Apple Event: May 7th at 7 am PT

Looks like no one’s replied in a while. To start the conversation again, simply ask a new question.

My MacBook Pro 15-inch crashes upon startup.

Hey guys. I'm having huge problems!!!! Please prepaid to me ASAP!! I need this computer to work otherwise I'm screwed for middle schools ( it needs to be fixed by Monday this week )

My Mac wont boot. Every time it boots it will crash.

This is the boot in verbosboot or however you call it, is on YouTube with this link here:

I recorded it just so you know how long it boots. This is how long it takes for it to hang on the apple logo with a spinning wheel. At the end of the log when it shuts down. The wheel freezes. Then the Mac reboots and says it restarted because of a problem. Or as I call it kernel panic.

Here are the fixes I have tried:

1. Reinstall OS X: tried it. Still nothing changed... :(

2. Reset pram and VRAM: nothing changed :(

3. Safe mode: does the exact same thing. :(

4. Verify the disk in recovery mode with disk utility: says its fine :(

Specs:

This is a mid 2012 15-inch MacBook Pro

8 core intel processor

8GB installed RAM

500GB hard drive / RPM: Unknown

Age: 6 months from purchase

OS: OS X 10.8.2 / Mountain Lion AKA latest version of OSX

Notes:

I don't know if it was cause I plugged in a new external hard drive but it does not seems so. But however it has been put to sleep instead of being shut down for about 2 weeks ( why? Cause I'm on holidays. And too lazy to shut it down and than wait 2 min in the morning to play games )

Was perfectly fine before I stop shutting it down...

It sounds like you have solved your problem, then. There is no point in trying to identify which files were damaged. Something in that system was corrupt, that's certain, although its a bit of a puzzle why reinstalling the system on top of the damaged system didn't fix it. In any case, just copy your data into the new, fresh system (preferably without using Migration Assistant or Setup Assistant... do the job manually, since you don't know what else might have been corrupt, like settings files in your user account and whatnot). Then delete the corrupt system from the external drive and use that for backups. You'll want to be vigilant about backups, as it's still entirely possible that the internal hard drive is failing and files will continue to become corrupt.

Belive it I not. I thought if that exact idea in my shower this morning.

So I'm current ly doing that.

Here is a status of the drives:

External hard drive:

Partition 1 - fresh Mac OS X for moving files

Partition 2 - old and broken Mac OS X

On the to do list:

Hard drive:

Partition 1 - fresh OS X

I plan to move te following files off the external hard drive and into the laptop hard drive:

Applications

Library

System

Users

And a pointless license agreement

Solution found!

First of all I did was move the files on the HD onto the external hard drive.

Then I made 2 partitions on the external hard drive.

One partition has the OS.

On the other partition you go into Internet recovery and reinstall OS X on the 2nd partition.

Then I installed a brand new OS X on the HD in the laptop via Internet recover too and then moved the following files in the old backup if the hard drive into the fresh OS X:

Applications

Library

System

Users

Now it won't work yet.

You need to then reopen Internet recovery. And then click on reinstall OS X and do it to the HD on the laptop. Then boom. It's working. All it needs now is a Couple of updates and you ready to work!

To get into Internet recovery:

When the system is off. Press the power button.

As soon as you hear the startup chime or see the screen turn on, hold down te following keys until a gloab appears on the screen:

Command ( apple ) + option ( alt ) + r

Then you let it load the Internet recovery files off the internet and boom you in Internet recovery.

If you read this disscussion and have problems at startup, do this exactly IF. Your problem is mostly completely similar to my problem.

To make sure. Read the whole first post at the top to make sure this is the right solution.

crazy "solution" and inefficient. Let Thomas explain why if he has the time for it.

Jan 7, 2013 12:46 AM in response to Lexiepex

Well as crazy as it sounds. As long as it fixed it. I don't need any explaining. But if you insist. Give him some time.

Anyway I have to go. Be back later

I've got to agree with Lex. Why would you bother copying portions of the damaged system back onto the fresh system, then reinstall a second time on top of that? That's just ridiculous. Like you're trying to create potential problems and extra work for yourself. If it works fine after what you did, it's pure luck!

The proper thing to do would have been:

1) Install fresh new system

2) Reconfigure settings the way you like

3) Copy data only (no settings files, no applications or application data and most definitely no parts of the old system) to the new system

4) Reinstall applications from scratch

Actually I found out the tis fix may bring it back into working but however it made os x HIGHLY unstable...

But I have an idea to redo things mannually

Jan 7, 2013 10:12 AM in response to thomas_r.

that's what i plan to do today.

Jan 7, 2013 1:05 PM in response to alexanderfromcalgary

Ok guys lucky me! I found the backups sparse bundle on my time capsule. It backed up the day before I left for holidays and before whatever happened occured. But although thanks for all of your suggestions and help 🙂

But I still want to figure out what the **** happened during the holidays that just complete;y broke my laptop. and for sure why reinstalling OS X didn't fix it..
