We love Mac too but at the moment our photobook software is only available for the Windows operating system, a native Mac version is on our development roadmap but in the meantime please try one of the solutions below.
We have many Mac users running our software using Windows virtualization software such as Apple's BootCamp or third party software such as VMware Fusion or Parallels Desktop. However if these options are not suitable we also accept photobook designs supplied in the PDF format.
If you have installed a compacted version of Windows (such as TinyXP) the software may display a 'Spooler Error' message. This Windows service will need to be manually started using the instuctions found here: http://support.clickonprint.com.au/forums/65383/entries/57741
Can I supply a PDF?
What other software can I use to create my photobook layout?
