If you want to install Windows 8 on Apple’s MacBook via Boot Camp you might encounter a problem that you could not download the latest Windows support software or the download took very very long time and the download failed. It happened to me and many people when download the latest Windows software.
Luckily I found the solution for this after searching in Apple Support Communities website. Thanks to ‘rthed‘ who pointed us to solve this issue. Instead downloading it via Boot Camp Assistant, we can manually download it from Apple support download website. You can download the latest Windows support software for MacBook from here [554 MB zip file]. Unzip the downloaded file, go to the BootCamp folder and then run the setup.exe file
