Apple Mac OS 10.8.5 (Mountain Lion) and higher (from 10.9.5 through 10.13, High Sierra): With the release of OS X Mavericks 10.9.5, the way that OS X recognizes signed apps has changed. Signatures created with OS X Mountain Lion 10.8.5 or earlier (v1 signatures) will be obsoleted and Gatekeeper will no longer recognize them. For various versions of JSim, you may, upon running JSim for the first time, see the follow message: ' 'JSim' can't be opened because the identity of the developer cannot be confirmed'. You must change your 'Security and Privacy' settings to allow 'Applications downloaded from anywhere' to be run on the computer. Apple Mac OS 10.7 (Lion): By default Lion does not have Java installed. When starting JSim for the first time, a popup window will appear stating Java is not installed, and would you like to install it. If you click 'yes' Java will then be installed on your Lion machine.
After the Java install you will have to restart JSim. If you do not find the JSimmacos2xx folder on your desktop, check the configuration of your browser. If you use, you can find where downloaded files are saved by choosing Preferences from the Safari menu and clicking General. The Open 'safe' files after downloading box has to be checked.
If it is not, you should find a file named JSimmacos2xx.zip; double-click on its icon to create the JSimmacos file. JSim 2.07 and above requests 1500MB of heap memory by default. If your system has less than 2GB of memory, you will probably need to before JSim can launch properly. Most Macintosh users do not require running JSim from the command-line, which requires some additional setup.
If you do, do as follows (familiarity with Unix is assumed). Inside your installation directory, the sub-directory macos/bin contains the various programs in the JSim suite:. jsim: the JSim GUI application;. jsbatch: the JSim text-based batch application;. jsfim: command-line based functional imaging application;.
jsserver: the JSim remote server computational engine. You should either add this sub-directory to your PATH or copy the program suite to a path-searchable directory on your system. You must also set the environment variable JSIMHOME to the absolute path JSim.app/Contents/Resources (to the absolute path of JSimmacos for version 1.6.93 and lower) before starting one of these program. Consult a Unix tutorial (for example, ) to learn how to set environment variables.

(JSim version 2.17 and up) After unzipping JSim, double click the JSim app. If you do not have Java 1.8 installed then you may see an error message. Regardless, JSim will not open without Java 1.8 installed,.

Pick 'cancel', do not move to trash. This message is apparently caused by JSim's distribution of JavaApplicationStub be improperly signed. Normally, unsigned applications get a nicer message like: 'This app is from an unknown developer, go change your preferences to allow unsigned apps to be run'.
