MacBook Pro 2011 USB Tethering Cause of Kernal Crash READ

I went back to apple and got a replacement anyway just in case it's a hardware issue. With my new Macbook Pro, I haven't installed any 3rd party software and browsed the internet for 3 days using my regular Wifi at home with no issues at all. Today, I connected my MacBook Pro to my iphone for internet tethering and BAM kernel crash within 5 minutes with standard out-of-the-box software. This is a software/firmware issue and Apple needs to send us all a new update.. In the meantime, if your having this similar issue please post your responses to the following questions lets try to further narrow down this problem:

1)It could be specifically an Iphone tethering issue not all smartphones possibly due to not being the most current iphone software version.
2)Are you using a jailbroken app (MyWi) to tether or the tethering approved and paid for by your service provider? (Does it happen via usb or wifi also?)
3)Is there a way to downgrade a new MacBook Pro O.S.? Maybe this software version is causing it (10.6.6) Might or might not fix the problem, but worth a shot if other MacBooks have this issue?

If we can all post detailed answers to these questions, we might be able to pinpoint exactly what is causing it and also to help apple produce a proper fix.

I'll answer first:

1) Iphone 4 tethering
Iphone version: 4.0.1 (8A306)
2)Tethering thru MyWi v4.52.2 via usb or wifi both crash MBP
3)MBP 2011 - 17'
i7 2.2 GHz / 8 GB RAM
Mac OS X (10.6.6)

MacBook Pro 2011 17', Mac OS X (10.6.6), I7 2.2 GHz / 8 GB RAM

Having the same problem with MBP Early 2011, the problem is probably related to the Apple USB driver, we need to wait for a fix. Come on Apple, first the flickering displays then the freezes and now the KPs with tethering!

Same problem here with iPhone 3g + MBP 13" i7

Anyone tried with the 4.3.1 IOS update which has just been released? Downloading now but i have a crummy connection.

Downloading now, thank you. But there is no mention about our problem. I think this cannot solve...

Hi!

I have the same problem. I have updated my MBP with 10.6.7 and my iPhone 3GS with 4.3. But it still doesn't fix the problem!

No problem tethering through BT though.

I hope Apple fix this problem ASAP.

This is the solution to all our problem (until Apple fixes it).

First deactivate Open Network Preferences. If you see iPhone (Not Connected) on the left panel, Disconnect it.

This will still allow you to connect your iPhone to charge and sync with iTunes without causing a hang.

Next go to Settings in your iPhone and On the Personal Hotspot for iPhone 4 (or Internet Tethering for iPhone 3GS). But first set up a Wi-Fi and Bluetooth connection with your MBP.

Your tethering with iPhone will now use Wi-Fi or Bluetooth and you won't have any hang henceforth.

You can continue to plug in your USB cable to charge (Wi-Fi and Bluetooth takes up a lot of battery!) and sync with iTunes.

Wonder why my calls to Apple Support were unable to give me this work-around.

This is happening to me on both my 2010 Mac Mini and my 2011 MacBook Pro with my iPhone 4.

Is everybody with the kernel panic issue using 64-bit boot mode?

I found the suggestion somewhere that the problem disappears in 32-bit boot mode.

There is only an incremental advantage to 64-bit boot, so I will revert to 32-bit boot and try USB tethering after I perform my mission critical tasks this morning.

Mar 28, 2011 5:51 AM in response to George Knighton

Yes, please test it out on 32-bit mode and let us know if you still get hangs.

Thanks

Mar 28, 2011 6:13 AM in response to Philip_Chan

Big difference.

I've been on 32-bit mode and tethered for quite some time now, under circumstances that used to always produce panics.

Nothing, yet. This is much, much better!

Just to inform, I have the same issue here:
MBP 2011, 13, 2,7Ghz + iPhone 3G (both up to date).

Mar 29, 2011 6:17 AM in response to NiloB

Just want to verify that I have still had zero crashes since switching to 32-bit boot mode.

Mar 29, 2011 11:57 AM in response to kingwow3

I somehow missed this post when I searched, and then created my own. I'm having the exact same problem. Using iPhone 4 with MBP 15" 2.3 quad core i7.
Only causes Kernel Panics when connected via USB. Wifi and bluetooth are fine.
Replaced RAM, clean installed OS X, reset PRAM and SMC. I've done it all, still crashes.
