Go to System Preferences

Open Security & Privacy settings

From General tab click on the Open Anyway button on the AXEL Go app that is listed under 

Allow apps downloaded from:’

After this, you can launch the app normally from the Applications folder

Enable Extension

If right-click menu – Pin and Share or Upload to Storage is not displayed even after install/re-install and successfully log in to AXEL Go app then check if the Pin and Share Extension is enabled under finder extensions

Go to System Preferences

Open Extensions

Click on Finder Extensions and see AXEL Go is enabled

Restart AXEL Go and Mac
