Wonder how diligent the updates for 10.9 are going to be handled now that Yosemite is the latest and greatest. I wonder this because I ve read over the last month or two about some vulns that could have an effect on Mav. I am curious about whether Apple is going to throw us under the bus. Rather than go to Yosemite, I will instead install FreeBSD or some such other OpenSource OS on this MacBook Pro- I don't use an I Phone and don't much care for Yosemite. Any thoughts?
