Error code 1309 on Mac is a common type of macOS error that can show up on different occasions depending on what鈥檚 triggering it. There are many potential causes for the Error code 1309 message on Mac, so there are different methods to troubleshoot it.

There really is no single cause for this error, though there are several common factors that are typically responsible for its appearance. For instance, the 1309 error on Mac may be caused by a rogue app or even an app that鈥檚 simply not totally compatible with the current macOS version of your computer.

An accumulation of junk data and/or lack of free storage space may also sometimes lead to the error code 1309 appearing on your screen.

On some occasions, it鈥檚 also possible that a malware program in the system could be the reason for this error message. Though, in reality, this is rarely the case, it鈥檚 still a possibility that you mustn鈥檛 overlook.

Below, you will find instructions for each of those methods as well as for several additional ones. If you are experiencing the 1309 error, we suggest you try each of the shown methods until one of them works. Use your judgment to figure out which of the methods may be effective in your case and try that one instead of going through all of them. For instance, if the error is popping up only when you are starting a certain app, it is likely that there鈥檚 something about that app that is triggering the error message to appear, in which case you can try updating/reinstalling the app and, if that doesn鈥檛 work, you could delete it, and/or use the other suggested methods.

NVRAM is a part of your Mac鈥檚 virtual memory that is used to store different settings so that they can be accessed quicker. A problem with what鈥檚 stored in the NVRAM could be a possible cause for the 1309 error, and resetting the NVRAM may help fix the problem.

Method 6: Disconnect your peripherals

As we mentioned earlier, a problem with a peripheral device connected to your Mac may also be triggering the error. Try disconnecting everything (keyboards, mice, external hard drives, etc.), restart your Mac, and see if the problem is no longer present. If this works and the error is no longer showing up, you can start connecting the peripherals to your Mac one by one to see which of them is the cause of the error鈥檚 appearance.

SMC stands for System Management Controller, and it is a Mac subsystem that handles a number of important aspects of your computer that are mainly related to its power management and battery charging.

Therefore, we advise you to reset your Mac鈥檚 SMC if none of the previous methods have worked to see if this fixes the problem.

In case you are still not able to resolve the error 1309 issue, then it鈥檚 possible that there could be a malware program on your Mac that is triggering it while also (likely) performing other malicious activities.

It鈥檚 not excluded that a problem with your Mac鈥檚 RAM or hard drive could be responsible for this error. In this case, however, you should most definitely take the machine to a professional who can open it and take a look at its components in order to determine if there鈥檚 any hardware damage and fix it/make the necessary replacements.
