strange start.jnlp behavior

[oamber]

Im trying to access admin console from my MacBook, which Ive done for years from an icon on my desktop, and I can only get the IoX finder to load if I move start.jnlp to the download folder and start it from finder by control clicking and choose open. Otherwise I get this:

Caused by: java.io.FileNotFoundException: /Users/stevelittle/Desktop/start.jnlp (Operation not permitted)
    at java.io.FileInputStream.open0(Native Method)
    at java.io.FileInputStream.open(FileInputStream.java:195)
    at java.io.FileInputStream.<init>(FileInputStream.java:138)
    at java.io.FileInputStream.<init>(FileInputStream.java:93)
    at com.sun.javaws.jnl.LaunchDescFactory.buildDescriptor(Unknown Source)
    ... 5 more

plus, I cant at all if my MacBook is not on the ethernet. 

Any tips?

While I don't use Mac, it appears like there is a file association issue? Try clearing your Java cache, checking all 3 boxes and download a new start.jnlp from here: https://isy.universal-devices.com/start.jnlp

After the download, run start.jnlp and a new IoX Launcher should appear on your desktop.

Depending on which version of Mac you are running, there are a few troubleshooting steps in the wiki.

I did this, and it's the same. can only access IoX finder if the start is in the download folder. No changes to my situation. Possibly due to upgrade to OS Sonoma 14.0?

Thanks for the help!

@oamber not sure if this is new in an updated version of macOS, but see if this topic gives some insight for how to proceed. It seems that macOS doesn't like to allow Java apps from unknown sources. It just needs to be added/approved.
