Looking for some "how to" advice on upgrading software from(Late Year 2011) 15" Mac Book Pro Lion 10.7.5 to newer Yosemite OS X. I'd also like to remove all old non-working Power PC Apps and any other junk, bugs or viruses it might have. Looking forward to anyones opinions or recommendations on these upgrades. Thanks H.
MacBook Pro (15-inch Late 2011), Mac OS X (10.7.5)

If you're set on Yosemite the site is here:
