Upgrade from Yosemite to Sierra?
This weekend I might "attempt" to install Sierra to my late 2009 iMac currently (8GB RAM, 1TB HD) running Yosemite. I say "attempt" because I tried to install El Capitan about a year ago when it first came out and that didn't go well at all! Thank God I had Yosemite and all my stuff backed up with Time Machine on an external 1 TB HD! Since then, I haven't gone near trying to upgrade to El Capitan again and due to that experience, I'm leery of trying to upgrade to Sierra. Yosemite runs fine for me and doesn't give me any problems. My system meets the requirements for Sierra, but then again, it meets them for El Capitan too, but that apparently doesn't mean anything. My main question is should I upgrade from Yosemite to Sierra? Is it worth it? Has it been out long enough that the bugs are worked out of it and, unlike El Capitan, install smoothly? Thanks!
iMac, OS X Yosemite (10.10.5)
