1. Why Do I Have so Many Duplicate Photos on My Mac?

We use iPhoto on Mac to store our precious pictures. As a photo library, it may have stored thousand of photos from multiple sources. Such as you imported them from mobile phones or downloaded them from the internet. So, duplicate photos are a common problem on Macs. Typically duplicate photos accumulated due to a couple of reasons. 

1.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.

2.The other reason 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.

2. Can Mac Find Duplicates in Photos?

To be honest, the iPhoto on Mac cannot detect duplicates automatically, and only by checking the duplicates manually can we delete those photos. It's worth mentioning that sometimes these duplicate files are visible while other times they are hidden. No matter how these photos wind up on your computer, they're eating up valuable disk space, potentially slowing down your computer, and you will need to remove them.

3. How Do I Get Rid of Duplicate Photos on My Mac?

There are two ways to remove duplicate photos on Mac. One way is to delete photos manually, another is a more straightforward method which could save you a great amount of time. Let's take a look at each of these in more detail.

Step 5. Review each photo manually (If you have 10,000 photos, this will cost an exceptionally long time).

Step 6. Delete when you find a duplicate.

If you have a minimal number of photos, the steps above might work. However, if you have thousands of pictures on your computer just like normal people do, this method can be extremely time-consuming. Also, if you delete the original photo incorrectly and empty the trash, you will find that it is impossible to reverse that. Therefore, it's not the best way to go about it.
