Is there a way to see memory usage per app in macOS? That is, I want to see the **total** memory consumed by each app, including its child processes. The Activity Monitor shows memory usage by process which makes it hard to determine, for example, how much memory the Chrome app is using, since it spawns multiple processes.

I'm on macOS 15.2 and today I've just discovered a very bad habit for idleassetsd: a massive memory leak when working offline. My situation is: screen savers disabled, static background, and working mostly offline. I restarted my MacBook Air M1 and opened Activity Monitor in the memory pane; idleassetsd started popping out with a very limited usage, but then it grew up and after a few minutes is now using 21 GB of memory (mostly swapped)! While writing this few sentences, the number has already changed to 23.00 GB. This happens when idleassetsd is offline, so when my machine is not connected (really offline) or when I block it to reach the network (I'm using TripMode, but any other technique shows the same behavior). What's happening is that in the next 30 to 60 minutes my hard drive will be fully used, and my Mac will crash and reboot. If I go online the memory usage stabilize (but doesn't decrease if I don't reboot), but then the software downloades a lot of gigabytes (like described in other posts like idleassetsd going crazy ). Just for completion: the software is also writing gigabytes and gigabytes on my SSD, both when online and offline, consuming my SSD. I've tried all the solution found to disable it since the disk and network usage is a well known bug from macOS 14, while it's the first time I read about the memory leak, but none was working. Thank you all for any idea or suggestion. ps: now 25.7 GB and counting....... Update 1: I've reported it to Apple. Update 2: What I've tried to solve the issue so far: - countless reboots (forced and "natural") - removed files in the /Library/Application Support/com.apple.idleassetsd folder (and rebooted) - selected the Sequoia screensaver for all accounts - standard, not animated (and rebooted) - disabled the screensavers activation from all accounts (and rebooted) - enabled the Sequoia background on all accounts (and - guess what? - rebooted!) - killed the process - deeply searched on Google, Reddit, StackOverflow and other resources ## Logs The errors log when working completely offline is a repetition of the following block: errore 07:39:57.483776+0100 idleassetsd Connection 2058035: received failure notification errore 07:39:57.483992+0100 idleassetsd Connection 2058035: failed to connect 1:50, reason -1 errore 07:39:57.484042+0100 idleassetsd Connection 2058035: encountered error(1:50) errore 07:39:57.487919+0100 idleassetsd Task .

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 was running something on docker and this appears on the Activity Monitor. Do Memory Pressure and Memory Used have a direct relation with each other? ![Memory Pressure appears green and stable but Memory Used is 7.11/8.00GB ][1]

When I try to do a calculation that needs to allocate and use 128 GB of memory (it is a command line program written in C), the kernel kills my process with extreme prejudice. This console log entry is an example of one instance: > 9/25/15 7:08:40.000 PM kernel: low swap: killing pid 6202 (huffgrp) The calculation works fine and in a reasonable amount of time when it allocates and uses 64 GB of memory. My machine has 32 GB of RAM and beaucoup space on the hard drive. I also tried this on another machine with 8 GB of RAM, on which the 64 GB calculation runs fine as well, taking longer of course, but the 128 GB calculation gets killed by the kernel in the same way. On both I am running Yosemite 10.10.5. By the way, malloc() never returns an error, no matter how much space I ask for. The kernel will only kill the process once too much of that memory is actually being used by the process, resulting in lots of swapping to the hard drive. So there appears to be a secret swap space limit somewhere between 64 GB and 128 GB. My question is: how do I reconfigure the kernel to permit more swap space? I found a promising looking file, /System/Library/LaunchDaemons/com.apple.dynamic_pager.plist, but I don't see the secret number in there. The man page for dynamic_pager says that all it does is set the name and location of the swap files. There is an older version of the same man page that documents a -S option to set the size of the swapfiles created. I tried that, requesting 160 GB swapfiles, but it had no effect. The swapfiles were still 1 GB each, and the process was still killed by the kernel.

as per the photo attaches as an example. I wanted to recall how physical ram sums together. what types of memory go with each other to equal the sum total of the physical memory. (also in case of unified memory where gpu shares cpu memory since I have a M1 Mac) What would go in the used memory category? what would go in the available memory category? Where do these all fit in (App memory, active, wired, inactive, compressed, cached, free memory) (in case of M1 - GPU Memory). can anyone explain this, I dont need to know what the definition of each type of memory are I know all that. just want it in the photo example form since I feel its missing stuff.

My system (Yosemite / 10.10) has been paging out to swap memory despite my memory pressure reading less than 50% over the last 7 days (tracked with iStat Menus). How is this possible? It would be one thing if memory pressure exceeded 100% at some point in the last week and then the swap file was activated, but that doesn't seem to have happened at all and yet I've got 1.25 GB of 2.00 GB being swapped right now, with 36% memory pressure. Shouldn't the new memory model introduced in Mavericks behave differently?

I have a mid-2010 iMac running High Sierra. It has started getting very sluggish several times a week. I have tracked it down to the memory pressure and the process kernal_task. Shown below is a screenshot of the activity monitor when this occurs. As you can see the process kernal_task is using 9.43 GB of memory. This usually lasts 20 or 30 minutes. The kernal_task will occasionally drop to 5.46 GB and then sometimes down to 1.6 GB at which time the memory pressure is small and it turns green and my machine will return to normal. The next image is of the Activity Monitor showing CPU usage. Kernal_task is not using a lot of CPU but has been running for quite a while. Does anyone have an idea of what is happening? I've tried restarting my computer and quitting all open apps when it gets sluggish. Restarting the computer worked but eventually it gets sluggish again. Restarting every time this happens is a real pain. Quitting the open apps seems to have no effect. The final image below shoes the memory pressure when things return to normal.

I'm using VirtualBox 6.0.4 to run a Ubuntu 18.0.4 guest on a MacBook Pro 2018 host with macOS Mojave. The MacBook host has an i7 processor and 16GB of RAM. In addition to VirtualBox, I'm running Google Chrome. According to Mac Activity Monitor, the CPU is mostly (90%) idle. The virtual machine is too sluggish - whenever I drag a window across the screen it moves slowly, and rather than moving around the screen smoothly, it abruptly changes its location. Currently, the Virtual Machine has the following configuration: - 12 GB base memory - 6 processors - Acceleration: VT-x/AMD-V, Nested Paging, KVM Paravirtualization - 128 MB video memory - 3D acceleration enabled - IDE Primary Master: VBox Guest Additions I've read some suggestions here and in other forums, but I haven't found a solution that works. So far I've tried the following: - Installing VirtualBox Guest Additions - Installing VirtualBox Extension Pack - Increasing the base memory up to the maximum (valid) - Increasing the number of CPUs to 6 (from a total of 12) - Increasing the video memory to the maximum - Switching the graphics controller to VBoxVGA - Enabling 3D acceleration I've read that decreasing the number of CPUs and the base memory results in better performance, but I've tried this as well (and multiple other combinations) to no avail. Are there any settings that I should check which I haven't mentioned? If you have found a configuration "sweet spot," I would thank you if you could point me in the correct direction. **EDIT:** Below are a few screenshots showing CPU usage and memory pressure.

## Background In Super user, with an accepted answer : - **Disable** compressed memory in Mac OS 10.9 Mavericks?

I recently did a Yosemite (10.10) clean install on my 4 GB 2010 MBP, but it now has so much memory bloat due to unnecessary launch daemons/agents /services that it causes frequent beachballing; excessive memory pressure. This is **not a duplicate**; I did research manpage/docs on launchctl, launchd, Yosemite/Sierra whatsnew guides, AskDifferent, SO, Apple.com, many Mac enthusiast blogs/forums and many other sites for over a month now; see comments below for examples of the many Google keywords searches I tried; also, the answer is very MacOS-version-specific. This is driving me nuts. **I'm looking for a minimal configuration: no crap like iCloud, iTunes etc.** Just the absolute minimum set needed to run the OS. Clearly stuff like 'CloudPhotosConfiguration' is unnecessary bloat. (For reasons we will not go into here it doesn't make much economical sense to upgrade 8 GB RAM + SSD). **Question: How do I find out which launch daemons/agents/services I can safely disable on my mid-2010 MBP with 4 GB running Yosemite 10.10?** Activity Monitor doesn't show any obvious whales, although system memory usage when running Safari > when running Chrome. Below is a dump of which launchctl items had Status -44 (killed due to inadequate memory). Based on reading blogs, some are notorious (e.g. com.apple.bird), some are believed to be unnecessary, some cannot safely be stopped: clear; launchctl list | awk '($2 == "-44") { print $3 }' | sed -e 's/com.apple.//g' | sort -f com.apple. accountsd, AirPlayUIAgent, bird, CalendarAgent, CallHistoryPluginHelper, CallHistorySyncHelper, cfprefsd.xpc.agent, cloudd, CloudPhotosConfiguration, cloudphotosd, coreservices.appleid.authentication, coreservices.uiagent, DataDetectorsDynamicData, icloud.fmfd, iconservices.iconservicesagent, imdpersistence.IMDPersistenceAgent, InputMethodKit.UserDictionary, internetaccounts, MailServiceAgent, Maps.mapspushd, nsurlsessiond, nsurlstoraged, pbs, photolibraryd, pluginkit.pkd, printtool.agent, recentsd, secd, secinitd, security.cloudkeychainproxy3, soagent, spindump_agent, tccd, telephonyutilities.callservicesd

I am a web developer, and sometimes I encounter software bugs that has runaway threads or used up available memory in a browser process. Terminating the offending Chrome process will free up the memory usage, but kernel_task still use up a huge chunk of memory Running sudo /usr/sbin/purge does not make any impact on the used memory. How can I get kernel_task to free those unneeded memory?

After reading a couple helpful threads on this forum, I was able to figure out why my Mac started being non-responsive despite having 32GB of RAM, and almost nothing open. Despite using only 4GB-ish of RAM for applications, my Mac had almost 28GB of cached files. Since the system stops being responsive once it hits that point, I decided to take this PrintScreen a bit before I run out. How do I clear the cached files from RAM, to make sure I don't run out of memory when I'm using practically nothing? p.s., I have more than 1TB of available HDD space-- so it's not failing to store swap files.

Every time I turn my Mac on, after a while the app memory just runs out. These are just from 10min apart, after working for a while. I need help figuring what those Installers are and why the kernel_task is taking so much memory. Those Google Chrome Helpers also look extremely unnecessary. The only thing that 'solves' this is restarting the computer. How can I get rid of this cycle?

Mavericks' (and also Yosemite's) Activity Monitor shows a new diagram, the _memory pressure_. Sadly, its help text only vaguely explains what exactly it measures. How is memory pressure calculated? _Picture creds go to [this answer](https://apple.stackexchange.com/a/106071/12643) from a poll question on Mavericks' best new feature._

I've just upgraded my MacBook Pro from 4GB to 8GB. Before the upgrade, I looked in the Activity Monitor and it said that it was using almost 3.98GB of 4GB (I'm a web developer, so I usually have lots of apps open.) Then after the upgrade Activity Monitor shows that it is using about 7.50GB of 8GB (with the same apps opened.) The upgrade improved the performance of the Mac, it is surprisingly faster than before, but I was hoping to see more memory available after this upgrade. Thanks for your help!
