[Ham-Mac] Mac crashes on transmit or tune... any ideas?

[Richard Hemingway]

I had a G4 and had to TX in my retirement apartment with the antenna 
on a bookcase about 8-10 feet away.  Although I was only using 10 
watts (or less) with the G4 off but plugged in it went nuts!!  I sold 
it and bought a G5 with the aluminum case.  It is much better 
shielded and I have no problems with it, nor with the old Dell I used 
to have.  I think that it is the lack of shielding on the G4 that may 
be causing the problems.
