Wifi freezes Mountain Lion (especially with Safari it seems)

The only fix I have found is to set your computer to never sleep. It has worked and get me running trouble free for about a week now. I must say this is not optimal for energy use and I wonder if the life of the machine will be shorter because of this. I would downgrade to lion if I wouldn't loose any data. Do we Americans have a ACCC? What is the ACCC?

Hi,

I'd come to the same conclusion thanks to a discussion on the Aussie Mactalk forum and this forum where they were discussing the time Spotlight takes to reindex files. Apparently Spotlight and Time Machine don't "play nicely" when running together.

Even though the original reference was deleted by others - the ACCC is the Australian Competition and Consumer Commission, a Federal Government Agency that determines competition policy as well as investigating breaches such as goods not being of merchantable quality.

Thanks

Another fix to suggest is not use Safari. Currently, I'm using Firefox which seemed to all but elimiate the freezes. There has been one or two freezes but much less frequently than when I used Safari. It seems the problem is coming from two ends... Safari and the OS X is having issues talking to each other...

I have the same problem. I barely have anything installed; not Transmit, certainly. I only use Safari for browsing.

there is a much worse problem, I've upgraded 1 MacBook 5,2 and a pro, both

have never had so much as a hiccup and now both since going to ml (clean installs, no software)

both hard lock. even worse they still do it even clean installing back to snow lep. all

Diags say all is fine, I even replaced harddrive and memory but still

the same problem. I know people will say " not possible " but I'm

sure ML has broken the hardware some how. as. programer I know

this is possible. I will not believe I just happened to have 2 macs

go bad just as I switched to ML. if apple doesn't fess up and fix this I

will build my own macs and they will no longer get my money

I wonder if anyone still seeing this thread? I tried upgrading my 2009 Mac Pro to Mountain Lion. Had upgrade issues, and couldn't continue. Was having similar problems as everyone else here. Screen saver turns on, after a while monitor shuts off, and computer goes to sleep. I touch any key to wake the computer, and I have a screen that says I must restart my computer. Reboots, gives me a bug report. I am on wifi, but not getting the exact same thing. When I wake my computer, I just have the screen that says I must restart. No spinning beach balls, no freezing.

I made a lion install thumb drive, wiped my drive clean, reinstalled Lion, and chose to copy all settings and programs from my time machine. Still have same issue in lion. I don't know what Transmit is, is this something that comes standard with Mac's? Not sure what to check to fix this issue. I will try some of the solutions here, and if not, ill hard wire the computer til I can figure it out further.

Our problem ended up being a hardware failure in the 2008 iMac. The quote for repair was a couple of hundred more than buying a new computer. So we bought one of the last mid 2011 iMac's with a Superdrive installed. The new iMacs look nice but as the Superdrive is extra and there are questions about the heat loadings in iMacs causing board failures anyway - the mid 2011 worked for us.
