Kernel panic from iPhone USB tethering

Apple claims to have fixed the problem with the latest iPhone OS:

The fix seems to work. I tethered via USB and there was no crash. Phew...

I haven't tryed USB tethering to my MB yet

but on my 64bit windows desktop, it crashes mobile device support every time i plug in my iphone so i can't even sync it.

i fixed it but i had to restore the os

Try turning Personal Hotspot off before connecting the iPhone to the MB (or put the iPhone into flight mode).

I maintain my iPhone with an iMac and so had not encountered the problem of trying to update the iPhone OS with a Macbook that keeps crashing.

Of course, if you only have internet access from the MB by tethering the iPhone then you will not be able to run iTunes to update the iPhone OS unless you use wi-fi or bluetooth tethering instead of USB tethering.

I've just started experiencing the same issue with my brand new 15" MBP. It panicked on me three times last night while I was tethering with my iPhone 4. That didn't happen with the MBP I had before (the last generation, just before the Thunderbolt / Quad Core). The error dump looks very like the rest of the ones listed here - a networking / browser related issue.

This worries me quite a bit because I just had to replace my last MBP because it was giving me kernal panics daily because of a fault in the Nvidia chip. Sigh. I feel like the unluckiest Mac user in the world!

The bug isn't fixed in 4.3.2, I just got the KP with 4.3.2 and 10.6.7...

Same KP issue here on a brand new MBP 2011 and an iPhone 3G syncing over USB. Someone else mentioned running Virtual PC and MacFuse. It might be worth mentioning that I also have VMware (with MacFuse) on my machine, which is otherwise pretty clean. I'll try the 32 bit boot tip and hope for the best.

if your system normaly boots up in 64 bit mode (which it seems it does) you need to restart your computer and press 2 and 3 simeltinuosuly to boot up in 32 bit mode

it didn't solve the issue yet!

after reading all posts in this discussion and updating to latest ios

I tried to tether my

iPhone {ios 4.3.2 3GS ; Sep2009; MC131J; Firmware:05.16.02 (newest firm ware available Today )}

's Internet Connection with my

Macbook Pro {Mac OS 10.6.7(most updated version); march 2011; 13"; 2.3 GHz Intel Core i5; 4GB 1333 MHZ RAM, and most recent iTunes 10.2.2 (12)}

via USB and unfortunately got kernel panic (You need to restart your computer. Hold down the Power button...) again.

it seems there is no problem with USB tethering when when you use it in windows 7 installed through BootCamp.

and Bluetooth Tethering is still unstable and keep dropping every now and then both in Mac Os and Windows.

so at this point; apples solution here: http://support.apple.com/kb/TS3728 (thanks to Michael Paine) doesn't realy Help.

so it seems the only solution (Temproraily) for the problem could be using your Mac in 32bit Kernel Mode (look at this: http://support.apple.com/kb/HT3773?viewlocale=en_US) it works without any problem and most of general users don't feel the diffrence.

Still panicking on 2 different machines with updated iOS...... FIX THIS PLEASE!!!!

After further tests I encountered a crash with my MBP. I used Firefox with no problems for 15 minutes, then Safari for 10 minutes. Then I started Apple Mail and the MBP crashed in less than a minute.

This confirms ios 4.3.2 does not fix the problem.

The problem has become intermittent for me. After the crash I reported earlier I repaired permissions and then started Apple Mail. It reported the Mail data was corrupt and that I needed to restart Mail. I did this - it rebuilt the data and started normally. I have now had the MBP tethered for a hour with no crash.

I have been thering my 2011 Macbook Pro to my iPhone 3GS all week using a bluetooth connection, which has worked fine without any issues.

Today I tried tethering to my iPhone again, but this time using a USB connection.

Over a period of about 20minutes the Macbook has 3 kernal panics crashing completely out and needing a restart each time.

This issue only occurs when tethering my iPhones 3G connection to my macbook via a USB connection.

iPhone 3GS 16GB (running iOS 4.3.2)

MacBook Pro 2011 (13inch 2.2GHz i5 / 4GB RAM)

Mac OS X 10.6.7

Still experiencing KP's even after latest iOS update on my iphone 3GS (currently running 4.3.2).

I'd say that the issue hasn't been solved...
