Has it finished yet? Mine has been saying between 40 and 50 minutes remaining for over two hours now. It's never ending!
Yes it has finished, mine took awhile as my backup drive is a spinning HD and I have 1TB of data (moving onto my new 2TB mac)
I have a further couple of things, my old Mac was running El Capitan - Mission Control is annoying as hell in Sierra, i'm used to 4 finger swipe up to deactivate it and now it just bounces - also if I do a fast 4 finger up gesture mission control seems to get stuck - I thought it was a graphics lag or something on the machine, but looks like a software glitch - no idea why they changed it
After using this keyboard I actually love it, I now type a bit more quieter then before but still loud (i'm slowly retraining myself) - I haven't found myself making any mistakes as I seem to be typing faster then I did on the old one. I don't find myself using the quicktype suggestions on the touchbar because I type so quick on this thing that the suggestions don't come up quick enough.
The speakers are amazing!! literally I don't need them any higher then 60% - 70% and i'm really happy, the previous laptop (I had late 2013 model) was a good speaker but wasn't loud enough for my liking.
I still love the large trackpad but I do find that sometimes when resting my hand on the very edge it clicks (so the palm rejection not working)
Screen brightness is great I don't need it at full to be happy, look forward to trying it in the summer and see how it displaying in direct sunlight!
So far it is coping with my work load which consists on having the maximum about of files your able to open in Photoshop, 2 browsers each with around 90 times, various pages and numbers documents, terminal, xcode with a few projects open, a VM (parallels) with Mavericks (for some legacy apps I need), mail, iTunes and messages as well. My 2013 struggled like hell to keep up with the amount of things I open and SO FAR this is doing a good job.
The smaller footprint while it doesn't look much different when you compare side by side, it actually feels a lot smaller when using it - I think possibly the darker colour and the small bezels gives an illusion of a much smaller device.
For reference I have the 2.7ghz 2TB 460 graphics 15" model
