MapCache 1.0 for Mac was available as a free download on our application library. The software lies within Developer Tools, more precisely Webmaster Tools. The actual developer of this free software for Mac is Kevin Hoyt.
From the developer:
Maps appear to be all the rage on the web these days. Google and Yahoo! seem to battle each other for features on an almost daily basis. But online maps have one shortcoming—you can't take them with you. This is where Adobe AIR comes in.
You may want to check out more Mac applications, such as MacCVSClient X, AcidSearch Installer or AlbumEnabler, which might be similar to MapCache.
