Fix thin fonts in Atom on OS X Mojave

Starting with OS X Sierra if you've noticed that the fonts are rather thin in Atom or other Electron based apps, the reason was that subpixel antialiasing is turned off in the OS defaults even though it's enabled globally through the Preferences Menu.

Thanks to Atom developer David Wilson who posted a fix on GitHub. The only way to fix the fonts is to enable it globally with the command line:

defaults write -g CGFontRenderingFontSmoothingDisabled -bool NO

And restart Atom or logout and login for the setting to take effect.

Anyone with some familiarity with unix filesystems will recognize the file permissions like -rw-r--r--. However, you will also notice a “+” and “@” symbol appearing to the right of the permission tables of some of the files. What are these? They are called extended file attributes.
