EV3 Software hanging on start-up - macOS

[plingboot]

I wonder if anyone can help with a problem I'm having?

I bought an EV3 brick, second hand from ebay - I downloaded the EV3 application from the Mindstorms site and installed it (I'm on a MacPro with High Sierra 10.13.1).

Installation went ok, however, when I launch the app, the splash screen appears, but after a few seconds it becomes unresponsive - hanging on the splash screen.

I've tried both the education and home versions of the app, but have the same problem with both.

Does anyone have any ideas/solutions?

Thanks

Upgrade to High Sierra 10.13.3 and try again.

Thanks for the reply, updated to 10.13.3 - but still having the same problem…

I had a similar issue the other day, I had to delete and reinstall microsoft silverlight. After that it worked.

Even on Mac we can't be Microsoft free (with the accompanying headaches).

I tried that, twice, but no luck :-(

Asked my son who is an IT engineer and this is his response :-

"Hard to say. I wonder if he has the brick connected when starting the app.
He could try disabling Bluetooth.
The forums talk about Silverlight issues.
Here’s a Lego guide to fixing it."

all the issues on Windows with EV3 software I've had - working in schools.. 95% of the time, it was silverlight.

even with it installed, and up-to-date.. it could fail to launch EV3.

to fix, I'd sometimes have to uninstall silverlight... clear out any silverlight leftover files (on disk, and in registry), and install a fresh, latest version.. and then it'd work

Not one of TLG's best decisions to use this particular programming system.... (at least it wasn't flash! ;)

Finally managed to get it working on a MacBook Pro instead.

There seems to be no obvious reason why it should work on one and not the other - I tend to agree that Silverlight is probably at the bottom of the problem.
