Cannot attached media with Virtual Console

Using IDRAC 7 Virtual Console , I cannot attached media using the "Launch Virtual Media" menu option. The virtual media windows appears for about 1 second and disappears. In the brief flash I can tell that it see the Firmware update disk that I have mounted on my Mac  but I cannot use it since the virtual media window isn't functional.

• Workstation OS ( Mac OS Sierra 10.13.1 ) ,
• Java version: Java 7
• Browser: Chrome 66
• iDrac firmware: Version 1.30.30
• PowerEdge Gen 12: R720xd

I read that Java 6 and 7 are supported, so I installed Java 7 plugin for Chrome 66. 

The first error I hit was the login error. I was able to get past that by hard-coding the idrac credentials into the .jnlp and relaunching the app. 

Error:

After that, the console opens and I can see the remote console of the Dell server.

Error that occurs every time I launch virtual media. 

I have vFlash but the upgrade ISO file is 4GB and that only supports 2GB partitions. 

Any advice on either fixing the virtual media issue or an easier way to *remotely* upgrade the IDrac would be appreciated.
