There are a couple of ways to install IBM Explorer for Z/OS on OS X. Both of these require running .app or .sh scripts as described in the Explorer download instructions.

The preferred way is to run but if you try to run .app it may require additional steps.

The first step is to allow the .app to run in the OS X Gatekeeper. Because the Installation Manager .app executables are not part of the Mac App Store, the Gatekeeper may prevent them from running. You may get the following error message: “” is damaged and can’t be opened. You should move it to the Trash. The Installation Manager support team issued a technote that describes how to make the Installation Manager .app run in the Gatekeeper.

Another step may be required depending on how your user account is setup in OS X. You may not have the authority to override the default Gatekeeper behavior to allow .app to run:

You can temporarily disable this restriction by opening the Terminal app
and running the following command:
sudo spctl --master-disable
Run the Installation Manager .app executable and don’t forget to turn the Gatekeeper back on by entering:
sudo spctl --master-enable

    Hello Gary,

    I’m a student – new to the IBM developer community. I’m trying to install the IBM RDz beta for mac to no avail. Any suggestions where i might begin would be much appreciated.

    I’m running OSX 10.11.6 which I’m thinking may be a problem.
    Many thanks in advance!

  2. So I’m trying to install this on a machine here and using the script to launch it. I ran the command as sudo so should have all the permission it needs. It gets the following error:
    “execution error: 2017-05-30 09:45:58.265 install[78430:3250346] Error loading /Users/Shared/aquamac/InstallerImage_macosx_cocoa_x86_64/jre_7.0.9040.20160504_1613/jre/Contents/MacOS/libjli.dylib: dlopen(/Users/Shared/aquamac/InstallerImage_macosx_cocoa_x86_64/jre_7.0.9040.20160504_1613/jre/Contents/MacOS/l/Users/Shared/aquamac/InstallerImage_macosx_cocoa_x86_64/jre_7.0.9040.20160504_1613/jre/Contents/MacOS/Users/Shared/aquamac/InstallerImage_macosx_cocoa_x86_64/jre_7.0.9040.20160504_1613/jre/Contents/MacOS/libjli.dylib: file too short (254)”

    Is there a fix for this?
