However the drivers are not up-to-date and sometimes interfere with setting up an external GPU. Windows 10 can detect new graphics cards and install the drivers automatically. You can then install all software and games on an external hard drive.

Mac computers greatly benefit from these changes in Win10 If you experience issues, go with Win10 Windows 10 [ OS Build There are setup guides to install Windows on an external hard drive so that the internal PCIe flash storage can be preserved solely for macOS partition. Microsoft improved hot-plug detection and handling of Thunderbolt 3 devices in this version. Here are the recommended steps to set up an external GPU with a Thunderbolt 3 Mac and the reasons behind them. AMD graphics cards are likely to produce error The most reliable method is cold-plug. The majority of reported successes are with Nvidia graphics cards. Macs with four Thunderbolt 3 ports are slightly harder for eGPU implementation due to an extra Thunderbolt 3 controller and two more Thunderbolt 3 ports. If error 12 arises, disabling the connection to the non-essential components such as iSight camera or Ethernet controller would usually resolve it. Mac computers with only two Thunderbolt 3 ports would likely be able to negotiate enough resources for eGPU automagically. Large Memory allocation helps Windows handle a PCIe component such as an external graphics card without error Through many different user build guideswe have gathered not only setup procedures but also pre-compiled DSDT override files for those who need to patch the firmware of Late MacBook Pros. For the red team, get ready to go on an adventure called, error The name of the game is to allocate enough resources for the external graphics card to function in Windows 10 while not severely crippling other functionalities of the laptop. More than likely it will work without much trouble. If you decide to go with the green team, stop reading any further and go hot-plug the eGPU to your Mac.

On top of that is a pair of Thunderbolt 3 controllers to power four Thunderbolt 3 ports. Now that Apple officially supports external graphics cards in macOS since In order for automatic graphics switching to work, the crucial prerequisite is the Intel integrated graphics card.
