![]() ![]() ![]() They account for 16 total PCIe lanes directly off the CPU. The x4 PCI Express Controller connects to the right-side USB-C/Thunderbolt 3 ports (uses 4 PCIe lanes). The x8 PCI Express Controller connects to the left-side USB-C/Thunderbolt 3 ports (uses 4 PCIe lanes). The x16 PCI Express Controller connects to the Radeon Pro dGPU (uses 8 PCIe lanes). For example we used HWiNFO64 to check the arrangement of PCIe controllers and lane allocation on a Late 2016 15″ MacBook Pro (same as 2017 to 2019 model). Prior to setting up an external GPU, it’s a good idea to identify the routing of the PCIe connection over Thunderbolt 3 for your host Mac computer to learn about its capabilities. Therefore the ideal Boot Camp eGPU environment is an Intel iGPU-only Mac.Ģ018 15″ Macbook Pro + Radeon VII eGPU – Windows Graphics Settings Win10 1803+ provides manual graphics switching per app/game through Graphics Settings. In a Mac that has an AMD discrete graphics card and no functional iGPU, you would need Windor newer. AMD XConnect/Nvidia Optimus provides internal display loopback acceleration through the Intel iGPU with a Radeon/GeForce eGPU. In order for automatic graphics switching to work, the crucial prerequisite is the Intel integrated graphics card. Forum member Sky11 explained the three modes in Windows 10 (AMD XConnect, Nvidia Optimus, and Microsoft Hybrid Graphics) in this post. Let’s discuss graphics switching in Windows briefly. If you absolutely need to run Windows or Linux natively, you now have a reason to hold on to that Intel Mac–or buy a PC.Razer Core X Chroma + RX Vega 64 LC + MacBook Pro + 49″ and 5K Monitors Using virtualization software works for most users, but there is a performance compromise, though the compromise gets smaller and smaller as time goes by. Apple has continued work on the Intel version of Boot Camp-it was last updated in August with an update to the Precision Touchpad driver-but those updates are likely to end soon as Apple stops putting resources into Boot Camp as the percentage of Intel Macs in the installed base continues to shrink. ![]() Apple can now simply refer users to the Parallels setup whenever the Boot Camp conversation arises. Microsoft’s announcement dashes any hope that users had for a Boot Camp revival because it now gives Apple an official solution to point to. While Apple says the M-series Macs can run Windows for Arm, it’s not going out of its way to do it and there are no indications that development is happening. Since Microsoft’s Windows for Arm license has explicit details on the hardware it supports, presumably, Windows for Arm running natively via Boot Camp would be unauthorized.įor the small number of users who need to run a different operating system natively on a Mac, Boot Camp was a convenience, and users’ pleas to Apple to bring back the feature fell upon deaf ears. With Apple’s transition to the M1 processor in 2020, the company decided to not develop Boot Camp for the M-series Macs. 2006 also was the year that Apple switched from PowerPC processors to Intel, and since Windows runs on Intel silicon, Apple was able to provide the benefit of running Windows (as well as Linux) natively on Mac hardware–though Apple always reminded users that it did not provide support for Mac hardware running non-Mac operating systems.Īpple’s M-series chips use the Arm architecture, which is different from the x86 architecture in Intel processors, so the version of Windows that runs on Intel PCs will not work on M-series Macs. Parallels International The final nail in Boot Camp’s coffinīoot Camp became an official part of the Mac operating system in 2006 as part of Mac OS X Leopard. ![]() Microsoft has authorized Parallels as a solution for running Windows for Arm on an M-Series Mac. (When I asked Microsoft PR about unauthorized VMs, they referred me to the beforementioned support document and said that they have nothing further to share at this time.) The only other authorized option for running Windows on a Mac is to use Microsoft’s Windows 365 online service and run a Cloud PC. VMware Fusion, QEMU, and other virtual machines don’t offer a way to get Windows for Arm (though they can run it), and these VMs appear to be still unauthorized. Microsoft does not sell Windows for Arm as a standalone product, but you can download and install Windows 11 directly through Parallels. Microsoft’s announcement specifically names Parallels as an authorized solution. The authorization is a big deal because it means that in business environments, Parallels and Windows on Arm can be deployed, and users can get support if they run into problems. However, on Thursday Microsoft announced through a support document that Parallels Desktop 18 is now “authorized” to run Arm versions of Windows 11 Pro and Windows 11 Enterprise on M1 and M2 Macs. ![]()
