Installing SPROG DCC on Mac OS-X

Note: JMRI DecoderPro and therefore SPROG devices are no longer supported on Mac Classic or MacOS earlier than 10.5.8.

Mac OS X version 10.4 "Tiger" through 10.5.7 can only run JMRI 2.14.1, because that's the last JMRI version that can run on Java 1.5, the most recent Java version that's available on those Mac OS X versions. If you have "Tiger", you can download and install JMRI 2.14.1 via its release note.

Install Java

SPROG DCC devices use the JMRI DecoderPro software to run SPROG, program your decoders and manage all your decoder records.
