It is unclear why Apple has chosen to drop support for Windows 7 on the Mac Pro, but it could be a sign that the company intends to discontinue support for the operating system in future Macs given its advanced age.
Apple’s Mac Pro only supports installations of Windows 8 or later with Boot Camp, according to an updated Apple Support document that lists versions of Windows compatible with the 2013 Mac Pro.
Boot Camp Assistant on the Mac Pro also specifies that it only includes support for Windows 8 or later, as evidenced in a screenshot from Twocanoes Software (via MacWindows) indicating that users are not able to install earlier versions of Windows. The 2013 Mac Pro is the first Mac that does not include support for Windows 7 with Boot Camp 5
The new Mac Pro 2013 is advertised to support up to 64GB of memory, and we understand that pro users running applications that place high demands on RAM have a need to meet and most likely exceed this threshold,” said Angus Wu, Director of Research and Development at Transcend. “For this reason, we have developed and fully tested higher density modules to give users the option of raising their Mac Pro system memory to the advertised 64GB right up to 128GB
Transcend has introduced new RAM updates for the 2013 Mac Pro, allowing users to bring the total amount of memory in their machines to 128 GB, double Apple and OWC’s maximum 64 GBs of RAM.
Transcend’s DDR3 RDIMMs are available in 16 and 32 GB modules to boost Apple’s 2013 Mac Pro machines to 64, 96, or 128 GB of memory, but its 1333 Mhz 32 GB modules run more slowly than the 16 GB 1866 Mhz memory modules it offers, along with those from OWC and Apple.
While the slower speed of the 32 GB modules may be an issue in certain situations, the possibility of bumping RAM to 128 GB will outweigh the speed loss for many power users.
