Signatures created with OS X Mountain Lion 10.8.5 or earlier (v1 signatures) will be obsoleted and Gatekeeper will no longer recognize them. If double-click launch does not work, see paragraphs below, Java install notes, or contact us.Īpple Mac OS 10.8.5 and higher (from 10.9.5 through 11.1, Big Sur): With the release of OS X Mavericks 10.9.5, the way that OS X recognizes signed apps has changed. To run JSim, open the JSim_macos_2_xx folder and double-click on the JSim application icon to launch JSim.Drag and drop the folder into the /Applications directory of your Mac computer. Folder may possibly be labeled macos_2_xx. After unzipping the JSim file, you should now find a folder called JSim_macos_2_xx (where 'xx' is the minor version number) on your Desktop (or in your Downloads directory).View complete license termsĭownload the current public release: 2.21 74.23 MB If you wish to receive news about JSim, please contact us. JSim now comes with Java JRE 1.8 ( Java 8 ).ĭownload the current public release of the JSim zip archive. JSim version 2.21 and above no longer requires separate Java Installation.

Apple quarantines apps that are downloaded from the internet but not copied from another computer on your network.

Another work around that has worked is to download the zip file on another computer and then copy it over to your Mac.

This uses xattr to recursively remove the quarantine flag from the JSim.app directory.

Next type: 'sudo xattr -dr /Applications/JSim_macos2.21/JSim.app'.

This gives read/write/execute privileges.

Now type 'sudo chmod -R 755 /Applications/JSim_macos2.21/JSim.app'.

Typically it is /Applications/JSim_macos2.21/JSim.app. One way to remove the quarantine attribute from JSim is through the use of the xattr command within a terminal window. There is no longer an override option for Gatekeeper on a case by case basis, to execute an application, not signed with an Apple developer certificate.

MacOS 11.6 ( latest update for BigSur): You can no longer download, install, and execute JSim on a Mac running MacOS 11.6.
