My 2010 i7 iMac running off an internal SSD is currently on OS X 10.8.5. I need to upgrade it to at least 10.9 to use a certain software package because they stuck fixes for a 10.8 compatible version in with a feature that necessitated a higher OS version!
My question is this:
I have a simple choice between 10.9.5 and 10.10.2 are there an major issues/gotchas with either of these versions that I should take into consideration? Privacy? Network issues? Compatibility issues?
The trouble with all the searches I have done so far is that they mainly turn up puff-piece reviews by kool-aid drinkers that evangelise any and every upgrade and cloud integration whereas I want the warts and all info.
I have noticed the Spotlight sends queries to Apple and Bing which can be switched off. The continuity/handoff stuff isn't applicable as the iMac is pre-BT4.0.
Is there anything privacy invading or regime/doctrine changing between Mavericks and Yosemite that may lead me to choose the former over the latter rather than just use the latest?
I am in the process of testing with each but, as you can guess, that is a highly involved and long-winded process that will likely leave some stone or other unturned.
