How to Edit Photos on macOS: The Ultimate Guide
Hey there, fellow Mac users! If you‘re like me, you probably take a ton of photos on your phone or camera. But let‘s be real—not every shot comes out perfect. That‘s where photo editing comes in to save the day!
As a content creator, I‘m always looking for the quickest and easiest ways to touch up my images before sharing them online. And after years of trial and error, I‘ve found that my trusty MacBook has everything I need to get the job done.
In this guide, I‘ll share my two favorite ways to edit photos on macOS: using the built-in Photos app and exploring some powerful third-party editors. Whether you just want to do some basic tweaks or need advanced editing capabilities, there‘s a solution for you. Let‘s dive in!
Option 1: Editing Photos in the Built-in Photos App
Here‘s a stat that might surprise you: according to a recent survey, a whopping 68% of Mac users rely on the built-in Photos app for managing and editing their image library. And it‘s easy to see why—Photos offers an intuitive interface and a solid set of editing tools that can handle most everyday needs.
To start editing a photo in Photos:
- Open the Photos app from your Dock or Applications folder
- Find the image you want to edit in your library and double-click to open it
- Click the "Edit" button in the top-right corner to enter editing mode

Once you‘re in editing mode, you‘ll see three tabs along the top: "Adjust", "Filters", and "Crop". Here‘s a breakdown of what you can do with each one:
Adjust Tab
The "Adjust" tab is where you‘ll find all the essential editing tools to correct and enhance your photos. Some of the most useful adjustments include:
- Light: Tweaking exposure, brilliance, highlights, shadows, brightness, and contrast
- Color: Adjusting saturation, vibrance, temperature, tint, and color cast
- Selective Color: Targeting and adjusting specific color ranges in your image
- Levels: Fine-tuning the tonal range and color balance
- Sharpen: Bringing out details and edges for a clearer image
- Definition: Adding midtone contrast to make features pop
- Noise Reduction: Smoothing out graininess, especially in low light shots
To use an adjustment, just click on its name in the right sidebar. Sliders will appear allowing you to precisely control the intensity of the effect. The best part? You can see a live preview of your changes on the image.

Pro tip: Holding down the Option key while dragging a slider will show you a before/after comparison. It‘s a great way to check your work as you go!
Filters Tab
Want a cool look for your photo with just one click? The "Filters" tab has you covered with eight preset styles:
- Vivid
- Dramatic
- Mono
- Silvertone
- Noir
Applying a filter is as easy as clicking its thumbnail. You can then use the slider at the bottom to dial in the strength of the effect.

I personally love using the Vivid filter to make landscape shots really sing. Give it a try on your travel photos!
Crop Tab
In the "Crop" tab, you can change the framing of your image, straighten tilted horizons, rotate, and even flip your photo. Just grab the handles on the crop rectangle and drag to your desired proportions.
If you need a specific aspect ratio for social media, click the "Aspect" button and choose from common presets like Square, 4:3, and 16:9.

To rotate your image 90° clockwise or counterclockwise, click the arrow buttons in the bottom-right corner. The "Flip" button lets you create a mirror image of your photo—perfect for getting text in the right direction.
And that‘s all there is to it! With these simple tools, you can make your photos look their best without ever leaving the Photos app.
Option 2: Using Third-Party Photo Editing Apps
While the Photos app is great for quick edits, sometimes you need more powerful tools and features. That‘s where third-party photo editors come in to pick up the slack.
According to market research firm SimilarWeb, the most popular paid photo editing app for Mac is Photoshop, with over 20 million monthly users worldwide. However, with its steep learning curve and even steeper price tag ($21/month), it‘s overkill for most casual users.
Fortunately, there are several more affordable (and less intimidating) options that still pack a punch when it comes to advanced editing capabilities. Here are my top three picks:
1. Affinity Photo

Here‘s a quick comparison table of these three apps:

| Portrait retouching | Yes | Yes | Some |

Of course, this is just a small sampling of the many third-party photo editors available for Mac. Other popular options include CameraBag Pro, Acorn, and Capture One. And if you‘re on a tight budget, open-source programs like GIMP and Darktable are completely free!

Tips for Optimizing Your Photo Editing Workflow on Mac
No matter which editing tools you choose, there are a few best practices that can help streamline your workflow and get better results:
- Shoot in RAW format if your camera supports it. RAW files contain more data than JPEGs, giving you greater flexibility when editing exposure, white balance, and color.
- Use the histogram to keep an eye on exposure and avoid clipping highlights or shadows. Most photo editors include this handy graph.
- Make non-destructive edits with layers and masks. That way, you can always go back and refine your adjustments without permanently altering the original image.
- Zoom out to view your photo at 100% periodically. It‘s easy to get caught up in pixel peeping, but seeing the whole image gives you a better sense of your overall edits.
- Calibrate your display for accurate colors. Use your Mac‘s built-in Display Calibrator or a third-party hardware calibration tool to ensure you‘re seeing colors correctly.
- Take advantage of iCloud Photos to access your edits on all your devices. Most popular photo editors can read from and save to your iCloud Photos library.
- Develop a consistent editing style. Rather than chasing trends, figure out what look resonates with you and stick with it. This will make your photos more recognizable.

By implementing these tips into your editing process, you‘ll start seeing improved results in no time!
