Boz Posted July 17, 2011 Share Posted July 17, 2011 Though very retarded and disorganized, creating a clean install without installing Snow Leopard first is fairly simple. To download OSX Lion you do have to do it from a computer with Snow Leopard 10.6.6 and above (due to the app store condition). Lion will not be distributed on the physical media or anywhere else. (One of the ways how Apple wants to make everyone use Mac App Store). So, once you download OSX Lion it will automatically start the installation procedure.. before you click anything: 1. Go To Applications and find a filename called Install Mac OSX Lion. 2. Back That file to a hard drive or wherever just you have a copy so you can make a new DVD or USB when you need it 3. Now you need to right click on the above mentioned file and select Show File Contents 4. You will go into Contents folder and then Shared Resources and located a file called InstallESD 5. You can either burn this InstallESD.dmg with the Disk Utility but Lion installation from DVD drive can take forever. So it is recommended to use the USB stick. To use USB Stick you will do the following in Disk Utility: A) Locate USB stick on the left B) Select it to be active C) Click on the right side to RESTORE tab D) Drag the InstallESD.dmg to the SOURCE textbox and drag the USB source to DESTINATION textbox, so it looks like this: E) Hit Restore and wait until it's done When it's done your USB stick is ready to be used as startup and install for OSX lion 6) Boot your Mac and hold the ALT key to pick the boot source 7) Choose your DVD with Lion or USB stick and you are on your way There you go. cyrl, Nothing Here and SuperKid 3 Share Link to comment Share on other sites More sharing options...

evo0o Posted July 20, 2011 Share Posted July 20, 2011 Anyone who has done both a clean install and an upgrade install care to share their experiences on which is better? I've always been ok with Apple's upgrade install but many are claiming that Launchpad has unwanted/ deleted items so I'm a little apprehensive as I'm just a neat freak like that... :p Link to comment Share on other sites More sharing options...

Southern Patriot Posted July 20, 2011 Share Posted July 20, 2011 If that DMG is compressed (which it likely is) then it isn't going to restore onto a 4GB flash drive, it is going to need a larger one. iUserX 1 Share Link to comment Share on other sites More sharing options...

Not sure I fully understand your confusion to be honest. Disk Utility gives out an error saying the target disk doesn't have enough free space, which means you need a higher capacity drive. Seems pretty straight forward, no? The restored DMG requires a total of 3,8 GB of free space, your drive only has 3,65 GB. It should be noted that the capacity of any drive ? formatted capacity. iUserX 1 Share Link to comment Share on other sites More sharing options...

I'm not confused, i have a 4GB USB disk so i assumed that would work since thats what is being talked about on the first page of this thread, so you need at least a 5GB USB disk, not 4GB Link to comment Share on other sites More sharing options...

The first post clearly shows an 8 GB drive being used for the process. Any external drive or DVD-R(W) will do as well. Good luck! Link to comment Share on other sites More sharing options...

Zoom7000 Posted July 20, 2011 Share Posted July 20, 2011 I've already installed Lion before I could burn the DMG and now I can't see the install file anywhere. Looked in /Applications and did a Spotlight search too. Does the Lion installation delete the file? If so, how can I re-download it from the App Store?

.Neo Posted July 20, 2011 Share Posted July 20, 2011 Do not know if it's possible to re-download from the M.A.S. You can re-download all applications from the App Store. Including OS X Lion and Xcode. Personally I just made a backup on my external drive. Link to comment Share on other sites More sharing options...
