Automatic Import of Photos

The only thing I can say is that when I insert a SD card the Photos app does NOT automatically start to import. I’m given the option to import all photos on the card or just recent ones. From the link provided by Crucader188

Import from a card reader or SD card

1. Insert the card into your computer’s SD card slot, or connect a card reader to your computer and insert the card into the card reader.
2. In Photos, choose File > Import, then select the photos or videos you want and click Review for Import.
3. Note: If you participate in an iCloud Shared Photo Library, click the Library pop-up menu in the toolbar and choose the library to import into.
4. If you selected multiple photos or videos, do one of the following:

• • Import all new photos: Click Import All New Photos.
  • Import a selection of photos: Click the photos you want to import, then click Import Selected.

1. If a message asks whether you want to delete or keep the photos on your card after importing them, click Delete Items or Keep Items.
2. To cancel importing, click Stop Import.
3. When all photos have been imported, eject the card from your computer or card reader.

Imported photos appear in the Imports and Library albums in the sidebar.

It certainly seems to indicate you can select what photos you want to import.

And here’s a link about disabling automatic importing.

Hi,

I would suggest trying to do this:Import photos from storage devices and DVDs using Photos on Mac - Apple Support

Let me know if that helps!
