... you're installing something, you've clicked install, you walk away from computer. an hr later you return to computer to find that the drop down sheet for authentication has now appeared. one hr of installation time wasted.
due to this constantly happening to me, and software update always appearing... i have to look over my shoulder like every 5 mins when installing an update to make sure that it's still going. ugh. i thought macs were supposed to be simple and user friendly. can't they just know what i want and do it?
