Can't get Lion into x64 - Extensions?

[lloydowen]

Hey guys, It's been a while since I have posted here. But I installed Lion quite some time ago now, I used the guide on TonyMac but I was wandering around my system profiler and I realised that my system is not actually running in 64 bit. I further inspected this and noticed that '[url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url]' in fact added the 'arch=i386' string into the kernel string. Why has it done that?

 

Anyway I removed it and my system would not boot, so again I booted back into 32 bit mode to see what was happening and I noticed in System Profiler that there are a few extensions all end in '6.0' were not indeed running in 64 bit mode.

 

 

They look pretty important to me... But I booted into my backup drive which is my Snow Leopard drive (Running in 64bit) and those extensions do not appear to be there. I don't want to delete them because they seem important. Somebody shed some light? Im sure someone has some info on this, I have a vanilla system too, no modified kernels and the only extension I use is VoodooHDA.

 

Here's a picture attached of the extensions Im on about.

 

Oh By the way They all follow the Path

/System/Library/Extensions/System.kext/Plugins/

I would start by adding your system profile in your signature, someone might know whats the reasons for it.

Just added to signature, Please help guys!!! Also having random kernel panics - Annoying!

 

Never had these problems, but I bought a new hard drive and had to reinstall, was working perfect before but can't remember what I done to install it!

They probably do that to ensure compatibility with more hardware. You would have to ask at the Tonymac forums if you want to know for sure.

 

If you delete system.kext or any of the plugins inside it you will not be able to boot in 64-bit mode or 32-bit mode. So just leave those alone.

It's perfectly normal to not have the same kernel extension version numbers on Snow Leopard and Lion! The System.kext plugins do load on Snow Leopard, it's just that they are named differently. Check System profiler and look more closely, OS X will not boot at all without System.kext.
