installation report
I have two Mac computers. On both I found that Sage 6.5 won't work with OS 10.9. So, I installed OS 10.2 on both Macs, deleted the old Sage.app 6.5 for OS 10.9, and installed the new Sage.app for OS 10.10. One one Mac, everything worked. On the other Mac, I had difficulties. Repeatedly I found that I couldn't start a terminal session and found in the log, "another Sage Notebook server is running". I discovered that by choosing Stop Server from the Server menu a couple of times I could cure this problem and start a terminal session. This happened even after a restart. Well, now I know what to do so it isn't blocking any work, but I thought I would report it. Possibly I double-clicked the Sage icon in the dock? Would that start two servers? Why, anyway, would having two Notebook Servers running interfere with a terminal session? This is supposed to be a "question" so that last sentence is the official "question" here.
