Configure software and games (but be careful)
How do I open .cfg files on MAC
When you come across a file type that you (and your operating system) don’t recognize, it can be difficult to figure out how to open it. After all, every file has software that opens it, from DAT files in Windows to Office formats like DOCX or PPTX. Even files without extensions need the right software to open them.
A file format you may not recognize is the CFG file format, but what is a CFG file? CFG files are typically generic configuration files for other software, including applications and games, and are supported by Windows and Mac. Here's everything you need to know about CFG files (including how to open them).
The "CFG" in CFG file stands for configuration, which pretty much sums up its purpose for Windows and Mac users. CFG files are configuration files used by other software to customize how things work. Alternative file types, such as "CONFIG" for CONFIG files, work in a similar way.
