Despite total feature and efficiency improvements for external GPUs, the new macOS Catalina is now failing to work precisely with clear mixtures of Mac and GPU card.A Sonnet eGPU with the Sapphire 580 in Apple’s possess developers’ kitApple has been gradually bettering how its Macs work with external graphics processing units, eGPUs, and in frequent macOS Catalina continues that effort. Nonetheless, with the liberate of Catalina, some users are finding that their Macs might perhaps perhaps well presumably now no longer force their eGPUs as expected.
The danger is to achieve with particular mixtures of Mac and eGPUs. From AppleInsider research, it seems to be that Radeon 570 and 580-primarily primarily based entirely eGPUs are having issues with the Mac mini most over and over affected.
Long-established issues reported by many users comprise an incapability as well up the Mac with a indicate linked to the eGPU. If the Mac will launch with the video display linked, it at as soon as restarts. Others represent their Macs freezing.
Our possess direct testing can verify that the issues are going down on a Sonnet eGPU with the Sapphire 570 card that turned into as soon as in Apple’s possess developer’s kit from two years ago.
Apple has been clear that no longer all eGPU playing cards and enclosures will work with all Macs —basically the most valuable omission being anything else made by Nvidia. Alternatively, Apple additionally publishes a list of successfully matched methods and that involves about a of the units at this time experiencing issues.One mixture of MacBook Pro and eGPU that Apple itself sells
One significant ingredient in that compatibility list is to achieve with the energy requirements of the eGPUs. Alternatively, energy does no longer seem like an danger here because the identical issues with the Polaris-primarily primarily based entirely Radeon 570 and Radeon 580 are reproducible within the Sonnet’s 350W and 650W variants.
Within the indicate time, it seems presumably that the danger is tied to drivers for Polaris AMD playing cards, nonetheless as but Apple has no longer commented.
