hi guys
I have been given a brand new iMac mid 2010 21'5 inch model it had 4 GB ram installed default of 2x2GB sticks,
I have tried to put in 4x4GB sticks to bring it up to 16GB but for some reason its constantly rebooting with the ram in
but if I run it wit just 1 stick of 4GB it don't reboot or anything,
ive tested all the ram sticks and they are all working perfectly
now one more issue I've replaced the spinning hard drive with an SSD now its there I can install the original OS which was 10.6 with no problems
but when I try to install high Sierra which is the latest it supports I just get setup started it does it thing then goes to reboot and flashes the ? on the screen after it reboots the first time.
can I ask if this is a firmware problem ?
as I have tried to manually update the firmware but it says it can't ???
thanks for any help.
