adb command not found

Is adb installed? To check, run the following command in Terminal:

~/Library/Android/sdk/platform-tools/adb

If that prints output, skip these following install steps and go straight to the final Terminal command I list:

1. Launch Android Studio
2. Launch SDK Manager via Tools -> Android -> SDK Manager
3. Check Android SDK Platform-Tools

Run the following command on your Mac and restart your Terminal session:

echo export "PATH=~/Library/Android/sdk/platform-tools:$PATH" >> ~/.bash_profile

Note: If you've switched to zsh, the above command should use .zshenv rather than .bash_profile

In my case with Android Studio 1.1.0 path was this

/Users/<username>/Library/Android/sdk/platform-tools

Add the following to ~/.bash_profile

export PATH=~/Library/Android/sdk/tools:$PATH
export PATH=~/Library/Android/sdk/platform-tools:$PATH

Make sure adb is in your user's $PATH variable.

You can try to locate it with whereis and run it with ./adb
