I just upgraded my OS on my MacBook Pro to Yosemite.
If you have a Mac and haven't yet performed this upgrade, DON'T!!!
Although it has some cool features and a nice look, it is super RAM hungry and pretty much guaranteed to reduce performance to a crawl. All functions on my machine are now significantly slower and more buggy than with the previous OS. Other problems include non-functioning USB ports and failure to recognize a keyboard on my mom's new iMac, and a completely corrupted hard drive on my daughter's MacBook Pro, which she how has to wipe completely. Apple has no answers yet.
Wait until they fix this crap before you ruin your computer. This new OS really, really sucks.
