Yes, yes, yes!!! I love scrapping on my Mac, the 27" iMac. My eyes are too old for my 13" Macbook these days tho I do use it sometimes when we travel. I'm on PSE10 with Mountain Lion. I don't find it slow or buggy but I do have a lot of memory (8gb) and keep all my digi supplies on an ehd. I did order PSE11 for the action installation ease and it's now on sale at Costco for $49. which includes a "how to" dvd and some supplies.
I too had years of experience on PCs tho not scrapping, and found the Mac world more intuitive despite my PC training. Both my dh, and then my son <--who said he'd never ! get a Mac, have gone that way. None of us has ever had a virus in almost 5-6 years of use either. The virus and security issues were what got my dh to change.
Have fun!
