The strange thing is, I couldn’t see any reference to it in Apple’s 10.12.2 release notes. I’m thinking that the fix is either experimental, unconfirmed, or the by-product of another fix. Either way, I’m just happy that this issue is resolved and I can now happily dock my MacBook, without having to turn it off and on again.
Tonight, I connected my MacBook to an external monitor via a new HooToo USB 3.1 Type-C Hub. This was the first time I’ve attempted to connect an external display to my MacBook and I’d very much like to be able to say that it just worked, but it really didn’t. As soon as I connected it to the monitor, the display started flickering, sliding in-and-out, and occasionally blanking-out completely.
For a few minutes, I wondered whether I had a flaky hub or HDMI cable, but after some googling I discovered that my MacBook was experiencing a known issue. Bummer.
Anyhow, after reading through a bunch of forum posts, I discovered that the fix is to turn the MacBook off and on again, I shit you not.
I’m frustrated and slightly annoyed with this experience. The MacBook was not a cheap device and I really didn’t expect it to exhibit a shoddy technical issue like this. I guess I’ll just have to wait patiently with anticipation in the hope that Apple can fix this via a software update.
