To export only photos you have not handled before, keep a clear record of the last completed batch in Photos, select the next items, and export them to a separate dated folder. Photos provides export options for format, filenames, and folders, but its documented controls do not include an export-history list or a “skip items already exported” switch. A repeatable album-and-folder routine is the practical way to track your own progress.

Set up a simple export checkpoint

In Photos on your Mac, create an album for the next batch, such as “To export — October 2026.” An album is useful as a checkpoint: it groups the exact items you intend to process, and an item can belong to more than one album. Select the photos or videos and choose File > New Album with Selection, or add the selection to an existing album. Apple’s album guide documents these controls.

After exporting and checking the destination, keep the batch album as your record or add those items to a separate album named “Exported.” Use a date in the album name so you can tell which batches are complete. This is a manual record: Photos albums organize library items; they do not prove that a corresponding file still exists in the export folder or that a transfer finished successfully.

If you already have a large export archive and no record of which library items it contains, avoid selecting everything and relying on filenames to spot repeats. First compare a manageable group against the destination and establish a checkpoint for confirmed exports. If the destination was renamed, reorganized, or partly deleted, album membership alone cannot confirm its current contents.

Find new items without confusing capture date and export status

For a recurring workflow, choose a clear cutoff—such as the last day you completed an export—and inspect items taken after it. Photos’ Library > All Photos view is chronological by date, and its Recent Days collection groups items by the day they were taken. These views help find recent captures, but capture date is not the same as the date a file was added to your library or exported. Older scans, shared images, and late imports may need separate review. Apple’s date-browsing instructions describe the date-based views.

You can also make a Smart Album to gather items matching criteria, such as a date condition. Smart Albums update to match their criteria; they are not an export log. Apple describes date as a criterion for finding items, but does not document a Smart Album rule that marks an item as exported. Use a Smart Album to narrow a review only when its conditions fit your workflow, then compare its results with your completed batch record. Apple’s Smart Albums guide explains how to create and edit one.

Export the selected batch to a distinct folder

Select only the items in your new batch album. For a regular export, choose File > Export > Export [number] Photos. Pick the appropriate format and size, then choose a filename option and subfolder format if useful. Apple documents naming files by their Photos titles, original filenames, or a sequential pattern. Export into a new destination folder with a date in its name—for example, Photo Exports/2026-10-15—so the batch remains separate from earlier files. Apple’s export instructions cover these settings.

If you need the files as imported, choose File > Export > Export Unmodified Original. Apple notes that a Live Photo exports as two files: one still image and one video. For this option, Photos can also export assigned IPTC information and keywords as an XMP sidecar when you select Export IPTC as XMP. The extra file for a Live Photo is expected, so do not mistake it for a duplicate export.

Avoid sequential filenames as your only duplicate-prevention method. They label a batch, but do not establish whether a particular photo appeared in a previous batch. Likewise, the same source photo can have different exported filenames or formats. A separate dated folder plus a maintained batch album gives you two useful clues—where a batch went and which Photos items you selected—without treating a matching filename as definitive proof.

Verify the batch before marking it complete

When Photos finishes exporting, open the dated destination folder in Finder and check that it contains the expected files. For a small selection, compare the visible items with the selection; for a Live Photo exported as an original, account for its still and video files. If anything is missing or the export was interrupted, leave the batch marked as pending and resolve it before treating it as complete.

On the next run, select only items beyond your chosen cutoff that are not already in your completed album. Then create a fresh batch album and destination folder. This process reduces accidental repeats while keeping the decision visible and reversible. It does not automatically detect duplicates across unrelated folders, identify renamed copies, or restore files that have been removed from the destination; those cases require a separate manual comparison.
