A new version of Apple's dual boot software Boot Camp doesn't allow Macs older than 3 years to install Windows 10. Soon after the release of Windows 10 a new version of Boot Camp has been released by Apple making it possible run the latest version of Windows next to OS X. Boot Camp allows the user to select which OS to run on Apple hardware.
Apple has decided that Boot Camp won't support Windows 10 on Mac's older than 3 years. On the Apple website the company writes that Microsoft's latest operating system can only be installed on MacBook Pro, Macbook Air, iMac, Mac mini and Mac Pro computers that date from 2012 or later.
Computers from before that date won't be able to do a clean install of Windows 10 and also can't update from Windows 7 and Windows 8.1. The decision is strange at least, Windows 10 is known to run well on relative slow hardware. Much of Apple's hardware from before 2012 would easily run the operating system and these computers also still receive updates for OS X.
The Cupertino technology company has also decided that Mac Pro computers, equipped with high-end Intel Xeon CPUs and known to be the most powerful computers Apple offers, can only upgrade to Windows 10 if they are from late 2013 or later.
A Mac Pro from 2012 has a Quad-Core Intel Xeon CPU, at least 6GB of RAM, an ATI Radeon HD5770 with 1GB GDDR5 memory and either a 1GB SATA HDD or a 512GB SSD. These specs are more than enough to Windows 10, but nevertheless Apple doesn't support the OS on these systems.
It's unclear why Apple has decided that older models can't upgrade to Windows 10. A possible reason could be the Intel HD 3000 chip that is fitted in several Macs and Macbook Pro laptops and is no longer officially supported in Windows 10, although some users have found ways to unofficially make this happen. It's also possible that Apple is currently working on supporting more systems and will add more computers to the list the coming time.
Running Windows on Apple hardware is popular. Using Boot Camp the Apple can be used as any other PC but also still have the benefits of Mac OS X.
