What is DiffMerge?
DiffMerge puts two text files side by side so you can inspect changed lines and individual characters, then edit the result. Its three-way merge view helps combine changes from different file versions, with automatic merging where possible and manual editing for the remaining decisions. Folder comparison identifies matching files, changed pairs and files present on only one side.
This entry links to SourceGear's 4.2.1 Intel DMG, whose filename identifies build 1013. The publisher lists OS X 10.6 or newer and documents Intel 32-bit and 64-bit executables; that historical minimum is not confirmation of compatibility with current macOS releases or Apple Silicon. No installation or runtime compatibility check was performed.
DiffMerge is licensed for use free of charge under SourceGear's proprietary license. Paid registration is optional; unregistered copies occasionally display a registration prompt.
