MacBook Pro Spontaneous Reboots

My wife and I both have MacBook Pro mid-2010 model laptops. In the last year they started spontaneously rebooting once in awhile. This has gotten especially bad in the last few months to the point where some days you can hardly get any work done. 

There is no consistent set of circumstances that seem to trigger it. Very often we’re browsing in Safari, but it has happened while trying to print a very simple text document from Textpad or while in Pages. 

Mine is an 2.66 GHz Intel Core i7. Hers a 2.4GHz Intel Core i5.

Both computers are maxed out with 8Gb of RAM. Mine is running Sierra 10.12. Hers El Capitan 10.11. 

Repeated google searches have come up with no definitive answer. A suggestion was to disable graphics context switching (as I recall from memory as my computer is rebooting again and I’m typing this on my phone). I did. No difference. 

One link I found suggested the issue is a resistor on the mother board which would be a perfect ifixit project. 

Hoping someone has some idea. Apple of course is no help whatsoever.

BTW, this is a very widespread issue. Many people are complaining about in various forums. If anyone can come up with a fix you would benefit many people and help folks avoid trashing an (almost) perfectly good computer to buy a new one

You’ll need to start with the basics, installing a good anti-virus and malware apps making sure you haven’t been compromised. Make sure you do a full sweep of your drives (all)

  • Open up Disk Utility to make sure you don’t have a Trojan image download trying to install. I’ve seen that a few times.
  • Disable update services both the Software Update and Apps Update. I find they often will fire off when you least want them too.
  • Review your log files do you see a pattern?
  • Reduce your application auto load under the user accounts.
  • Clean your drive off free up at least 1/4 of the drive as free space. If you have HDD’s you’ll need to de-fragment the drives as well.

You notice there is nothing hardware-wise listed here. I doubt that is your issue,

I would still check the health of the systems battery as being a 2010 system with the original battery would be pushing it! Install this gem of an App CoconutBattery with the charger plugged in take a snapshot of the apps main window and the battery info pane. Post the images here for us to see for each system (clearly mark which system has which set of images iFixitでの質問に画像を追加する方法
