Before you start with this procedure, please make sure that battery in vario is not discharged.

• Please download and run Skybean2 firmware update app, click here SkyBean2 update macOS.
• This app is not registered in Mac App Store, so macOS don't trust it and won't run.
• In the Finder, locate the app, don’t use Launchpad to do this. Launchpad doesn’t allow you to access the shortcut menu.
• Control-click the app icon, then choose Open from the shortcut menu.
• Click Open. Now, the app is saved as an exception to your security settings, and you can open it in the future by double-clicking it just as you can any registered app.
• Little black window will pop up with command "Connect SkyBea2", so please connect SkyBean2 vario to computer using micro USB cable and power it on (press yellow button on vario for 1 second).
• App will start to work and after several seconds it will finish when "Programming done!" will appear.
• SkyBean2 should wake up making start sequence sound, disconnect it and enjoy :)
