This article is about Mac OS error code messages and what to do when one occurs. The meaning of various Mac OS error codes is available in Apple's developer documentation. These explanations are very technical and are often obscure descriptions of what happens when a system error occurs.
Error codes can be very useful to software programmers.
A programmer can interpret an error code to determine in what part of a program an error occurs, and how to resolve it. When system errors occur for non-programmers, error codes have less meaning. Some troubleshooting may need to be done to resolve the issue. In most cases you should simply restart the computer, and go on from there. In cases where the errors continue, some troubleshooting needs to be done to find the cause.
