2. The Manual Way to Delete Photos on Mac - May Cost Many Hours

Time needed: At least 1-2 hours. It depends on how many photos you have.

Operation Difficulty: Very high.

Of course, it is possible to remove these files manually. You can always load up the Pictures folder and set the icon size to include the preview. You can then scan through each photo, looking for duplicates. If you have a minimal number of photos, this method might work. However, if you're like most people and have thousands or tens of thousands of pictures on your computer, this method is effectively so time-consuming.That it is impossible! Also, if you delete the original photo incorrectly and empty the trash, you will find that it is impossible to reverse that.

Manually delete duplicate files is tedious, time-consuming, and error-prone. You can follow these steps to do it:

  1. Open Finder.
  2. Go to the File menu and then choose "New Smart Folder."
  3. new smart folder on mac

  4. Click on the "+" button in the top-right corner.
  5. Select Search parameters: Kind, Date, Name, File type and others. You're looking for all files that have an image file type.
  6. select Search parameters

  7. Review each photo manually (if you have 10,000 photos, this will be an exceptionally long time!).
  8. Delete when you find a duplicate.

Some people recommend opening Finder and sorting by name so that you can see duplicate file names. Usually, these tips don't apply to photos because they are all in one folder and cannot have duplicate file names anyways (you can't have two files with the same name in the same folder).

As such, while scanning your photos one-by-one to eliminate duplicate photos on Mac is technically possible, it's not the best way to go about it. Using software like Umate Mac Cleaner is faster and safer.

3. How To Stop Photos From Creating Duplicate Files In Mac OS X

After you clean your computer with Umate Mac Cleaner, you will likely want to stop Photos from creating these duplicate files in the future. Of course, you can always rerun the software, but prevention is often the best. That will ensure you never have duplicate photos eating up hard disk space.

Typically duplicate photos accumulated due to a couple of reasons. The main one is that you have an automatic import happening (iCloud Photo Library, for example), and then you trigger a manual import. Just because the iPhoto on Mac cannot detect and identify the duplicated pictures, so the multiple ways to import photos can be the major reason for duplicated files accumulation on Mac. Usually, you can prevent this problem by sticking to one importing method.

The other way that duplicates can happen is through bugs in the Photos app. Unfortunately, no software is perfect, and the iPhoto app is notorious for getting confused and having issues. Sometimes these issues result in extra pictures going into your library. The photo library is also an application that takes up a larger percentage of Mac's total space because of the large amount of storage and a large amount of space taken up per photo or video. This makes it especially necessary to regularly clean up duplicate files on Mac iPhoto.
