It's possible to use a Mac with your CLiKAPAD voting system but we recommend a Windows laptop as you cannot run ppvote natively on a Mac.
The software is not compatible with Mac OS and will only run on a Windows operating system.
However you can run Windows on a Mac computer, there are various options for this including the built in Boot Camp utility included with Mac OS or using a 3rd Party solution such as Parallels. Both of these options work fine with the voting system but it depends on how much integration with the Mac OS that you require as to which solution is best suited to your needs.
