I've had a PC for the last 4 years, and I recently bought a mac. I bought a WD My Passport Essential SE external hard drive. I was hoping I could use it to transfer my files from the old computer to the new, and then use it to back up the files on my mac, but it can't be compatible with both (without there being a 4 GB file limit). What's the best way to handle my files? Should I take on the laborious task of transferring them using flash drives, and then use it with Time Machine? Or is there a way I can use it to transfer my files too? Thanks!
