MultiPatch is an all-in-one file patching solution. With this one program, you can apply BPS, IPS, UPS, PPF, XDelta, BSDiff or RUP (Ninja2) patches to files. You can also create BPS, IPS, PPF, XDelta or BSDiff patches. Everything is built in to the application natively, it is not a front-end and thus does not need to rely on external tools to accomplish the job. This program is compatible with computers running macOS 10.9 or later. Older versions compatible with Mac OS X 10.4 or later are available on the MultiPatch homepage.

MultiPatch uses several open source patching libraries under different licenses. The complete source code is available on GitHub. See the ReadMe file for more details.
