** macOS Sierra / OS X 10.12 **

You serious? They've removed the time remaining estimate?!

Not sure which OS version was being referenced but i'm on 10.12.1 and the estimation is still there.

I'm still running OS X Yosemite on my iMac (late 2009 - so quite old now). Is it worth upgrading to Sierra or will this have a negative effect on performance?

Interested to see if anyone else has upgraded an old Mac.

Backup, try it and restore if you get major problems. Try it out for yourself if you have few hours spare.

I just updated all my devices.

I don't see any reason why you wouldn't want to update. MacOS is pretty good.

Good stuff.

Well that went well.

Went to upgrade my MacBook and it simply won't let me. My guess is it's too old as it's a MacBook aluminium unibody (just after they stopped doing the white MacBooks and before they started calling it the pro).

Good stuff.

10.12.2 was where it was to be introduced.

10.12.4 is now available via Software Update.

Hello Night Shift, RIP f.lux.

Or if you prefer, the combo update is here.

Bah, Night Shift isn't available on my 2011 iMac.

It's nature's way of telling you that you need a 5K iMac in your life!
