I have macbook pro mid 2009. My OS is snow leopard, and also have windows XP installed on different partition. I've upgrade the memory to 8GB (2x4 GB) RAM from the original 2 GB.
The problem started when it suddenly run very-very slow on mac os. I restart it several time, free some harddisk space, no success.
And then it just stop, and wont boot up at all to mac os. But it worked just fine when I reboot to windows XP.
So then what I did:
- Boot to Mac OS DVD, Try to repair the mac os system. It just stopped in the middle of the process.
- Run disk utility from Mac OS DVD, verify and repair disk, found nothing wrong.
- Wipe the entire partition where my Mac OS was installed (write with zeros) and then install a fresh copy of Mac OS Snow leopard from dvd, it just freeze in the middle of installation. (randomly while extracting the apple os package). Retry several times, with diifferent DVD, no success.
- Run extended test through Apple Hardware Test, found nothing wrong.
- Boot to windows, and then do harddisk scan for bad sector to my Mac OS partition, found nothing wrong.
- Wipe the windows partition and format it to Mac OS extended, and try to install Mac OS on that partition (in expectation that it was the mac os x partition that have the problem). No success (stop in the middle of installation)
- Try to take out the RAM, use only one RAM on the slot (1x4GB, try combining both RAM into both slot available) and the redo all the steps above. No success.
- Try to format the Macintosh HD partition to NTFS and try to install Windows XP there. No Success (some system file error during the installation).
So after that I just format the original windows partition back to NTFS, and reinstall windows XP. It just work perfectly fine. So I'm running windows XP now on my macbook instead of Mac OS
I cant find the original RAM so I cannot try to run those steps above with the original hardware.
Can anybody give me some suggestion here? I live in Indonesia so its not easy to get help from apple store/support. Thanks
