My early 2011 Macbook Pro is almost full right now, and I was thinking about formatting and installing the new OSX Mavericks, because it's free.
Since my Macbook came with OSX Lion 10.7.5 already installed, I don't have any disks, and I'm not quite sure whether my OSX Lion version is "tied" with my Apple ID or with my machine.
The question is:
How can I be sure that my Apple ID has OSX Lion in it?
If no downloads for OSX Lion are available on my account, can I just download OSX Mavericks and burn it on a DVD and then boot it as new?
I used this and I was able to burn the ISO in Disk Tools and it works... Takes forever to boot, but now I have a DVD that can install Mavericks.... and an ISO too! :)
You don't probably need any bootable installation disk or USB drive.
You can first erase and reinstall 10.7 from the recovery partition. Hold command-R on startup, erase the OS X volume from Disk Utility, and choose Reinstall OS X. See OS X Lion: Erase and reinstall Mac OS X. Then upgrade to 10.9 from App Store.
If your Mac came with 10.7, you can reinstall 10.7 from the recovery partition, but you cannot download 10.7 for free from App Store.
Is there a utility built into the Mac software to allow for burning ISO downloaded from the internet.
Or.. Is there a better utility on the Net for performing this function?
The steps below show how to use the Disk Utility functionality. (Copied from Life Hacker).
Alternatively you could use a third party application like Burn
It's very, very easy to do on the command line (open Terminal):
hdiutil burn /path/to/iso
If it's a CD/RW and you want to erase it first:
hdiutil burn -erase /path/to/iso
It's funny, but this is pretty much the best CLI for CD burning on any OS.
You can use the "Disk Utility" program that comes with the OS.
Click on the Finder icon in your dock, then on the sidebar, click on applications.
Find the folder that says "Utilities" and double click on it. Find the application that says "Disk Utility" and on the Menu Bar, go to "Images" -> "Burn" and select the image you want to burn.
