You may get a one-time warning to be careful. You'll be prompted for your login password, which won't be displayed when you type it. exec chflags -h nouchg,nouappnd,noschg,nosappnd + 2>&.

If you have more than one user, and the one in question is not an administrator, then go to Step 2.Įnter the following command in the Terminal window in the same way as before (triple-click, copy, and paste): If none of this is meaningful to you, you don't need to worry about it, but you do need to follow the instructions below. Do so only after verifying that those settings didn't cause the problem. In that case, either stop here, or be prepared to recreate the settings if necessary.

If you've intentionally set special values for those attributes, they will be reverted. This procedure will unlock those files and reset their ownership, permissions, and access controls to the default. For information about modifying your zsh shell startup script to keep variables and other settings across multiple sessions, see the “Invocation” section of the zsh man page.Some of your user files (not system files) have incorrect permissions or are locked. If you want the value of a variable to persist across sessions and in all Terminal windows, you must set it in a shell startup script. Variables you set in one Terminal window aren’t set in other Terminal windows.Īfter you close a Terminal window, variables you set in that window are no longer available.

See your preferred shell’s man page.Īlthough child processes of a shell inherit the environment of that shell, shells are separate execution contexts that don’t share environment information with each other. For example, your app can check for the presence (or value) of an environment variable and change its behavior accordingly.ĭifferent shells support different semantics for exporting environment variables. This form of inheritance can be a useful way to configure the app dynamically. When you launch an app from a shell, the app inherits much of the shell’s environment, including exported environment variables.
