Apple will double its current built-to-order RAM configurations for the upcoming Mac minis, and perhaps the new iMacs according to sources familiar with the upcoming product releases. The current version of the iMac includes four RAM slots, and Apple’s top RAM configuration is four 4GB chips for a total of 16GB of RAM. The new iMac, however, will be sold with an options for 16GB of RAM across two chips (2 X 8GB) of RAM. Assuming that the new iMac retains 4 slots, users will be able to buy up to 32GB of iMac RAM from Apple. However, if not, it is still notable that Apple will be selling iMac RAM in pieces of 8GB chips for the first time. Up until this point, you could buy and use 8GB RAM chips from third parties for both the Mac mini and iMac.
