Re: HighPointRR.kext not loading automatically on startup...
Two suggestions might help... (I thought I included them in my mini-howto above, so forgive me if I actually skipped them...)
1. Kernel Extensions need to be owned by root:wheel, or else they won't load. In Terminal, you should be able to do this by:
sudo chown -R root:wheel /Library/Extensions/HighPointRR.kext
(This needs to be recursive since the 'HighPoint.kext' "file" in finder is actually a package of resources as well as the actual extension binary, similar to .app applications.)
2. The Kernel Extensions cache needs to be forcibly rebuilt to include the older HighPointRR.kext extension. To do this, you should:
- Reboot into your Recovery Partition (or if you have multiple boot partitions, boot into one other than the partition that you're going to try to rebuild the kext cache...)
- Go into Terminal
- Execute the following commands:
- sudo touch /Volumes/<the_target_volume_name>/System/Libraries/Extensions
- sudo touch /Volumes/<the_target_volume_name>/Libraries/Extensions
- sudo kextcache -update-volume /Volumes/<the_target_volume_name>
After this is done, reboot back into the partition that you are trying to get to autoload the HighPointRR.kext kernel extension. During the boot process, it should rebuild the kernel extensions cache and include the HighPointRR.kext in the process so that it will autoload during subsequent boots.
If you don't have a Recovery Partition on your disk for some reason, you can boot with one of the OS X Installer disks, back out of the installer, go into the utiliities menu, and launch Terminal from there. Last resort, you might be able to just do this while booted into the partition that you're trying to fix if you have no other options... (Using the 'kextcache' command I think should force this to work on the current/active OS partition? I know that touching the ../Libraries/Extensions directories on a disk that isn't the current/active OS disk can cause the cache rebuild without the kextcache step, since I did this accidentally once when I was going through the same thing...)
Hope that helps, and best of luck.
