/var/db/BootCaches.playlist 2:no such file or directory appeared after Mavericks update

Hi all,

I have tried to upgrade my iMac 2009 running 10.6.8, 3.06GHZ, 4GB ram machine and hit upon a grey load up screen and nothing more after the update. I have worked back through everything I could find in these forums as the bellow:

1. Completed all of the grey screen advice from Apple bar a full wipe and rebuild, but have left this as the last resort

2. Launched again from back up and reloaded Mavericks only to get the same problem

3. Tried to launch in Safe mode and the computer quits half way through the status bar and will not launch into Safe mode

4. Corrected all disk permissions in Disk Utility

5. Checked my EFI update and am running the latest version

6. Tried resetting the NVRAM but computer will not work from the keyboard shortcuts

7. Run Verbose mode where I could see the problem with loading Bootcache which produces the following script /var/db/BootCaches.playlist 2:no such file or directory

8. Created a carbon copy backup also and am now considering a full wipe

I have updated to Mac Book Airs in the last few weeks, and after the computer auto restarts the program then moves to a new processing screen where it finalises writing script, this point never happened on my iMac and after it restarted it just hung on the grey screen with the Apple logo. It is definitely in the Bootcache problem as this is one of te last processes and matches the amount of time the computer starts working before it heads into the grey hanging screen of death. This is definitely something that mavericks script alters, moves or deletes as I have seen this problem littered across the forums as well as the in ability for Safe mode now to work.

I am back up and running 10.6.8 at current and downloading a new version of Mavericks (more fool me). It could be a drive corruption but am unsure, but the computer s working well on 10.6.8 and has done for a very long time. Has anyone solved this yet, as t s driving me crazy!!!

Any Jedi's out there, I would be most indebted to you!

First command (WITHOUT quotes): "mount -uw /"

Second command (Again, no quotes): "rm /etc/launchd.conf"

Then reboot. Hope this helps!

Thank you for the reply! Unfortunately it didn't. I get the notification:

"No such file directory" (see pic: http://oi60.tinypic.com/2r3xwdh.jpg)

Any idea what I can do to fix it?

Hi everyone !

I have exactly the same answer than Metow34.

I think, that maybe I have to change my hard disk ?

Post a picture of where it stops when you try to boot in verbose mode, not Single User Mode

@gadgetboyj

I've tried to put together a complete as possible overview for you.

First of all, here is a pic of when it stops on verbose mode, after this it goes on to start up: http://i59.tinypic.com/2mfbx9s.jpg

But what's more interesting is the "BUG in process" notification which just can't be good. And also the "Geforce sensors still waiting notification". I've recorded the entire verbose process with my phone. Here is the video:

Thank you for trying to help!

Anyone else got any ideas for the situation I posted above?

After that does the system boot normally? The issue being discussed in this thread was leading to the system never getting past the verbose boot sequence.

And MisterJuniiOr, your photo has disappeared, but if I recall, you were getting multiple Disk I/O Errors. This points to hard disk failure as the machine is having trouble reading from the disk.

Hey,

Yes, the system boots normally after typing reboot. My problem is that when I boot in normal mode (not safe mode) at a certain moment, usually just after the system started up, my screen goes blank in the colour thats mostly present on the screen. Like white with snow leopard background or a light brown with Yosemite standard background. But everything, even gaming, works perfect in Safe mode (just no sound).

I came across this notification at a certain point so I thought maybe that's the problem and fixing this can save me completely. I guess I was wrong.
