How to Change The Default Application In macOS
In macOS each file type is opened automatically by a default application. This short blog post will explain how you can change the default application a file opens with.
Is your Mac refusing to shut down? Most likely an application or background process has frozen, preventing the process to close and in turn preventing macOS to shut down. This hack will show you how to use terminal to force a shut down.
Force Shut Down In Terminal
Open Terminal: Finder > Applications > Utilities
In Terminal, type or paste the following…
shutdown -r now
(return)
Force Shut Down (sudo) In Terminal
If the above command fails to initiate the Mac’s shut down process, place the word sudo (super user do) in front to switch to administrative root access.
Open Terminal: Finder > Applications > Utilities
In Terminal, type or paste the following…
sudo shutdown -r now
(return) (enter Mac password) (return)
::TIP:: if you know which application is causing the issue then: click on > Force Quit… (on the top menu bar), select the offending application and click on the Force Quit button. Once the application has closed you should then be able to shut down.
