Deactivating processes using Terminal:
Warning: incorrectly entering code in the Terminal Application can permanently disable your computer. It could require that you reformat and reinstalling your entire boot drive.
Did you test your bootable backup? Always a good idea.
The Terminal application is a text-driven command-line interface that allows you to communicate directly with the Unix-based operating system at the core of OS X Yosemite. Unix is the lowest possible level of human interface above machine language, giving the most streamlined and direct control over Yosemite.
I’ll show you how to use Terminal to remove Apps and processes that are set running by default when Yosemite boots up .
To launch the Terminal application, activate Launchpad, go into the Other folder, and click on the Terminal icon. The Terminal interface will appear. Now you are ready to enter commands into the command-line.
Tip: to minimize the potential for error I recommend you copy the commands and paste them into the Terminal’s command-line.
Remove Mission Control: copy/paste the following lines into Terminal’s command-line one at a time and hit the Enter key after each one:
defaults write com.apple.dock mcx-expose-disabled -bool TRUE [Enter]
killall Dock [Enter]
Remove Dashboard: copy/paste the following lines into Terminal’s command-line one at a time and hit the Enter key after each one:
defaults write com.apple.dashboard mcx-disabled -boolean YES [Enter]
killall Dock [Enter]
Remove Spotlight: copy/paste the following into Terminal’s command-line and hit the Enter key:
sudo launchctl unload -w /System/Library/LaunchDaemons/com.apple.metadata.mds.plist [Enter]
In order for the following command to take effect you’ll be required to enter your administrative password and hit the Enter key.
Note: the password for Mojo Audio optimized systems is: “Mojo.”
Remove Automatic Termination: copy/paste the following into Terminal’s command-line and hit the Enter key:
defaults write -g NSDisableAutomaticTermination -bool TRUE [Enter]
Resetting Yosemite to quit Finder: copy/paste the following into Terminal’s command-line one at a time and hit the Enter key after each one:
defaults write com.apple.finder QuitMenuItem 1 [Enter]
killall Finder [Enter]
Important! Quit the Terminal Application.
To maintain optimal performance, each time you reboot your computer, and each time you use Finder, you will need to follow the instructions below to manually quit the Finder Application. Since Yosemite needs at least one Application to be open before you can quit Finder, you’ll need to open your player or primary software first.
Click on the Finder icon in the dock.
Select the Finder column in the top drop-down menu next to the Apple Menu in the upper left corner of your screen.
Slide down to the bottom row and select Quit Finder.
You’ll know Finder is not running if the dot under the Finder icon in the dock is gone.
