When the new Macs were launched with Apple Silicon, one of the disadvantages that existed is that sadly, these new processors were not compatible with eGPUs. That is, the owners of the new Macs could not add an external graphics to increase the power of the computer. In principle it should not be a big problem due to the potential of the M1 chip but it never hurts to help. a door to hope opens because in the future there could be compatibility.
An eGPU has been successfully communicated with a Mac with the new M1 processor. It’s just a matter of time and Apple
The new Mac models, that is, 13 ″ MacBook Pro, Mac mini and MacBook Air with Apple Silicon they could in the future be compatible with external eGPUs. At first it was seen that the incompatibility was absolute but this may change. The tests performed by Mac4Ever corroborated by AppleInsider’s own tests offer hope to eGPU owners. Although these are not officially compatible with the latest models with M1.
When connecting a Pro Display XDR to a eGPU Blackmagic inserted into a Thunderbolt 3 port, it was found that the graph was detected and it could work. The screen communicates with the MacBook Pro normally, with video playback.
The lack of support for external GPUs on Apple Silicon M1 Macs may only be temporary, as a connected eGPU is still detected, but does nothing. Additionally, AppleInsider has seen the same behavior on the Razer Core X, and the Sonnet eGFX Breakaway Box with a variety of cards, including the RX 590, Vega 64, and Radeon VII. The lack of drivers is the most obvious reason for the lack of support, but oddities in how Apple has implemented Thunderbolt or external PCI-E addressing can also be contributing factors to this incompatibility.
The solution It can be found in a macOS Big Sur update or a new version of the M1 chip. Even in a mixture of both. The fact is that Apple has in its hand that the compatibility remains in force in the future.
