Thank you for contacting us.
As I understand from your description, you’ve already tried to uninstall the ISS using the uninstall file using the Administrator password from step 3 here: https://software.intel.com/en-us/intel-system-studio-iot-c-installing-on-mac ,is this correct?
Have you tried to uninstall the program by moving its contents to the trash? I’ve previously uninstalled software on Mac just by dragging the software and all of its related system files to the trash.
Try using this approach and let us know your results. Please send us pictures of the process so we can review the steps you’ve taken.
We’ll be waiting for your response.
Would you please share pictures of the error you receive after trying to uninstall ISS? We ran the uninstaller and it seems to have deleted all files associated with the ISS.
As an alternative, you can also try to run another uninstaller software. There are a few free uninstallers for Mac that should be able to help delete the remaining libraries. You can try the options listed here: http://www.macworld.co.uk/how-to/mac-software/how-delete-apps-on-mac-how-uninstall-software-applications-in-macos-3463412/
Let us know your results.
