I have a late 2011 13"MacBook Pro which I upgraded with an SSD lately. It only has 4Mb Ram and I want to increase it as I frequently have to have several intensive apps working/open lots of tabs etc. I see that Apple say that 8Mb is the max, and yet I see many reports of users upgrading to 16Mb and claiming it works well.. Amazon has a modest sale today (Crucial 8Mb x2 and 1600Mhz rather than 1333) and I'm wondering if I will actually take a performance hit by using more than the recommended RAM or if not a hit, then receive no benefit above 8Mb. Any thoughts? --- Post Merged, Jun 20, 2016 --- Apologies to posters and forum users. I see that several threads covered this very issue. Mods please delete my thread - Thanks.
