Locking files and folders is one of the practical ways to prevent unwanted edits in personal and sensitive information, and in some cases, it can prevent data deletion and future problems. But How to lock a folder on Mac?
Two tools, Finder and Terminal, are used to lock files and folders in MacOS and can prevent data from being deleted. By doing this, the possibility of unintentionally changing or deleting files is eliminated. Also, if you share a user account with others, it might make sense to put a lock on the folders.
Locking editable files and documents makes it possible to open and read their contents, but the operating system will prevent changes to the file. Also, putting a lock on a folder will include all its contents and keep files away from unwanted editing. If the user tries to delete a locked file, MacOS will display an error message to confirm the process.
How to lock a folder on Mac With Finder
The easiest and fastest way to lock files and folders on MacOS is to use the Finder tool. To start, first, click on the item you want to control and then select the “Get Info” option and tick the “Locked” option.
Now the selected item will be locked and there will be no need to go through any additional steps. To return to the previous state, just uncheck the Locked option in the Get Info window. Locked files and folders will always have a small icon next to them, making them easier to identify.
How to lock files on Mac with the terminal
Using the terminal is a more complicated way to lock various things in MacOS, which is not very popular with normal users. First, you should check the current status (locked or not) of the desired item with the terminal; As a result, open the terminal tool and then enter the following code in it. Note that instead of [File path], replace the address of the desired file. Next, press the “Return” key.
ls -lO [file path]
“uchg” indicator allows you to check the status of the lock on a specific item. If this statement is seen in the output of the said command, it can be concluded that the selected item was locked, and otherwise, it can be ensured that it is not locked.
Now you can use the following command to lock the unlocked items. Just replace [File path] with your desired file address and hit the “Return” key.
chflags uchg [file path]
There will be no difference in the end result between using the Finder or the Terminal to lock files and folders, and ultimately provide the same functionality. To unlock an item through the terminal, the following command can be used.
chflags nouchg [file path]
Note that using a file lock in MacOS cannot prevent unauthorized access to user information, and other encryption methods are available for this purpose. A locked file can be easily edited and deleted only by unlocking it. If you’re looking for additional layers of security on your data, you can use the encryption options and apps available for MacOS.
