Realmac Software on Friday sent a note to its customers confirming that the company was ready for Apple’s upcoming Mac OS X Snow Leopard release. In fact, Realmac released an update today for LittleSnapper, its digital scrapbook for designers. In addition to several fixes and improvements, LittleSnapper 1.5.1 adds full support for Snow Leopard.

However, the app that many are wondering about is RapidWeaver, the company’s popular Web site design application. Realmac issued a release candidate of RapidWeaver 4.3, which offers compatibility with Snow Leopard.

While the release candidate is not the finished release, it has been in testing for a while, so users should have very few, if any problems. Realmac expects to release the final version shortly after Snow Leopard ships.
