From today’s mail bag:
I installed the APC software on the Mac side, but when I try to open it there, I get a notification that the APC preference pane will not work on an Intel-based Mac. However, during a recent outage when a sprinkler repairmen suddenly shut off our power, the battery backup worked. Its software was obviously installed on the Mac side, but I don’t remember whether it was also installed on the Windows side. Do I need to install it on the Windows side or do I need a new backup system?
