I just upgraded my iMac to 32GB of memory, yes Thirty Two GB!
Why? well first thing, why not but on a serious note, it runs much faster and gives me room to run as many apps as I want without it going into a spasm every time I want to do something.
As most of my clients know, I also do other things on my Mac other than just ‘work’ I also use it for my music productions, coding, building websites and even video editing, so the RAM (geheugen in Dutch) comes in really handy, and it’s VERY cheap these days, so there is no reason why you wouldn’t.
The more RAM and free HD space you have on your Mac the better it will run, also fixing the permission on your drive/OS will help tremendously. If you haven’t done a spring-clean on your mac since you have bought it, this might be a good time to do so, and also upgrade the memory (RAM) while you are at it, it’s well worth it and you will get much more pleasure while using the Mac.
Remember, a tool is only good if you sharpen it.
If you need help with any of this then please do contact me and lets get your Mac back up to speed again.
