Software updates can be a bit of a mixed bag — just ask anyone who’s ever been on the other side of a botched firmware install. While many users react with itchy trigger fingers to download the goods, the more prudent (read: hardened) prefer to hold off in the event potentially crippling bugs creep on out. So, it comes as no great surprise that Apple’s recently issued Thunderbolt update version 1.2 — intended to add support for a Gigabit Ethernet Adapter — is subjecting a portion of frustrated users to unexpected errors and frozen boot screens. Currently, the only officially sanctioned remedy seems to be a fresh install of OS X Lion. So, if you haven’t already taken the plunge on this minor feature add-on, you’d be well advised to wait it out.
