Subject: [PATCH] atime may not updated unless strictatime is set on macOS
 Catalina

Cited from mount(8):

```
strictatime
        Always update the file access time when reading from a
        file. Without this option the filesystem may default to a
        less strict update mode, where some access time updates
        are skipped for performance reasons. This option could be
        ignored if it is not supported by the filesystem.
```
