Editing photos on a Mac is simple using the built-in Photos app for non-destructive adjustments or Preview for quick file edits; third-party software like Adobe Lightroom or Luminar Neo adds professional capabilities.
Whether you need to crop a screenshot, remove a distraction from a vacation shot, or edit RAW files from a professional camera, your Mac can handle it. The trick is knowing which tool fits the job. The built-in Photos and Preview apps are free and already on your machine. For heavy lifting, options from Adobe to Affinity Photo bring AI-powered tools and layer-based workflows. Here is how to edit photos on a Mac, starting with the apps you already own.
The Two Built-In Photo Editors on Your Mac
Every Mac ships with two image editors, each designed for a different workflow. The Photos app is non-destructive — it keeps your original file untouched and stores edits separately. Preview edits the file directly, so saving overwrites the original.
Editing With the Photos App (Non-Destructive)
The Photos app is your starting point for most edits. It supports RAW files from major camera brands, lets you apply Curves and Levels for tone control, and includes a Retouch brush for removing spots or sensor dust.
- Open the Photos app and double-click a photo to view it.
- Click Edit in the top-right toolbar, or press Return.
- Use the toolbar controls:
- Crop / Straighten — drag the grid handles or rotate the angle slider.
- Adjust — tweak exposure, brilliance, highlights, shadows, saturation, and white balance. The “Auto Enhance” wand icon in this section balances the shot in one click.
- Filters — apply photographic style presets.
- Retouch — brush over blemishes or unwanted objects; the tool samples the surrounding area.
- Curves / Levels — fine-tune tonal range and color channels for precise control.
- Red-Eye — automatically corrects flash-induced red pupils.
- Click Done or press Return to save the edits.
the edited version appears in your library, and the original stays hidden in the background. To revert completely, go to Image > Revert to Original or click the reset button in the Edit toolbar.
Quick File Edits With Preview (Destructive)
Preview is best for one-off image changes — cropping a screenshot, adding an arrow, or erasing a background with its Instant Alpha tool. Because edits overwrite the file, use File > Export to keep a copy of the original.
- Open the image in Preview (double-click or drag it onto the app icon).
- Click the Markup toolbar icon (pencil tip near the top-right) to reveal the editing bar.
- Select a tool:
- Crop — drag the corner handles and press Return.
- Instant Alpha — click and drag over the background to select it, then press Delete to remove.
- Shapes / Text — add rectangles, circles, speech bubbles, or text boxes.
- Adjust Color — go to Tools > Adjust Color for exposure, contrast, and tint sliders.
- Choose File > Export to save a new copy while keeping the original intact.
What Each Built-in Tool Does Best
The table below shows which edits each app handles well and where they fall short.
| Feature | Photos App | Preview |
|---|---|---|
| Crop & Rotate | Yes, with straighten slider | Yes, quick crop tool |
| Exposure & Color | Full adjustment panel with Curves/Levels | Basic sliders via Adjust Color |
| Retouching (spot removal) | Yes, Retouch brush tool | No |
| Background Removal | No dedicated tool | Yes, Instant Alpha |
| Non-Destructive Edits | Yes — originals preserved | No — Save overwrites the file |
| RAW File Support | Yes (Canon, Nikon, Sony, and many others) | No — JPEG, PNG, TIFF only |
| Layer or Mask Support | No | No |
Best Third-Party Photo Editing Software for Mac (2026)
When built-in tools aren’t enough — for layer-based compositing, AI masking, or advanced color grading — these apps are the top choices for Mac users. Adobe Photoshop is the industry standard, and many editors pair it with Lightroom for catalog management and non-destructive RAW processing.
| Software | Best For | Pricing |
|---|---|---|
| Adobe Photoshop | Full layer-based editing, compositing, AI tools | $10/month (with Lightroom) |
| Adobe Lightroom | RAW photo management, non-destructive edits, cataloging | $10/month |
| Luminar Neo | AI-powered one-click enhancements, sky replacement | One-time purchase or subscription |
| Affinity Photo | Affordable layer editing, no subscription | Free (previously paid) |
| Photomator | Apple-native design, machine learning tools | Free with paid upgrades |
| RawTherapee | Open-source RAW processor for detailed control | Free |
Which Macs and macOS Versions Support These Features?
The built-in Photos and Preview apps are available on all Macs running macOS 10.15 (Catalina) or later. Some of the more powerful editing tools — like the Retouch brush and Vibrance slider in Photos — require macOS Big Sur (11.0) or newer. Most AI-driven third-party apps run best on Macs with Apple Silicon (M1, M2, M3 or later). On older Intel-based Macs, tasks like AI object removal in Luminar Neo or Photomator can be noticeably slower. iCloud sync works across all devices when enabled in Photos preferences, but RAW edits made in third-party apps won’t sync through Apple’s ecosystem — those files need to be exported and transferred manually.
Three Common Editing Mistakes to Avoid
Even experienced Mac users hit these traps. Saving over the original in Preview is the most common — a quick Save rather than Export wipes the unedited version. The fix: always use File > Export in Preview, or work in Photos where the original is locked away. Another frequent error is editing JPEGs when a RAW file exists. Photos sometimes defaults to the JPEG unless you right-click and choose Edit Original. Finally, many skip the Auto Enhance wand in Photos, which handles basic balancing faster than manual slider tweaking.
Quick Decision Guide: Choosing Your Photo Editor
Your choice of editing tool depends on what kind of photos you work with and how much control you need. For casual edits and family photos, the built-in Photos app is all most Mac users need. If you shoot in RAW or need layers and masks, move to Lightroom or Affinity Photo. Professional compositing and heavy retouching demand Photoshop or Luminar Neo.
- Quick crop or background removal on one image → Preview
- Library management plus basic exposure and color tweaks → Photos
- RAW editing and bulk cataloging → Lightroom
- Layer-based design and composite work → Photoshop or Affinity Photo
- AI-powered one-click edits → Luminar Neo or Photomator
