Chosen Solution
I got the macbook yesterday, and it was working fine. I went to get an SSD and a ram upgrade at a local hardware store. I got the SSD and the salesman tried installing numerous ram modules to see what worked. Repeatedly swapping them till one combo of a 1067 and a 1600 MHz worked. As i used it and saw it was indeed functional, it crashed immediately. It refused to boot-up since then even after swapping the original 2GB kit back in. Or so I thought. Turns out the chime arrives 57 seconds after the button is pressed. Till then the device stays on a black screen, no chime with the HDD and DVD drive spinning. After the chime arrives, the sound starts breaking? and then I’m presented with the white screen. I’ve already tried to access multiple recovery modes but all of them result in a white screen. Even SMC reset and PRAM reset did nothing to help. I’m not sure what to do as of now. Currently I’m creating a High Sierra Install Disk using transmac.(Dont have another mac) hoping it will boot off it.
Please advise
First you need the correct RAM for your system: 1066 MHz PC3-8500 DDR3 But before you can go beyond 4 GB you need to update the systems firmware (EFI) from what the system had for the older OS-X’s. So you need to get back to the original RAM config and then you need to upgrade your OS first to a newer one. I strongly you don’t go beyond Sierra (macOS 10.12.x) as Apple has issues with SATA based systems. You’ll need to create an OS installer disk to boot your system from. Either an external FireWire drive or optical drive. Depending on your exact OS (firmware) installed presently you might have bootable USB drive support. Here’s the steps to make the needed installer How to create a bootable macOS Sierra installer drive FYI the max this series can support for RAM: 2.26 GHz - 8 GB2.4 GHz - 16 GB
