Missing Disk Options When Installing OS X

diagnosis: hard drive crash, and removed partition.

Select the hard drive in Disk Utility on the left; on the right, select the Partiton tab; under Partition Layout, if the box is all gray (meaning there is no partition), then press the + button at the bottom; then hit Apply.

Check Device Serial Port on Mac

You can find your Arduino via Terminal with

 ls /dev/tty.*

then you can read that serial port using the screen command, like this

screen /dev/tty.[yourSerialPortName] [yourBaudRate]

for example:

screen /dev/tty.usbserial-A6004byf 9600

source: http://stackoverflow.com/questions/12254378/how-to-find-the-serial-port-number-on-mac-os-x

Free a Busy TTY Device

From terminal, run:

lsof | grep usbserial

If the port is in use, you will get a response like this (otherwise it will return nothing):

screen    27127 Sefi    5u     CHR               18,0        0t0       605 /dev/tty.usbserial

Note the session number. In my case, it's 27127. Then run:

screen -x 27127 (obviously use your session number from the grep)

It will return you to your previous screen session. Then use ctr-A ctr-\ to close it properly (will ask you to confirm).

Disable Leap Motion App on Startup

You will find a line item

com.leapmotion.Leap-Motion.plist

Library/LaunchAgents

Just rename from .plist to .bak - incase you would like to auto startup again.

I believe Leap Motion chose to use LaunchAgent rather than 'Login Items' is because they couldn't get it to startup all the time.

Google Chrome Helper Process

The quick story is that Google Chrome Helper isn’t really the problem. It tends to go on the rampage when there’s a rogue extension or when Google Chrome’s plug-in settings are configured to run everything by default. There’s a long list of the plug-ins supported by Chrome here, but most users in the Help Center forums seem to run into trouble when it’s working with Flash content.

Disabling Helper’s auto-helping is easy, and it won’t prevent you from using plug-ins. You’ll just have to opt in to view plug-in content on a case-by-case basis. Deactivating it isn’t entirely intuitive, though—there’s no mention of the Helper outside of your Activity Monitor and forum complaints. You’ll have to dig a couple of levels deep into your Chrome settings. First, shut down all your Chrome windows without quitting the program. In the Chrome menu, go to “Preferences,” scroll all the way down in the menu, and click on “Show advanced settings…” The first item in the expanded advanced settings list will be “Privacy,” and click on the “Content Settings” button right under that. About halfway down the content settings list is a “Plug-ins” entry, which will likely be set to “Run automatically.” Instead, select “Click to play.” This is essentially the same thing as configuring email to load images only when you click a “load images” link. Any embedded Flash, Java, Quicktime, DivX, or Silverlight content on a webpage will appear as a grayed-out space until you click on it to load the player and the content.

Running pipe commands as super user in bash

sudo sh - c '[command]'

sh -c is needed here to execute that command in a root subshell. This is because sudo echo out > direction would execute echo as root, but the redirection (> direction) would be done by your current (non-root) shell. You could also just do this su root.
