This situation was highlighted by Apple Insider, which famous that solely sure exterior GPUs (or eGPUs – graphics playing cards in exterior enclosures) have been affected. Reportedly it’s eGPUs that use Radeon 570 and 580 graphics playing cards that are operating into bother, with Mac mini customers seemingly struggling probably the most by the hands of this macOS Catalina gremlin.
Sadly the issues are fairly nasty ones and embrace of us reporting that their Macs are freezing, or not booting up when a show is linked to the eGPU (or the Mac may begin within the latter case, however then instantly restart).
It’s not clear what the foundation trigger could be, and Apple hasn’t been drawn to remark but, however the present most probably offender appears to be the drivers for AMD’s Polaris graphics playing cards (the Radeon 570 and 580 are each Polaris).
Evidently Vega-based GPUs aren’t hit by this situation. Moreover, it’s price noting that a few of the affected eGPUs are on Apple’s official listing of supported merchandise for appropriate Thunderbolt three enclosures, that are really useful for sure graphics playing cards
Certainly, Apple Insider asserts that it has examined a Sonnet eGPU with a Sapphire 570 graphics card inside, discovering points current – and that specific all-in-one combo is really useful by Apple.
Hopefully no matter bugs are messing issues round right here will probably be ironed out quickly sufficient.
Assist for exterior GPUs was launched again with macOS Excessive Sierra (10.13.four) as a neat option to beef up the facility of your MacBook (or certainly different Mac) by way of a Thunderbolt three port (with its chunky bandwidth).
Assist has been significantly refined since, with a great deal of optimization work carried out in Catalina and earlier than. Nonetheless, the dearth of official assist for Nvidia graphics playing cards stays a severe sticking level for a lot of of us.
Naturally, some bugs are to be anticipated within the new model of an working system, and macOS Catalina has additionally reportedly been inflicting emails to go lacking in some instances.
