MacMini 2014 fan surge for 2 seconds and then 1 sort beep repeating over at boot
I have a an i7 16-GB 2014 Macmini, which has been a champion little machine and still is, but with increasing frequency when booting I hear the fan surge for a second followed by a short one beep. This repeats over until I restart the machine when it either disappears or starts again.
An SMC reset seems to fix it for a while until the next time. The fan was changed about a year ago. Temperatures are nominal using monitoring software like iStat menus.
Any ideas about the cause or should I be planning to buy the new Macmini Pro when it comes out soon (hopefully)?
