In the case of executable files, the icon will have a security shield overlay. The following tasks require administrator privileges: [9] [10] Running an Application as an Administrator; Changes to system-wide settings; Changes to files in folders that standard users don't have permissions for (such as %SystemRoot% or %ProgramFiles% in most cases)
An attacker can manipulate those files and through them exploit a vulnerability in the signed application. The application and its external files can then be redistributed, while leaving the original signature of the application bundle itself intact. As Gatekeeper does not verify such individual files, the security can be compromised. [15]
When the other task is blocked, it is unable to execute until the first task has finished using the shared resource. Programming languages and scheduling algorithms are designed to minimize the over-all effect of blocking. A process that blocks may prevent local work-tasks from progressing. In this case "blocking" often is seen as not wanted. [2]
Sometimes the old "turn it off and on again" actually works. In this case, try completely signing out of your account then sign back in. Many times, this will help, especially in cases of bad passwords or some simple browser issues.
If your third-party email app is having issues connecting, sending, or receiving emails, you may need to reconfigure your account or update the app. Use these steps to identify and fix the source of the problem.
Verified for iOS 9.3 and later. 1. Double press the Home button or swipe up and hold. 2. Swipe up on the image of the app. 3. Re-launch the app and attempt to reproduce the issue.
RUNNING → BLOCKED: A process is put into the BLOCKED state if it requests something for which it must wait. A request to the OS is usually in the form of a system call, (i.e. a call from the running process to a function that is part of the OS code).
Most file systems include attributes of files and directories that control the ability of users to read, change, navigate, and execute the contents of the file system. In some cases, menu options or functions may be made visible or hidden depending on a user's permission level; this kind of user interface is referred to as permission-driven.
