seems that at one time for macbook Late 2009 A1342 used 12GB. One 8GB and One 4GB, it ran hot all the time and curdled the rubber under the bottom panel. But it was nice, also had 16GB Macbook A1342, 2010, 7 so they were each comparable, yet….the rubber almost turned into legs underside, it burned out after year.
