Installed El Capitan beta 4 and no able to log in

Hi cheeky,

The first step with that kind of boot error is to perform SMC and NVRAM resets:

NVRAM Reset

1. Shut down the computer.
2. Hold down Command, Option (left side), P and R keys while you switch on and continue holding them until you hear the restart sound a second time.

SMC Reset:

1. Shut down the computer.
2. Plug in the MagSafe power adapter to a power source and to your computer.
3. On the built-in keyboard, press the (left side) Shift, Control, and Option keys and the power button at the same time.
4. Release all the keys and the power button at the same time.
5. Press the power button to turn on the computer.

It may be worth doing them more than once - one person I was discussing a boot fail after update to PB 4 with had to restart 5 times with NVRAM reset before the issue was resolved.

Let me know how you get on.. there are a couple of other possible causes too.

Max.

To see about another common cause of your issue, can you restart in Safe Mode (hold shift from after you switch on your Mac until you see the progress bar)?

After doing the PB 4 upgrade, my MacBoo Air hangs at the Apple logo during normal booting. I can boot and log-in in safe mode (tried it sevelat times) but not in regular mode. I already did the NVRAM reset and the SMC reset several times not that did not help. I called Apple support but they won't help Beta users. Any other suggestions?

Hi Pierre,

I'm happy to try to help, but could you start your own thread as it becomes complicated trying to help two people in the same thread if they turn out to have different underlying issues (there seem to be at least 4 underlying issues that people have had with PB4 - so far only 2 or 3 have been identified).

Thanks,

Max.

I tried restarting in safe mode and it came up with a progress bar but then cut to a black screen with a lot of code on the left. It then shut down and showed a screen saying, your computer shut down because of a problem, press any key to restart. Now I can't' restart in safe mode. Have restarted several times with NVRAM and SMC but no difference

These forums are about to be closed (OS X 10.11 Beta Forum Closing)

I should point out that I'm not affiliated with Apple in any way, but if you would like to request personal help, please contact me on MacMax108@gmail.com

Well, I have to go for a few hours now, I'll have a look at the output when I get back.

I did all of that in terminal but they all showed that "no such file or directory" message and also involumes it didn't show Macintosh HD it just showed OS X Base System and .Trashes. Given I never changed the name i'm not sure how that could have changed. When i run disk utility it shows that OS X Base System under external disk images in "Apple disk image Media"? not is relevant but it also shows several untitled drives underneath that aswell. It shows Macintosh HD under internal.

Actually after i went into disk utility and unlocked the Macintosh HD it now shows it in Volumes but no change to the output of the last three commands.

I do not have Virtual Box installed although i do have VMware Fusion. not sure if that helps

Hi, sometimes the only way to find the culprit causing the crash (9/10 times a kext) is to boot in Verbose mode (cmd+V).

If you can do that and take a picture after it has stopped then we'll know more. There's no way to post an image directly to the site so the only way is to upload to an image hoster and remove the http ://www. from the link and then click the A above (otherwise it will automatically go into moderation for many days because of the link to a non-Apple domain)

Alternatively, you can use Recovery Mode to re-install El Capitan. It will put you back to Beta 1 but will leave your data intact.

You could then install back up through to Beta 4 again. Or you could wait for Beta 5, which I would guess will be a combo, allowing you to skip Beta 4 altogether.

I have tried that and it doesn't seem to stop just repeats the same thing over and over after a while. and it is MB air and won't connect to wifi and has no ethernet port so can't connect to internet to re install El Capitan.

Okay. Some more questions then:

• If you connect your Time Machine Backup and hold alt while booting, does it show the backup drive in the list of bootable drives?
• What is the message that repeats when you try to resinstall OS X from Recovery Mode.

Also it looks like your El Capitan partition is not mounting the encrypted El Capitan partition. From Recovery mode you should be able to "Restore from Time Machine Backup". You might need to erase the El Capitan partition first from Disk Utilities.

Let me know how you get on.
