I am using my passport as a time machine for my mac and when I try to use it with my bluray player or my brother’s computer, It starts up but isn’t recognized. It’s great but I can only use it on my mac as of right now which kind of **bleep**. Someone help.
Because your drive is preformated for mac. If you want to use it in a blue ray player or a windows pc, you just need to reformat it to fat32, however time machine is not compatible to fat32 drive format.
