Question

Is there a Mac OS X application that's similar to Beyond Compare (for Windows)?

Answer 1

Perhaps the free merge tool Apple provides with Xcode will do enough of what Beyond Compare does for you. It's called file merge.

It can do two way and three way file comparisons, the merging of changes, and directory comparisons and synchronization. It does not have specialized viewers for stuff like ID3 tags and images.

Answer 2

I use KDiff. It's not as pretty, but has quite a few features for compare and merge. I like it a lot. A Mac version is available, and is also available for Windows and Linux. It is free and open source.

Answer 3

DeltaWalker by Deltopia (http://www.deltopia.com/) gets high praise by BC users using Mac.

Answer 4

I use Araxis Merge, it's pretty good (on both Windows and Mac): http://www.araxis.com/merge%5Fmac/index.html

It can diff pictures too.

Answer 5

The Perforce merge utility (P4Merge: http://www.perforce.com/perforce/products/merge.html) is another alternative that's available for free. It is a good option if your mostly diffing source code revisions (it can be chosen as the default graphical diff/merge tool for scms like git, mercurial, and subversion).

Hopefully scootersoftware will release a mac version in the future. That would make BC the ultimate cross-platform diff/merge tool.
