    memory mavericks activity-monitor memory-pressure
    Mavericks’ 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 from a poll question on Mavericks’ best new feature.

    software-recommendation command-line activity-monitor process
    I’m looking for a better alternative for top. Both top and Activity Monitor are highly limited with regards to features. In particular, I’m interested in the following features:Limit processes by name Send different kill-signals to a process interactively, i.e. select the process from the process list and send a signal Ability to show the entire command, not only the program name (as top -c does on Linux) Show the status of each process Optional: On Linux, top also updates the command when displ

    ipad memory-leaks memory-allocation instruments activity-monitor
    I am helping a friend hunt down a crash in an iPad application he has written. The application is pretty straightforward, transitioning between UIViews under a single UIViewController as the user goes forward and backwards through pages. The crash is pretty hard, and doesn’t drop us in the debugger or anything- the app just dies. In the console the infamous ‘signal “0”‘ message is posted, which according to this question is most likely due to the OS killing the app over memory consumption.The me

    ios memory-leaks activity-monitor
    I am debugging an iPhone app that was written by someone else, it doesn’t use arc. I have tried using arc but they have a lot of old code that uses some c style void pointers, so the program crashes when I do.I have given up on that idea as a lost cause. The problem is that the allocations / leak tools don’t show a memory leak, but the Activity monitor shows memory being leaked every time the user swipes to change a page. (about 1.5 Meg each swipe) Needless to say the program crashes.Being a c+

    google-chrome mavericks activity-monitor
    I upgraded to OS X 10.9 yesterday, and since then, one Google Chrome Helper is constantly red in Activity Monitor. I checked the PID (375) in Google Chrome’s own task manager, and it is GPU Process. I don’t think it is used often, but I also fail to see why it is constantly non-responsive.Does anyone else experience the same thing? Is this a problem of GPU handling of the new OS? Maybe there are some GPU-accelerated websites/videos (I mean video player) out there so I can test whether there is a

    snow-leopard battery activity-monitor
    Just recently I noticed my battery life having a pretty significant drop and the “kernel_task” process using quite a bit of CPU (a constant 1-6% on my 2.8ghz dual-core i7, 2010 MBP). Obviously I think the kernel_task’s CPU usage is contributing to the battery drop and I need to find out why.Searching Google, it seems kernel_task is OS X’s version of Windows’s “svchost.exe” – the notorious do-everything process that you can’t ever truly debug, you have to just manually flip switches until one of
