Il Mio Problema
The iMac needed a RAM upgrade before it could get Mac OSX 10.11 installed.
La Mia Riparazione
The repair went well. A simple screwdriver to remove the cover and then I inserted RAM into the empty slot.
Il Mio Consiglio
Removing the memory that was in the computer was difficult. This required a needle-nose pliers or something that can grab the chip. You cannot remove it with just fingers.
