[iMac 'SNAP' and shut down on SL startup]

But it ONLY happens when Secondlife is started and as soon as it loads the splash screen. Cant even log in.. NO other app causes this problem.

Has anyone experienced issues with Secondlife and Sierra?

Right after upgrading to Sierra, my 1 gb graphics card went "kahblewy". I have an mid 2011 27" 3.4 GHz Intel Core i7 iMac with 24 gb ram. I just assumed the card went bas so I decided to replace the broken 1 gig card with a new 2 gig graphics card. Unfortunately, now every time I open Secondlife I hear a 'SNAP' and my iMac shuts down.

NO other program so far has caused this issue and I'm starting to wonder if Secondlife/Sierra compatibility issues weren't to blame all along?

I'm so frustrated!

Any input would be appreciated!
