You can certainly do them one at a time. To help there is top of the Filters menu "Repeat.." option to speed things up a little.
The only recent 'configurable' batch plugin for Gimp is one called BIMP and AFAIK nobody has compiled one for a Mac since the old lisnenet OSX versions.
That leaves a dedicated plugin. I hunted all over for a script without luck (Google must be tired of the same question asked n-number ways) and had to pull out an old template python script to modify. That is attached, but very-hands-on. I am not good at scripting.
Select the folder with the photos, you can change the width but the border colour is white. Edit the script to change that

This works in linux, no guarantees that it works in a Mac. Unzip, put the file newborder.py in your user Gimp plug-ins folder. Check that it is executable. The menu entry is Tools -> newborder
A better bet is not Gimp. Use XnViewMP which has a batch process for selected images, including an add border filter. There is a Mac DMG here: https://newsgroup.xnview.com/viewtopic.php?f=82&t=40169
