How do I install iDVD on my iMac os x 10.7.5?
this version is no longer available and it is necessary to write the projects made with iMovie or iPhoto.
If you have an older Mac that came with iDVD preinstalled you can use the Software Install disk that came with it to install iDVD on your new iMac. It might look like one of these:
If you don't have those disks you'll have to purchase an iLife disk from a 3rd party retailer like Amazon.com to install iDVD.
If you have to purchase an iLife disc remember that the iLife 11 disc only provides iDVD 5-7 themes. The Software Update no longer installs the earlier themes nor do any of the iDVD 7 updaters available from the Apple Downloads website contain them.
Currently the only sure fire way to get all themes is to start with the iLife 09 disc:
This shows the iDVD contents in the iLife 09 disc via Pacifist:
You then can upgrade from iDVD 7.0.3 to iDVD 7.1.2 via the updaters at the Apple Downloads webpage.
