The Activity Monitor Dock Icon can display any of the following options, but only 1 at a time.ĬPU Usage, CPU History, Network Usage, Disk Activity, or Memory Usage. By keeping this application in your dock, you can simply Control + click on it's dock icon and display a number of different charts to visualize the data, without keeping the application window itself open! Mac OS X ships standard with an application called “Activity Monitor,” Located in your Applications > Utilities folder. (mostly because of heavy Adobe Apps) If you are like me, you want to know how much of your precious memory you have left, so as not to launch that one extra application that crashes your machine and causes you to lose unsaved work. This comes standard with every new Mac running OS X.īeing involved with web design, and design in general, I find myself needing to monitor my memory usage on a daily basis. In this day of soldered-in system RAM and SSDs, it is difficult to decide what to buy.This is a quick way to have easy visual access to your memory usage without having to rely on a Dashboard Widget, or even have Dashboard running for that matter. But I would have happily bought it with 8 GB if that was not an option, and it will perform great either way. Personally, I was willing to spend the extra money for 16 GB in my retina MacBook Pro, even though it uses one of the fastest SSDs on the market. But it is not as much of a necessity, so don’t fret if you can only buy 4 GB. It is wise to buy enough system RAM to handle your needs, even if your computer uses an SSD. After all, a computer only needs to be “fast enough” for the user to be satisfied, and the lifespan of the SSD is probably not as much concern as lifespan of the battery! These are true statements, but should be taken with a grain of salt. And SSDs don’t last forever, so excessive page-outs actually reduce the lifespan of your computer. This begs the question if SSD-equipped computers need as much system RAM.Įven though SSDs are much faster than hard drives, they are slower than main system memory. This is one reason that the meager 2 GB or 4 GB of RAM found in a MacBook Air doesn’t impact performance as much as one would think. Reboot, run your system normally for a few days, then check Activity Monitor. There is no hard and fast rule, but if the number is higher than a gigabyte or two over a few days use you ought to consider getting more memory! What About SSDs?įast solid-state storage (SSD) drives reduce the impact of page outs. It’s fine to dip into it occasionally, but excessive use will cause trouble! Since it is much slower than RAM, disk space should be thought of as “overdraft protection” for your system memory. “Page outs” in Activity Monitor shows how much memory has been needed but not available since your system last started up. If you have many GB of “Page outs”, you should consider getting more RAM! This is the clue you need to know if your system has insufficient memory. At the bottom, next to the pie chart of memory in use, you will see a “Page outs” value. In Activity Monitor, click on the System Memory tab. You will find this under Applications in the Utilities folder, and it shows you all Certs of useful information about CPU, memory, disk, and network activity. On Mac OS X, the easiest way to see if you have enough memory is simply to open the Activity Monitor application. ![]() Is your system constrained with two little memory, or is it just slow? It can be difficult for the uninitiated to answer this question, but it’s not too difficult to see if your system is swapping excessively: most operating systems will tell you how many “page outs” the system has needed to do, and this is a very strong clue as to whether you have enough memory or not. Main system RAM is used by running programsīut the lines blur in reality, with modern operating systems able to use disk storage for running applications. Although using disk as memory (a process called paging or virtual memory swapping) allows your system to have effectively infinite RAM, it often slows down performance to an unacceptable level.Most people are aware that computers contain at least two different kinds of memory: In this article, I will present an easy method for even a computer novice to know whether he has enough memory on his Mac! Virtual Memory and Page Outs It’s not always easy to tell if your system needs more memory, or if it’s just slow.
