GeoTag for macOS -- macOS 13 or later
GeoTag is a free OS X single window application that allows you to update image metadata with geolocation tags by selecting one or more images then panning and zooming within a a map to the place the image was recorded. Clicking on the map will add the location to the selected photos. Clicking on a new location will change the geolocation for the selected photos. Zoom in on the map and fine tune the location with a click. The built in ExifTool utility is used to write location data to the images when you save your changes. ExifTool only modifies image metadata -- your image pixels are not touched.
See http://exiftool.org for information about ExifTool. ExifTool is built in to GeoTag.
GeoTag Version 5 is a re-write of the program taking advantage of features in the current version of macOS. Those not using macOS Ventura can use GeoTag version 4.15.
Version 5.1 (not yet released)
Updates
- Add option to always create sidecar (XMP) files when updating images.
- Update both images of a raw/jpeg pair when the location of one of the paired images changes. This only applies if both images of the pair were opened and enabled or if updates are written to a sidecar file.
- Add "Report a bug..." to the help menu. Selecting this will open the GeoTag github issues page in your browser.
- ExifTool version 12.62
Bug Fixes
- Performance improvement when opening large number of images.
- Do not clear window changed indicator when there are save errors.
- GPS Timestamp written to sidecar files sometimes included a timezone instead of being a UTC/GMT relative timestamp.
- Crash that could occur when opening the Setting window.
- Sidecar file backups would sometimes fail.
- image thumbnail could fail to show until the selection changed.
Known bugs
- performance is still an issue. When opening 1200 images, for example, it takes 15-20 seconds on a 3.6 GHz 8-Core Intel Core i9. When selecting an image from the table it takes 2-3 seconds before the selected image is rendered. The performance issue is related to number of images. The selection delay is barely noticeable when 120 images are open.

General Note
Photos (OSX 10.10.3 and later) will let you modify existing location metadata but not add location data to an image. Use GeoTag to add location metadata before importing the images into Photos. This may also hold true for other image editing applications.
Operating Instructions:
See https://www.snafu.org/GeoTag/GeoTag5Help/ for more information.
Run Program. Use the Open command from the menu or ⌘O to select files to modify. You can also drag files from the finder into the table on the left side of the application window. File names shown in a light grey color are not recognized as valid image files or are disabled for other reasons. Such files can not be modified. Dragging or opening a folder will add all the files in the folder and any subfolders.
Select one or more images. When selecting multiple images one of the images is considered the "most selected". The name of the most selected image is shown in yellow using a bolder font. The thumbnail of the most selected image is displayed in the image well (upper right portion of the window). Its location (if any) is marked on the map.
Click on the map to set or change the location of all selected images. Existing location can be changed by clicking on the desired location. Hitting the delete key will remove location information from all selected images. You can Undo/Redo image location changes.
Double click the map to zoom in. Or use the pinch gestures to zoom in and out.
Three map types --- Standard, Hybrid, and Satellite --- are supported. You can also use street view, but... the latitude and longitude of a map marker in street view do not match the same marker on one of the other three map views.
If you find yourself working in a specific area of a map you can save the map type, location, and zoom level by clicking on the Save map location button. When GeoTag is launched the map will load to the last saved location.
You may cut or copy location information from a single image and then paste that information into one or more images. If you make an error you can undo/redo your changes. You can undo all changes to all images by selecting "Discard changes" from the "File" menu. All Undo/Redo information is cleared once changes are discarded or saved.
The original versions of images that have been updated are saved are in a backup folder. The backup folder may be changed using GeoTag Preferences. The first time GeoTag is run it will prompt you to select a backup folder. Images updates can not be saved until a backup folder is selected or backups are disabled (not recommended).
Cut, Copy, Paste, Delete, and Clear Image List can be accessed from a pop up menu by right clicking on an entry in the list.
