Apple Diagnostics

Another recent discovery was that Apple have changed the traditional Apple Hardware Test for a more modern Apple Diagnostics program

Heres a little checklist for you to check that all your hardware is fully functional

 

If your Mac was released after June 2013, then you will need to run Apple Diagnostics

This is done by holding down D as you power on the machine

 

If your Mac was released before June 2013 and is running 10.7 or newer, then you will access a more traditional Apple Hardware Test

again, this is accessed by holding down D as you power on the machine

 

If your Mac is older, and won’t run 10.7 or above, then buy a new one 🙂

alternatively, Apple Hardware Test should be available on one of the original Mac OS installation disks

you’ve guessed it, insert the disk into the Mac, restart the machine and hold down D to access the Apple Hardware Test

 

If you’ve run the tests and you’ve got an error, then check out the following page for what the error code relates to

Create a Mavericks USB Key

Something that has been around for  while, but I’ve just stumbled across it, is Diskmaker X

This nifty app will do all the donkey work in creating a bootable Mac OS X USB Key, you just need to following

1. Mavericks Installation app from the Mac App Store

2. Diskmaker X app from their website

3. an empty 8GB USB Key

 

Once you have downloaded the Mavericks app from the App Store and Diskmaker X from their website, then insert your USB Key into your Mac

Run Diskmaker X

When prompted, choose 10.9

It will then look for your Mavericks app, when it finds it, choose ‘Use this copy’

Then if you are using an 8GB USB key, then choose  ‘An 8GB USB Thumb Drive’

If you are using a partition on a larger drive, then choose ‘Another kind of disk’

Confirm the choice of disk by clicking on ‘Choose this disk’

When it warns you about erasing the drive, confirm that you wish to continue by clicking on ‘Erase and create the disk’

You will then be warned that you will need to input your admin password, so click ‘Continue’ and then enter your admin username and password when prompted

The process is fully automated, so from now until completion it will take around an hour, maybe longer on slower machines, you will get a dialog box when it has completed, confirming this and asking you for a donation, it’s not compulsory, but as it is quite a useful app, its always good to encourage future development, so please consider it.

 

You can then boot into the USB from the Startup Disk option in System Preferences, or by holding down ALT when the machine boots up

 

Enjoy

Set Finder Preferences – Command Line

Setting  the following Finder Preferences enables the specified drives to be shown on the Desktop, the same as going to Finder, Preferences, General and ticking the boxes

defaults write com.apple.finder ShowExternalHardDrivesOnDesktop -bool true
defaults write com.apple.finder ShowHardDrivesOnDesktop -bool true
defaults write com.apple.finder ShowMountedServersOnDesktop -bool true
defaults write com.apple.finder ShowRemovableMediaOnDesktop -bool true

To set it so that a New Finder Window shows your home folder, enter the following into Terminal

defaults write com.apple.finder NewWindowTarget PfHm

Require Password after Screen Saver – Command Line

To ensure that your machine is secure, enable a password prompt by typing the following into Terminal

defaults write com.apple.screensaver askForPassword -int 1

To set a delay on it before it becomes active, type the following into Terminal

defaults write com.apple.screensaver askForPasswordDelay -int 300

The delay is in seconds, so the command above sets it to 300 seconds, or 5 minutes

Disable ‘Natural’ Scrolling – Command Line

This one is personal preference, but I can’t stand the unnatural ‘natural’ scrolling option, so I disable it on all of my machines, to do this from the command line, enter the following into Terminal

defaults write NSGlobalDomain com.apple.swipescrolldirection -bool false
