CompuLab 4K Display Emulator (fit-Headless 4K)
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):

I’ve not tracked down the cause yet, but these seem to be related:
- The Mac OS X build of Atom IO
- WinBox v 3.4 WineBottle version from Winbox for Mac in an embedded Wine environment – Joshaven.com
- pbcopy / pbpaste that allow command-line copy/pasting
- 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.
- I didn’t have Mouse Keys turned on
- 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:

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.

You can use this package to install OS X on an empty partition, but perhaps more interestingly, you can also use it to upgrade existing OS X installations to a newer version of the OS X. There are many tools and workflows that support the installation of Apple packages; you can use these together with an OS X installation package to upgrade machines to the latest version of OS X.This is especially interesting when used with tools like Munki — you can automate the upgrade of a group of machines while still preserving user data, or offer an upgrade as a “Self-Service”-type option where a user can initiate an OS X upgrade themselves without needing to have administrative rights.
I will probably need this one day.

A while ago I had a “fzsftp could not be started” error using FileZilla on Mac OS X.
From the search results, it wasn’t exactly clear what I did wrong, as the “Show Package Contents” context menu showed “…/Contents/MacOS/fzsftp”
Then I remembered I got a bit confused with all the FileZilla updates coming out and renaming it to contain a version number (I do that with many applications so I can keep old versions allowing me to quickly revert to an older version if there are version compatibilities).
Renaming FileZilla.3.16.x.app back to FileZilla.app solved the issue: apparently FileZilla has a hardcoded dependency on exactly that name. I got there because of the hint about spaces in directories from this thread: fzsftp could not be started – FileZilla Forums
This was before Mac OS X El Capitan; with that version you have to set permissions correctly as well: fzsftp could not be started – Kruyswijk-ICT BV

I needed a second instance of Atom to run on a second monitor:
open -n /Applications/Atom.app
Or even shorter:
open -na Atom
I got there via: Launch & Run Multiple Instances of Any Application in Mac OS X
The reason is that searching for Mac OS X start second Atom instance does not reveal satisfactory results, as the tips in these links all fail:

In order to scan some local networks for unknown hosts (yes, on some sites you need to perform archeology), I needed the local IPv4 addresses, netmasks and CIDRs on my Mac running OS X.
Part of that is using ifconfig to get local inet information which however uses hexadecimal network masks and delivers no CIDRs.
SoI was a bit premature when I wrote about “This could be done by creating bash functions mask2cdr and cdr2mask, but that’s a bit too convoluted right now” in Getting the IP addresses of gmail MX servers – via Super User – dig isn’t enough.
netmask to CIDR and CIDR to netmask conversion
I need mask2cdr now, so lets start with these two bash functions and their aliases:

I always forget which OS X versions there are and which names they use.
So via: OS X – Wikipedia, the free encyclopedia, I made this list where the first item points to the table in the above article and each subsequent item to the individual article on the version. I tried to find EOL dates, but that’s hard despite the overview at Apple security updates – Apple Support:
None of this would be noteworthy if Apple, like Microsoft and a host of other major software vendors, clearly spelled out its support policies. But Apple doesn’t, leaving users to guess about when their operating systems will fall off support. | Computerworld
- Versions (the table with Version/Codename/Processor support/Application support/Kernel/Date announced/Release date/Most recent version)
–jeroen
PS: EOL dates are as of 20160403.
