I'm at the end of unlocking my bootloader from the HTCdev site, and i completed all the steps. but the site doesn't shed much light for mac OS x users. I'm on the last step and can't seem to figure out the last terminal command to unlock the bootloader. HTC emails you the 'Unlock_code.bin' So in the Terminal i type '~/Desktop/Android/fastboot flash unlocktoken Unlock_code.bin' and get an error saying that 'Unlock_code.bin' cannot be opened. Any thoughts?! please if you know how to fix can you let me know.
