    Downloaded Mavericks no problem on my 15" MBPr, now the wifi icon on top is grey with a exclamation mark in it. Wifi is working though. Is this how it should be now?

    I got that, too, along with a self-assigned IP address. It took longer than usual for DHCP to work its magic. Seems like a Mavericks issue.

    Is your's a 15" MBPr?

    I have installed Mavericks on 2 x 09 iMacs, and a 13" MBPr and my 15" MPr now. And this is only happening on my 15" MBPr?

    Ever since I installed Mavericks my wifi drops about every 5 minutes. I have to turn off wifi and then back on to get it to reconnect. I've tried everything, unplugging my router, my modem (both cables and power), you name it.

    Mavericks is also eating up every molecule of RAM.

    Mavericks is the Mac Vista. Really wish I didn't install.

    Mavericks "using all your ram" is normal. It uses all available ram for cache, and the new memory compression feature allows it to compress ram on the fly to avoid paging out to swap. I only have 4 gigs of ram and have found mavericks significantly faster than ML.

    If I see one more post about "mavericks using all my ram" i'm going to punch a baby :p

    When you look at the mavericks task manager's energy tab, take a look at the values for "app cache" and "file cache". Add these two up, the number you get you can safely consider "free ram".

    Also note the memory pressure graph. You only need to worry if this graph is showing very high memory pressure.
