RAM is easy to install, just follow the steps to upgrade your MacBook RAM. Works great, RAM increased from 4GB to 16GB. Overall there is an overall speed improvement No major complaints looks like a legitimate product I would recommend giving it a try if you need more Mac RAM These MacBooks were never intended for hardcore gaming On my husband's system it could I play Planet Base at about 30 fps so some stuff is at least playable I put the MacBook back in, upgraded the storage to an SSD and added these RAM cards.
