Macbook Pro 13inch retina 2015
Windows 8.1 was installed on BootCamp.
It was upgraded to Windows 10 and then the Apple Support Software (drivers) is not working.
- A USB flash drive (larger than 8GB) is formatted as FAT and Master Boot Record.
- Apple Support Software is downloaded through BootCamp Assistant. Use Action > download ... menu.
- After booting Windows 10, run setup.exe downloaded and saved in the USB flash drive.
- But there was a problem. The installation was stuck while installing RealTek drivers. I killed the child-process realtexsetup(32-bit) using task manager. (I guess that it is conflicting with the 64-bit Windows or H/W.) Then the rest installation was done flawlessly.
