Simply enough, JAVACMD in cogtoolstart could be updated to the new java location, which for me was JAVACMD='/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home/bin/java'.Īfter this, I could open CogTool from the Applications folder as normal. The next issue to solve was that CogTool was trying to open the default java (JRE 9 for me), which I didn't want to overwrite, as it's used elsewhere. It seems like it might have been deprecated?Īfter a bit of searching I found that JRE 1.6 (aka JRE 6) is basically backwards compatible with 1.5, and there's a version that installs on my machine: 'Download Java for OS X 2017-001 '. I had some difficulty finding a JRE 1.5 that worked for my version of Mac. JAVACMD='/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home/bin/java') Edit /Applications/CogTool/Contents/MacOS/cogtoolstart so that JAVACMD='/path/to/your/java' (e.g.If you double click cogtoolstart, a Terminal window opens showing the usage instructions for java, which you'd expect might happen if opening the wrong version. If you explore the contents of the app (right-click and select 'Show Package Contents') then open Contents/MacOS/cogtoolstart, you can see that opening the app tries java 1.5, then if that doesn't exist, just tries the system java. I had Java Runtime Environment (JRE) 9 installed on my High Sierra Mac, but when I tried to open CogTool nothing happened: the icon would bounce a couple of times to say it was opening, then disappear.

CogTool assumes JRE 1.5, which can't be installed on the latest Macs (and the latest JRE is not compatible).(I'm not particularly familiar with the Java ecosystem, wherever I mention the 'Java Runtime Environment' (JRE), the 'Java Development Kit' (JDK) may be more appropriate) Problem
