Sorry, Ok, I have a MACH-O file and a crc file. There are other data files and when I try to edit them, It gives me an error whenever I run the program, So I'm trying to get rid of the checksum so I can edit freely.
Please explain what you are trying to do. CRCs are usually a part of executable files (and other files) so you know if they have been modified by someone/something. By you wanting to bypass them, does not sound kosher.
