iPad Air 2 — iOS 9
When I upgraded to OS 9 I didn’t specify a Passcode and have been using the iPad successfully without having to enter a Passcode ever since.
Instructions about upgrading to iOS 10 always has “Enter Passcode”.
Since I am not now using a Passcode can I upgrade to “10” and not have to use a Passcode as I have been doing?
Will “10” even install without a Passcode? I do not want to end up with a useless iPad.
I understand the security advantages of a Passcode but there is no need for one in my situation.
