In my personal experience, it seems feasible.
I know the fact that QuickTime MOV extension can be changed to .mp4 and works available.
If you want to view the MOD files on a Mac, you can download a versatile player like VLC, plays pretty much of video/audio files.

If you want to handle MOD files on Mac for specific using such as syncing to iOS device, or import into FCP for editing, then you should convert them using a third-party conversion utility.
I have been using AppGeeker for a long time and it can convert almost anything to anything (in batch as well). Audio or video. Got if for one specific thing, but now use it almost daily for a variety of conversions.
