My dad has a late 2009 iMac which he recently installed El Capitan, 10.11, on (perhaps the age of the Mac paired with the new iOS is the issue - I am unfamiliar with Macintosh). Upon bootup, the Bluetooth mouse and wireless (which are all that he currently has) take FOREVER to detect. Does anyone know of any settings to alter, or troubleshooting tips to try to speed up the connection? It used to be near instantaneous. Apps are also slow to open, but that is not as annoying as not being able to use the mouse and keyboard without waiting 5-10 minutes after boot.
Any help is greatly appreciated!
