Activity Monitor -- Memory.   Details Needed.

Could anyone point out what exactly the "Free" and "Inactive" memory spaces are??
I'm running on a 2GB RAM MacBook Pro. I don't run too many mem intensive programs. But quite often the "Free" mem would drop to 100-150 MB. But at that point, the "Inactive" mem would be around 500-600 MB. So what exactly a I looking at? Am I facing a mem crunch?
I'm new to OSX. from my previous experience with Windows OSes, how much ever RAM you give it, the OS will take a huge chunk and then free up as necessary. Is it something like that that I'm looking at over here? Or am I supposed to go for a mem upgrade?
And I know the next question is might be out of place, but, after quite wome time of browsing on Firefox, it seems to take 500+ MB of RAM. Is that normal??
Thanks in advance for your replies & suggestions.

A detailed look at memory usage in OS X
Understanding top output in the Terminal
The amount of available RAM for applications is the sum of Free RAM and Inactive RAM. This will change as applications are opened and closed or change from active to inactive status. The Swap figure represents an estimate of the total amount of swap space required for VM if used, but does not necessarily indicate the actual size of the existing swap file. If you are really in need of more RAM that would be indicated by how frequently the system uses VM. If you open the Terminal and run the top command at the prompt you will find information reported on Pageins () and Pageouts (). Pageouts () is the important figure. If the value in the parentheses is 0 (zero) then OS X is not making instantaneous use of VM which means you have adequate physical RAM for the system with the applications you have loaded. If the figure in parentheses is running positive and your hard drive is constantly being used (thrashing) then you need more physical RAM.
It's not abnormal for browsers to eventually use a huge amount of RAM. Use the latest version of your browser that's available. Emptying some of the browsers caches like the History cache will help somewhat, but the best way to recover the memory is to quit then relaunch the browser - or just don't worry about it and put more RAM in your computer.

  • Activity monitor memory numbers don't add up

    Activity Monitor reports that I have 7.99 GB of memory in use. However, the numbers for individual processes don't add up to nearly that large of a number. What could be causing such a huge disparity between those two? Is there something I'm missing (and yes, I have it set to show all processes)?

    For one the File Cache is not included in the process display as the use of the file cache is system wide. It is also not shown in the kernel usage.
    At the moment Activity monitor for my system shows the Kernel using 1.019 GB of real memory, the File cache at 2.95 GB.
    There may well be other memory allocations that are system wide function and services that are not readily attributable or allocatable to individual processes. If you look at the screen shot above:
    Memory Used = App memory + File Cache + Wired memory.
    I suspect that App Memory = the sum of the Proceess Real memory column

  • Activity monitor memory usage pie chart gone?

    What happened to the pie chart that sits in the dock that shows memory usage?  I found this very useful in the past, and Mavericks seems to have removed it from the dock options.

    Uhhh, I know it's a bit late for this but...
    darlingdearie wrote:
    I don't have a dock icon called "memory pressure graph".
    I have
    CPU Usage

    Disk Activity
    so it's hard to know what you're taking about when referring the the "memory pressure graph".
    Please clarify. Thanks!
    ... it sounds like you have a previous version of the Activity Monitor.  The one that comes with 10.9 has
    CPU
    Memory
    Energy
    Disk
    Network
    The memory pressure is at the bottom of the Memory tab.

  • Activity Monitor Memory Pie Chart

    I set the dock icon to monitor my memory usage as I do a lot of work in VM's that can chew through what's available.  After updating the only icons are CPU, Network, and Disk usage. What happened to Memory?
    And yes, I know there are other more informative resource monitors out there, but Activity Monitor had the best "at a glance" dashboard.

    This is no longer an option, especially since Mavericks has new memory management routines (ie, memory compression) that make the charting of memory usage less straightforward. Apple has switched to a new "Memory Pressure" approach to viewing memory usage, which is available in the Memory section of Activity Monitor, but so far has not been added as a Dock icon option. Hopefully Apple will do so, as this would perhaps be one of the more useful Dock icon options.

  • Activity Monitor, Memory and Freezes

    I've had a few Logic freezes recently so I open Activity Monitor to try and find some info. Firstly if the CPU use and threads next to Logic Pro keep changing is there a chance that Logic will unfreeze if it's been stuck for say over 5 minutes?
    Also I'm trying to see how near I am to the memory ceiling. I've got 32 GB in my MacPro so it's not a shortage of RAM more hitting the single app limit. I don't understand the relationship between "Real Memory" and "Virtual Memory" as regards the single app limit. Logic has just crashed and the associated readings are Logic Real 2.13GB Virtual 3.88GB, VSL Daemon Real 7.02MB Virtual 867MB, VSL Server 2.35GB Real 3.31 GB Virtual. ousiad (is this East West Play plug-in?) 816kb Real 2.57 GB Virtual, Vienna Ensemble 882MB Real 2.5GB Virtual. Total free memory is 20.11GB.
    If someone can help my understanding this would most be welcome!
    Thanks
    Julian

    "Virtual 3.88GB" - That's the one that kills your Logic app.
    You can read a lot on the forums that Logic has this limit of around 3.5GB of memory that it can allocate. I want to point out two things from my experience.
    1) This limit is about the "Virtual Memory" not the "Real Memory".
    2) When you get close to that limit, Logic just crashes. You would figure that it might give you just an alert box with a memory warning, no - poof - Logic is gone.
    A few more things.
    * Keep your Activity Monitor open and be very careful when you go across the 3GB "Virtual Memory" line. Every additional Plugin could push you over the edge.
    * Besides loading additional instruments, there are other factors that you should be aware of. i.e. Apple Loop Browser. If you have a big Apple Loop library and you make a search on all loops, you can see in the Activity Monitor that such a search could require a few hundred MB of additional Virtual Memory. That's enough to cross the line and crash Logic. Believe me, it took me a while (and a lot of frustration and restarts) until I figured that out.
    So why the difference between the "Real Memory" and "Virtual Memory" number. I seems that this leads into hardcore programming voodoo,aka "I have no idea". One observation I made is the impact of the graphic cards. Usually the Virtual Memory number is about 300-500MB bigger thatn the Real Memory number. When I changed my 2 graphic cards to new ones with more VRAM the difference between the Real and Virtual Memory number grew to 1GB . Don't asked me how long it took me to figure out that relation. All I saw was that I couldn't load big Logic Projects that I worked on before with no problem.
    Bottom line:
    The more stuff you load into Logic, the closer you have to monitor Activity Monitor and save more frequently.
    Think about how often you read forum posts that Logic is completely unstable and crashes all the time. I bet that a high percentage is related to user hitting that Virtual Memory limitation.

  • Running Activity Monitor To Shut Unnecessary Functions Off?

    I just ran Activity Monitor to see how the CPU on my MacBook was doing and saw all these "root" functions and this Quicklook thing that list almost 600MB of RAM/Virtual Memory usage. iVirus usage 171MB. Are there ways to disable apps and directory actions that are totally unnecessary to save RAM and CPU actions? Any links to Activity Monitor tutorials?
    Also since the SL 10.6.1 update, the fan comes on more frequently and the casing underneath is getting warmer. I assume this has to be related to something related to what is going on in Activity Monitor. Any clues there?
    I have 4GB RAM.
    Thanks for any help and ideas on what could improve the MacBook performance.

  • Activity Monitor misreports RAM?

    I have the brand new aluminum macbook with 2 gigs of ram. I looked in activity Monitor before and it was telling me that I was using 500 megabytes of ram, with no programs running. I looked at all the processes and they could not possibly have added up to 500. I know that green and blue are free and that red is for the OS. It was just the yellow that I looked at and all the processes, even including kernel_task (which is counted under wired, right?), could not have added up to 500. Please help!

    You've given us nothing to suggest a problem. Activity Monitor does not provide information on background processes. When you say, "they could not possibly have added up to 500," that means you don't really know what they added to nor that you know what to add.

  • Memory usage needs defining

    Can someone please explain the terms that are listed under the Activity Monitor. I have
    Free - 169MB - I understand this one
    Wired - 1.13GB - ??
    Active- 557MB - ??
    Inactive-157MB - ??
    Used - 1.83GB - I understand this one.
    I am running VM Fusion when I took this snapshot and I just ordered more memory to upgrade to 4GB to help my windows sessions.

  • Activity monitor Page Out question

    Is there a way to get Page Outs to report the number of page outs rather than bytes ?
    And when did this change, as it used to report in # of pages.... I think in 10.5

    Sorry, but that cannot be changed. If you want a better report of that information then open the Terminal and enter: top then press RETURN. Top's information is more complete than what is reported in Activity Monitor. Also see:

  • Can not find my Program in Lion Activity Monitor until reboot again

    Hi,
       I have tried to installed the datacard driver and user interface program in Lion and reboot; however, the resident program to detect the device of datacard does not exist in Activity Monitor.  I need to reboot again, then I can find it exits in Activity Monitor of Lion.  This issue does not happen in Mac Snow/Snow Leopard(32-bit/64-bit).  I use the Metapackage or terminal command line to install and both need to reboot one more time.  My script is
    sudo defaults write /Library/Preferences/loginwindow AutoLaunchedApplicationDictionary -array-add '{"Path" = "/opt/data/Monitor.app";"Hide" = "0";}'
        Is it a side effect of finder known issue in Lion ?  Or I need to use another way like "Launch Daemon" or "Launch Agent" to do?
    Many thanks for your comment.

    I think you should review what you wrote. There is no question, hence, my reply. I can't tell by the AM listing what applications are using memory. You need to click on the Real Mem column once or twice to display in descending order.
    Aside from what you see in AM, what exactly is your problem or perceived problem. You are very low on Free Mem at the moment the screen shot was taken. Those displays are not depicting your computer's instantaneous memory usage.

    Adding RAM only makes it possible to run more programs concurrently.  It doesn't speed up the computer nor make games run faster.  What it can do is prevent the system from having to use disk-based VM when it runs out of RAM because you are trying to run too many applications concurrently or using applications that are extremely RAM dependent.  It will improve the performance of applications that run mostly in RAM or when loading programs.

  • Updated to Mavericks. Now theres tons of activity in my terminal and my activity monitor doesn't seem normal. I want to think someone's hacking me, but i need experienced help please!

    I spent all night trying to fix this. It seems to me that someone has been trying to hack into my system with all of the random codes/lines in my terminal and i have all of his foreign IP addresses. And now i get this strange message that popped up in my terminal. Idk what it entirely means? I would very appreciate if someone could just walk me through this. Thank you very much.
    First time poster. I have Macbook Pro. OSX. Just downloaded the new mavericks. I'm i have my firewall on. I stay secure. I run Netbarrier, Virusbarrier, IdentityScrubber.
    I know something is a little odd or just doesn't make since about my activity monitor. Then my WiFi was hacked last night and this person was writing tons lines of commands/codes that i found in my terminal and my activity monitor doesn't look normal,  and I've only been a mac owner for about a year now and i'm learning more and more but while trying to figure out what was going on this message popped up which concerned me the most. Any help would be most appreciated, thanks guys. I have my terminal full of his foreign ip addresses i noticed, and a lot of other commands and lines he wrote out that i definitely did not type myself. Can anyone give me a hand on this? Thanks

    haha, so now i'm thinking. I'm learning the terminal as fast as i can but there are several lines of codes and commands in there that throws up red flags to me that i don't fully understand. It just looks fishy too me. It would be highly appreciated if someone could just check this out just to tell me that i don't need to worry about it. Or point me in the right direction. I just feel un easy about this. ha.

  • In OSX Activity Monitor, what's the difference between 'free' memory and 'inactive' memory

    In OS X Activity Monitor, what's the difference between 'free' memory and 'inactive' memory. My daughters 2Gb MacBook Pro is very slow, it probably needs more memory but there is almost 1Gb of 'inactive' memory but no 'free' memory when an application is opened.
    Thanks

    Free RAM is the one that has not been used by any application since you started up your Mac, and inactive RAM is the one that was used by an application and it is not in use anymore.
    1 GB of inactive RAM is a lot, and it may be the cause of the slowness. There are a lot of apps that allows you to turn inactive into free RAM. I use FreeMemory, but have a look at the Mac App Store.
    If you are a developer, you can do that with a command you can type into Terminal:
    sudo purge

  • Compressed memory showing 0% in activity monitor

    On one of my Mac Mini's (late 2012), upgraded to 16GB RAM, I keep getting out of memory messages when running apps and on checking the activity monitor it is showing 0% for all running apps under the compressed memory column. I'm running OS-X 10.10.3.
    Any ideas on what's going on here? I've tried resetting the NVRAM....

    The system isn't compressing memory because is doesn't yet need to; 16GB is pretty generous. The 'Memory' column includes shared memory (system libraries) so there can be a lot of 'double counting' in the figures. You can control+click on the 'Memory' column headers to get other measures.
    Try opening Safari and open a dozen tabs with different complicated pages in each one of them, e.g. some pages news.bbc.co.uk. I'm sure you'll be able to start compression eventually.
    Meanwhile, your original issue is a bug, or corrupted file, associated with Solibri Model Viewer. You'll probably need to contact its developer for assistance as I doubt that enough users will be reading this forum for you to get an answer here.
