Merge keywords

Helo marthalkj,

Thank you for using Apple Support Communities.

I understand that you would like to merge two keywords in Photos. I am not aware of a way to combine keywords, but you can create a new keyword made up of the two you want to merge and delete the individual words. Take a look at the following support article for using keywords in Photos:

Best regards.

Do you want to merge keywords like we could in Aperture? Photos has no tool to merge two keywords.

You have to do it manually. For example, if you made a typo and have two keywords "Dog" and "dog" and want to merge them to "Dog":

• Create a smart album (file > New Smart Album) with the two rules "keyword is dog" and "Keyword is Dog" and combine them with "Match any ....". This album will contain all photos with any of the two keywords.
• 
• Select all photos in the smart album with ⌘A and open the Info with ⌘i.
• In the info add the keyword you want to keep to the list of keywords, for example "Dog".
• Now open the Keyword Manager with ⌘K, click "Edit Keywords" and select the keyword "dog" and click the "-" button to delete this keyword from the Keyword Manager.

You will now have only the keyword "Dog", assigned to all photos.
