Which MAC OS are you using? Can you clarify the issue? are you not able to open the the eclipse?
If so, it can be a permssion issue, Please check:
1) go to eclipse/ezUsbSuite.app/Contents/MacOS
2) add the executable permissions (chmod +x ezUsbSuite)
If this does not help, please provide us a complete detail of the issue that you are facing (you can attach snapshots as well).
I followed your method to add the executable permission and re-installed Java SE 6 runtime from Apple. Now Eclipse works!
I am running macOS Sierra 10.12.2 on an Macbook Pro with 13-inch screen and touchbar.
Similar problem here --
I get a pop-up that says "To open “ezUsbSuite.app” you need to install the legacy Java SE 6 runtime." when I click on the eclipse icon. I can start the app from a terminal window by $HOME/Cypress/eclipse/ezUsbSuit.app/Contents/MacOS directory and typing ezusbsuite. (but it is very fragile ... lots o crashes) After installing legacy Java SE 6, I can click on the ezusbsuite icon and I immediately get the crash report window. Followed the permissions recommendations above, but there was no change (already had exe permissions) Any ideas?
OS version: 10.14.4
ezUsbSuite version: 1.3.4
