However, these camcorder MOD files are not compatible with apple devices like iPad, iPod and can’t play on Mac.

Luckily, a friend of mine recommended me a MOD Converter for Mac which he tried very great. I download the free trial and found it's very easy to use, and can convert MOD to MOV on Mac for playing in QuickTime or convert MOD to MP4 Mac for apple iPad, iPad 2, iPod, iPhone 4, etc. Then I bought it without any hesitating. If you have the same problem with me, maybe you can try it. Learn the details about how to convert MOD on Mac! Hope to help you.
