Has everyone installed this FIRMWARE update with no problems? Neither the software nor FIRMWARE Update process with an Apple operating system actually depends on the Internet connection does it? In other words, the update files are completely downloaded to the machine's hard drive and then the update is applied from there, right? The description seems to indicate that this FIRMWARE upgrade will be completely downloaded first as some type of installer package so I guess its installation does not depend on the Internet connection. Am I right? Do I need this FIRMWARE update? Should I install it just because it is available? The primary issue that its description says it addresses is mb/mb Pro not responding to the first keyboard key pressed if the machine has been idle for an extended period of time. I actually have not noticed that issue and I probably would not notice anyway, but I guess they mean all machines are affected by it. The Internet connection that I would be using in this case is one of those wireless connection cards that works through a cell phone provider. Incidentally, I have installed all of the SOFTWARE updates.
