Activity monitor CPU history now shows single graph in Floating window - how to restore display of all eight (8) cores?

Since restarting, the Activity monitor floating CPU history Window now shows all eight cores collapsed into one. This is NOT the behavior I expected after doing some research and finding this article OS X: Activity Monitor shows one CPU Usage graph on systems with more than four cores - Apple Support
Not a show stopper but I've been investigating performance issues on a new machine and this "new" behavior has me flummoxed and suspecting a newbie error.
Thanks!

Well, after a few more reboots and a therapeutic OS X 10.10.3 reinstall - troubleshooting some really sick performance issues. This problem has gone away. I am no longer staring a beachballs on my 8 core mini with 16GB RAM and an SSD boot drive. Should be good for a while :-)

  • I just bought my macbook pro and it's charged up to 100% and is still plugged in but now shows the battery at 98%.  How is this possible when it's plugged in to the charger and the green light is on?

    I just bought my macbook pro and it's charged up to 100% and is still plugged in but now shows the battery at 98%.  How is this possible when it's plugged in to the charger and the green light is on?

    The system regularly lets the battery drop to about 95% when on the charger, then recharges to 100%.  This lets the batery exercise "just a little" all of the time and saves the recharge curcuits from overuse.
    Regualr occurence for me.
    Also ... you need to let your battery work at least once per month.  Let it run down to 40%, but not less if you can at all avoid it.  Running thr battery fully dead will shorten the battery life significantly.

  • Activity monitor/CPU

    I was just wondering what "user"s listed i should be allowed to run under activity monitor within cpu and how to locate them in a file if i want to rid the usage from my macbook..i know that's kind of vague but i know as much about computers as the next guy..

    You really don't need to worry about it unless you get a runaway process and you will see that in CPU %. I normally keep mine showing All Processes to catch anything like this occurring.

  • My bookmarks used to be on the left side of the page like IE but now I have to open another window how do i get them back as part of my firefox page?

    I did something apparently to remove the list of bookmarks. I want them to always show on the left of the page.

    You can display the Bookmarks Sidebar by pressing Ctrl+b or using the View menu. If you have the orange Firefox button, first tap the Alt key, then
    View menu > Sidebar > Bookmarks

  • Confused about Activity Monitor CPU stats

    I have found at least one case where the CPU summary usage stats seem inconsistent with the per-process stats also posted.
    For example, I had noticed that under certain circumstances, the kernal_task was pegged at ~7.9% (only varying a few tenths of a percent) and yet the average "idle" CPU usage is consistently ~97 to ~98 percent (I would have expected ~92 to ~93 percent given that all but the kernel_task were pretty much idle during the observation period).
    Clearly, the summary averages are being calculated differently (over a different time scale???) than the line item process averages.
    This is not the pressing issue of the century .... still, I'd like to get a better idea of what these metrics mean.

    Let me guess ... if I've got 2 dual proc's it's 400% and 2 quad proc's it's 800% ????
    So the line item CPU stats are per processor, and the overall usage is calculated over 4 processors ?? (That roughly corresponds to seeing one task showing 8% loading ... but overall loading at 2% ... which is what I observed.)

  • I have an iphone 4s which I recently updated to iOS 7.0.4. Now my contacts no longer show addresses or notes, although the phone numbers are displayed. All the correct information is still in iCloud, but how do I get the Contacts folder to show all info?

    Since I updated to iOS 7.0.4 on my iphone 4S, I can no longer see addresses or notes in my contacts on my phone. The information still exists in iCloud online.  How do I get full contact info onto my phone?
    There is another problem which may be related.  My desktop computer at work is running Windows 7, and I was recently upgraded to Office 2013.  Outlook is not showing contacts on my computer any more, just in iCloud.  However, when in iCloud, it does included addresses and notes, so I don't think this is caused by the same error as the iphone problem,
    I have refreshed, reinstalled and rebooted, to no avail.

    I would say that you would want to look into the "Exchange Mode" for GMail.  That would allow your iPhone to sync calendars, contacts and email with GMail just fine.  Doing the same with your outlook should also then sync those same with your PC using Outlook.  I've done teh iPhone side of this, but I since I don't run Lookout for my email client, I'm not sure how that will work on the PC side.

  • In the new update, if i open a new tab, i see my history.... i DONT like that, how can i make it all go invisible or white like it used to be before the update?

    After update.
    Adressbar and favorits are missing. How to restore?

    * If the menu bar is hidden then press F10 or hold down the Alt key, that should make the "Menu Bar" appear
    * Make sure that the "Navigation Toolbar" and the "Bookmarks Toolbar" are visible: "View > Toolbars"
    * If items are missing then open the Customize window via "View > Toolbars > Customize" or via "Firefox > Options > Toolbar Layout"
    * If a missing item is in the toolbar palette then drag it back from the Customize window on the toolbar
    * If you do not see that item then click the "Restore Default Set" button to restore the default toolbar set up

  • IMac using 100% of the CPU, but no processes in Activity Monitor show usage over 3%. What's going on?

    This iMac is about 5 years old. It has the 2GHz Intel Core 2 Duo processors, 2GB RAM, and is running 10.8.5. After rebooting the machine, CPU usage is low. After about 30 seconds, when using Activity Monitor, CPU usage bumps up to 100% and stays there without budging. When viewing the CPU tab near the botom, % User is about 95+%, and % System makes up the other 5%. They change slightly every second. The problem is, if I sort my Processes by % CPU, the largest user is Activity Monitor with around 2.3%. Everything else is at 0.0%. So there's something weird going on causing the CPU to max out and run hot, but I can't figure out what's causing it. Checking for applications to force quit doesn't show any issues, and repairing permissions doesn't do anything. Is there any way to figure out what's going on? I read about how to reset the System Management Controller, is this something I should do? Thank you for ANY help, it's driving me crazy!
    EDIT: I figured it out! Browsing All Processes, I'm running a folding@home program, but I thought I uninstalled it! The process is called FahCore_a4. Is there any way to prevent it from showing up on boot? I want to get rid of it but I deleted the applications!

    Be certain to check that you are viewing "All Processes" as opposed to "My Processes"

  • Dual processor not showing up in Activity Monitor

    I have a dual processor G5 PowerPC at work and when I look at the CPU Activity Monitor it shows me the activity on both processors. My Mac Pro at home is also a dual processor but when I look at the activity monitor it only shows one processor thread. Is this normal or is there something wrong with my Mac Pro? Anyone else notice this as well?

    Hi KSStudio. A few questions to clarify.
    1. Is this a dual or single cpu machine?
    2. How many cores per machine?
    Check it out...
    Assuming you have a dual cpu (8 core) 2009 mac pro, when you use activity monitor choose > Window > CPU Usage. You should see a floating window with 16 panes. (8 panes if you have a single processor/4 core model) Under normal loads using 10.5 you should see some activity in all 16 panes. Under normal loads using 10.6 you should see activity in odd numbered panes. You will see activity in even numbered panes when the load is high. This is normal and due to Snow Leopard's improved utilization of processor technology.
    Hope this helps.

  • Activity Monitor problems increase CPU and power burn

    Migration Assistant worked very nicely, transferring from a Powerbook G4 with 30GB of files and data in about 45min via Firewire.
    However, after 2 days of usage, the CPU was still running at 80% and applications were incredibly sluggish. My battery calibration at full charge only showed a little over 1 hour. Activity Monitor also would not show any processes -- the list was completely blank.
    The solution was to rename the Preferences folder, allowing programs to create a new Preferences folder. I then selectively populated the new folder with the main old preferences for mail, Safari, etc. This not only solved the Activity Monitor problem, but immediately drove down the CPU usage to about 10% where I'd expect it. Now the battery shows over 2.5 hrs on a full charge with the screen on full brightness (and it's BRIGHT!)
    Also, Microsoft Word/Powerpoint/Excel/Entourage: trial software on the MacBookPro will mess up your migration, so delete the trial software BEFORE MIGRATION ASSISTANT.
    Hope this helps some of you out there!

    Another thing users who run Migration Assistant should know is that many of your background processes and helpers may slow down the Macbook.
    For example, I notice that a bunch of PowerPC menu items running under Rosetta slowed things down. Also, the Microsoft Office Autoupdate background process, which is started from System Preferences > Accounts > Login Items constituted one Rosetta process running all of the time.
    When I remove/disabled these background processes, I noticed a significant difference.

  • My airport doesn't manually shut down: airport icon is off, but activity monitor shows lots of packets still flowing. Its not my activity- all updates turned off. Virus?

    I'm running a Macbook Pro circa 2007 with OSX 10.6.8 and Firefox 27.0.1, and just had a circumstance that really puzzled me. I have a Hughesnet satellite modem with wireless router that I connect to via the airport, and I use Little Snitch software in the demo mode so I know and have to approve which software can send info through the internet connection., but the demo mode had just timed out and terminated and within a half hour of that the computer fans started speeding up to max and the CPU got blazing hot (+200 degF).
    Worried, I looked at the activity monitor and it was showing lots of internet activity even though I wasn't doing anything on the internet at the time, and I have all my software updates set to manual because otherwise they would use up my allotted daytime bandwidth and leave none for me. I'd already completed manual software updates during the nightly free time recently. Fearing my computer was hijacked & out of my control, I turned the airport off to terminate the internet connection, BUT IT DIDN'T TURN OFF, and though the indicator in the top right of the screen said it was off, packets were still streaming back & forth like crazy on the activity monitor, and the poor thing was still overheating. So I rebooted the computer, and when it came back up there was no internet activity, and things started cooling down, back to normal again.
     Though I'm no techie, this seems to me like my computer has been hijacked by some virus that has taken control of the airport and is feeding me lies about the internet connection status, so that it can use my computer for sending out its own messages. Has anyone heard of a virus that prevents the airport from being turned off, and what should I do about it? I'm afraid to back up my data with my time machine, though its been months since that was done, for fear I'd overwrite a virus-free state of the time machine files with a virus laden one, but I also hate to do something to clean up the machine without backing up my files, and lose a bunch of data. Is there virus protection software that could surgically search out and remove only the virus from my machine and leave most everything else untouched?
    Any advice is welcome,
    Christina

    HI and Welcome to Apple Discussions...
    Try Changing the Airport Channel
    Open AirPort Utility, located in the Utilities folder in the Applications folder on a computer using Mac OS X.
    Select the device you’re setting up, and then click Manual Setup. Enter the base station password if necessary
    Click AirPort in the toolbar, and then click Wireless.
    Choose a new channel from the Channel pop-up menu.

  • Activity monitor does not show processes

    When I run activity monitor it will not show any activity. Also, it does not show system memory, disk activity, or network. I think that the CPU section it not running correctly, either. Any suggestions.

    Nevermind..... I was using the activity monitor that transfered over from the powerbook!!

  • Activity Monitor not showing any processes

    See picture: http://bostonwebstudio.com/picture1.png
    Hello all, my activity monitor opens as it should, the bottom section works as it should, but the Processes list fails to appear, not matter which list I choose to show (My Processes, All Processes, etc.)
    Here's what I've done:
    - Booted from install disk and completed a permissions repair.
    - Booted from install disk and completed a disk repair.
    - Restarted the computer.
    - Slept on it.
    Nothing has worked; any ideas?

    Hi, Marc.
    Delete the word "Local" from the search field in Activity Monitor's tool bar: click the (X) next to "Local" in the search field and all should be well. There are no processes matching that search term, hence none are shown!
    Good luck!

  • Application Sudo listed in Activity Monitor - Is this a default app that should be running?

    First Question:        Do other MBP users have an application Sudo listed in Activity Monitor from start up of their mac or with typical use?
    Second Question:   If you have Sudo process listed in your Activity Monitor, do you also use an Huawei USB wireless modem?
    Third Question:       For those experienced in relevant coding domains and given the more technical details below - your thoughts?
    (Technical)
    Using MBP Retina, mid 2012, OSX 10.8.4
    I understand sudo is a unix root level access command. 
    I have used Terminal and become familiar with some basic unix commands, including using the sudo command in very limited single action command circumstances.  I have not used Terminal for many weeks, and the sudo command probably twice several months ago. 
    Sudo showing in Activity Monitor as an active process is to my understanding an entirely different situation to it being used in Terminal.  It appears the sudo process is being activated by some other application or process not of my direct use or actions.
    I remain a little concerned about this in view of the purchase of this particular MBP. It has a story to it. I was told this MBP was available as new on discount as it had been purchased by a man for his wife, the wife then left him, and subsequently he returned it unused to the store.   I was aware that there was a slim risk the laptop had been used for some other activities, and returned so any come back comes back to the new owner.
    I noted later with use that the MBP lower keys were sticky as if something has been spilt on them, so I do wonder if the laptop was previously used, then wiped, in which case the story presented to the retailer is likely not true and a more concerning scenario becomes possible.  
    All the same, I felt a clean install should remove any risk.  The MBP arrived in standard ready to set up and go mode, so OS loaded but no activation.  So it seemed a clean install to me.   I did not wipe the HD and do a fresh OS install from scratch. A decision I now regret.
    Some months after using this new MBP, my concerns were raised when I had one day of inexplicable internet usage on a wireless internet connection.  Not only did the level of data upload and data load, about 4 GB out of 20 GB for the month not make sense with actual usage, but also the MBP system logs did not tally with the internet providers accounting of usage on that day.  There have been two or three other anomalies in usage since.  The internet service provider reimbursed me on my evidence of OSX system logs.  Not sure if the service provider has people joy riding other users accounts or something suss this end was going on. Never resolved. The ISP was not exactly forthcoming, and I had to press hard to get some collaboration on resolve the anomaly of unexplained data usage.
    On the less suspicious side, the existence of this sudo program tracked down as in part coming from the install software from a Huawei modem provided by my internet provider.  However, while widely used and therefore likely not a security risk, I still feel need for some better explanation and resolution of the persistent sudo process. 
    I have  inquired to Apple Support about this sudo app running, and it apparently was not seen as an issue of concern by the front line support staff.  I took up some further concerns with them but checks indicate no issues of concern with the MBP from their assessment. I trusted that as fairly likely a definitive view, and so left the questions and anomalies as unexplained but harmless. 
    It is now several months later and I still find the existence of sudo as a running application or process in Activity Monitor troubling, and decided to try and resolve once again how typical and for what reason it is active on my MBP. Which brings us to this post.
    I have again spent a few hours searching on Google and Apple Support Forums.   All search results I find relate to the use of sudo as a unix command in Terminal to resolve a problem.  I can not find any indication of sudo as an app being open routinely in Activity Monitor with or without Terminal being opened or used.
    The only way I can think of to resolve if this is unusal or not is to get on this forum and ask the first two questions at the top of this post.
    More technical details follow.
    For some more technically minded the details may be of interest, hence below here I have added  details for further comment.   I am hoping some MBP users on this forum may also be coders, and hence have some idea of the internal mac coding environment. Enough to shed some light on this situation. 
    As mentioned, I think the sudo Activity Monitor may originate from the running of the Internet Providers USB Wireless Modem and software (Huawei E 169? modem).  The USB modem has the install software on it.  You install that software on your HD as an application. 
    On this USB Wireless Modem front I have done some checking.  
    Killing sudo in Activity Monitor does not stop an internet connection mid session. 
    When the USB modem is removed, the sudo process remains running and listed in Activity Monitor. 
    If I remove the Modem icon, unplug modem, close all apps, restart without the modem connected, the sudo process is still loaded and running in Activity Monitor.
    Months ago on a previous check if I deleted (uninstalled) the modem software, removed associated start up files installed by the modem installation, took out the USB Modem and did a restart, there was no return of the sudo process in Activity Monitor.  When the modem software was reinstalled or the start up files restored directly, the sudo process returns to Activity Monitor.  One of the software bits installed in start up files calls sudo (or so it appears having a peak in BBedit at the files.)
    This seems to fairly much establish the source of the sudo application. However it does not resolve why it needs to be open all the time, and if this is unique to this modem, my modem,  modems in general, or if permanent running sudo processes are fairly 'normal' in general.  Since sudo is a root level access process, I do feel a little concerned of the situation.   Let's say the sudo process is needed to initiate the modem under some justification.  Does the sudo process in remaining running permanently from there on, with or without the USB modem connected leave an open access way and vulnerability that can or is used later?   i do not know enough of the coding level architecture to form a view.   Still, seeing a permanent sudo process operating does niggle by sense of suspicion.    Hence, I continue to raise this issue and ask the questions I do.
    In Activity Monitor:
    sudo as a process when running is not very active.  
    Real Mem 8 KB, Virtual Mem 9.4 MB, Sent Msgs 75, Rcved Mesgs 26, Ports 25, Intel (64 bit).
    The sudo process:
    Using Sample Process in Activity Monitor:   sudo appears to be a running of the actual sudo command from within the unix command files.
    Path:            /usr/bin/sudo  (Master Library, not the one in the User files)
    Load Address:    (removed)
    Identifier:      sudo
    Version:         ??? (???)
    Code Type:       X86-64 (Native)
    Parent Process:  launchd [1]
    Call graph
    2nd line is 2656  start  (in libdyld.dylib) + 1  [(removed)]
    Binary Images:
    Includes reference to lots of .dylib files. eg libcache.dylib, libquarantine.dylib, libremovefile.dylib, libcompiler_rt.dylib, libcorecrypto.dylib
    The parent process is launchd[1]
    Process:         launchd [1]
    Path:            /sbin/launchd
    Load Address:    (removed)
    Identifier:      launchd
    Version:         ??? (???)
    Code Type:       X86-64 (Native)
    Parent Process:  ??? [Unknown]
    It seems all of the activity of launchd[1] is from the sudo process.
    Again reference to .dylib files as captured in call graph and Binary images.
    I hope the details are valued by someone with an interest to assist with resolving concerns.

    Thanks,
    I usually use the OS connection option. So as you suggest, connect without the ISP connection software.  Doing so does not by-pass the sudo command being active in Activity Monitor however. 
    On reading my post I see my failure to link the concerns of the laptop purchase with the sudo and modem. My thought here is of an intersection of known vulnerability with this widely used modem/software (via permanent sudo process activated) and that vulnerability then being known and utilised by another party(s).
    I am pursuing the issue in part with consideration to a broader possible issue of vulnerability.
    Thanks again for your thoughts and suggestions. Valued.
