GNOME Tracker Disable

Disabling GNOME Tracker and Other Info

GNOME's tracker is a CPU and privacy hog. There's a pretty good case as to why it's neither useful nor necessary here: http://lduros.net/posts/tracker-sucks-thanks-tracker/

After discovering it chowing 2 cores, I decided to go about disabling it.

Auto-starting VirtualBox VMs on MacOS High Sierra

Auto-starting VirtualBox VMs on MacOS High Sierra

Updated May 21/2018

There are lots of different how-tos out there for automatically launching VMs using VirtualBox on MacOS. Most of them focus on older versions of VirtualBox or old versions of MacOS.

Tested using MacOS High Sierra 10.13.4 running VirtualBox 5.2.12. The guest OS is Fedora 28.

Following the instructions on the VirtualBox website (https://www.virtualbox.org/manual/ch09.html#autostart), copy the Virtualbox autostart plist template file to your system's LaunchDaemons folder.
