I'm very happy with my current desktop/laptop setup under Mavericks, but if I want to take advantage of several features of my new iPhone, I need to upgrade to Yosemite. I'd rather not, am I just being dogmatic? (Petty I know, but I really dislike the system text font, which apparently you cannot change; plus there may be other ill effects from my audio/video apps and their many plug-ins, some of which are a bit long in the tooth).
I'm particularly interested in SMS Relay, where the iPhone will push SMS Text Messages to the Messages app which can then answer and relay back to the phone. Previously, I had an Android and accomplished this with Mighty Text or MySMS, both of which work quite well and have dedicated apps for OSX and the iPad- but their iPhone app won't work on the 6 because it won't allow them to access iOS' text messaging.
The VERY weird thing is, I tested MySMS on my friends iPhone 2 weeks ago- and I swear I got it to work somehow (it took over SMS from the Messaging app).
Anyway, yeah, I can set up a test partition and test everything under Yosemite, but wanted to see if any of you guys had insight into what might bite me 6 months down the road...
OR
if there was a hack for allowing MySMS to work with the iPhone.
