Pocket Soft has released RTPatch for Mac OS X. It’s an enterprise-level, native Mac software tool designed to reduce software application update size by sending only the changed bytes.
It supports Mac OS X 10.5-10.7. RTPatch works with programs and data. Compression is 100% lossless and typically results in 95+% reduction in update file size, says Bill Wise, CEO of Pocket Soft. Fully functional evaluation copies of RTPatch for OS X are now available upon request from Pocket Soft at http://www.pocketsoft.com .
