Memory use
« on: February 13, 2008, 09:13:21 PM »
Didn't want this to be buried in the other thread mentioning Safari's memory leak. That prompted me to check to see how much it was using on my Mini. Couldn't find it. While it's true that I forget where it was in OS9, I never knew where to find it on any later OS. I could find it on the old computer, I just don't remember where it is. (the drop down menu; I know where the old computer is) Where do you get the list of running applications and how much RAM they are hogging???

Ok, I did forget. That was mentioned in one of the other "Leopard 101" threads I started. But, in OS9 that information was available from a "direct" menu choice, not buried three levels down the folder tree. Oh, must be one of the "improvements".

Hey Gregg, drag Activity Monitor to your dock, then it's not "tree levels down". One of the improvements in OS X!

AM has dozens of uses and combinations of views. Seeing the memory used by an app is simply one of them. I usually use it more to see how much cpu cycles an app is using, some are real hogs! To see memory leaks, I would suggest opening AM and selecting "My Processes" which you may not have even know you had! smile.gif There should be a "Real Memory" labeled column, mine is squeezed down so it only reads "RM." Anyway, clicking that column label will sort the processes by memory used. The processes list may change, therefore, as their memory use changes. You may want to sort by "Process Name" to keep the list from changing. dntknw.gif

While you're there, check the "View" menu and set things up like you want. There is not an actual "Preferences..." menu item in AM, changes/settings are mostly done in that "View" menu. Enjoy! smile.gif It really is an improvement in information over OS 9, IMHO.

Or, as I just discovered, I can, well, go to the Go Menu and select Utilities which opens the Utilities Folder in Applications, and pluck that Activity Monitor right off the top of the heap. Of course, while AM is running, its icon is in the Dock.

AM shows a bunch of mystery applications running:

57    launchd   0.0   3   512.00 KB   585.73 MB   Intel   
80    pboard   0.0   1   580.00 KB   586.63 MB   Intel   
77    UserEventAgent      0.0   2   2.07 MB   588.44 MB   Intel   
183    mdworker      0.0   4   2.36 MB   598.92 MB   Intel   
112    AppleSpell.service   0.0   1   3.70 MB   601.71 MB   Intel   
82    ATSServer   0.0   2   3.26 MB   618.99 MB   Intel   
90    iTunes Helper   0.0   2   2.26 MB   848.90 MB   Intel   
76    Spotlight   0.0   2   3.93 MB   859.87 MB   Intel   
22    loginwindow   0.0   3   4.76 MB   864.86 MB   Intel   
81    SystemUIServer   0.1   7   8.84 MB   906.80 MB   Intel   

And the ones that are fundamental:
78    Dock   0.0   3   15.61 MB   915.48 MB   Intel   
83    Finder   0.0   6   16.18 MB   931.87 MB   Intel   

As well as the ones I opened:
195    Activity Monitor   1.6   5   12.46 MB   950.21 MB   Intel   
91    Remember?   0.0   2   17.57 MB   990.02 MB   PowerPC   
108    Safari   8.3   12   96.17 MB   1.00 GB   Intel

Depending on how you select the processes, you can be over-whelmed by the number and the general lack of descriptive names. I'd not worry much about any of them until you find one that is draining more than 10% of your cpu cycles. Might be worth finding out more about that one. Most are required for whatever the OS is doing, some are needed by all programs, some are just there to confuse residents of Milwaukee! tease.gif

Or even better than using the go menu, use Spotlight! Just hit command+space to bring up the spot light window. Type in part or all of "Activity monitor" and hit return to open the application. I have really started using that a lot since Leopard, since it's a handy way to launch apps without remember where they are.

You do know that you can click/hold on the icon in the Dock and set the app to remain in the Dock.

I do now. I hadn't noticed the pop-up "contextual" menu ability there, as I tend to "click quick"(ly) and not hold. Although, I probably read that in Dr. Bob's book. I try to do things I read in there to help me learn (ie: remember) them (later), but that's one I forgot to try.

Or, do what krissel mentioned, but click on "Open at Login" instead. Then you have to do exactly nothing after that to activate it. wink.gif

Ok, I double-dog dare ya to come up with an easier method than 0 steps.... toothgrin.gif

Speaking of "plist," you can now, in Leopard, view them write in the Finder using "Quick Look." Just find one you're interested in (you can maybe even use Spotlight!), select it by clicking on it and then press the space bar. There you go! Interpreting what's there is left as an exercize for the reader. tease.gif Found this trick in the latest Macworld, BTW.

Odd coincidence...I happened to find an application on my machine last night that lets you look at and edit any plist.

Here is the updated version:
