The SMC (System Management Controller) is a component in Mac computers that manages hardware and system functions like power, temperature, battery, keyboard backlighting, and more. Fortunately, the methods we discuss below have worked for common errors (even if they weren’t among those listed in the last section). If we attempted to address all the error codes from a Mac that shuts down randomly, you’ll probably get tired of scrolling. However, it’s also possible that your system is throwing false alarms. Since extreme temperatures can damage your Mac’s components, it shuts itself off to prevent this. This code means that your battery temperature is too high. When a kernel panic occurs (due to overheating, file system errors, or software/hardware malfunction), it may have encountered a critical error that it can’t resolve. Your Mac’s kernel is responsible for managing processes, allocating system resources, and bridging software to hardware. It’s also possible that your system is throwing false alarms.Ĭode -64 indicates kernel panic. Your Mac may be overheating, and it shuts itself down in order to protect itself. This error code indicates thermal issues. Overheating may also cause CPU thread errors. It’s possible that there was an error in the execution of a specific thread that caused system instability or errors, leading to a shutdown. A CPU thread is a sequence of instructions that manage everything from interface responsiveness and event handling (for ex. We strongly recommend that you send it to a professional data recovery center to avoid further damage and permanent data loss.Ĭode 7 indicated a CPU thread error. your Mac is shutting down randomly), your Mac may be physically damaged. Rather, it means that your Mac was intentionally shut down using the power button or the Shut Down command in the Apple menu. This code does not indicate an error or malfunction. This may caused by a lot of things, like compatibility issues, configuration errors, or faulty software. Your Mac abruptly and intentionally powered itself off because it became unresponsive or encountered critical errors and needed a reboot to resolve the issue. This error code indicates a forced shutdown. To help you understand what each error code represents and how to fix them, we created a simple table that explains the most common codes with jump links to the appropriate solution. Those are error codes that give us an idea of the nature of the problem. You may see a bunch of numbers or negative numbers on-screen. Fortunately, there is a way to quickly narrow down the likely culprits using a simple Terminal command: log show -predicate ’eventMessage contains "Previous shutdown cause"’ -last 24hr
