Q: OS X EL Capitan crashes and shuts down my computer 2-3 times a day

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.

Me to. Having problem shut down (force shutdown) without any prior notice when come back from open lid.

As what I observe, I'm using XAMPP to create a localhost in my laptop. Shutting down this program before when sleep by close the lid does not end with auto shut down. Do you have same application installed in your Mac?

Previously on Yosimite, there is no problem. Only after I install El Capitan through Apps Store update.

Yes, I am having the same problem as you described.

My Mac shuts down without any notice since I upgraded to El Capitan.

It ruins the user experience of Mac!!

I closed and shut down all XAMPP related program. Turn of my mac by closed the lid.

Unfortunately, this weird behavior still happen. It freeze a couple of second after recover from sleep before totally shut down and reboot automatically.

Totally ruin user experience. But I still didn't try to do fresh reinstall since my Mac is actively used. Reinstalling everything is not the best solution at this moment.

+1. Me too.

Check Applications -> Utilities -> Console logs for any panic or error messages. Please also provide your Mac year/model information?

Check this out.

Most likely you need an updated driver for the "Nano Transceiver".

Yep sadly after so many crashes lost count have to say El Capitan is the worst buggy OS from AAPL ever. Don't know how many times sent a crash report to AAPL, guess the fact they seem, without the courtesy of informing their customers or withdrawing the update until it works, to be on a Mark 3 or thereabouts El Capitan beta to try to redress the issues so many people seem to be having. Very disappointing especially as my backup computer still on Snow Leopard, which AAPL by not updating security seem to be forcing all quite usable old Intel computers to the junkyard, or having to go to an alternative competitor such as Google or Firefox. Completely crazy situation.

Not true.

We are here at the hospital, where there are lots of sick people. So there must be an epidemic.

Every piece of software has bugs. So does El Capitan.

There are millions of users of El Capitan, and most of them have had no issues.

Most of the problems boil down to one of a few things: hardware that requires an updated driver; old software that is not compatible; or the user having installed crapware like "cleaners", or using antivirus that are not needed and end up crippling their systems.

Saying it is crap does not help anyone. Giving detailed info about one's problems can let others help out and usually get them resolved.

How to find which hardware cause the problem from the panic report?

same question

Did you check the nano transceiver I mentioned?

Yes, it does have an old driver. Unfortunately it does not have the driver that supports El Capitan.

I unplugged it and want to see how it goes.
