Mac and tv use

Hello and welcome, 

What file system did you used to format the Passport? If you used HSF+, then you need to check if your TV is compatible with that format. Most TV’s are compatible with FAT32, which is also compatible with MAC’s, the only limitation is that you won’t be able to save larger files than 4GB, check the TV manual to see what files systems work better for your.
