MacBook Pro dies during update

[Gregalekker]

Hey everyone,

Last night I initiated the El Capitan update and forgot to plug the power cable in. Rookie move, I know...

So I woke up this morning and tried turning the computer on. Of course it was dead. I thought nothing of it and proceeded to go to work.

Later in the day I tried to actually use the MacBook but when it started up the apple logo appeared with the progress bar, which only progresed a millimeter before some code emerged in the top left hand corner.

I tried a series of reboots. Safe mode wth shift, control + option + r + p, etc. command + s simply got more source to pop up, but in the end nothing seemed to work.

I tried rebooting with recovery. I used command + r. That took me to the reboot screen where I chose to reinstall OS X. Currently it's downloading but the installer log is stuck on "error 420", working its way through some sort of language bug.

I'm not sure what the problem is.

My MacBook is less than a month old. As in I bought it like three weeks ago. It's Early 2015, 13 inch, 16gb ram, i7.

Below you can see the code that emerged when it failed to boot the first time today.

I've organized an appointment with my local Apple Store. Otherwise, any advice?

In your position, best recourse it have Apple reinstall the OS, likely it will be faster and less problem.

Are you trying to install the OS over the current version to keep your files?

If not have you tried the recover setting, then go in to disk utility and wipe the drive clean, then try and brand new clean install?

Have you reset the PRAM prior to trying the recovery install, it should clear out any corrupt files from the failed install and may get you passed the 420 error.

Good luck.

Thanks for the the advice.

Fortunately when I tried installing the OS X a second time it worked. El Capitan is now installed and I didn't lose any data.

Hopefully this helps someone in a similar situation down the line.

Good to hear that you were able to get it back up and running.

looks like the problem is there are too many 'f's in your kernel... try removing some of your memory chips
