Hello,I am Pete, and I'll be happy to assist with your question today.
Hi Jeff, everything looks normal in Activity Monitor.
It would be worth just checking it again, immediately after a reboot, as soon as is practicable.
If there is still no unusually high activity then you can try reinstalling the Sierra OS:
To reinstall macOS, you must be connected to the Internet.
In the menu bar, choose Apple menu > Restart. As your Mac restarts, hold down the Command and R keys until the macOS Utilities window appears.
Select Disk Utility, then click Continue.
Select your startup disk on the left, then click Erase.
Click the Format pop-up menu, choose Mac OS Extended, enter a name, then click Erase.
Important: Erasing the disk removes all the information from the disk. Be sure to back up the information you want to keep to an external device.
After the disk is erased, choose Disk Utility > Quit Disk Utility.
Select Reinstall macOS, click Continue, then follow the onscreen instructions.
If there are any corrupt files in the start up disk then they will not be replaced if it is not erased first.
Hi Jeff, sorry for the delay in getting back to you, I did not see any notification of your replies.
The answer is.... it depends.
The startup disc should only be for your MacOS software and nothing else, so by erasing it you will only lose the operating system.
However if you have installed files and apps onto the startup partition (not best practice) then you will lose anything that is saved on it.
So it depends on where you have saved your files and apps - certainly make a backup of everything before performing this.
Thanks very much for the rating!
