Wifi freezes Mountain Lion (especially with Safari it seems)

I too have been having this problem in additiion to the wake up problem after 10 minutes. It seems to also occur when switching WIFI networks, although not every time. At work we have several WIFI networks and I often need to switch to another network from the wifi menu. Sometimes the switch fails the beachball comes up, and my mail, safari and other apps stop responding in the force quit menu. I usually have to reboot from that point. I have disabled Transmit Menu as suggested by others since it sounds promising.

After testing all morning, removing Transmit also works much better for me. I can now switch networks over and over without any problems. Only change was removing Transmit Menu.

Just putting in my notice as well. Seems to be the same issue...

• Mac goes to sleep with apps running

usual apps safari, mail, messages, skype, ical, *sometimes transmit but I never used the menu item*

• Mac wakes up... instantly starts to show beachball, wifi menu item apears to be looking for the network

safari, mail, and any other netowrk app all lock up force quiting does not help

finally gets to the point I just have to force the machine to reboot

This is very annoying and unbecoming of a UNIX based OS I'm actaully shocked you can get it to lock up this bad.

Transmit does not need to be running, only the transmit menu icon needs to be checked in prefs and therefore showing on the menu bar.

The change on my and my friends MBP's have been dramatic and 100% OK since unchecking the pref option two days ago.

coming to think of it, my MBP won;t wake up after a longer sleep by clicking any key but the Esc-key, or the Magic mouse. Not even touching/clicking the mousepad or spacebar wake it.

Deleting Transmit, although solving the freeze problem, does not help this, minor, issue.

Anyone with the same experience?

I just had this problem with my new Retina MacBook Pro. I haven't noticed it before, but I'm not usually running Transmit (I just use the FTP connection in Coda). Yesterday I wanted to do some heavy lifting in FTP so I launched Transmit and left it open. I put my computer to sleep for the night, started up this morning, and in investigating what might have happened I found this thread.

Points quite a bit to Transmit being the problem.

On my machine the Transmit menu item is disabled.

Try enabling Transmit Disk, shutting down Transmit, then open it again and disable it. That seems to have fixed the issue for me as I was locking up and didn't have Transmit Disk enabled either.

That's worth a shot. Thank you. I enabled Transmit Disk, quit the program (leaving the menu item open), relaunched, and then disabled Transmit Disk again. I'll report back if this seems to have resolved the issue for me (and I imagine Panic will be along at some point with a fix too).

24 hours since I removed the Transmit Menu and I have not had a single issue. This includes many times letting my computer sleep & wakeup, and many network switches. Problem points squarely at Transmit.

I disabled the Transmit menu icon and it didn't work for me. My Mac still crashes on wakeup from sleep with a spinning beachball and an exclamation point over the WiFi symbol in the menu bar. Only way I've found to prevent the crash is to completely disable sleep altogether.

I have also had no luck with disabling the transmit menu icon. The only thing that seems to work for me is avoiding the use of Transmit till its fixed.. :/

If disabling the Transmit in the menu bar didn't help, I would suggest disabling any other programs that are active in the menu bar. I had the same issue, and once I disabled Transmit my system worked perfectly.

I have already been in contact with Panic, Inc. and they sent me an email back and said that they'll look into the issue.

stephenskelly: You can still use Transmit even though it's not in the menu bar. Your system will not freeze up.

It doesnt freeze up while im using transmit, just if any of my machines go to sleep (for more than 10 minutes) with transmit open, then, when I wake the freeze will happen. I have took transmit icon out of the menu bar, and its not made any difference, which seems odd as it seems to have worked for may others. Im not too bothered though, im coping without it for now, just using alternative ftp client for now.

Ive spoke with apple about it, and they have all my specific crash reports, both with and without transmit in the menu bar. It definitely only seems to be an issue for me when my machine is put to sleep while transmit is running, ive even started my computer up with transmit as the only active application and its still freezing after sleep. When I dont use/open transmit i dont have any issues, so for now thats the solution that works for me.

I've never used the Transmit menu item ever. I have te same problem. If I leave Transmit running (no menu item). Let the machine sleep with Transmit running, come back later wake it up, same problem, beach ball force restart.

Its 100 % related to Transmit but not just the menu item.

I had to make sure I quit Transmit after using it.
