Convert TAR.GZ to DMG

Understanding tar.gz and dmg file formats

tar.gz is a compressed archive file format commonly used on Unix and Linux systems. It combines multiple files into a single archive using the tar (tape archive) utility and then compresses it with gzip. This format is ideal for distributing software packages and backups.

dmg stands for Disk Image and is a file format used on macOS to distribute software. A dmg file acts as a virtual disk, allowing users to mount and access its contents as if it were a physical drive. It is the standard for macOS software distribution.
