"I just moved into a new apartment and have been reading about all of the new power strips out there, especially the green ones. I was wondering if you had any suggestions about which "green "power strips are out there with decent joules ratings. And when I say green, I mean power strips that have the remotes or switches to turn off all electricity flowing to certain plugs and with at least 2 plugs that are always on. I was looking specifically at sub $50 because I will need two, but if that is not possible I could be convinced otherwise. Thanks!"
Notice the word tried.
The log in screen states you need to log in with either you Apple ID or your iTunes account ID. I submitted my Apple ID and got back a screen telling me this was an in invalid ID. I should contact iTunes and fix things.
I'll leave out a lot of details here where I look all over Apple's web site trying to find a way to actually contact anyone. Called Apple and was told I should contact iTunes and see if they could fix the problem or, just maybe, my Apple TV is broken.
Used Apple's Call and Expert feature and was told Apple sees this download as a kind of "purchase" from the iTunes store even through it is being done at no charge. To get the download the customer MUST have an iTunes account.
When I protested that this was, after all, a software update the response was that I should create an account including submitting my credit card info, do the download, then log back in and delete the account.
Hmmmmm.
