Apple is being criticized for the lofty price of its newly-launched Pro Stand, which will sell for US$999, released at the company's annual developer conference on Monday.

The revisions previewed Monday during a conference in San Jose, California, included a new feature that will let people log into apps and other services with an Apple ID instead of relying on similar sign-in options from Facebook and Google.

The bug could potentially give attackers with physical access to a machine unfettered access to it without a password.
