Additional instructions for Mac

Important: the security mechanisms of newer MacOS systems do not allow running unsigned applications. Therefore, please follow the steps below the first time you run the launcher on MacOS.

Instructions

• Download the release to a location of your choice
• Open Finder and navigate to that location
• Unzip the file (usually double clicking on it is enough)
• Right click on the extracted ESLauncher2.app and select "Open"

• If you get presented with a dialogue with 2 options, click cancel and repeat above step

• Once you see the dialogue with 3 options, select "Open"

• The Launcher should open and from now on you can run it by just double-clicking on it.

Instructions for MacOS Sonoma, Sequoia and later: On the newest versions of MacOS (15.x 26.x+) you may see a different error message when trying to run the application. If you see a dialogue saying that the app is damaged and cannot be opened then you need to remove the MacOS quarantine flags:

• Take note of where you downloaded and extracted the application. You'll need to run a command against the unzipped .app
• Open the Terminal (use your Launchpad or press command-space on your keyboard to bring up Spotlight Search and start typing terminal.app)
• Once the Terminal opens, you'll need to change directory to your download location cd ~/Downloads
• Run this command xattr -d com.apple.quarantine ESLauncher2.app
• The command will not produce any output if it is successful. If you see an error "No such file" check your location
• Close the Terminal. You should now be able to run the launcher, or move it to a location of your choice using Finder

Please note: sometimes the launcher may open in the background. If you hear the music playing, check in the Dock, you should find it running there.
