Kernel Panic - ACPI: Fatal opcode executed

Dealing with Kernel Panics

Disconnect any third-party peripherals including any USB hubs. Use safe mode to isolate issues with your Mac - Apple Support then boot the computer into Safe Mode. See Diagnosing problems- crash, freeze, panic, or spinning beach ball?, Don’t Panic! Understanding & Troubleshooting Kernel Panics in macOS, and How to fix kernel panics after installing OS X updates | MacIssues.

Kernel panics are indicative of possible hardware failure, so you should Check your Mac with hardware diagnostics or AHT. Read the kernel panic log: Mac OS X- How to log a kernel panic.

If you have no success figuring what is happening then you may need to examine the software you have running when the panics occur. Be sure it’s all current. If you must to resolve the problem erase the disk and reinstall macOS. Follow this outline to reset the computer to the factory-new state:

How To Do A Factory Reset

Selection A should be used on computers that came with Lion or later when factory new. These models had no disks included when new. Selection B is for Macs that came originally with Snow Leopard or earlier. These models shipped with Software Restore disks when new.

A. Factory reset of your Mac - Apple Support

B. Factory Reset Your Pre-Lion Mac

Follow these instructions until you get to Step 5 of Factory reset of your Mac - Apple Support. At Step 5 you will need a Snow Leopard DVD or the installer disc that came with the computer.

1. Boot the computer using the Snow Leopard Installer Disc or the Disc 1 that came with your computer.  Insert the disc into the optical drive and restart the computer. After the chime press and hold down the  "C" key.  Release the key when you see a small spinning gear appear below the dark gray Apple logo.
2. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities' menu. After Disk Utility loads select the hard drive entry from the left side list (out-dented entry - mfgr.'s ID and drive size.)  Click on the Partition tab in the Disk Utility main window.  Set the number of partitions to one (1) from the Partitions drop down menu, click on Options button and select GUID, click on OK, then set the format type to MacOS Extended (Journaled), then click on the Apply button.
3. When the formatting has finished quit Disk Utility.  Proceed with the OS X installation and follow the directions included with the installer.
4. If you are planning to sell or give your computer away, then do the following: After you reformat your hard drive and reinstall OS X, the computer restarts to a Welcome screen and asks you to choose a country or region. If you want to leave the Mac in an out-of-box state, don't continue with the setup of the system. Instead, press Command-Q to shut down the Mac. When the new owner turns on the Mac, the Setup Assistant will guide them through the setup process.

You encountered an illegal opcode in the interpreted language of the Advanced Configuration and Power Interface (ACPI).

Wikipedia describes that as "an open standard that operating systems can use to discover and configure computer hardware components, to perform power management by (for example) putting unused components to sleep, and to perform status monitoring."

This error tends to indicate you have some sort of Hardware issue, but it does not provide a direct indication of what that error might be.

It may to one of Apple's engineers, with your machine and a hardware debugger. Doesn't say much otherwise. If we are arguing, then you have provided some issues but nothing about their occurrences, errors, etc. You might as well have said, "My computer is broke. What do I do to fix it?" Furthermore, you state that you have a theory but do not say what it is. Oh, and it's not actually a theory but a hypothesis.

I can suggest you start by erasing the drive and installing a fresh copy of macOS, preferably the one that came factory pre-installed. If you continue to have repetitive problems, then document them thoroughly. Take the computer and your problem documentation to your local Apple shop for repair. You have to start from what should be a known state.

You only posted the first part of the panic report. Even with the entire report, it may not be conclusive.

Please post the entire report, by using the 'additional text' Icon on the forum:

--------

These system are very complex. For computer after 2013 model year, Apple provides the ability to load a field diagnostic by holding the D key at startup and waiting for it to load over the Internet.

You can also get a free evaluation of your computer's Hardware with the service diagnostic by presenting it at your appointment at an Apple-owned store.

At this point, you don't know whether your issues are caused by Apple Hardware or Apple software or things you added yourself. Your suggestion that this indicates Apple is sloppy are completely unfounded -- Apple stands ready to assist you..

Thank you for this. Ran hardware diagnostics and the result came back with 'no issues found'

I had some issues with my keyboard before the kernel panics. Had the keyboard and battery replaced by Apple.

They ran a hardware diagnostics test that showed no issues.

Any suggestions on what this may be?

Thanks

I am getting the same. Can anyone tell what this means.

Thanks
