Hi there,
yesterday I finally did the step. I prepared a USB Stick (thanks to http://liondiskmaker.com/) to be able to do a fresh install on my Late2008 Macbook Pro. (I havent done it once in the last 5 years
).
I formated my HDD from the USB stick UI and started the installation. After the first status bar came to an end ("Preparing to install Mavericks") the MacBook restarted and then the dilemma started.
The mac only showed the Apple Logo and afterwards the circle with a line and another wierd icon. I went through lots of steps (SMC reset, CMD+ALT+R+P, CMD+V etc). Nothing helped. Then I decided to redo the whole process again, but even under ALT-Booting the USB drive didnt show up anymore.
In the end I managed to boot an Ubunto Live USB stick to make sure that there is still a working HDD. On the HDD I found a folder called "OS X Installation files". My only possible guess was, that the OSX bootmanager saw that folder and decided, its in the middle of an installation process and therefore wont show me the Mavericks USB drive. So, I deleted that folder -> No difference. I booted again to Ubuntu and deleted the whole partition.
Now the Mavericks USB sticks does show up again if I boot with pressed ALT - but in the moment I choose the USB stick, the same weird icons appear again. By pressing CMD+V (Verbose mode) right after choosing the USB as a boot device, I managed to see the actual error:
"Error loading kernel chache in .IABootFiles".
I checked the USB stick in another mac and the kernelcache is actually available at that location (screenshot). I also already tried to redo that USB stick without any success.
Unfortunately Mountain Lion doesnt seem to be available anymore in the Appstore and I am really running out of ideas. I dont wont to end up with another system on my Mac
Anybody? Anything?
Regards,
Steffen
