Ok, so I made a Time Machine backup before install lion ... it's on an external HD. Question is ... how do I get my stuff back now? First time I've ever used Time Machine.

There's an option in both the installer and when setting up your Mac right after your installation is finished. Alternatively you can launch Migration Assistant from /Applications/Utilities.

For those that have already upgraded to Lion and had the installer removed from their system, you can redownload it. Option+Click on the "Purchases" tab in the MAS (and keep holding Option until the page is loaded). That should enable the "Install" button next to OS X Lion.

I didn't know you could do that... So, it will let you re-download anything, should you want to re-install for w/e reason?

LOL I wish I would have known this before installing Mac OS X Snow Leopard again to download Mac OS X Lion...

Doesn't seem to work anymore for me. :s

Edit: Never mind, it works again.

Ok here is my question. Lets say you got a mac book pro with Lion preinstalled. And 2 days later you have a total hard drive failure where its totally unrecoverable. So you decide to get the hard drive replace. Lets say you decide to do it yourself. Just how do you get Lion back on the laptop? I know with the mac book air and mini's it has that internet install feature thats built into the boot up so even if you dont have a working install you can still go back. But what about the other macs? Also from what I been hearing there isnt a generic install for this if your upgrading using the usb method. Meaning it only works on the model you download it to even if you bought it for multiple machines to upgrade using the USB method. I am big on having my own physical media stored some where incase of drive failure, but in the case of Lion with multiple macs you bought licenses for how would you do this?

This does not work on the newest generation of Macbook Air. It fails to boot from the USB device (crossed out circle at boot).

Thats because they dont need it. They have something built in where as long as you have a network conection you can redownload and reinstall Lion where as the older machines can not do this.

      Nah. They'll milk the current generation in terms of design - controllers, consoles, but no meaningful hardware improvements. This is one reason why people aren't buying Xbox hardware - it's stagnant.
    • Dell, HP PCs ran into endless reboot, BitLocker recovery loops but Windows 11 isn't to blame

      Funny, but I didn't had the issue. All PC's at work are Dell and we had the culprit version of Support Assist for about 2 weeks until we got the new one. No problem at all. And for checking you can also use Dell Command Update, no need to search in windows settings. Just check the Upgrade History.

      Apple are scared of their customers! They have built a brand over the years of "it just works out of the box", but that slows innovation. Samsung's master stroke was the Galaxy Ultra: "Let's cram everything into one handset, make it so stupid only real nerds will love it, some of the features will work, some won't, but the audience will have such a high tolerance they won't care". Apple has no such device and so they are constantly worrying these days about the fallout of creating a new experience that customers might not like. I know it is often cited the reason they don't build a touchscreen Mac Book is they don't want to cannibalise the the iPad market, but I think it's equally cold feet after the criticism Microsoft receive trying to make a touch compatible desktop OS
