Hi all Anyone experienced this.? Applied the firmware 1.0 update today, but didn't go as expected. Apple should really tell customers in the same dialog that "Laptop owners need to be connected to AC power in order to apply update" I just found this out by accident, after noticing my laptop needed to be recharged. on the second attempt (with power) there was no progress bar.. the mac went to standby/power on after after software update installed like before, but in both cases it restarted as normal... The only way i could tell it was installed was via SU reporting all software was up-to-date. Its kind of strange.. you can install OS X updates/combo packs without AC power on laptops, but not major firmware updates.
