Keyboard commands on the Mac / Shortcuts Part 1 System start

A lot of helpful functions are integrated into your Mac, which can be easily activated via certain key commands, so-called shortcuts.

Today I present you some of them!

In general, the keyboard commands work on the MacBook / Pro / Air or on all Apple keyboards in connection with iMac / Pro, Mac Mini or Mac Pro.

But first the most important keys are briefly explained so that everyone knows what is meant:

Command (or cmd) key ⌘

Shift ⇧

Option (or Alt) ⌥

Control (or Ctrl) key ⌃

Caps Lock ⇪

Function key (Fn)

Keyboard shortcuts at startup (keys must be pressed and held at power-up):

ALT ⌥ - selection of the volume to boot

Shift ⇧ - Starts Mac OS X in safe mode

Command ⌘ + R - Starts recovery mode

D - Starts the system test (hardware diagnostics) only from BJ mid 2013

T - Starts in target disk mode (data can be transferred here
e.g. if a device no longer starts properly (Thunderbolt/Firewire))

Command key ⌘ + V - Verbose mode (here the boot process shows what is currently loaded)

Command ⌘ + ALT ⌥ + P + R - Performs a PRAM reset

Shift ⇧ + Control (CTRL) + ALT ⌥ - Performs an SMC reset
