Just to let other OS X users know: the 1.7 patch is now available for OS X too. This is a prerequisite for direct download users who want to install WA, and (possibly) nice to have for the rest of us.
Official blurb:
http://forum.thesims3.com/jforum/posts/list/131447.pageDirect download of the version I used (note that I upgraded from 1.2.7, which is probably not very common - I guess you can modify the URL with whatever version/language you have):
http://llnet.thesims.cdn.ea.com/sims/u/f/sims3/mac/To-3043-1.7.11.002002-From-2706-1.2.7.00002.tgzWorth noting, perhaps: clicky-pointy "Upgrade" via the Launcher did not work for me ("failed to launch task: launch path not accessible" - might be either the usual Launcher crap or my paranoid network settings?). I didn't investigate, since the direct DL downloaded and installed without a hitch.
I've noticed a bit of a weird performance change - I didn't playtest much, just tested out build mode: on one hand, the graphics are more shiny now (some graphics features had been missing in 1.2.7/OS X - raytracing shadows, antialiasing and such, so now I have all of those (yay)), and there is a bit of lag when zooming around, which I kind of expected - on the other hand, my machine runs several °C cooler now and the fans are running much less at the same time. This might be a good thing, on the other hand it might mean that 1.7.11 somehow isn't using the full potential of this machine. I dunno, it seems strange. In 1.2.7, my fans were permanently going full speed. Maybe 1.2.7 was more crap than I realised.
This is an Intel MBP with 2.4GHz dual core, 4GB RAM, GeForce 8600M GT, OS X 10.5.7. I don't have WA.
