Hi, guys, I'm using LTspice IV in mac book. I want to use OPAM TS912 during circuit simulation. For that I copied the file TS912.asy  in sys. and ts912.txt in lib. but during simulation I couldn't find that OPAM. How to solve this problem? Plz guid me. And also another problem I encountered that I couldn't update the software. It's showing 577 days is left to update from my first installation.
