We can understand wanting to sync photos between your Mac and your iPhone. You can follow the steps on this page to help you with syncing your photos between devices: Sync photos between your Mac and iPhone or iPad - Apple Support

Sync photos to your device

1. Connect your device to your Mac.

You can connect your device using a USB or USB-C cable or using a Wi-Fi connection. See Sync content between your Mac and iPhone or iPad over Wi-Fi.

2. In the Finder  on your Mac, select the device in the Finder sidebar.

If you connect your device to your Mac using a USB cable and don’t see the device in the Finder sidebar, see If your device doesn’t appear in the sidebar. 

3. Click Photos in the button bar.

Note: When iCloud Photos is turned on, no photo syncing options appear when you click Photos in the button bar.

4. Select “Sync Photos to your device from” checkbox, then choose Photos, Pictures, or a folder from the pop-up menu.

5. Do one of the following:

- When syncing photos from the Photos app: Click “All photos and albums” or “Selected albums.” If you click the “Selected albums” button, select the checkboxes of the albums you want to sync in the Albums list. 

Click Photos or People to see your photos organized by that category.

- When syncing from the Photos app, select the “Only favorites” checkbox to sync only photos specified as favorites.

- When syncing from the Photos app, select the “Automatically include photos from” checkbox and choose a time period from the pop-up menu to sync only photos taken within that period.
