Vote for a Mac edition of RDi
Rational Developer for i (RDi), the modern editor for IBM i RPG, COBOL and other languages, runs on Windows and Linux, but not Mac.
IBM has shown some willingness to port the product to Mac. They have posted a poll to allow users to vote for this enhancement or to comment on the proposal: https://www.ibm.com/developerworks/rfe/execute?use_case=viewRfe&CR_ID=13454
Those wishing to vote will find a “vote” link near the bottom of the poll page.

The poll has been removed, so it’s possible that a decision has been made. I’ll ask about it at COMMON.
Alan, what did you find out at common?
Chris, I didn’t find much about RDi for Mac at COMMON, but for what it’s worth, later in the year I read a posting by Jon Paris (on his Facebook page): “Finally found out from IBM the other day that one of the major inhibitors to running #RDi natively on Mac is that they exploit features of the IBM JVM. And there is no IBM JVM for Macs.”
Thanks for the post Alan!
The big hang up has been on the verifiers I believe. If IBM was ok with the lack of verifiers a product could be brought out quickly and the verifiers added later.
