Newest build - Won't open on Mac OS X

[fredward]

You need to start the emulator manually by running the Java interpreter.

I use the following shell script:

#!/bin/csh -fe
set curr_dir = `dirname "$0"`
cd "$curr_dir/Jpcsp.app/Contents/Resources/Java"
java -Xmx1024m -Xss2m -XX:MaxPermSize=128m -XX:ReservedCodeCacheSize=64m -Djava.library.path=lib/macosx -jar bin/jpcsp.jar

Create a text file with this script. Save it in the same folder where you installed "Jpcsp" then left-click the file and "Open With" -> Terminal

Works great in Yosemite 10.10.2 but for some reason is not using all CPU cores.

I'm having the same issues as well. I am running Mavericks. Can you explain setp by step to get it to work?
