Yosemite Freezing at Boot

[Jithin.C.V]

Hi -

I tried booting with your suggestion: dart=0 nv_disable=1 -f -v". it boots fine, no freezing. What to do now?

This is an upgrade from Mavericks. Right ??

If Yes, my suggestion is, just backup the important datas and do a fresh installation of Yosemite after repartitioning the disk.

there is no other viable solution for fix? why would i need to repartition?

If you ready to go with further troubleshooting then,

1. If the BIOS is not running with latest version, then update it to the latest available version.
2. Post your org.chameleon.boot.plist

Which version of OS X you are running now?? Which version of MultiBeast you had used?

why would i need to repartition?

So that everything will wipe out.

How do I post my org.chameleon.boot.plist ? I am running 10.10.3, with multibeast 7.3

You can attach the file while posting replay.

The file will be present under /Extra folder of your MultiBeast/OS X target partition.

Make the below changes,

<key>Kernel Flags</key>
<string>kext-dev-mode=1 dart=0</string>

<key>UseKernelCache</key>
<string>No</string>

<key>IGPEnabler</key>
<string>No</string>

Add these line too,
<key>GraphicsEnabler</key>
<string>No</string>

Save the file and check booting again.

If same issue, then boot with "nv_disable=1 -v". Then download and install web driver for your OS X version. Then try booting with "nvda_drv=1 -v"

So I ran your suggestion and it looks like it restarted/booted without freezing! Good news.. However, when at the Apple Logo it takes 5x longer to get into start up than normal?? When Booting initially, I got the message at the top left corner in a black screen "Errors encountered while starting up the computer. Pausing 5 seconds...." What changes you suggested caused this? would you happen to know? Im assuming this may be a graphics related issue that causes these issues? I also lost my audio after doing these changes... do I need to repair disk permissions after making changes following the reboot? Thank you so much for your help..!

edit: After those changes bootup gets to bypass the normal freeze issue I had, but freezes after I log in my user. It freezes after the first 5 seconds now.. should i try the nv_disable=1 -v flag?

Any idea what is the cause of the message now "Errors encountered while starting up the computer. Pausing 5 seconds...." ? I get this at start up
