Which brings me to the next point, with cryptocurrency and any other various reasons to spike the prices for high-end GPUs, Apple’s selection of few high-end GPU made the eGPU experience much more vulnerable to outside force than before. The metal dev kit is now priced at $599, but RX 580, which is included in the kit, is now priced around $400-600. And who is to say the price will ever come down?
On Sierra, however, you can easily use any other eGPUs with a code provided by goalque. The development is ceased, but it’s still doable. On High Sierra, we are yet to find out if and when eGPU support is ever guaranteed. I can only hope, –considering what is now available– that the price of those 4 GPUs to drop by the time High Sierra is officially released.
Next up is obviously APFS. I have finally managed to install APFS on 1TB fusion drive without getting constant kernel panic. It is a long waited bug fix, but I still wouldn’t recommend installing second beta on any main workstation. Perhaps third beta would be more reliable.
