There have been many questions and concerns about bottlenecking on eGPU implementations.
This is the beta version of the drivers and hopefully these glitches will be remedied by the time the Pascal drivers are finalized. Nvidia web drivers 378.05.05.05f01 are here, and they work with some visual glitches with Goalque’s automate-eGPU script to enable GTX 10 series eGPU support in macOS. This was a much longer delay than the previous seven-month wait for Maxwell drivers. All was forgiven though. Apmarked an 11-month wait for Pascal driver support in macOS since the GTX 1080 release on May 27, 2016. Everything was ready to go pending the web drivers from Nvidia. We prepped our Mantiz Venus Thunderbolt 3 external GPU enclosure with a GTX 1080 Ti then hooked it up to a Late 2016 15″ MacBook Pro. It subtly dropped the news Pascal drivers for macOS would arrive within a week to support this new GPU and a whole host of GTX 10 series graphics cards. Two days later, Nvidia announced a beast of a graphics card, the GTX Titan Xp. It vowed to completely redesign its next Mac Pro to make up with its core user base, the creative professionals. Apple apologized that its Late 2013 Mac Pro trashcan failed to meet users’ needs.
The first week of April has been insanely great for Mac users.
