Mac Software no longer working on latest Mac Update Catalina

Post by adams161 » Sun Oct 13, 2019 12:18 am

As some know the latest Mac OS update Catalina or 10.15 no longer supports 32 bit programs. The popular ICC for Mac on chessclub.com that comes with built in Stockfish no longer works as of now. I've contacted chessclub and have not heard back yet so not sure on long term prognosis.

Lantern Chess continues to work on Catalina on ICC.

And Xboard for mac 4.91 also continues to work ( i've got it on fics now but icc is same software)

Other software that is 32 bit such as some engines are also not going to work now. Not sure if anyone is making an emulator to run 32 bit apps like a DosBox or something.
