Can I install Aperture 3 on iMac with no disc drive
Is it possible to install Aperture 3 on iMac using product serial number (my PC has no disc drive)?
There is no longer a way to download a full version of Aperture from Apple's sites, other than the most recent version from the App Store. If you still have the installer disks, try to borrow an external DVD reader or ask a family member/fried with a computer that still has a DVD drive to create a disk image from the DVD. Then copy the Disk Image to a thumbs drive. If a Mac with a DVD drive is available on your local network, you could try DVD sharing.
