I promised I'd follow up with my KeyShot performance on my new 2019 MacBook Pro 16". The issue seems to be exacerbated when plugged into power strips (both mine and while traveling), so I'd say the issue is resolved with that caveat. No shutdowns, just painfully slow interactions OS-wide. So either my brick was faulty, or power strips aren't all made the same (which is a likely possibility).īr3ttj, to follow up on your question: when the battery drains, everything starts lagging and slowing down. One change this time around is that I'm plugged directly into the wall instead of using a power strip. No drop in power so far, and the system seems to be stable. So far today, I'm testing a scene on this laptop with a cycling animation using caustics at 100% usage in KeyShot.
To be safe, they replaced my power brick (at my insistence) since it was the only thing that they didn't test. According to them, the machine is working fine. The Apple store ran a bunch of diagnostics, both with a remote and local series of tests to tax the machine including overnight. To start with, this laptop isn't my primary computer (using a Threadripper workstation for most of my work), so this has only really been an issue while doing KeyShot training. Just a quick update from my end, got my laptop back last night.
The biggest question we get from customers is if the Powrbloc will can fully power the 16" MBP and I have to tell them "no" it won't just like the Apple supplied power adapter won't either. I've done lots of power tests on the MBPs for the past two years as I make a portable battery solution for the USB-C MBPs call the Powrbloc. Even plugged in to the 96W power adapter that Apple supplies, the machine will pull more power than the power adapter can supply and then will start to canabilize it's own battery to the point that it drains the battery as you experienced. No throttling, but getting a red battery symbol while plugged in is a PITA :/ Even using only a percentage of the available cores, my laptop loses power while running KeyShot (or testing through Intel power gadget) while plugged in.
