On Snow Leopard the three lights listed in the firmware updater instructions are not flashing, only my rewind button is lit. Is something wrong?
This is a known issue in all versions of Mac OS X since Snow Leopard (10.6.x), this also applies to Lion (10.7), Mountain Lion (10.8) and Mavericks (10.9) and possibly future versions of Mac OS X. The buttons may not be lit, but it is in update mode. Please continue the update as instructed by the program.
