Q: 2011 mac mimi reboot

I have a Mac mini Server (Mid 2011), I7 with 16 GB memory, 2, 500 GB hard drive. Running OSX 10.11.5. The system restart by itself from time to time. Usually when I am using HDMI to watch a movie or when I transfer large files. Copying 1 or 2 GB files, usually work. when I get into 4 or 5 GB size, it may restart. The machine had been doing this for the past year or so. Took the machine in to Apple, no hardware error found. They told me it is software. Did a clean install of OSX 10.11.5, same issue. Reset SMC, reset NVRAM, same issue. Before I go in and just ask for a logic board replacement, what else would cause this problem?

Mac mini, OS X El Capitan (10.11.5)

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

    Please launch the Console application in any one 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.

    If you have an account on Pastebin, please don't select Private from the Paste Exposure menu on the page, because then no one but you will be able to see it.

    Hi Linc,

     

    There are no Kernel panic report on this issue. I can make the system reboot but no Kernel panic report generated. I am in the correct place. I see a .panic report from yesterday (I have a different problem with my USB drives. They are not connected, today), but, no kernel Panic report from 3 reboots, today. Is there some setting I need to change?

    This procedure is a diagnostic test. It makes no changes to your data. The instructions must be carried out as an administrator. If you have only one user account, you are the administrator.

    I've tested these instructions only with the Safari web browser. That's what I suggest you use, even if your preferred browser is something else.

    Please triple-click anywhere in the line below on this page to select it:

    syslog -k Sender kernel -k Message CSeq 'n Cause: -' | tail | awk '/:/{$4=""; print}' | pbcopy

    Copy the selected text to the Clipboard by pressing the key combination command-C.

    Launch the built-in Terminal application in any one 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.

    Paste into the Terminal window by pressing the key combination command-V. If you use another browser, you may have to press the return key after pasting.

    Wait for a new line ending in a dollar sign ($) to appear below what you entered.

    The output of the command will be automatically copied to the Clipboard. If the command produced no output, the Clipboard will be empty. Paste into a reply to this message.

    The Terminal window doesn't show the output. Please don't copy anything from there.

    May 30 02:28:34  kernel[0] <Notice>: Previous shutdown cause: -62

     

    above is what returned. It is interesting, it does not show the 3 reboots on June 1st.

    A negative shutdown code may indicate a hardware problem. The precise meaning of the codes is not publicly documented.

    If you haven't already done so, you can try resetting the System Management Controller. Otherwise, or if the reset has no effect, see below.

    Make a "Genius" appointment 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.

    Keep your confidential data secure during hardware repair.

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

    *An SSD doesn't need to be zeroed.
