Haven't updated since Snow Leopard
I'm several updates behind. I believe Snow Leopard is the latest update I did on my MacBook Pro.
OS X
Version 10.9.5
Processor 2.66 GHz Intel Core 2 Duo
Memory 4GB 1067 MHz DDR3
Now there is Maverick, Yosemite, and El Capitan.
When I've read reviews in the App Store, people talk about problems, and I've been nervous to update. The one thing that really stays in my mind was a comment that iPhoto got all messed up and jumbled the photos. I don't remember what else made me nervous; I just know the reviews were what kept me from upgrading.
I haven't loaded my Mac up with a lot of 3rd party stuff. I have some 3rd party, but not tons. Mostly it's what I can get from the App Store.
I'm open to suggestions. Should I update? To what operating system? Do I need to work my way through the older ones first?
I love my Mac, but I'm not a techie. I also don't have any Mac users who can help me.
Thanks.
