How do I sign out?

On Mac OS X, it logs out exactly as it does on other operating systems. Just know where the menu is hidden. Note that programs do not have a control menu in the same window as you might be used to from Microsoft Windows or KDE or Gnome, but it is separate and located in the bar at the top of the screen. In addition to classic items such as File , Edit or Help - the menu starts with the Apple logo, which is another menu item in which the searched "Log out" is located at the very bottom.

How to start a text terminal?

The text term can be started as follows:

  1. I open Finder (the first smiling face icon on the bottom bar).
  2. I click Applications .
  3. I will find Utilities .
  4. Click Terminal . For a moment, a jumping terminal icon may appear - meaning the application is launching.

A new terminal window is created by clicking File -> New Shell . The menu is at the top of the screen.

XCode Error "The operation couldn't be competed. (Cocoa error - 102.)"

You may encounter this error when trying to run your application via Xcode in iOS Simulator. It is caused by the fact that iOS Simulator does not support running applications that are in a network-connected location over NFS. In doing so, the home directories where the applications are located are currently mounted over NFS.

The solution is to create a local directory where the application will be stored and redirect iOS Simulator to it. You can do this by running the following commands in the terminal:

mkdir /tmp/$USER
mkdir -p ~/Library/Developer
rm -rf ~/Library/Developer/CoreSimulator
ln -s /tmp/$USER ~/Library/Developer/CoreSimulator

If you log on to another machine, you need a step with mkdir execute again because it is a local directory on the machine. It is a good idea to remove this directory after you finish rm -rf /tmp/$USER ).
