Visit Krypted.com and the Carnegie Mellon University website to learn about the different Mac error codes. You can also learn about common error messages and how to resolve them at MacWorld.co.uk, as of November 2015.
Mac error codes fall into several categories, such as general errors, memory manager errors, sound manager errors, speech manager errors and dictionary manager errors. Some error codes under general errors include -34, which means the disk is full; -45, which means that some file is locked; -43, which means that some file couldn't be found; and -48, which means that there is some file in the same directory that has the same name.
Memory manager error codes include -110, which means that an address is odd or out of range; -112, which means you are trying to purge a non-purgeable block; and -108, which means that there is insufficient room in the heap zone. Sound manager error codes include -212, which means that there aren't enough CPU cycles left to support additional tasks; -220, which means that there isn't any sound input hardware; and -227, which means that the input device is already in use.
Dictionary manager error codes include -413, which means that the operating system can't allocate disk space; -414 which means that some record already exists; and -415, which means that some record can't be found.
