Bluetooth keyboard/iMac connection too slow
I turned off Bluetooth this morning for reasons I can't remember. Unfortunately, I couldn't make the connection again, so I couldn't use my wireless keyboard with my iMac. I called Apple for help. They couldn't help, so we both decided that I would have to take my computer in for repairs. Later, I started using my iPad, and it occurred to me to check on the Bluetooth connection by trying to use my wireless keyboard with it. It worked. I then tried again to use the wireless keyboard with my iMac, and it worked.
I don't think you can consider this normal. What are some reasons for the long delay in getting my wireless keyboard to connect with my iMac? Incidentally, to avoid this kind of problem in the future, I just ordered a cheap wired keyboard from Amazon. That will be my failsafe, but I'd still like to know why I would have this problem.
