I have Windows 10 running perfectly on my I Mac (Boot Camp 3.3) with a magic mouse. Scrolling doesn’t work. Need solid, simple help from this community regarding new mouse driver and installation. I’m not a computer expert.

Thank you for posting in Microsoft Community. I understand your concern and I am glad to assist you.

Method 1: Update the Bootcamp software via the OS part of your laptop.

Go to Bootcamp assistant

Choose option that ask to update latest boot camp software for Win 7

Insert a blank USB drive

Once download is complete go back into Windows 10 and find the USB drive

Go to Bootcamp/drivers/Apple/Bluetooth and install all the files that show Bluetooth

Install the file called setup and let it install all drivers back on to MAC While you are still accessing Windows.

After doing this restart PC and check.

Method 2:

Find bootcamp version of your computer from here, and download it.. https://support.apple.com/en-am/HT204048

Open downloaded zip file.. and find folder called “AppleBluetoothBroadcom”(for me it was inside of “$WinPEDriver$” folder) extract it, and run the installer (called “DPInst.exe”).
