Mac Os X Lion Installation Dvd Download

I'grand going to walk through the process of making a bootable Mac OS 10 ten.7 Panthera leo installation drive out of whatsoever USB flash bulldoze key. This is similar to the process of making a bootable Lion installer DVD, only I prefer a USB flash drive because it's faster, smaller, and I take a MacBook Air and so an installation DVD isn't too useful for me.

This is pretty like shooting fish in a barrel to practice, but I have fabricated the walkthrough every bit unproblematic as possible with plenty of screenshots, so just follow along the instructions.

Requirements:

• A Mac with Mac OS Ten 10.6.8 so you tin can download and admission Lion
• 8GB+ USB flash key drive, these are cheap and ubiquitous on Amazon.com
• Download Mac OS X Panthera leo from the Mac App Store ($29.99)

Got all that? Skillful, let's go along.

How to Create a Bootable Mac Bone X King of beasts Installation USB Drive

We're going to assume you already have Mac OS X Lion downloaded from the App Store, if you don't, practice that showtime. If you have anything stored on the USB wink drive you lot're going to lose it, so be prepared for that and dorsum it up.

Beginning nosotros are going to locate the Lion InstallESD.dmg file and mount information technology:

• Navigate to your applications folder
• Correct-click (or control-click) on the "Install Mac Bone 10 Lion.app" and select "Show Package Contents"
• Open up the "Contents" directory then get into "SharedSupport"

• Double-click on "InstallESD.dmg" to mount the Lion disk image onto your Mac desktop, it will show up similar the epitome beneath

Next, we format the USB wink drive, this volition become the bootable Lion installer:

• Plug the USB flash drive into your Mac
• Launch Disk Utility
• Select your USB drive from the left side of Disk Utility, then click on the "Erase" tab
• Choose "Mac Os Extended (Journaled)" as the Format, and proper noun the USB fundamental what you want
• Click on "Erase" to format the USB drive

At present that the USB flash bulldoze has been formatted to the appropriate filesystem, we are going to restore the previously mounted InstallESD.dmg file to the blank USB drive.

• Right-click on the USB drive in Deejay Utility and select "Restore"



• Now yous need to set the source disk for the restore. This is why we mounted the InstallESD.dmg file earlier, considering we tin just elevate and drop the "Mac OS 10 Install ESD" epitome into the "Source" – if yous didn't mount the image, you can manually locate and select the prototype file yourself by clicking on "Paradigm"

• Drag the formatted USB primal to the "Destination" and check "Erase destination"
• Exist certain you lot have the right things in the right places, you don't desire to format the wrong bulldoze – then click on "Restore"

When this is finished, your bootable Mac Bone X Lion installer drive is complete! You can now kick any Panthera leo compatible Mac with the USB drive, just plug the USB key in, hold down Selection during initial boot, and select the drive. Hither's what you'll see upon booting with the drive continued:

From here yous can format, restore from backups, or reinstall Lion. If yous're wondering about the other drives pictured, information technology'south because I am dual booting Lion and Snow Leopard, and "Recovery HD" is the small recovery partition that Lion installs on its own. This process should work with a standard external USB hard drive too, but I have non tried that specifically.

Advantages to making a bootable King of beasts USB drive:

• You tin perform a make clean OS Ten Lion install with the USB drive
• The Lion USB key bulldoze becomes a recovery disk with access to Disk Utility, re-installation, access Time Machine backups, and everything the Recovery HD sectionalization does
• Y'all volition have external media to recover and reinstall Lion in the event of total drive failure or some other catastrophe
