I bought my memory as an extension to the standard built-in 4GB of my Macbook Pro 13 inch early 2011. Especially for the operation of Parallels on the Mac, the 4GB of RAM were almost always at 100% utilization and the Macbook had to outsource to the hard drive, which was slowly maintains it. Even with many tabs in Safari / Firefox Wirde the memory already scarce. Unscrewed So the 8 GB Corsair ordered base of Macbooks to the 10 screws (one loses when installing the RAM is no guarantee as to the official Apple support site to read is) old RAM out, new RAM purely clicked and screwed again. No 15 minutes work. Here, you should not save the screwdriver, however, a fitting is Pficht.
After the exchange of good flits apple, as never before. Parallels needs not even half of the time to start. Even a common work on Brower and Parallels is possible without any problems.
