OS X :: Is Normal For Network Usage To Spike Every So Often In Activity Monitor When Not Using Anything
Jan 27, 2009
it is normal for network usage to spike every so often in activity monitor when I am not using anything on my mac, and don't have any apps open? For example, if I open up activity monitor, click on the network tab at the bottom, i'll get a little spike in data received every so often, maybe every 20-30 seconds, usually 50-200 bytes, nothing big... Occasionally there will be a little red spike for data sent mixed in there too, about the same size, every once in a while.

So maybe what I am looking for is in the activity monitor, but I just can't find it. I always see people on here posting screen shots of their CPU usage. If they have a quad core machine then there are four columns with blue in it showing the usage. Where can I find this in OS X, or is this a 3rd party program?

I recently upgraded my RAM to 16 GB from the original 4. I notice thru the activity monitor that my current usage is 13.54GB. Is there a way to reduce the active usage of RAM via the activity monitor, or is this not a big deal?
Info:
MacBook Pro, OS X Mavericks (10.9.3)

I have a steady stream of spikes in my network tab of activity monitor despite being idle on the internet, not browsing any pages or downloading anything. Does this mean I am being hacked?

I have just successfully tethered my Nokia 5800 to my MBP and its working great... just one question, is there some way to monitor (maybe like a widget?) how much data i have upped and downloaded?
The reason i ask is because i have a package that allows me 1gig of traffic a month, after which there are some stupid rates *per day* of usage and the speed will be throttled as well.

I'm looking for an app that monitors my network usage. Currently, I use iStat Pro, but that "forgets" the "Total In" value upon reboot.
I want to monitor my network activity over a month or so, to see what my average usage per month / day is.
Is there any app that keeps the progress?

Someones I see that my download speed is maxing for no obvious reason. Many times I discover that it was Software Updates doing its thing.
But how can I identify the culprit when it's not SU?
Is there an application that can list all the apps or processes that access the net?
(I do have Little Snitch, but it doesn't tell me when "allowed" apps access the net.

Is this normal? I'm pretty sure it's not, at least the iTunes bit. I am using cover flo and I know that's supposed to increase the RAM usage but I don't even have the window open (it's in another space.) I've been seeing this high amount of RAM usage lately so I ran techtool deluxe and there was an error with the volume structure. I repaired permissions from the OS X install disk and since then the volume structure test passes but I'm still getting the unusually high numbers.

Just wondering if this is normal? Almost 30gb of VM in use? I'm encoding one of my DVDs and Handbrake is only using about 90mb of real memory while a bunch of background apps are using about 600-800mb of VM memory. Yesterday I encoded a DVD in like 20 minutes. I did a restart to refresh my memory but it's taken like over 2 hours of encoding and it's not done yet.
Attached is a picture of my Activity Monitor.

Whenever I open a link in a new tab, Firefox maxes out CPU usage at 100% for a few seconds. Happened just after I upgraded to 3.5.5. OS X 10.5. Intel.

I was checking the activity monitor and looking at the RAM and reading Apple's doc and the Activity Monitor RAM section.
At this moment, all I have is Firefox, Activity Monitor open and that's it, obviously there's system stuff going on as well. I took a pic and attached it.
Though is USED 1.25GB high, as it sounds real high to me. Is it too high, if so how can I lower it?
The Mac works fine.
I've been thinking to increase the RAM recently, and purchasing an extra 4 or 8 GBs
I have Intego's Virus Barrier too, any need for this?

do you think the 17 macbook pro is too big for normal computer usage (not talking about professional usage they require the extra size like photographers and video) is it too big for the rest of us? Is the extra screen space and pixels not worth the compromise in size?

Is it better, during normal usage, for example at home, where you could either charge your MacBook Pro or let the battery drain until it is used up (5%, ...).
Some people say that letting the battery cycle is the best option, yet other people, including my friend who had lost many many cycles even though he had attempted precautions (Dim screen brightness until one block remained, wireless off, bluetooth off) had said that having your laptop plugged in as muchas possible is the best option, as there would be no cycle change.

It looks like the surface of a few keys has been eaten away by acid, I can only imagine it has happened because my fingernails touch the keys through normal typing, but this is completely unavoidable unless I type like a one-fingered man. It mainly seems to happen on the A and S keys, this has happened on my white MacBook, Wireless Aluminium keyboard and Wired Aluminium keyboard, but as they are so expensive to replace I am not willing to buy a whole new keyboard for this. Also, one of my cmd keys has an odd stain on it, possibly from a crumb or droplet of orange juice which I'm sure I would have wiped off immediately, I wouldn't have expected plastic to stain so easily. Has anyone else found this with their Aluminium keyboard?
I suppose there's nothing much I can do to prevent it (I refuse to use a silicone cover), so my option appears to be just to replace those keys damaged through wear and tear however I can. Are the keys interchangeable between these three keyboards? (Wireless / Wired Aluminium, white 2008 MacBook Core2Duo) The main keys look the same apart from the bottom row on the Wired Aluminium keyboard which are a bit wider.

iMac, Mac OS X (10.6.7), iMac 27 inch i5

I'm not sure if this is cause for concern but it seems like my "free" memory has been really low as of late.
I use Safari and Mail 90% of the time. The other 10% is occasional iTunes use, MPlayer use, and Preview use. Is it time for me to upgrade to 4 GB of RAM?
Note - I do use the following extensions in Safari: AdBlock and YouTube5.

I installed Leopard from an OS disk I purchased to upgrade from Tiger. I just went to launch Activity Monitor and it is not there? I checked Applications and Utilities. From what I read it seems that Leopard should have activity monitor.

Im running SL (updated of course) on my MacBook Pro 4,1. Im fairly new to Macs and to be honest I didnt even know about Activity Monitor till very recently. So I figured I would check out whats going on with my system and fire it up. Activity Monitor does not respond. It starts to open but then sits at this screen with a beach ball...
After a while I usually just Force Quit. Ive ran Onyx recently as well as Disk Repair and everything seems ok.

A while back I installed an application that allowed me to stream media from my Mac to my PS3, called Gridcast. It didn't work well, so I got rid of it. Since then I have had two processes constantly running, "gridcastd" & "GridCastAlerts." When i select and quit the processes nothing happens, they just continues to run.

According to the screenshot, both Users (green) and System (red) uses 0,19% CPU each. Which means that idle (black) should be around 99%, which it clearly isn't. If I check each process individually, none is using more than 1% of CPU. The screenshot is taken after a reboot and I don't use and third-party background services like VMWare. It's Mac Pro 2.66 Quad (2009).

I've got the activity monitor open in front of me. There are the usual apps I can see, Logic, FF, iTunes, Finder, MS Messenger etc etc. Though there is a lot of other stuff, I don't know what it is (probably system stuff?). For instance there is configd, syslogd, mds, cron most of these have root inb the server column. In the User column for my name I can see mdworker, pboard, launchd and couple of others.

I have recently tried changing the Activity Monitor Icon by using Candybar, for some reason Candybar does not have a Activity monitor in the menu. I have than went to Activity monitor application which is on the desktop and clicked on " show package contents" + "resources" and dragged the original activity monitor icon to a random folder and dragged a new icon into the resources folder. I logged out and logged back in and now the icon did now show up, there is a application icon now.
I have dragged the new icon out and put the old one back in the folder to see if it would go back to its original icon and now it does not go back to how it was in the first place, so pretty much no icon exists but only a application icon shows but the program does open up. Another thing I dont understand is why I could not see a Activity Monitor Icon in the CandyBar program, I am not sure how to change the Icon or how people change it or why they have modified activity monitor icons is you cant change it.

Using SL. I installed iStat and it reports less "wired memory" being used than Activity Monitor. Right now iStat reports: 449MB wired, 515MB active, 364MB inactive and 2.45 GB free. Activity Monitor reports: 706MB wired, 515 MB active, 364MB inactive and 2.45 GB free. Also, our school macs are at a whopping 100MB wired, whereas I'm always above 500MB.

The computer, Mac 10.4 Tiger, sent a message that my Startup drive is almost full. I tried to do the best to make more space available and inadvertently must have done something to the files of the Activity monitor. The next morning when I turned the computer on, it went up in smoke, i.e., disappeared and cannot be found in 'applications'.
Do I have to reinstall? Can I reinstall just for the Activity Monitor or ?

I leave the Acitvity Monitor running all the time with my CPU Usage as the dock icon. I like to see the cores working away. On my Quad MacPro at work I have four blue bars, on my old iMac C2D, MacBook etc. I have two bars. On my new i7 QC iMac I am only getting one bar. Any body have any thoughts on why this is? Has Apple changed the way the icon shows cores? Here is a link to a photo of my current dock on my i7. Current Dock Icon on i7 Quad Core
