I'm running an Mid-2012 MacBook Pro, smoothly running El Capitan with a 1TB SSD, and 8GB RAM. I was looking for a thread that covers my question, so apologies if I missed it. But should I upgrade to Sierra now, or wait until a few more bug fixes are addressed? What is the advantage of upgrading to Sierra? I know it adds Siri, and there's a universal clipboard, but in terms of practical use, what am I really missing out on? I ask the question because it's a busy time of year for me, and I can't really afford to muck around with a lot of new compatibility issues, and Mail issues, etc. I also use a fair amount of older apps like iPhoto. Thoughts?
