While Apple's handling of this has improved in Mavericks, Safari appears to keep some content in memory for later use. You usually see Safari Web Content high in this list, reflecting ads and other media found on sites you visit. To check system memory, click Memory - you'll see which of your tasks are eating up memory and how complex those tasks are (by threads used). Such information can help you identify potential problems before you hit a wall. Use this to determine which of your apps/processes are using much Virtual Memory. This will show you how much data is being written to and read by your disk. To get an idea as to the health of your drive, tap Disk. You can use these tools to understand how busy your system is, how much real and virtual memory it is using, track how much Energy apps are using and track things like the size of the file cache or network activity. These change when you click the select one of the tracking items (CPU or Memory, for example) in the top of the window. To find a little more about any column heading or statistic just move your pointer over the item and leave it there, tool tips will appear with more informationĪt the bottom of the application window there's a series of diagnostic windows. You can ask Activity Monitor to track other items within the View item in Menu bar, but we won't be looking at these today. You can click on any column to list items in order - that helps identify applications or processes munching memory, for example. User: OS X can be its own user for essential system processes - "root, while user-generated processes like using apps are denoted by Mac user name. PID: A number assigned to each process by the computer Idle Wake Ups: Number of times a process causes the system to execute a task Threads: How many instructions a process is running %CPU: How much processor power that process is using ĬPU Time: The length of time a process has been running Various active processes and applications are listed by name alongside the following: So adjust the highlighted index in the above line accordingly if needed.The section beneath these controls provides you with more detailed perspective. The columns are numbered from the leftmost, starting at 1. I'd dragged the PID column to the leftmost position so on this line, I had to change the index to 1 : set pid to value of text field 1 of aProcess This applies if you've ever dragged the PID column in Activity column to a different position. In absence of that icon (I haven't confirmed in older macOS versions), I believe the CPU etc buttons would be in group 1 of toolbar 1 In macOS 10.12.x, the toolbar contains an additional icon due to which the set of buttons (CPU, Memory, Energy, etc) are in group 2 of toolbar 1 instead of group 1 of toolbar 1. If pid is not "" then do shell script ("kill -9 " & pid) Set pid to value of text field 1 of aProcess - ( **2 ) For each non responding process retrieve the PID Set notResponding to rows whose value of ¬įirst static text contains textToSearchForInProcessName Tell outline 1 of scroll area 1 of window 1 Make sure View -> My Processes is selectedĬlick menu item "My Processes" of menu 1 of menu bar item "View" of menu bar 1 Repeat until (exists menu 1 of menu bar item "View" of menu bar 1) Wait for the Activity Monitor window to open Tell application "System Events" to tell process "Activity Monitor" Tell application "Activity Monitor" to activate Set textToSearchForInProcessName to "Not Responding" This worked on 10.12.6 and is a minor modification of the original script (saw comment after I'd done my own investigation): (Posting this as a separate answer since too long to fit in a comment)
