What Do System Error Messages Mean?

It is true that Macs are extremely reliable machines that rarely fail to live up to even the most stringent expectations of their users. However, on rare occasions, even a new and shiny Mac can stumble and surprise its owner with a cryptic error message. Although system errors are extremely scarce occurrences, Apple users should know how to properly interpret them.

The knowledge of the most common system error messages helps to resolve many performance issues, thereby allowing them to make the most of their macOS-based devices. If an error occurs, it means that there’s either a hardware conflict or software failure that makes the execution of certain instructions impossible.

The article has been written to help Mac owners who run into the system error codes to understand what they mean. It also explains what can be done to resolve the underlying issues that lead to the occurrence of the error messages.

Interpretation of System Error Messages

The following is the interpretation of the most common system error messages.

Type 1 Error (Bus Error)

Type 1 error occurs when a user tries to access physically inaccessible memory. In other words, the memory access violation happens when a non-existent address is not recognized by the system. To solve the underlying issue, it is necessary to allocate more memory to an app or operation that is being executed.

Type 2 Error (Address Error)

Just like type 1 error, type 2 error occurs because of a memory-addressing failure. A failure that falls into this category of system errors is an attempt to access data that is stored somewhere else in the memory. Another cause of type 2 error is the inability to read data from an odd address. A user is also presented with the error message if their CPU doesn’t support certain instructions such as 030 request. A solution for type 2 error is to allot more memory to the attempted app.

Type 10 Error (Line 1111 Trap Error)

The error happens when a user tries to execute an instruction unsupported by their CPU.

Type -36 Error (I/O Error)

The error is a sign of an improperly written data. In most cases, the error indicates that a hard drive is damaged. To correct the error, a user should copy the file, which cannot be opened, to another drive. It is also necessary to examine the drive with the help of a disk recovery utility. Regular backups substantially increase the chances of restoring the file in question.

Type -39 Error

The occurrence of type -39 error means that a Mac cannot find an end-of-file marker while executing a read operation. The system cannot locate the file because it is either missing or stored in the wrong location. The error can also be caused by a disk crash or a corrupted file. To solve the problem, try recovering the corrupted file. If it doesn’t help to resolve the issue, make a backup clone and use the Import command. Another way to eliminate the error is to move the file in question to another disk volume.

Type -43 Error (File not Found)

The error indicates that a user tries to access a file that is missing or stored in the wrong location. In most cases, the trashing of the Claris XTND translator resolves the issue. The translator is located in the Preferences folder of the System folder.
