How to make an OS X Lion USB thumb drive

Here are three different ways to put Lion on a USB thumb drive. If you buy and install Lion from the App Store  it downloads all 3Gigabytes from the App Store, installs Lion, then deletes the installer!  So when you go to install it on another machine it needs another 3Gigabyte download! Here’s how to make a re-usable installer.

Option 1: Put a full bootable Lion installation on the USB Drive with a recovery partition.

What you need: an 8G thumb drive and OS X Lion from the App Store.

What you get: A USB stick you can boot off and repair your Lion installation from.

Download the Lion installer from Apple App Store. DO NOT INSTALL IT ONTO YOUR COMPUTER OR THE INSTALLER WILL DELETE ITSELF. MAKE A COPY OF THE INSTALLER.  If you have already installed it and it has deleted itself,  go back into the App store and click on ‘purchases’ and next to Lion it will say ‘Installed’. Now option-click on ‘purchases’ and ‘installed’ will change to ‘install’ so that you can re-download the installer.

Format your Thumbdrive using a GUID Partition Table, and ‘ Mac OS Extended (Journaled)’, then you can run the Lion installer and install Lion onto the thumb drive.

Option 2: Create a Lion Recovery Disk.

You’ll only need a 4G USB Drive for this option.

What you get: A USB stick you can repair your Lion installation from, but not run Lion from.

If your Macintosh has an existing Lion Recovery partition (this will be the case if Lion came pre-installed on your machine when you purchased your computer from Apple), you can use this method. It will not be a fill installer but it will use the internet to install Lion onto another computer. It involves downloading a program from apple called ‘Lion Recovery Disk Assistant’

To test if you have a Lion recovery partition, Just hold down Command-R during startup and Lion will give you the option of going into recovery mode if the recovery partition is there.

Option 3: Make a Lion Installation USB Thumb drive like the one you buy from Apple.

What you get: A USB stick you can install Lion from – like the one that comes from Apple.

You’ll need an 8G USB thumbdrive.

1. Purchase and download the Lion Installer via the App store as in Option 1 above.

2. Right-click on the installer and select “Show Package Contents” and find  the file called  ”InstallESD.dmg” in the SharedSupport folder.

3. Use Disk Utility to ‘Restore’ this dmg file to a thumb drive to make a Lion Installation USB drive like you buy from the Apple Store. (the thumb drive must first be formatted as Mac OS Extended (Journaled) with GUID Partition Table.)

How to Air Print to ANY printer from your iPod, iPad or iPhone

Apple has introduced a ‘print’ button onto iPads, iPhones and iPods to allow you to print directly to a printer from your iOS device. Unfortunately  you need a special AirPrint enabled printer. Thankfully there is a free application called ‘AirPrint Activator’ that allows you to print to any printer, here’s where to get it and how to use it.

AIRPRINT

On your iPhone at the bottom of some apps is a ‘share’ button. If you click this button you get a menu of different ways to share the content, one of these options is ‘print’ as shown below.

Share Button

Print Button

When you press the ‘Print’ button you will be given an option to choose a printer, but unless you have a special AirPrint printer’ you will see no printers here at all.  (I have a Canon IR5000, a Canon inkjet, a Xerox and a HP and none of them are AirPrint!)

If you don't have an AirPrint printer there will be no printer here to select

AIRPRINT ON NON-AIRPRINT PRINTERS

If you want your non-airprint printer to appear then you can download the following free application called ‘AirPrint Activator’ from netputing.

Click here to go to the netting page to find the latest  AirPrint Activator.

Click here to download version 2  directly.

This will download a little application called ‘AirPrint Activator’. You may need to click on the ‘downloads’ button in Safari to find it.

Click on the 'Show Downloads' button to find it.

Now run airPrint Activator by  double clicking the AirPrint Activator application. You should get a window that looks like the one below. Press the slider to ‘Turn On’ AirPrint.

In order for a printer to appear in AirPrint Activator you need to give people permission to print to it by sharing it. To do this go to System Preferences (Under the Apple Menu on the top left of your screen) and then Click on ‘Print & Scan’.

To find printer sharing click on 'Print & Scan'

In printer sharing preferences you need to select your printer on the left and then click the ‘Share this Printer’ box.

The Printer should now appear in your iPad or iPhone printing menu!
