OSX / MacOS and the 4K Desktop

So, I’ve made the move to a 4K display for my Mac Pro.

That's a lotta dots

That’s a lotta dots

Well, a 4K TV, really, but that’s only because there aren’t any reasonably priced monitors.

There are definitely both pros and cons to this. I’ll lay out what I’ve discovered after the fold.

Fix OSX’s weird (mis-)mapping of the home and end keys

So, one of the things that drove me nuts about MacOS/OSX for years is Apple’s non-standard mapping of the home and end keyboard keys to start-of-document and end-of-document.

The non-standard key combinations CMD+ and CMD+ are used to perform BOL and EOL instead.

Here’s the problem: That is not how it’s been done on other platforms that long pre-date MacOS/OSX or even the Mac itself. I typically switch between multiple operating systems every day, and consequently, coming back to MacOS/OSX fouled up my typing/editing every time. So I went looking for a solution. I found one in Karabiner.

2009 Mac Pro with DVI and HDMI displays – restart problems

So I bought a new (old) Mac Pro; late 2009, 12/24 core, 64GB, NVIDIA GeForce GT 120 512 MB. It’s running macOS 10.12.3 Sierra. I hooked up one monitor to the HDMI port, and one to the DVI port. Seemed to work fine.

Until I rebooted the machine.

Then it refused to show the mouse pointer (Apple magic mouse), although It would warn of the mouse’s disconnect and reconnect if I powered the mouse up and down. Likewise, there was no response to the keyboard. It just sat there showing login options for me and a guest; it wouldn’t respond to anything at all I did with mouse or keyboard.

After trying power downs, pulling the plug for a while, pounding on the keyboard, powering the mouse up and down, I finally thought to pull a connection to a monitor. Specifically, the DVI-connected monitor. Immediately the mouse pointer showed up, and I was able to log in.

Up to this point, I had the machine set up so that the HDMI monitor was on the left, and was my home (boot screen) monitor. That’s the one you drag the menu bar to in the Prefs / Displays panel. But I noticed when the machine booted, it showed up on the DVI monitor first, then the HDMI monitor, and then it locked up.

So, still booted up after all this screwing around, I swapped monitor cables, then set the DVI monitor to be the home monitor, as the left monitor was now my DVI-connected monitor instead of my HDMI-connected monitor.

Now the machine restarts cleanly, or at least, it has a few times in a row.

So if you’re having this kind of problem, after the login screen shows, try pulling one or the other or both of the monitor cables to see if it will unlock the mess. And make sure the DVI monitor is your home monitor once you get things running again.
