I just installed OS X on my Dell Mini 9 this weekend. Beautiful machine!
I thought that I should update the memory to 2GB from 1GB, and that is when the trouble started.
The machine started allright, I ran the dellefi, did the usual updates using DELLEfi1.2a5 and everything worked nicely, until I put the machine to sleep. Now the machine hung, and I had to reboot. From that point on the machine was unstable, frequently hanging after around 5 minutes, reboots were really slow, if they work at all, and when I try to update dsdt.aml again, it sometimes says that it could not be deleted.
Now I see that some of the issues that I am having are the same that others has had before, and the advice is generally to delete the dsdt.aml, rerun DELLEfi, reboot and then reboot again. And I have tried just that, many, many times, but the problem does not seem to go away anyhow.
The only time the machine works similary to how it worked before the problems is when I have just deleted the dsdt.aml file and rebooted, but not created a new one using DELLEfi.
After running the DellEFI successfully, and rebooting, the machine only gets to the spinning wheel before turning itself of. The second time the reboot works, but slowly and not at all in the speed it had before the memory upgrade.
Yes, the SO-DIMM might be broken, but that seems slighty unlikely in my experience.
Do anyone have any advice on what I should try next?
I do love the machine, so any help would be appreciated!
