Screenshot features in Mac OS X and MacOS

10.13 High Sierra and earlier : Use key shortcuts (see below) or Grab.app (see here)

11.14 Mojave and after: Snapshot.app (more info here):

  • Similar to Grab but after you’ve taken the snapshot it allows you to annotate/markup the screenshot, and then you can either copy and paste from there or save as a file.
  • Additionally in Screenshot, it remembers the position on screen of an area screenshot so you can easily take repeated screenshots from the same portion of your screen.

Key shortcuts in all Mac OS X / MacOS versions (see here)

Shift + Cmd + 3 : captures whole screen

Shift + Cmd + 4 : starts a region screenshot, select a region of the screen

  • before 10.14 Mojave, saves a .png to your desktop
  • 10.14 Mojave and after – opens screenshot in the Screenshot editor app

Mac Docker 1.12.0-rc3-beta18 native client and insecure registry

A while back I set up a local Docker Registry to share images between different machines, and configured it as an ‘insecure registry’ since it’s just for testing. With the latest native Docker engine for Mac OS, I was having difficulty pushing to the Registry, it was just fail with a cryptic message:

$ docker push 192.168.1.66:5000/rpi-mongodb

The push refers to a repository [192.168.1.66:5000/rpi-mongodb]

Get https://192.168.1.66:5000/v1/_ping: http: server gave HTTP response to HTTPS client

I noticed in the Docker menu from the menu bar that there’s a Insecure Registries section under Preferences, Advanced Options. Adding the IP and port of my Registry there fixed my problem, now I can push:

$ docker push 192.168.1.66:5000/rpi-mongodb:latest

The push refers to a repository [192.168.1.66:5000/rpi-mongodb]

Mac OS X Yosemite

Ars Technica has a fantastically detailed review (25 pages) of the latest OS X release, Yosemite. I’m browsing though the article as my 5.1GB download is slowly coming across the tubes. Maybe sometime tonight it will have completed and I’ll be ready to install 🙂

In the meantime, I’m wondering whether I like the ‘flat’ UI look, and prefer the 3d style icons and shadows in my dock, but I’m sure I’ll get used to it.
