Applite

If the Xcode Command Line Tools installation window doesn't appear, try installing it manually. To do this open the Terminal, located at /Applications/Utilities/Terminal.app, and paste this into it: xcode-select --install. A window will appear, follow the instructions. After the installation completes, reopen Applite and try the installation again.

If the installation fails you can try to install it manually. To do this, open the Terminal, located at /Applications/Utilities/Terminal.app, and paste this into it: /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)". At some point you will be prompted for your admin password. After the installation completes, reopen Applite. The Homebrew installation should be automatically detected, if not click I already have brew installed.

To add already installed apps to Applite, you must force install them. To do this, click on the little chevron next to the download button and select "Force Install". This will reinstall the application, you won't lose any associated settings or data.

This means that the brew executable couldn't be found, or it is damaged. You can try the following things to fix this:

1. Check brew path in preferences.

   Go into preferences and in the Brew Executable Path section, check if the correct path is selected. If you are not using your own brew installation then the first option (Applite's Installation) should be selected. If the selected path is correct there will be a green checkmark next to it. Relaunch the app for changes to take effect.

2. Reinstall homebrew

   If the path is correct, but it still doesn't work, it is likely that the brew installation got damaged in some way. If you are a more experienced user try running brew doctor on the brew executable that is not working. Otherwise, you can reinstall brew. In the sidebar go to the Manage Homebrew section and click Reinstall Homebrew. This will reinstall the Homebrew installation installed by Applite separately into ~/Library/Application Support/Applite/homebrew.

   Beware! After reinstalling all currently installed applications will be unlinked from Applite. They won't be deleted, but you won't be able to update and uninstall them through Applite.
