Running your Mac Mini headless by faking a display for it (HDMI 1080p/4K or Thunderbolt VGA); similar for DVI

The MacMini is a bit dumb as it won’t enable the GPU when there is no display attached. Which means headless operation is cumbersome as display rendering is very slow.

There are a few tricks of which the off-the-shelve HDMI solutions work best.

You can buy them at Amazon:

Basically the trick to simulate a monitor with a dummy load works for other display connectors as well (most of them work fine with 75 ohm resistors, usually a bit lower or higher works just as well):

How-To: Automatically change your Mac’s display resolution when running specific apps [Video] – via: 9to5Mac

Yet another reason I love SwitchResX: : How-To: Automatically change your Mac’s display resolution when running specific apps [Video] | 9to5Mac

A few years ago, SwitchResX helped me switch my Mac machine to 1360×768 and 1888×1062 « The Wiert Corner – irregular stream of stuff

sleep wake – Macbook Air – battery drains while sleeping (but not when shut down) – via: Ask Different

Posted by jpluimers on 2017/08/07

I had the same issue as in sleep wake – Macbook Air – battery drains while sleeping (but not when shut down) – Ask Different which suddenly introduced itself in April 2016 after I had been running El Capitan (OS X 10.11) for a while.

The Mac didn’t have PowerNap active as I verified using How Power Nap works on your Mac – Apple Support

At first it looked like an SMC reset worked as explained by Reset the System Management Controller (SMC) on your Mac – Apple Support and mentioned in Mac Air loses 90% of battery overnight when in … | Apple Support Communities.

The Mac is indeed running Chrome, but I don’t like to turn that off before sleeping.

Executing pmset -g would show hibernatemode 3.

So I opted for the hibernate option as mentioned in the first link:

sudo pmset -a hibernatemode 25

This will take a bit longer to restore the memory from hibernate state, but saves a lot of frustration.

The strange case of some applications not being able to copy/paste on the Mac OS X clipboard

Posted by jpluimers on 2017/07/19

I’ve not tracked down the cause yet, but these seem to be related:

  1. The Mac OS X build of Atom IO
  2. WinBox v 3.4 WineBottle version from Winbox for Mac in an embedded Wine environment – Joshaven.com
  3. pbcopy / pbpaste that allow command-line copy/pasting
  4. none of these being able to copy/paste any more and return error level 1 like terminal – pbcopy exits code 1, no error message – Ask Different but not even running tmux or screen which means this solution does not apply: ChrisJohnsen/tmux-MacOSX-pasteboard: Notes and workarounds for accessing the Mac OS X pasteboard in tmux sessions.
  5. I didn’t have Mouse Keys turned on
  6. Other applications (Chrome, FireFox, TextEdit, Finder, etc) still being able to copy/paste between each other

I’ve “fixed” 4. by doing this as recommended at osx – Copy and Cut sometimes don’t work – Ask Different:

launchctl list | grep com.apple.pboard

If the pboard daemon is running, then stop and start it. If it’s not running, start it:

launchctl stop com.apple.pboard
launchctl start com.apple.pboard

Now 4. works again if I restart each application, 6. still works, but these applications still cannot copy/paste to 1. 2. and 3.

What does work is a full reboot, but that takes a while (especially Chrome re-loading lots of Windows: I need to get more organised here).

It might be that I need to restart each application in 6.

Grrr…..
