How do I fix cpu panic and kernel trap issues on early 2011 MacBook Pro running Yosemite 10.10.4?

Over the last couple of weeks the dreaded CPU panic and kernel trap issues have cropped up causing my MacBook Pro to be virtually useless to me, as it keeps crashing.

System:

MacBook Pro (13-inch, Early 2011)

Processor: 2.3 GHz Intel Core i5

Memory: 4 GB 1333 MHz DDR3

Graphics: Intel HD Graphics 3000 384 MB

OS X Yosemite 10.10.4

It seems to have started after I installed the latest Yosemite upgrade one month ago. At first, the issue I was having was that periodically, the OS would simply switch users between my admin account and my iCloud account. I was seeing files disappear, or reappear, or deleted documents and/or software packages would reappear from iCloud, obviously, despite having been previously deleted. I was unable to resolve this issue and so I reinstalled OS X. The same issue developed with the even more frustrating issue of the keychain access constantly — relentlessly — interrupting my work. This was a frustration unique unto itself as the keychain is never used by me. But, despite this — keychain access had somehow migrated old and new passwords together — as though the old passwords had never been replaced.

After cursing the gods, I installed a Time Machine backup from late July and everything seemed fine. However, to my dismay, I am being revisited by the CPU panic error and kernel trap issues that I endured with this machine last summer. The issue is so severe that the machine shuts down during start up; it shuts down after the desktop opens; it shuts down if I open a webpage; it shuts down if I scroll down a webpage; it shuts down if I even dare to watch a YouTube clip. There is no situation in which it will not freeze and crash. Sometimes I get the dreaded three chime alert, other instances it just shuts off. Periodically, it shuts off only to restart on its own. Having read different threads on this subject I have previously used disk utility to repair disk permissions, repair disk, verify disk, etc. But even during this procedure I have had the machine shut off. What is so galling is that the machine states that all hardware is working normally. Unfortunately, after copying the last crash report sent to Apple, my machine shut off and I lost this info to paste here. What gives?

MacBook Pro, OS X Yosemite (10.10.4), 13-inch, Early 2011

I might add that after the Time Machine restore, when I began having the crashes, I reinstalled OS X Yosemite 10.10.4. So I am fairly certain that the problem is not due to some resident issue in the Time Machine back up that I used, since I have reinstalled Yosemite.

make backup of your startup drive, download OS X 10.10 from MAS one more time, make bootable drive with it, boot from this drive than erase startup drive in DiskUtility, install fresh OS X and use Migration Assistant for transfer files and settings

see if any changes with kernel panics

but start from EtreCheck report and login in to guest account

I am awaiting another crash to do just that. Yes, I have used guest account and have had it crash, so I know this is not an add-on (in fact, aside from Flash player and Skype, there is no other software besides OS X). I also know that having it crash under a guest user account it would imply that there is a hardware problem, but what?

Shouldn't I erase the startup drive first? If I download OS X 10.10 it will automatically install on the existing start up drive. I am confused about that point.

When you have kernel panics, the pertinent information is in the panic reports. The "etrecheck" stuff, despite what you've been told, is not pertinent.

These instructions must be carried out as an administrator. If you have only one user account, you are the administrator.

Launch the Console application in any of the following ways:

☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)

☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.

☞ Open LaunchPad and start typing the name.

In the Console window, select

DIAGNOSTIC AND USAGE INFORMATION ▹ System Diagnostic Reports

(not Diagnostic and Usage Messages) from the log list on the left. If you don't see that list, select

View ▹ Show Log List

from the menu bar.

There is a disclosure triangle to the left of the list item. If the triangle is pointing to the right, click it so that it points down. You'll see a list of reports. A panic report has a name that begins with "Kernel" and ends in ".panic". Select the most recent one. The contents of the report will appear on the right. Use copy and paste to post the entire contents—the text, not a screenshot.

If you don't see any reports listed, but you know there was a panic, you may have chosen Diagnostic and Usage Messages from the log list. Choose DIAGNOSTIC AND USAGE INFORMATION instead.

In the interest of privacy, I suggest that, before posting, you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if it’s present (it may not be.)

Please don’t post other kinds of diagnostic report.

I know the report is long, maybe several hundred lines. Please post all of it anyway.

When you post the report, you might see an error message on the web page: "You have included content in your post that is not permitted," or "The message contains invalid characters." That's a bug in the forum software. Please post the text on Pastebin, then post a link here to the page you created.

Make a "Genius" a ppointment at an Apple Store, or go to another authorized service provider. You may have to leave the machine there for several days.

Back up all data on the internal drive(s) before you hand over your computer to anyone. There are ways to back up a computer that isn't fully functional—ask if you need guidance.

If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to an empty drive from any of them.) Don’t erase the recovery partition, if present.

Keeping your confidential data secure during hardware repair

Apple also recommends that you deauthorize a device in the iTunes Store before having it serviced.

*An SSD doesn't need to be zeroed.
