Anne,
Hi —
In my “technical” experience of doing support. Of all the hardware, there’s never been a time when I personally was required to unplug my external’s just to upgrade my o/s. (This is my personal experience….there are times however, when unplugging peripherals will help troubleshoot hardware problems, and potentially software problems also.)
I’m sorry to hear that you had the experience with the Snow Leopard.
What was the problem you had exactly when you had an upgrade?
What “driver” was it, do you know?
(Let us know what other information you know about the problem…)
—– From what I know about the great Apple, My hunch is that they (like many other companies) would not want people to have to unplug all their things just to do an upgrade. I’ve had extremely good experience with the o/s and their Hardware. ——– I cannot speak for them, or Snow Leopard. I’ll let someone else address you directly who has more experience about upgrades to Snow Leopard —
Let us know,
Matt
