Didn't they include 802.11ac support in the very first 10.8.4 beta?

Thank you

Sorry about that, I had typed it right uploading the image so just a small lapse of brain function I think!

Do you use your Mac for real work, or just for startup/shutdown benchmarks?

teknishn · May 15, 2013

I can't remember the last time I shut down my Mac. Lol

I immediately noticed improvements in Wi-Fi with my current gen Airport Extreme Base Station. My current gen Mac Pro had some difficulties with the 5GHz network, transmit rates weren't as good as my MacBook Air running 10.8.4 in the same area of my home. Now it's getting 300, consistently. My local Wi-Fi has improved considerably.

safari 6.0.5 was in the last build with build number 8536.30.1. did it change?

Nope, same build number in 12E52 so it's not snappier!

What's the "DFS" ( 5Ghz) mean ?

The DFS part. Not the 5Ghz part.

Also known as "Automatic" in the Airport Utility. It just changes the WLAN channels as required to reduce congestion in the air waves.

The shutdown times for me are less about it being a problem and more about it being confusingly not fixed yet. I've had the exact same problem since Lion on my other machine (1st gen MacBook Air), but I doubt I would have noticed if I wasn't actively trying to see how much I could delete without breaking Lion and running it in verbose mode all the time (for fun of course).

Fortunately I finally have a real machine, and now I can entertain myself beyond browsing the internet and listening to the fans go off.

dastinger · May 15, 2013

FFS, let's not start a shut down vs sleep argument again. You never ever in your life shut down your Mac? Good for you! That doesn't mean shutdown times should be that long. Period!

Yes. I'm more concerned about who is steering the OSX coding boat right now than I am about the bug itself. It's quite telling on many counts.

My Mac shuts down in seconds. I don't know what programs you guys run, but I go heavy Final Cut Pro and Logic and my iMac 2011 running the latest software with a SSD has almost instant shutdown.
