Egad, I can't believe I stumbled onto one of these developer-orientedthreads and actually had a thought: If a mac is anything like aLinux-based system, you'll have to precede everything by 'sudo ' toget commands like fastboot and adb to run. I can well imagine that a PC will require that the user have adminprivileges as well, but I've never tried it from one.I don't think a re-locked bootloader status is a problem, one just hasto re-unlock it. The unlock.bin code is unique to the device, and isindependent of the owner. However, you will have to re-fetch it fromHTC using the web process.Good luck!cheers,john
