Mac OS X Sierra 10.12.6 Freezing issues

I have a mid 2014 15 inch retina display Macbook Pro. The problem is getting worse and worse. Just recently I upgraded from El Capitan and at first I had no issues. But now my computer has been freezing (everything frozen) whenever I use anything. I have to restart the computer but just about a minute after I restart the Computer freezes again. It is really frustrating because I cannot do anything. I had to use Windows Boot camp to be able to write this.

I have tried doing a restart while holding D, but my computer said I required an 85W charger, not a 60W.

Anything helps

Thanks

Have you tried resetting the SMC and PRAM? If that doesn't fix your issue, if you have any time machine-backups, restore to one of those backups, and see if the computer still freezes.

EtreCheck is a tool that helps Apple Support Community volunteers debug problems without any access to the troubled computers. Debugging problems can be a difficult task even when the machine is in front of you. Attempting it via a discussion forum is extremely difficult. EtreCheck is a great help that regards.

This helped for a bit, I had no issues and the freezing went away. But now my computer just randomly restarts and displays the error message "Your computer shut down because of a problem".

The problem got really bad, and the computer would either freeze or crash with anything. I ended up wiping the whole computer, and a day later it continues to crash.

Would you be interested in posting the requested EtreCheck output?

Also if you have been crashing, could you please post the panic report (posting a couple of the panic reports will show whether or not it is the same cause or not)

Kernel Panic reports: Finder -> Go -> Go to Folder -> /Library/Logs/DiagnosticReports

<https://support.apple.com/kb/ht2546>

<https://support.apple.com/en-us/HT200553>

The panic report should have "panic" in the file name.

There are no panic reports in that folder.

There is nothing obvious in your EtreCheck report.

I will mention that Chrome is a resource hog, but it should not cause what you are experiencing, unless you have tons of Chrome tabbed windows open concurrently when this happens.

I would suggest booting into Safe mode as an experiment to see if you get the same behavior

<https://support.apple.com/kb/ht1564>

This will not load any 3rd party additions, it will load some more conservative Apple drivers (may cause screen flicker), and it will clear some kernel caches (a cache is saved data in a form that can speed up a program, but is totally redundant to the original source, and thus can be safely cleared).  Booting into Safe mode is just an experiment, but can often times eliminate any 3rd party interference, or a cached item out-of-sync with the world.
