Hello, La Luz de La Luna,
To upgrade your preinstalled iLife applications you have to accept them as purchased with your AppleID.
Launch the App Store and sign into your account. Then go to the "Purchased" tab. Here the iLife applications should be waiting for you to be accepted. Click the "Accept" button. This will register them to your current account. Now you should be ablet to upgrade them using the App Store.
- Double-click the App Store icon in the dock.
- Enter your Apple ID and password.
- Click Purchases.
- If you haven't previously accepted your bundled iLife applications within the Mac App Store, you should see your iLife applications appear in the Accept portion of the screen. Click Accept.
- You may be asked for your Apple ID and password once again. Your iLife applications now move to the Purchased section. These applications are part of the software that came with your Lion based computer. Your account will not be charged for them. Click Install to complete installation of your applications.
Perhaps you didn't understand my question. The Mac was second handed and I was not the person who purchased the softwares. Now, as I tried to upgrade them, I couldn't because I don't have the apple ID (unique) of the previous owner, who purchased the softwares. As I tried to uninstall all the softwares and buy it anew from the app store, I couldn't do that either. Somehow, the app store recognized my Mac and thought that I had the softwares on it. I was prevented from doing anything further since the second step about entering Apple ID and password (you know what I mean right?). Thank you so much for the great effort to restate and respell things that everyone knows. It does take great patience of someone to do that.
I got my Macbook pro for a few months now.
Sorry, from your first post it did not follow for me that your mac is second hand. That changes it considerably.
The previous owner will have to contact Apple and to unregister the iLife Applications and to transfer the ownership to you. Right now you are using pirated software, for the previous owner was supposed to sell the mac with the system wiped clean.
Otherwise your only option is to delete the iLife Applications, sign into the App Store with your account and to buy them to your name. Then you will be able to update them, as you are now the owner.
