Q: Magic mouse 2 problem

Are you running El Capitan (OS X 10.11.4)?

Hello Hem85,

Your macbook cannot be running on iOS 9.3.1.   Perhaps you could find a moment to update your profile.   If you don't have El Capitan and you don't want to upgrade to it, you can still buy the old MM1 mouse ... but you need to specifically ask for it.   If it was bought from an Apple retail store you should take it back.   During the first 14 days (28 in the UK) you can return it without questions being asked, particularly if the assistant failed to ask if your machine was suitable.   It says quite clearly on the box that El Capitan 10.11 is required. 

Take a few moments to read this document.   Resetting the SMC looks the most likely task but you also should think through the interference element.   Be aware, you mmay have to reset some settings afterwards.

If your Apple wireless mouse, keyboard, or trackpad aren't working as expected - Apple Support

Don't forget to update your profile.   It is important if you ask questions here.

i have just 'installed the MM2, it wouldn't install with the lighting lead, only blue tooth and then only options i have within the 'mouse' on the setup up screen is 'click speed' & 'track speed' nothing else so the gesture can't be turned on, adjusted or anything because the option simply isn't there to do so.  SO I HAVENT A SCOOBY DOO WHAT TO DO
