Preview automatically saves changes for you as you work, so you don’t have to save your changes manually. You can save a document manually if you want to, for example, save a copy of the document in a different location.

Preview periodically saves “snapshots” of your document, called versions, so that you can view the document as it appeared in the past and revert to a previous version. When you’re actively editing a document, Preview saves a version at least every hour, and more often if you’re making significant changes. Preview also saves a version when you open a document, save or duplicate a document, lock or rename a document, or revert to a previous version.

Manually save a Preview document

Mac Preview User Manual User

When you create a document from the Clipboard, your changes are saved automatically as you edit. However, you must save it to give it a name and store it in a location.

    • To save the document using a different filename, location, or format: Press and hold the Option key and choose File > Save As.

      If you have iCloud set up and iCloud Drive turned on, you can save your documents in the Preview folder in iCloud Drive by clicking the Where pop-up menu, choosing “Preview — iCloud,” then clicking Save. See Use iCloud Drive to store documents.

      Tip: You can also hold the pointer over the document title and click the arrow to save the document or change its location.

Create a copy of a document

  1. In the Preview app on your Mac, open a PDF or image that you want to copy.

  2. Do any of the following:

    • To create a copy of a document to edit in Preview: Choose File > Duplicate. When you’re ready to save the document, choose File > Save, enter a name, select a file format, then choose where you want to save it.

    • To create a copy of a document so you can archive it or convert it to another format: Choose File > Export.

Revert to the last saved or opened version

  1. In the Preview app on your Mac, open a PDF or image that you want to revert.

  2. Choose File > Revert To > Previous Save [date, time].

    If you edit the PDF or image, choose File > Revert To > Last Saved [date, time] or File > Revert To > Last Opened [date, time].

Examine, recover, or duplicate previous versions

  1. In the Preview app on your Mac, choose File > Revert To > Browse All Versions.

  2. Click a gray tick mark along the timeline on the right to display various versions of your document.

  3. Do one of the following:

    • To restore your document to the state of a particular version: Display that version, then click Restore.

    • To create a new untitled document that duplicates a particular version: Display the version, press and hold the Option key and click Restore a Copy.

Submitting apps to the App Store using Xcode

Mac Preview User Manual Download

If you’re an Apple Developer Program member, Xcode provides an integrated workflow to prepare and submit apps to App Store. You should use the latest version of Xcode available on the Mac App Store to submit your apps, or when available, the latest GM seed release from the Downloads page.

Do not submit apps built using beta software, as beta versions of Xcode, Operating Systems, and SDKs are for development and testing only.

Invalid private key and certificate pairing

If you received an error message saying, 'Xcode could not find a valid private-key/certificate pair for this profile in your keychain.' This error message indicates that the Keychain Access application on your Mac is missing either the public or private key for the certificate you are using to sign your app.

This often happens when you are trying to sign and build your app from a different Mac than the one you originally used to request your code signing certificate. It can also happen if your certificate has expired or has been revoked. Ensure that your app’s provisioning profile contains a valid code signing certificate, and that the Keychain Access application on your Mac contains that certificate, the private key originally used to generate that certificate, and the WWDR Intermediate Certificate.

For instructions on how to resolve this and other code signing errors, review the Code Signing Support page.
