In June 2014, Apple announced that development of Aperture has been discontinued. Since then, Apple has released six major macOS upgrades. For technical reasons, macOS Mojave is the last version of macOS to run Aperture. Starting with macOS Catalina, Aperture is no longer compatible with macOS.

When finished copying, hold down the option key ⌥ while launching the Photos app. Click Other Library and navigate to the new location on the external device. In the Photos app, click on Preferences General and select ‘Use as System Photo Library’. This is mandatory if you use iCLoud with your Photo library. Ok, now you can get rid of the iPhoto Library from Pictures folder (assuming you have backup on your old Mac). Delete iPhoto Library from Pictures folder and empty the Trash. If you see Photos Library in Pictures, trash it as well and empty trash. Then create a new photos library by holding down Option when you open Photos.
To continue working with your Aperture photo libraries, you must migrate them to another photo app. You can migrate them to the Photos app, which is included with macOS Yosemite or later, or migrate them to Adobe Lightroom Classic or another app. You should do this before upgrading to macOS Catalina.
Migrate your library to Photos
If you're using macOS Mojave or earlier
Iphoto To Photos Mac
Follow these steps if you're using macOS Mojave or earlier:
- Open Aperture.
- Choose Aperture > Preferences, click the Previews tab, then change the Photo Preview setting to Don't Limit. Close the preferences window.
- From the list of projects in the Library inspector, select all of your projects. For example, click the first project listed, then press and hold the Shift key while clicking the last project.
- Click the Browser layout button in the toolbar, so that all photos are shown as thumbnails.
- Choose Edit > Select All to select all of your photos.
- Press and hold the Option key, then choose Photos > Generate Previews.
- Aperture now generates full-size previews for every photo in your library. To follow its progress, choose Window > Show Activity from the menu bar. Quit Aperture when processing is complete.
- Open the Photos app, then choose your Aperture library when prompted, as pictured above. If you aren't prompted to choose a library, press and hold the Option key while opening Photos. If your Aperture library isn’t listed, click Other Library, then locate and choose your library.

When Photos shows the photos from your Aperture library, migration is complete. Learn more about how Photos migration works and how Photos handles content, metadata, and smart albums from Aperture.
If you're using macOS Catalina
Iphoto To Photos On Mac
Starting with macOS Catalina, Aperture is no longer compatible with macOS. If you upgraded to macOS Catalina before migrating your library to Photos, follow these steps:
- Install the latest macOS Catalina updates. Your Mac must be using macOS Catalina 10.15.1 or later.
- If you migrated your library to Photos after installing macOS Catalina 10.15 but before updating to macOS Catalina 10.15.1, complete these steps before continuing:
- Select your Aperture library in the Finder. By default, it's named Aperture Library and is in the Pictures folder of your home folder.
- Choose File > Get Info. An Info window for your Aperture library opens.
- In the Name & Extension section of the Info window, replace .migratedphotolibrary at the end of the file name with .aplibrary. Then close the window.
- Open the Photos app, then choose your Aperture library when prompted, as pictured above. If you aren't prompted to choose a library, press and hold the Option key while opening Photos. If your Aperture library isn’t listed, click Other Library, then locate and choose your library.
When Photos shows the photos from your Aperture library, migration is complete. Learn more about how Photos migration works and how Photos handles content, metadata, and smart albums from Aperture.
Migrate your library to Adobe Lightroom Classic
Migrate Iphoto To Photos
Adobe Lightroom Classic version 5.7 and later includes a built-in tool for migrating Aperture libraries to Lightroom catalogs.
If you’ve upgraded to macOS Catalina, learn about compatibility with Lightroom Classic.
When an Aperture library is migrated to Lightroom, your library's organization, metadata, and image adjustments are preserved, with some exceptions:
- RAW files are migrated, but Aperture's non-destructive adjustment layer does not. Lightroom’s migrator tool includes an option to export and migrate Aperture’s full-size JPEG previews for edited images. If you want to preserve your Aperture edits in another format, export the edited images from Aperture first, then reimport them into Lightroom after migrating your library.
- Projects, folders, and albums are migrated to Lightroom collections and collection sets.
- Faces, color labels, and stacks are migrated as keywords.
- Rejected images are migrated to a collection.
- Slideshows are migrated as collections.
- Smart Albums and custom metadata fields aren't migrated.
- Album organization is alphabetical, so manual sidebar organization might not be preserved.
- Custom metadata fields aren't migrated.
Export your Aperture library
You can also export the contents of your Aperture library to back it up or to import into another app.
Back up your library
Mac Migrating Photos From Iphotos To Photos Apps
Before following any of these steps, it's a good idea to create a backup of your photo library, even if you use iCloud Photos. You can use Time Machine, use a third-party backup solution, or copy the library to an external drive. By default, your photo library is stored in the Pictures folder within your home folder.
Make sure that your software is up to date
Photos is part of the Mac operating system. You can avoid or fix many issues by running the most up-to-date version of macOS. Learn more about updating the software on your Mac.
If you use RAW images in Photos, learn more about the digital camera RAW formats supported by iOS, iPadOS, and macOS.
If you have trouble migrating an existing iPhoto or Aperture library to Photos
You might see an alert message when you first open Photos or migrate an existing iPhoto or Aperture library. Learn what to do if Photos can’t copy or create a library.
If the Media Browser isn't showing your photos and videos
Use the Media Browser to make images from your photo library available in other apps, like Pages and iMovie. The Media Browser shows only the contents of the Photos library designated as the System Photo Library. If you have more than one Photos library—and the one you're using isn't set as the System Photo Library—the Media Browser won't show its contents.
Follow these steps to designate the current library as the System Photo Library:
- Choose Photos > Preferences.
- Click the General button at the top of the Preferences window.
- Click Use as System Photo Library.
If you're having other issues with Photos
If you're experiencing other issues—like missing or blank photo thumbnails, unexpected behavior, or if Photos won’t open—try to see if it's an issue with your library by following these steps.
Create a new Photos library and see if your issues persist:
- Quit Photos.
- Press and hold the Option key while you open Photos.
- In the dialog that appears, click Create New.
- Give your new library a name, then click OK. Note whether Photos opens successfully with this new library.
To return to your main Photos library, quit Photos. Then open it again while holding the Option key, select your main library, and click Choose Library.
Alternatively, you can open Photos in another user account on your Mac and note whether Photos opens successfully.
If Photos opens with the new library, or in a different user account, it might mean that there's an issue with your library. Follow the steps to use the Photos library repair tool on your main Photos library.
