Hi NitroOxide,
It sounds like you're having an issue exporting photos. For help with exporting, test the steps below found in the article here: Export photos, videos, slideshows, and memories in Photos on Mac
"You can export photos in the original file format in which they were imported into your Photos library. A Live Photo is exported as two separate files: a still-image file and a video file.
- In the Photos app
on your Mac, select the photos you want to export. - Choose File > Export > Export Unmodified Original.
- If you want to export IPTC information (assigned IPTC metadata and keywords) as a sidecar XMP file, select the Export IPTC as XMP checkbox.
3. Click the File Name pop-up menu and choose how to name the exported files (this step is optional).
You can name your exported files using the titles you’ve given them in Photos, their filenames, or a filename numbered sequentially. If you choose Sequential, you can specify text to appear before each number (for example, Birthday - 1, Birthday - 2, and so on).
4. Click the Subfolder Format pop-up menu and choose how to divide the exported files into folders.
For example, if you export photos from several different days, you can have Photos export each day as a subfolder named after the day. Choose None to export the photos as individual files without subfolders.
6. Click Export.
7. Choose where to save the exported photo files, then click Export Originals."
