How to animate an object in Keynote on Mac: step by step for Keynote 15.4

Keynote calls every animation a build. Apple's guide sorts builds into three tabs in the Animate sidebar. Build In controls how an object arrives on the slide. Action changes an object while it stays on the slide. Build Out controls how it leaves. Move is an Action effect that carries the object along a path. The steps below match Keynote 15.4, the version Apple's current guide covers.

What you need before you start

Start with the version. Apple's Keynote 15.4 guide says Keynote 15.4 for Mac requires macOS 26 or later. To check your version, open Keynote and choose Keynote > About Keynote. If the number is lower, update before you follow these steps, because the menus may look different.

You do not need a subscription to animate. Apple says you can keep using Keynote, Pages, Numbers, and Freeform for free. Creator Studio adds premium templates, royalty-free photos and graphics, and intelligence features. Apple lists that subscription at $12.99 per month or $129 per year after a one-month free trial.

Add a Build In effect so the object enters the slide

Build In is the choice most people want first. Click the object, then click the Build In tab in the Animate sidebar. Click Add an Effect and pick an animation. Keynote plays a preview as soon as you pick one, so you can judge it before you commit. To try a different effect, click Change and pick another. The steps stay the same for every effect in the list.

Add an Action effect to change the object in place

Action effects keep the object on the slide and change it while it sits there. Apple's guide describes controls that are simple sliders and fields. Opacity uses a slider, and dragging it fully left ends with the object invisible. Rotate uses a Clockwise pop-up menu plus Angle and Rotations fields. Scale uses a slider, or you can drag the white square on the transparent ghost object.

• Opacity: drag the slider fully left to end with the object invisible.
• Rotate: pick a direction in the Clockwise pop-up menu, then set Angle and Rotations.
• Scale: drag the slider, or drag the white square on the transparent ghost object.
• Move: drag the object to its start point and the ghost to its end point.

Move an object along a motion path

Move is the effect people usually mean when they ask about a path. Select the object, open the Action tab, and choose Add an Effect > Move. Drag the opaque object to the start of the path and the ghost to the end. Drag the white dots to bend the line, then set duration and acceleration. Select Align to path if you want that option, and click Preview to watch it.

If the ghost is missing, click the object, then click the red diamond beneath it. That brings the ghost back so you can drag it. Set the start and end points first, then adjust duration. That order keeps the path easy to read while you work.

Make an object leave the slide with Build Out

Build Out handles exits. Click the object, click the Build Out tab in the Animate sidebar, then click Add an Effect and pick an effect. Apple says the steps match Build In, with the Build Out tab instead. A common setup pairs an entrance with Build In and an exit with Build Out, so the object comes in, does its job, and leaves.

Control order and timing with Build Order

Add a second build to an object, and Keynote needs to know when each one runs. Scroll to Build Order at the bottom of the Animate sidebar. Each build appears there with a thumbnail. Keynote 11.0 added those thumbnails to make complex builds easier to edit. Select a build, then use its Start pop-up menu to choose when it runs.

Command-click selects several builds at once, so you can change them together. Use the Delay setting after After Transition or After Build when you want a pause. Test the order by playing the whole show, not just one build. A sequence that looks right in one preview can still feel off when it plays in order.

Remove an animation you no longer want

To remove every build of one type, click the Build In, Build Out, or Action tab, click Change, and choose None. To remove a single build, open Build Order, select that build, and press Delete. Select the right build before you press Delete, because the list shows each one by its place in the order.

Preview and play the animation

Use Preview in the Animate sidebar to test the effect you are editing. To see the whole deck, play the show with ⌥⌘P. Option-click the Play button in the toolbar to play from the beginning. Apple's shortcut list names no shortcut for Animate, Preview, or Build Order, so use the mouse for those steps.

Keyboard shortcuts while you present

While you present, the arrow keys move through builds. Shift-Right Arrow goes to the next build or slide without playing its animation. Shift-Left Arrow or Shift-Up Arrow goes back to the previous build. Use these during a rehearsal when you want to skip ahead without waiting for each animation. ⌥⌘I hides or shows the inspector sidebars while you edit.

Animate text, lists, tables, and charts

Text, lists, tables, and charts need extra settings. Click Animate in the toolbar, add an effect, then open the Delivery pop-up menu. Pick a choice such as By Bullet Group. Next, use the Build from pop-ups to choose which pieces build in. A bulleted list can then reveal one point at a time without a separate animation for each bullet.

Check the animation on iCloud.com before you share

If you share the deck through iCloud.com, check the animations there before the talk. Apple says unsupported transitions and builds appear as Dissolve. The original build stays in the file, and you can edit it in Keynote for Mac, iPhone, or iPad. Action builds cannot be viewed or edited on iCloud.com, although they remain in the presentation.

On iCloud.com, 3D objects play as 2D during playback, and animations follow 2D rules. The Blur property for builds cannot be viewed or edited there either. Apple's pages do not confirm whether Build Order, Delivery, Preview, or Move paths work on iCloud.com, so test those before you present.

Which builds appear in which Keynote version

Keynote 15.3 added new transitions and builds, including shift, radial wipe, and character blur. Keynote 15.4 release notes list no animation changes. Keynote 13.2 added embedded USDZ animation playback for 3D objects. Keynote 12.1 added animated themes and dynamic backgrounds. If you need a 15.3 build in a shared file, confirm that everyone who opens it runs 15.3 or later.

Common mistakes that make animations look wrong

• Setting every build to On Click. Your audience waits for each click, even when two builds belong together.
• Forgetting the ghost. For Move, the ghost marks the end point, so a missing ghost makes the path hard to set.
• Testing one build in the sidebar and never playing the whole show.
• Using Action builds in a file you plan to edit on iCloud.com. Those builds cannot be viewed or edited there.
• Adding a Delay and forgetting it. Check Build Order again after every change to the order.

Where to go next

Once the object moves the way you want, the next step is usually media. How to add a video to a slide in Keynote on Mac walks through that. If you present from notes, how to add presenter notes in Keynote on Mac covers the steps. When the deck needs to become a file, the movie export guide explains that step.
