How to delete multiple photos on Mac Photos
The Mac Photos app provides a convenient way to manage and organize your photo collection. However, if you have multiple photos you want to delete, the process is straightforward. Here’s a step-by-step guide on how to delete multiple photos on Mac Photos.
1. Open the Photos app: To begin, launch the Photos app on your Mac. You can do this by clicking on the Photos icon in your dock or by searching for it in Spotlight.
2. Select the photos you want to delete: Once the Photos app is open, navigate to the album or event where the photos you want to delete are stored. To select multiple photos, click on the first photo, then hold down the Command (⌘) key and click on each additional photo you want to delete. Alternatively, you can click and drag to select a range of photos.
3. Delete the selected photos: With the photos selected, click on the “Delete” button located in the upper-right corner of the Photos app. This button is represented by a trash can icon. Confirm the deletion when prompted.
4. Empty the trash: After confirming the deletion, the selected photos will be moved to the trash. To permanently delete the photos, you need to empty the trash. Click on the trash can icon in the dock, then select “Empty Trash” from the menu that appears.
5. Confirm the permanent deletion: A confirmation dialog will appear asking if you are sure you want to permanently delete the photos. Click “Empty” to confirm and delete the photos from your Mac.
That’s it! You have successfully deleted multiple photos on your Mac using the Photos app. Remember that this process will permanently delete the photos, so make sure you have a backup if needed.
