Apple recently updated the existing MacBook product line, and Retina MacBook Pro and MacBook Air are all configured to be updated accordingly. In addition to being more robust, an updated MacBook product has a "feature" that seems to be overlooked: no longer supports the Boot Camp installation of Microsoft's WINDOWS7 system. Through the Apple Boot Camp support file, the new generation of MacBook products only supports Windows 8 or newer boot camp installations.
The first product to give up support for Windows7 Boot Camp installation was Apple's "trash bucket" Mac Pro in 2013.
That is, it is now possible to install Windows7 's newest device through Boot Camp, the MacBook Air and MacBook Pro that Apple launched in 2014. Of course, Boot Camp is not the only way for a MAC device to install a Windows system. If the user who buys a new MacBook product wants to install WINDOWS7, it can also be implemented by some third-party virtual software.
It is no surprise that Apple is abandoning its official support for the WINDOWS7 because the system is actually "old age". Microsoft first opened Windows7 downloads in 2009, and three years later launched Windows8 . However, although Windows7 is already 6 years old, it is still the most used Windows system.
