Macbook Pro running hot and freezing up

When I open the Macbook, iCloud pops up for me to login, but won't accept a login. When I cancel it, the login box appears again. When I cancel it a second time, it disappears. Within several minutes of starting to use Safari or Chrome, the computer freezes and heats up. It does not happen in Safe Boot.


I've reset SMC and PRAM. Resetting SMC seemed to help for half a day then the problem resumed.


The most recent time it started to heat up on 2/24/15 at 09:52:50 PM, Activity Monitor showed that Google Chrome Helper was using CPU at 100%. I followed Linc Davis' instructions with the following output in Console:


2/24/15 9:51:16.961 PM Google Chrome Helper[540]: CoreText CopyFontsForRequest received mig IPC error (FFFFFFFFFFFFFECC) from font server

2/24/15 9:53:18.279 PM com.apple.xpc.launchd[1]: (com.apple.quicklook[575]) Endpoint has been activated through legacy launch(3) APIs. Please switch to XPC or bootstrap_check_in(): com.apple.quicklook

2/24/15 9:53:18.571 PM Console[217]: Failed to connect (_consoleX) outlet from (NSApplication) to (ConsoleX): missing setter or instance variable


I saved this to a TextEdit file, and doing so caused the computer to freeze so I could not run the Terminal diagnostic test suggested by Linc Davis in other posts. I have run this diagnostic test at other times recently and can post one if that is helpful.

Done. Here is the output. In case this is helpful, I booted in normal mode and the cpu went to 100% on 9/26/14 at 21:24:13. The computer shut itself down. I rebooted in safe mode and ran this diagnostic.

Remove "K9 Web Protection" and see whether there's an improvement.

Any third-party software that doesn't install by drag-and-drop into the Applications folder, and uninstall by drag-and-drop to the Trash, is a system modification.

Whenever you remove system modifications, they must be removed completely, and the only way to do that is to use the uninstallation tool, if any, provided by the developers, or to follow their instructions. If the software has been incompletely removed, you may have to re-download or even reinstall it in order to finish the job.

I never install system modifications myself, and except as stated in this comment, I don't know how to uninstall them. You'll have to do your own research to find that information.

Here are some general guidelines to get you started. Suppose you want to remove something called “BrickMyMac” (a hypothetical example.) First, consult the product's Help menu, if there is one, for instructions. Finding none there, look on the developer's website, say www.brickmymac.com. (That may not be the actual name of the site; if necessary, search the Web for the product name.) If you don’t find anything on the website or in your search, contact the developer. While you're waiting for a response, download BrickMyMac.dmg and open it. There may be an application in there such as “Uninstall BrickMyMac.” If not, open “BrickMyMac.pkg” and look for an Uninstall button. The uninstaller might also be accessed by clicking the Customize button, if there is one.

Back up all data before making any changes.

You will generally have to restart the computer in order to complete an uninstallation. Until you do that, there may be no effect, or unpredictable effects.

If you can’t remove software in any other way, you’ll have to erase and install OS X. Never install any third-party software unless you're sure you know how to uninstall it; otherwise you may create problems that are very hard to solve.

Trying to remove complex system modifications by hunting for files by name often will not work and may make the problem worse. The same goes for "utilities" such as "AppCleaner" and the like that purport to remove software.
