You can not connect your jvc everio gz-mg330 to your iMac with snow leopard?

The JVC Everio GZ-MG330 uses a proprietary file system that may not be directly compatible with macOS Snow Leopard, which can lead to connectivity issues. Additionally, the camera might require specific drivers or software that are not available for Snow Leopard. To transfer files, consider using a card reader or transferring the footage to a PC first before accessing it on your iMac. Alternatively, you could use third-party software designed to facilitate file transfers between the camera and your Mac.
