If you want it to be free, take it out of the machine and leave it on a shelf.

The whole point of RAM is to use it to make the system fast.

This means making the system use as little RAM as possible. So there is no reason to do this.įor some reason, people have this obsession with making as much RAM as possible free. Like most modern operating systems, OSX can transition RAM directly from one use to another in a single operation, which is much more efficient than two operations to do the same thing. Making RAM free takes effort, effort that the system just has to undo in order to use that RAM. You can use it now and also use it later. The spinning wheel is a sign you’re maxing out your memorythat’s why apps keep acting up. So why not use it now? It's not like using it now means you can't use it later. Now is always later than some time in the past. If you're thinking 'I want it free now so I can use it later', well, 'later' never comes. It's no better than memory you don't have. Free memory is memory that isn't doing anything.
