i think we have a troll
to TRULY brick, todays modern technology is ALOT more difficult then just ****ing an update up.
See... the core hardware runs firmware... as long as the firmware remains in-tact the hardware can still run, and can still process software.
When you do a software update, you will almost NEVER be touching the firmware files... in fact firmware updates are cmopletely seperate and done in a different method (for safety's sake... because yes your correct there'd be MANY pissed of cusomters is an update truly did brick a device)
WORST thing that happened to your macbook is it wont boot up passed the white screen, and wont go passd a spinning gear. In whcih case there is MANY things you can do and your FAR from bricked.
Either, become educated or stop trolling
