I have OS X 10.9.5. The rename option is not available to me. I can rename one by one by clicking and enter method but if I want to rename multiple files it is impossible. I have tried safe mode and using the back up on my time machine thingy to take it back to when i got it but it seems Ive never had the option. Is there something Im doing wrong? maybe a setting is wrong? I don't have enough data on my internet plan to upgrade just yet... help me :-(
