GuancheMOS is a serial number creation/validation machine plug-in compatible with applications developed with REALBasic 5.x or later as Carbon, Mach-O, Universal Binary, Win32 and Linux executables.
GuancheMOS allows REALbasic Mac developers to include in the applications the ability to generate and check unique serial numbers or license keys with a minimum effort and a minimum footprint in their executables.
By using this plug-in, REALbasic developers will be able to build a program automated assignment and control of serial numbers in a per-application basis, and integrate the serial validation process in their own projects and final products with the simple call to a function.
TVALLEAU Good software with a responsive developer. Although I've not seen an update in a while (thanks!) when I did need to contact the developer a while back, I recall that he responded promptly and courteously. As to the software, it works just fine. (Version 1.7)
