CPU use Safari

Updated for Sierra. Noticed an excessive use of processors in MacPro when you use safari, interesting use is much less in the technology preview release. All solutions?

Hello MarkWithers,

If I understand correctly, looks like your Safari app uses more processing power that it should. I highly recommend the troubleshooting in the following article to help you solve this problem:

If Safari is slow, unresponsive, which closes unexpectedly, or has other issues

    First backup your drive hard as soon as POSSIBLE. You may well have a defect of the hard drives.

    Then start in the recovery volume (start with the command + R keys), select disk utility and run the feature of first aid on the disks.  If you receive a message that x number of errors were repaired, rerun the first aid until there is no errors detected and repaired.  Restarts normally and restart Etrecheck.

    Regardless of the results of the second report by no. means that you should not have Apple test a free diagnosis of your Mac.

    Thirdly, launch Safari with the SHIFT key is pressed and see if there is an improvement in the performance of Safari.

  • I have the same error message on Google &amp; Shaw and BC issues, but I also use Safari accessing google through Shaw is the problem with Firefox?

    The problem seems to lie between Firefox & Google talk to each other. I also use Safari as a browser, also liked to Shaw and don't have no problem with Google Mail, (cards and other sites which now belongs to Google.)

    This is caused by the network of Shaw, they are working on a resolution, but in the meantime the fix above will work. After Shaw solves their problem be sure to reset this value by default is that it is a safety device, you do not want allowed.

    Hello captainlarrydart,

    Thank you for using communities of Apple Support.

    If I understand your message that your Mac is apparently going to sleep on his own, sometimes immediately after waking up.  To help solve this problem, please follow the steps below.

    If your Mac goes to sleep in an unexpected way

    Make sure that this energy saver is set up as you wish: choose the Apple menu > System Preferences, and then click energy saver. Adjust one or more of the following affect when controls your Mac goes to sleep. Some of these controls are not available on your Mac model.

    • Cursor 'turn off display after.
    • Cursor "display sleep".
    • Slider 'the computer sleep.
      If a slider is set to 'Never', sleep is disabled for this feature.
    • Schedule button

    Make sure you that you do not put your Mac to sleep accidentally:

    • Pressing on the button / stop can put your Mac to sleep.
    • Move your mouse pointer into a hot corner can put your Mac to sleep, depending on your settings from Mission control. Choose the Apple menu > System Preferences, and then click Mission control. Click on the button active corners, then see if any of the corners are set to "Display Put sleep."
    • Using magnets near your Mac laptop can put your Mac to sleep.

    If the previous steps do not work

    These additional steps can help identify or resolve the problem:

    • Reset the SMC.
    • Reset the NVRAM.
    • Disconnect external devices other than your Apple keyboard, mouse, and screen. If that solves the problem, gradually reconnect your devices, testing each time until you find the device that interferes with sleep. And then check the documentation that came with the device or contact the manufacturer of the device.
    • Start in Safe Mode to see if the problem is related to startup items not Apple, login items or kernel extensions.
    • Try to isolate the problem by using a different user account.

    If your Mac does not sleep or wake up when expected

    Have a good.
