HOW TO RESTART A MAC FROM KEYBOARD SOFTWAREĪfaik there is no specific reset procedure for the wireless keyboard, as the modifiers all reside in the system software of the affected iMac.Apple offers several alternative boot environments for OS X that can help you troubleshoot problems you might be experiencing, which can be invoked by holding various key combinations at startup. Of these, Safe Mode is perhaps the most common it offers a limited boot environment and can be started by holding the Shift key. In addition there is Single User mode (Command-S) for a command-line interface, Apple's hardware diagnostics tests (the "D" key), Target Disk mode (the "T" key), and holding the Option key will bring up the boot loader for choosing a startup disk. These options can be invoked by holding their respective key combinations immediately when powering on the system however, if you use Apple's Bluetooth keyboard, you could find that the system may ignore these inputs and boot normally. While you might assume that these options require a USB keyboard or other physical connection, this is not always the case. 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.
It is at this point that the system will accept boot variables, either stored in the PRAM or those being sent via keyboard inputs. These are then passed to the OS X kernel to invoke the desired startup sequence. If any inputs are being sent via the Bluetooth keyboard before the controllers are active, then they will not be recognized by the system. HOW TO RESTART A MAC FROM KEYBOARD BLUETOOTH
