"macOS Sierra cannot be installed on '(null)'."
What a great start...

welcome to the future.

I've downloaded it but don't have the guts to press install. Waiting for others to find out which software crashes until I upgrade. I've been scouring Google, a number of issues already surfacing.

Installation has completed and I'm being greeted with 26 G of space more. Looks suspicious...

Have no fear sierra is here 😂

That's why I always wait a few weeks before upgrading, all those bugs are usually solved by then.

I wouldn't install Sierra JD you do iOS or Mac app store development, uploading a release using X code was broken since the first beta and still wasn't fixed 3 weeks ago when I last used it.

I just updated to sierra.. after I saw the null issue I panicked, cancelled and restarted installation. This time it said installing on Macintosh (or whatever).
Didn't break anything for me and aesthetically.. well, looks same as X to me.

I took the plunge and installed it last night. So far so good, only thing I can see different is the Siri integration, which is just as shit as on the phone. No real speed boost, it's probably slower. Still prefer Safari to any other browser though. Coda has been updated and the affinity apps so I'm sorted.
