Remember that RAM is your computer's ability to multitask media and having more RAM will expedite your ability to scroll through media in catalogues or in finder. I won't go into detail here on why this is possible, but if you are a photographer looking to expedite your workflow and work more efficiently within your Lightroom catalogues and PSD files, then having more RAM in your machine gives your computer a better ability to do so.

Also in many cases, especially with older models, you are able to max out your RAM and put in more RAM that what Apple says you can. Upgrading RAM on Apple's website on a new iMac to 32GB costs $600 extra, which is about $300 more than getting ram from OWC. After this grace period you are essentially out of luck if the RAM needs to be replaced. At the very most, the RAM from Apple comes with a 3 year warranty. Getting third party RAM is a much better option and should be done by more people looking to work more efficiently. The third party RAM you can get from OWC or similar providers also comes with a lifetime warranty and is almost identical to the RAM that Apple is selling you. Unless of course you simply don't care about money then this article doesn't apply to you. Having said that and having worked many a moons for Apple at the genius bar I can tell you that 1.) I am far from a genius and 2.) it's just not a best practice to upgrade your RAM through Apple. I get it and I don't care if you can custom build your own PC for a bajillion dollars cheaper and in theory you say it's faster. In every sense of the word, PC's are cheaper. Before I even begin this article I want to say for the record that PC's are cheaper than almost any Apple computer and I fully understood this before I spent thousands on my Mac.
