Mac App Store – Online-Order

Mac App Store
The app will be ordered, downloaded and updated from the Mac App Store. You have to delete any preinstalled trial or older version first. Updates of the software will be delayed a bit due to the review process at the Mac App Store.

Currently only the full versions of GraphicConverter, CADintosh, EXIF Sync and iCalamus are available. Because the Mac App Store does not support upgrades.

Buying older versions

If you need a license for an older version of GraphicConverter you can purchase the latest version and e-mail us with the ordering details. We will then send you the serial you need free of charge.
