SimCity on Mac is 'totally unplayable'

I am really curious about what kind of internal turmoil is going on at the studio if an AAA title is shipped with this kind of quality despite numerous delays. Since they delayed it a few times, it's obvious that they KNEW the technical challenges and the issues it had, but somehow in the last minute the team went "Screw it, we'll do it live" and shoved it out of the door.

If brand new iMacs and Retina Macbooks are having problem with the game, it's obvious that the dev team just gave up towards the end (or were told to do so), since I doubt all of those problems escaped QA's attention.

This is EA and Maxis we are talking about here, not some indie studio being funded by Kickstarter. Either all of the competent staffs (QA, Eng, PMs) left one way or another or people just didn't give a fuck anymore in the end.

Considering the PR fiasco from the PC version earlier this year, this screw up is so atrocious that I'd more likely to believe they accidentally shipped the wrong build or something...
