My iMac doesn’t recognize my wireless keyboard. I replaced batteries, restarted several times. The green light comes on for a few minutes then flashes then goes out.
What can I do to log on my iMac? It does recognize my wireless keyboard. I replaced batteries with brand new ones. The green green light comes on for a few seconds, then flashes, then goes out. I’ve restarted several times. Help!
iMac 21.5″, macOS 10.12
