iatkos 5i not booting after update to 10.5.6
 

I think i must have misunderstood, but i read that iatkos 5i can be updated like a regular mac..so i applied the update from inside the OS, and on reboot, it hangs.

Any ways to make it work or at least rever to 10.5.5 without reinstalling from scratch?

My update attemp to 10.5.6 went wrong too. I could restore my system with the installation dvd using my timemachine backup. After reinstalling chameleon bootloader everything is working like before.

Good luck!

what if i dont have any backups on timemachine?

Tell us where it hangs. If your getting a blank screen with Apple logo use -v on boot and tell us where it stops.

Place your specs in your signature will help us too.

it hanged once after mounting the other hard disks, and once i dont remember where...

anyway meanwhile i reinstalled it and i will keep it to 10.5.5 .

also i have changed my video card since i was on VESA with my GTX 280. Now im on a 7200 GS 128 RAM , im not on vesa anymore, but one of the main reasons for installing mac, LOGIC (audio application) still detectes 0 MB VRAM.

i have chosen at installation the Titan drivers for nvidia and i might have chose the NVinject also (im not sure though). In System Profiler at Graphics there are 128 MB Vram, and at ROM says NVinject 0.2.1 ...maybe anyone can help me with this ? :)

Thanks

You don't want to select multiple graphics drivers.

Lets try this for your graphics card.

1. Go to http://nvinject.free.fr/ and download Latest_NVinject.0.2.1.zip

2. Go to the /System/Library/Extensions folder and remove existing graphic's kexts. (NVinject, NVkush, NVdarwin & Titan) You may want to back them up to a folder on your desktop or a USB thumb drive.

3. Unzip the file you downloaded and drop NVinject.kext into the /System/Library/Extensions folder.

4. Open Terminal and type the following to correct permissions to the Extensions folder. 5. Then type the following to repair permissions to your entire drive. 6. Then type the following to remove the Extensions.mkext cache file to force OSX to rebuild it with the new NVinject you installed. 7. Reboot with -v -f

Check to see if QE/CI is supported.

thanks a bunch im about to try it now, a quick question before: is there any chance my system wont boot aftewards and i will have to do a new install?

on the " sudo chmod -R 755 /System/Library/Extensions && chown -R root:wheel /System/Library/Extensions " command , i get :Operation not permitted ...is it normal ?

With graphics drivers generally not. You could remove all of them and restart and will get default 1024x768 no QE/CI. I generally tell people when the do an install to not even select any graphics options as selecting the wrong option or multiple options can cause problems. I recommend that you back these files up to your desktop or a thumb drive as good practice. You may in the future, have to replace kexts and it is a good idea to keep them handy so that if you can't get back into OSX you can replace them in Single User Mode -s to avoid having to do a complete reinstall.

hopefully i wont have to do a full reinstall...

now what do i do with the Operation not permitted ? (post above last post of yours)
