Serialbox is finally a Tool running on the Macintosh that is offering you a huge selection of serials exclusively for the Mac Platform.

The new builds of iSR don't support 10.4 anymore. This is an older build with the latest security certificate that opens sb2 files on 10.4. I will not fix feature bugs in this build any longer, just keep the security certificate up to date for as long as possible so it opens the files, and if I have more time work on the main build.
