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

Posted by jpluimers on 2017/08/28

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

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…..

Mac OS X – need to research this one day: How do I Check DHCP Lease info in terminal – via Ars Technica OpenForum

Posted by jpluimers on 2017/06/20

One day I need to research how to get the conversions right for this: How do I Check DHCP Lease info in terminal – Ars Technica OpenForum as I think that ipconfig getoption en0 lease_time gives me the value in a different format than date -r expects.

Also:

At T1 seconds (typically set to 0.5*lease_time) after the last successful renewal, the DHCP client attempts to renew it’s lease with the DHCP server that granted it’s current address via unicast. If unsuccessful, at T2 seconds (typically set to 0.875*lease_time) after the last renewal, the DHCP client attempts to rebind with any DHCP server via multicast.
