#Mac usb mouse not working Bluetooth
If any inputs are being sent via the Bluetooth keyboard before the controllers are active, then they will not be recognized by the system. These are then passed to the OS X kernel to invoke the desired startup sequence. It is at this point that the system will accept boot variables, either stored in the PRAM or those being sent via keyboard inputs. There are a couple of workarounds if you find yourself in this situation.Īpple's Bluetooth hardware controllers activate after all of the system's self-tests at boot complete and the EFI firmware loads successfully, which is indicated by the system playing the standard Mac startup sound. While you might assume that these options require a USB keyboard or other physical connection, this is not always the case. If you use Apple's Bluetooth keyboard, you could find that the system may ignore these inputs and boot normally. I found this info so thought I'd post it just in case another new Mac user would find it useful! I haven't posted nor saved any of the exact info from console I haven't attempted due to the problem above for one and would like to resolve the bluetooth driven mouse problem for now.
#Mac usb mouse not working how to
T've been thinking about doing a clean install How to make a bootable OS X 10.11 El Capitan installer drive using the built in createinstallmedia in terminal. So, when I couldn't find the solution to mouse not working I thought I'd post. One suggestion was to run disk utility first aid in recovery so gave it a try only to find I couldn't run first aid not being able to select it in recovery using keyboard only. I use various search engines to do a bit of reading researching on the errors. I've been looking at console logs and researching some of the failed messages such as address book, mail, spotlight, calendar, boot problems updating accounts etc. My usb keyboard works in recovery but the bluetooth driven mouse does not work at all. I am using a usb Apple keyboard and a bluetooth driven magic mouse 2.
