Re: 7.1 upgrade
Must say I'm nervous about upgrading. Last time I upgraded my daughter's Mac -- in Nov/Dec 2013 -- it was the last straw for the logic board; the computer keyboard/mouse stopped working, despite repeated downloads and several calls and excellent help by a localish Apple reseller. Apple's service was great: For some reason, even though I'm neurotic about buying extended care for big electronics purchases, I hadn't bought Apple Care and it would have cost $600 to fix the Mac, whose warranty had expired 1 week prior. Yeah, figures! Apple allowed me to buy the warranty (about $200) because I'd actually called for service earlier in the covered period and they had not offered me the coverage at that time (or really addressed my problem).
Reading through InformationWeek and weighing the upgrade pros and cons.... although I know we'll have to upgrade it sooner or later.
