Mojave MacOS : I understand that you are experiencing Finder warnings when attempting to delete a file on your Mac running the Mojave operating system. These warnings can be frustrating and disruptive, but there are several ways you can prevent them from appearing. In this article, I will discuss the causes of these warnings and provide some solutions to help you avoid them.
What causes Finder warnings when deleting files in Mojave?
Before we dive into the solutions, it is important to understand why Finder warnings appear when deleting files in Mojave. The most common reason is that the file you are attempting to delete is currently in use by another application or process. When this happens, Mojave will prevent the file from being deleted and display a warning message to alert you to the issue.
Another possible cause of Finder warnings when deleting files is insufficient user permissions. If you do not have the necessary permissions to delete a file, Mojave will prevent the deletion and display a warning message.
Finally, some files may be protected by Mojave’s system integrity protection (SIP) feature. This feature is designed to prevent users from modifying system files or directories that are essential to the operating system’s functionality. If you attempt to delete a file that is protected by SIP, Mojave will display a warning message.
Now that we have identified the causes of Finder warnings when deleting files in Mojave, let’s explore some solutions to help you avoid them.
Close applications using the file
As mentioned earlier, one of the most common causes of Finder warnings when deleting files in Mojave is that the file is currently in use by another application or process. To avoid this issue, you should ensure that all applications that might be using the file are closed before attempting to delete it.
To check if an application is using a file, you can use the “Activity Monitor” utility that is built into Mojave. Here’s how:
Open “Activity Monitor” from the “Utilities” folder in the “Applications” folder.
In the “Activity Monitor” window, click on the “CPU” tab to sort the processes by CPU usage.
Look for any processes that are using a significant amount of CPU and may be related to the file you are trying to delete.
If you find a relevant process, select it and click the “Quit Process” button in the upper left-hand corner of the window.
After closing all relevant applications, try deleting the file again and see if the warning message still appears.
Check and modify user permissions
If the file you are attempting to delete has restrictive user permissions, you may need to modify these permissions to enable deletion. Here’s how:
Right-click on the file you want to delete and select “Get Info” from the contextual menu.
In the “Get Info” window, click on the “Sharing & Permissions” section.
Check the permissions listed for your user account. If your user account does not have “Read & Write” permissions, click on the lock icon in the bottom right-hand corner of the window to unlock the section.
Enter your administrator username and password when prompted.
Click on the “+” button to add your user account to the list of users and groups with permissions.
Select your user account from the list and set the permissions to “Read & Write”.
Click on the gear icon at the bottom of the window and select “Apply to enclosed items” from the contextual menu.
Click on the “OK” button to save the changes.
After modifying the user permissions, try deleting the file again and see if the warning message still appears.
