My Macbook 13″ (white, mid 2009) doesn’t start.
Checked HD, RAM, Battery, Charger etc. Did a Apple Service Diagnostic EFI and it passed the test. Can’t run the OS test. A few times I could enter the OS and it worked for a while. Most of the time it shuts down on the apple logo. Tried resetting PRAM but the mac does n’t restart automatically during the process. Tried reinstalling the OS but it shuts down. any idea or help? much appreciated your comments, ideas and help.
