Tip # 1. Remove Login Items to lower Mac memory usage
I guess this will help with all versions of OS X from about Disabling VM is a bad idea. A better way of doing things is to force the dynamic pager to do garbage collection with the command. Very bad things can happen, from your system just being slow and unresponsive to DATA LOSS from the system memory management routines forcibly killing off processes when memory has run out for allocation requests.
Hey I wouldnt mess with the swap files because I wanted to save some space on my mac and it ended up freezing some days after. I had to take it to apple and had it reset.

Maybe it was for something else, but just in case, dont delete them. On restart the free space jumps back up to GB free but can drop to in a matter of hours with almost nothing running.
Is there a fix for this? If you are running an older version of Mac OS X, and the Mac is new enough to support it, updating to a newer release may resolve the issue Snow Leopard Name required.

macos - Why OS X use swap when there is lots of "inactive memory"? - Super User
What is swap space? So i recently started a programming course and i've been doing some basic programming usings emacs and terminal of my macbook pro. I always get the following message. Scrollback buffers may be automatically trimmed to conserve Scrollback buffers may be automatically trimmed to conserve memory.
It usually happens when i'm using emacs and i'm really not doing anything taxing. Just basic programming, i mean i have been doing the course for 2 weeks and it takes you from the very beginning. Surely my laptop can handle something as basic as a simple arithmetic prgramme?
Any computer techies out there that can help explain things to me.

Mac Virtual Memory – What it is, the Swap Location, and How to Disable Swap in Mac OS X
Rating Newest Oldest. Best Answer: Swap space is the same as "virtual memory" in Windows. It's an area on your hard drive that the OS uses to let it pretend it has more RAM than it really does. The computer swaps data between RAM and the swap space as needed. Often, swap space uses a separate partition on the hard drive, so it can't just add more from the drive's free space.
I don't know if you can resize partitions on a mac, but that might be a solution. You can also check to see if anything is using more RAM than it should. Source s: Add a comment.
An operating system is designed with the expectation that, even if a number of applications are all running at the same time, they all might not actively need resources at the same time. For processing memory as opposed to storage memory , a swap space is a dedicated section of the hard drive where CPU memory gets copied to as different applications take their turn in using the active memory If swap space gets low, the amount of 'stuff' that gets kept track of starts being reduced.
One such thing would be the scrollback buffers of an application, which helps speed up scrolling forward and back thru data. The error message is basically telling you "I'm running out of space to keep notes, so you may see a slowdown in scrolling" You wouldn't exactly 'clear' the swap space, but you could free up some of it by closing apps that may be running in the background.
You can also increase the size of swap file if you have hard drive space to spare the exact method would depend on your OS Do you have a lot of applications all running at once? Although, it may start writing to it somewhere around the halfway point at least in my low hardware performance machines.
