The Siri Remote was launched with the 4th Generation Apple TV in 2015. It uses both IR and Bluetooth to communicate with the Apple TV. The remote has a glass trackpad, dual microphones, 5 buttons for Menu, Home, Siri and Play/Pause, and a Volume up/down rocker button. An introduction to the Apple Menu for newcomers to the Mac.
If iTunes window is in full screen mode, moving cursor to the top of screen brings down menu bar. The menu bar can also be hidden in 'regular' (not full screen) mode, for all apps. To control if menu bar is hidden or shown, go to System Preferences General pane; there is a checkbox for Automatically hide and show menu bar. If that setting is NOT checked, the menu bar is always visible (for all apps) when the screen is not on full screen mode.
'Authorization' is for the computer (not iTunes library) to play content purchased using a particular Apple ID. One computer can be authorized to play content from multiple Apple IDs. One Apple ID can be authorized with up to 5 computers.
how do I authorise my Mac to accept my iTunes library which I am running on 2 x iPads, 1 x iPhone and a PC.
I'm not sure what you mean by this question. If you authorize the Mac for the Apple ID used on your other devices, and you sign in with that Apple ID in iTunes, you can download and play content purchased (with that Apple ID) on the other devices. But this is not directly related to the 'iTunes library' on the other devices. Apple ID and authorization is for purchased content from iTunes Store.
