Terminal
One feature which seems to divide the masses is OS X’s ability to relaunch your applications on startup/reboot. This feature is know as Apple Persistence, which is personally a feature I am not really a fan of. It’s very rare for me to want the same applications on each use of my MacBook, asides from the obvious email and unified comms clients of course.

So – to disable to ‘persistent’ application mode simply follow these simple steps below

  1. Open the Utilities folder
  2. Open a terminal window
  3. Copy and paste the following line in:
    sudo defaults write -g ApplePersistence -bool no
  4. Enter your password and press enter

Now the next time you reboot, you’ll be greeted with your beautiful desktop wallpaper, and not the plethora of apps and browser windows.

If you decide you miss the feature, all you need to do is switch the boolean value back to yes:

sudo defaults write -g ApplePersistence -bool yes


ChromeGoogle Chrome for OS X generally doesn’t play well with proxy servers, especially those that require NTLM authentication. Those who have tried to use it in the past will be greeted with a constant barrage of proxy authentication prompts, each successful entry of credentials loads a tiny little bit more of the site..

However, there is a way to resolve this. Using a simple command in OS X terminal you can enable NTLM authentication in Chrome, and only have to enter your credentials once.

  1. Open Finder
  2. Open the Utilities folder
  3. Open a terminal window
  4. Copy and paste the following line in:
    Sudo /Applications/Google Chrome.app/Contents/MacOS/Google Chrome --auth-schemes="ntlm"
  5. Enter your password and press enter
  6. Now quit and relaunch all Chrome windows.

That’s it. You should never be prompted again, at least not until you change your password.



Mike Hudson WhoIs ScreenshotDid you know that you can obtain domain whois information for any web domain using
nothing but OS X Terminal?

For years I’ve used many web services including (and probably my favourite) CentralOps, however, sometimes its handy to be able to do things without leaving the comfort of your current terminal session!

So.. To get some of the information web services can provide, launch Terminal and type:

whois google.co.uk

NOTE: You can replace google.co.uk with the domain name of your choice.

WHOIS (pronounced as the phrase who is) is a query and response protocol that is widely used for querying databases that store the registered users or assignees of an Internet resource, such as a domain name, an IP address block, or an autonomous system, but is also used for a wider range of other information. The protocol stores and delivers database content in a human-readable format. The WHOIS protocol is documented in RFC 3912.

One of the powerful features of OS X built-in spotlight is its ability to search the contents of files for your search string.. However, for reasons yet unknown, I have found this functionality to sometimes be a little hit and miss..

Which is where Terminal comes in.. Using a single line terminal command OS X will rapidly return all the files containing the text you are looking for.

First of all, for this example you need to first set your current path in terminal to the folder containing the files you want to query.

Then type/copy & paste the following

So for example, should you want to find all the text files containing the word AppleScript, you would use the following command:

To expand of the example above, should you want to extend that and search sub folders all you need to do is add ‘r’ for recursive:

This will now return all text files in the folder and subfolder containing the term AppleScript.

One of the most used features on my OS X installs is the Quick Look feature, its much easier then launching an app just to check, or to quickly read off its content. However, for as long as I can remember Quick Look has always been known for causing delays in folder navigation, high CPU and high network utilisation. This is generally down to it rendering previews of movie files in the active finder window. Yes – this even includes items on your desktop.

There are a couple of ways to combat this speed delay without loosing functionality of Quick Look on other files.

The easiest is to remove the Quick Look generator from the quick look folder. To do this, click on Go > Go To Folder now type or copy paste /System/Library/QuickLook/ now either delete or if you’d prefer move Movie.qlgenerator to another location.

This will disable the thumbnails for movie files, and speed up finder navigation – especially for media heavy folders.
