other macOS versions using one of these methods:
- On an Intel-based Mac, you can use Option-Command-R at startup to upgrade to the latest macOS that is compatible with your Mac. Exceptions:
- If macOS Sierra 10.12.4 or later was never previously installed, you will receive the macOS that came with your Mac, or the closest version still available.
- If your Mac has the Apple T2 Security Chip and you never installed a macOS update, you will receive the latest macOS that was installed on your Mac.
- On an Intel-based Mac that used macOS Sierra 10.12.4 or later previously, you can use Shift-Option-Command-R at startup to install the macOS that came with your Mac, or the closest version still available.
- Reinstall macOS from the App Store instead of using macOS Recovery. If you can't install the latest macOS, you may be able to install an earlier macOS.
- Create a bootable installerand then use it to install macOS on your Mac or another Mac.
