With little fanfare, Apple began selling the new iPad mini with Retina display on 12 November 2013. Currently, your best bet seems to be to order online and wait 1–10 days for shipping, but Apple is also offering in-store pickup for Wi-Fi models. (One interesting note: while the new iPad mini uses the same A7 processor as the iPhone 5s and iPad Air, it appears to be clocked at 1.27 GHz like the iPhone 5s, instead of the iPad Air’s 1.39 GHz.) follow link
Set Password Activation Time in Snow Leopard
In Snow Leopard, you can now set an amount of time after your Mac goes to sleep or engages the screen saver before it requires a password to log back on. In Leopard, the option was simply to require the password or not. Choose among several increments, between 5 seconds and 4 hours, from System Preferences > Security.
