To update the access and modification times of files on a Mac, you can use Terminal command. This command allows you to modify the access and modification times of files. Here’s how you can do it:

Open the Terminal.
Use the touch command to update the file’s timestamp. For example, if you want to update the timestamp of the file example.txt, you can enter the following command. This will update the access and modification times of example.txt to the current time:
touch /path/to/your/file/example.txt
If you need to update the timestamps of multiple files at once, you can use a wildcard. For example, to update the timestamps of all .txt files in the current directory:
touch *.txt
