bluetooth drops out on imac
Several times a day bluetooth drops out on imac disconnecting keyboard or mouse. Most times turning off then on keyboard or mouse resets system. Sometimes computer needs a restart. changing keyboard and mouse has no effect. We have 2 iMacs (late 2017). Both have the problem but it worse on one of them.
How can I fix this?
iMac 21.5″ 4K, macOS 12.0
