MAC crashes and reboots - USB driver failure?

This exact same thing started to happen to me recently. On the Sierra Public Beta. I don't know why.

Please post the whole panic report. I know it's long.

Please read this whole message before doing anything.

This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.

The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.

Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem.

Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Ask for further instructions.

Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.

The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.

Test while in safe mode. Same problem?

After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

If you have access to another Mac running El Capitan, please connect those devices to it and see whether the same thing happens.

SAme problem here

Mine just started crashing after being ok for a week after install. Mine works ok till I go to goggle news on Safari and click out to get more info on an article. It then crashes to a screen to restart with a panic code kernel listed.

If I try to use Firefox, it freezes the screen instead of shutting down.

hope we have an upgrade soon.

Told my friends not to install.

Reinstalled system but did't help.

I'Ve found a post where somebody were saying to repair disk permission from recovery mode and resitall osx from there... I' ve done the repair permission thing and now i'am at the resitallin process, fingers crossed...

Re: OS X EL Capitan crashes and shuts down my computer 2-3 times a dayin response to dhenri99

Reinstalling OS X Without Erasing the Drive

Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.

Reinstalling OS X Without Erasing the Drive

Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.

When the recovery menu appears select Disk Utility and press the Continue button. After Disk Utility loads select the Macintosh HD entry from the the left side list. Click on the First Aid tab, then click on the Repair Disk button. If Disk Utility reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit Disk Utility and return to the main menu.

Reinstall OS X: Select Reinstall OS X and click on the Continue button.

Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

Reply

I am having the exact same problem and have not solved it yet. I'm replying here in case anyone has discovered anything; I would like to be notified.

I am getting occasional (about once per day) random shutdowns, and when I reboot, I get an error log very similar to the one posted above. I'll post mine below, just in case there are additional clues.

Interestingly, if I boot into safe mode, I don't get any further errors upon boot up. (I can't do any real work in safe mode, so I can't verify if the shutdowns still happen.) Also, if I disconnect all USB devices except for the USB mouse and keyboard, the errors also go away.

If anyone has any clues, please reply.

Try uninstalling the above using the Developer's uninstall instructions. I would start with Soundflower and Paceeap.

Thanks. I will try that. Out of curiosity, what makes you finger those five as possible culprits? They're not mentioned at the top of the crashlog, which *seems* to have something to do with "airportd" or one of these three:

Amazingly, I was finally able to solve this issue by reinstalling El Capitan from the App Store.

After reinstalling, it no longer gives me that error log on boot up, and I have not had any more spontaneous shutdowns. Phew!
