I have an iMac G5 (May 2005) with OS X 10.11 that hasn't been used for over 1 1/2 years. I wanted to get the pertinent numbers and went to the system profiler (about this Mac). The window comes up but clicking on the more info button only gets the spinning wheel for several minutes and then some. What should I look for to fix it? I think I will try to make some use of this machine if *** is feasible.
