Using Passport Drive on both my PC and iMac

I am going on a long trip and will be taking many large file photographs. I plan on dumping them to my laptop PC daily and backing up to a Passport 2T drive. I will then come home and want to put the images into my iMac for editing. Will I have any problems doing this. this is a once in a lifetime trip and do not want to come home and not be able to work on my images.

A drive formatted NTFS will be read only on a Mac. You can reformat the drive to FAT32 but the biggest file it will accept is 4 gig. There is software that might work If you can find a link for NTFS-3G that still works It went pay and many links no longer work. Checkout this post for a few more see post 6
