My Activity Monitor is showing that something is downloading, I can the download activity on the graph and the overall speed is shown as 'Data received/sec. But I'm stuck trying to figure out which process it is that's using the network? I can sort by 'Rcvd Bytes' or 'Rcvd Packets', but those would seem to be cumulative totals. Isn't there some kind of '% Network' column??

I had my Mac M4 on sleep, as usual (macOS 15.5). Today when I opened it, it was warm. I took a look on the cpu usage I saw that it was walking up in around 1h intervals with a 15% user usage. When I opened it the cpu usage dropped and the machine cooled down. I would like to find what's the processes causing this usage as it don't seem right. Is it possible to find the logs of CPU usage % on a given time in the past? Or how to record CPU % usage per process (like as Activity monitor reports) in the future ? --- **Update**: I made a launchd script to dump 3 activity logs every 10minutes in a textfile. The process using resources is usually mediaanalysisd

Recently, i noticed TextEdit on macos bigsur(M1 chip) taking more than 3GB ram and is not responding after I try zooming in. Even though my .txt wasn't very big(just 4KB, barely 50 lines of text). Anyone experiencing the same, please respond? Is that a bug ? The ram consumption is increasing exponentially unless I force quit the app. Its working absolutely fine if I don't zoom into it. Edit : It happens with any text file with TextEdit which is a bit large, e.g more than 50-60 lines. For .txt files with lesser content, its not happening.

Once in a while, I eschew my Apple Watch in favor of something else. On those days, I have no tracking of activities. However, iPhone supports at least some activity tracking on its own (specifically steps). Is it possible to have my iPhone track activities when I'm not wearing my Apple Watch?

I am unable to find any meaningful answer anywhere else on the internet. You can maximize Safari to full screen. You can maximize Pages to full screen. You can maximize most of the general use native macOS apps to full screen. But you cannot maximize Activity Monitor to full screen. Why? I have a dual monitor setup and many times I'm running a program on one screen and want to monitor its use through Activity Monitor on the other screen. On clicking the green button, Activity Monitor does not go 'Enter Full Screen', but just 'Zoom's to use the whole screen.

Since the last major upgrade to macOS Mojave, I have the **Wi-Fi** process taking up a lot of memory and in an exponentially way. Time to time I need to force quit it in Activity Monitor because it takes too much memory (around 5 GB). Did anyone else faced the same issue and was able to resolve? I am using a MacBook Pro 15-inch 2017 with macOS Mojave 10.14. Edit: I've recently noticed that the Wi-Fi process uses a lot of memory when connecting to the internet through personal hotspot on iPhone.

Through the desktop widget for Screen Time on my M3 Max MacBook Pro with macOS 15.1.1, I noticed how usage for today was around 35 hours (!), 12.5 of which were occupied by the com.apple.controlcenter process. Browsing Activity Monitor didn't return any relevant result for that specific process, even though looking directly for "Control Center" returned the expected result. Here is a screenshot of System Settings > Screen Time > App & Website Activity, filtered down for only my Mac in devices. As you can see, it shows Control Centre as being an in-use app for close to 14h, something that I have honestly never seen before. Safari is running, but I have certainly not kept it in focus for 12h! YouTube was running on the iPad as a background music for my workday for 6h (checking the iPad page of Screen Time), but it was never once opened on Mac. The Tips app was running, but in focus for perhaps 10 minutes while I was writing a blog post? Then what is 5h of Dailymotion? I have no app that is called like that, no process running that answers to it, nor any Safari tab that has it. Any idea what may be going on and what I could do to solve it? Just a bug in Screen Time, perhaps?

MacOS: Sonoma 14.6.1 I have a C++ program I have developed on my Mac and that I typically run from the command line. Depending on certain runtime parameters that I set, the program can run from ~10 minutes to ~24 hours (or more, I suppose, though I've never tried). I have been having a recent issue where the process running the algorithm for a medium-sized job mysteriously gets killed ("Killed: 9 \") after about 3 hours. I suspect that there is a memory leak and that some component of the OS is killing memory-hog processes like this one. To test this, what I would like to do is execute the program and launch a device to record the memory use of the relevant process. I do not want to manually monitor the memory usage through a device like Activity Monitor, top, htop, ctop, etc., until the process dies. I want to launch everything, forget about it, and then check the results in some log after, say, 6 hours when the process will have certainly been terminated. Is it possible to do this logging? __________________________ EDIT (2024.10.28): To be clearer, I would like to record the time series of the memory usage at fixed intervals over the life of the job. It is this entire time series, and not just a summary, that I would like to view once the process has finished.

In Activity Monitor.app I've wanted to find out what are the x86, Intel processes that I still have on my *Apple Silicon* MacBook. The only two x86 processes are CarbonComponentScanner and VisualizerService-x86 (Music). Does anyone know what they are and what they are doing?

Unable to stop the process "idleassetsd" to consume internet bandwidth, While force quitting the process it starts consuming the bandwidth again, Nothing is working to stop it Observed under macOS (Ventura & Sonoma) Sync to iCloud is turned off, No developer software is installed. Also the auto software update for Mac is Disabled. Attached is the Snapshot for reference. Appreciate your help in advance PS: Same problem happens in Sonoma:

I've been using Macs for 15 years, starting from a 2009 MacBook Pro with 4 GB of RAM, then upgrading to a 2016 MBP with 16 GB of RAM, and now, since last December (2023), upgraded to my first Apple Silicon Mac, an M3 Max 16" MBP. For context, the first MBP has 320 GB of spinning storage, the second has 500 GB of SSD, and this one has a 2 TB SSD. Never until yesterday I had received the message shown here: "Your system has run out of application memory". I've been using the same kind of apps since 2009, and always had plenty of apps open at the same time, and I'm doing nothing really different now that I wasn't doing before. I regularly (at least once per week) restart or shut down the Mac. This is from Activity Monitor just after the message came up: I initially thought this was Acrobat since after quitting it (which was using about 3.5 GB of memory with no open document at all...) the situation stabilised for a while, then it happened again yesterday, and today when I opened Illustrator. Just launching the app caused this message to pop up. I have read previous posts on this same issue but no one seemed to relate to Apple Silicon. Again, on Intel, I have never had this, and with much less memory than I do. Also, look at the graph, no swap used at all. Shouldn't Mac just use Swap if there is an issue instead of asking the user to force quit apps? I honestly do not understand what is going on here. The SSD is about 80% free! Finally, I have been doing the same things since getting this Mac, and it had never happened before. Even if I launched all apps together at the same time, this should just not happen, and the system should manage memory far better than this. For the records, I am not noticing any slowdown in the way the Mac behaves, the CPU usage is not stressed at all. What can / should I do?

I noticed that my MacBook gets hot and noisy (fans) when using VS Code (v1.31). The Activity Monitor shows the process **Code Helper** using more than 100% of CPU. It started happening with one repository which is huge. Only one window opened, no files opened, and it always uses more than 100% CPU. Checking in Microsoft/GitHub, there was an issue reported but they closed it saying *"This issue has been closed automatically because it needs more information and has not had recent activity."* , but it is still an ongoing issue. I tried some of the recommendations in the comments but didn't work. Does anybody has more info and/or know how to avoid this? Is it possible to make some configurations for VS Code to not burn the MacBook?

The Family process (/System/Library/CoreServices/Family.app/Contents/MacOS/Family) is hanging randomly on macOS. When this happens Screen Time settings fail to sync from iPhone to iMac, Find My struggles to locate devices, and cpu begins to overheat. I have been on the phone and screen shared with Apple Tier 1 with no resolution. There are multiple questions on Apple community, reddit, and other forums trying to resolve this issue. AFAIK none have been successful. One suggestion was adding /System/Library/PrivateFrameworks/IMCore.framework/imagent.app as an Allow rule in Network Firewall ( OR even just turning off the Firewall in Network settings ) to test if that solved this issue. So far (after 12 hours of monitoring Activity Monitor) it seems to have prevented the Family binary getting stuck in a (Non Responsive) state but hundreds of errors in Console.app suggests the issue is still present. With Firewall off I see hundreds of console faults for the Family process:

Why is this process hanging?

For the past few days, Screen Time has been showing me continuous activity from a specific website (I assume the grey circle is a website activity). The screenshot was taken this morning upon opening the lid of this M3 Max MacBook Pro which, at least in theory, should have been fully asleep all night. While this website _per se_ should be innocuous, I cannot find it anywhere among my open Safari windows and tabs. I've cleared history from Safari, quit Safari & waited to see what was happening and the activity kept rising. Activity Monitor doesn't show any entry connected to "Halstan.de" or to any part of it, in any tab (CPU, Energy, Memory, ...). What options do I have? Is it a bug in Screen Time that kept it stuck? The good thing is that I know I used that website, the bad thing is that the last tab from it was closed on Monday (24.06.2024). I've also added a time limit of one hour to just that site, but then opening a new tab and browsing to that same website works with no problem on all devices. Any help in understanding and possibly solving the issue is much appreciated.

I’m a bit intrigued by the new detailed activity monitors and progress indicators in Windows 8 (copying files, the task monitor, network activity, etc.) It got me thinking: surely there must be some **better alternatives to the built-in *Activity Monitor.app?*** “Better” as in more detailed and nicer graphs. Specifically, it would be interested and see percentage **disk I/O** (out of disk capacity), memory usage, and CPU usage in the same nice way The Building windows blog has an article detailing the new Task Manager in Windows 8. I just think that OS X’s task manager — which I have always found superior — just doesn’t cut it anymore compared to what is coming in Windows 8.

I'm unable to kill a process using any of the techniques I'm aware of ("Force Quit" in Activity Monitor, top, killall from the Terminal) and wonder if there are some additional steps I can take. ~ $ sudo killall -KILL 77439 Password: No matching processes were found ~ $ killall -KILL 77439 No matching processes belonging to you were found ~ $ killall 77439 No matching processes belonging to you were found ~ $ killall Mathematica No matching processes belonging to you were found FWIW the process is "Mathematica" which I cannot relaunch, Quit, or Force Quit, or sample, either by name or PID, and it appears to have some odd side effects (screenshots don't appear, can't empty trash, and can't even shut down the system). Are there additional steps that can be taken to really *really* kill a badly behaved process?

I would like to track computer A's CPU (and maybe memory etc) usage on computer B in a GUI similar to that of Activity Monitor. Is that possible? Preferably a free solution. I have looked at SNMP but can't find any clients similar to Activity Monitor (or free).

I'd like to be able to view my cpu and memory usage in real time. Not as a desktop widget or window application, but as a widget in the menu bar. Is this possible?

I am on my M1 Mac mini (Big Sur 11.3.1). I got a message that I am running out of RAM and should close some apps. I saw this process called qemu-system-aarch64 that takes up to 3GB of RAM. I don't know what it does and cannot stop it either. What is it and why does it eat up so much RAM?

I have a MacBook Pro from 2013, and I'm having issues in both Chrome and Firefox - both are slowing down to a crawl, and when I check Activity Monitor I have multiple processes (in all the 'tabs' at the top) slowing everything down and triggering the fan. Now I'm guessing each add-on in Firefox and Chrome creates another process called FirefoxCP Web Content, but I also have multiple Adobe CEF Helper and Google Crome Helper. Is there a way to prevent these multiple processes from starting up, without having to go to Activity Monitor and shut things down? Something like a 'basic' setting (like SafeMode) without a massive drain on performance?
