CommunityĪ more in-depth version of the rules can be found here And you should pair RAM modules of the same capacity, if possible.Welcome to r/Apple, the unofficial community for Apple news, rumors, and discussions. If you decide just to fill empty slots, the same applies. It’s a good idea, though not essential, to buy all the RAM you fit at the same time from the same manufacturer. That will often mean removing the existing modules and replacing them. But as a rule of thumb, the effort of performing the installation compared with the marginal cost of bigger RAM modules means that it’s worth maxing out your Mac’s RAM in one go. How much RAM you add and how you add it is dependent on your Mac. If it turns red regularly, it’s worth the expenditure.

If it’s permanently green, you’re probably not going to see a huge difference by upgrading. The easiest way to do this is to fire up Activity Monitor (it’s in Applications/Utilities), click on the Memory tab and keep an eye on the memory pressure gauge at the bottom of the window. Before you go ahead and spend money, however, it’s worth trying to figure out how much of a difference it will really make, if any. In the past adding more RAM was the go-to solution for improving a Mac’s performance.
