How to hide photos in Finder
The simplest solution is not to allow other people to access your user account. If other people, (work colleagues, family members, friends, etc,) need to use your computer, create separate user accounts for them, or utilize the Guest account. If you have enabled System Preferences &gt; Users &amp; Groups &gt; Login Options &gt; Automatic login to login to your user account on startup, disable it now and use your Username or User icon and your password to login. Giving access to your user account to anybody who uses your computer is not a "best practice" and leaves your computer open to malicious or unintentional damage, as well as diminishing your privacy.
