Fix PowerPoint Crashes on Mac (Missing ADAL4.framework Error)
Question details
Microsoft PowerPoint crashes immediately upon launch on an Apple Silicon Mac due to a dynamic linker error indicating a missing or invalid ADAL4.framework.
- Product
- Microsoft PowerPoint
- Device & OS
- Mac (macOS 13.1, Apple M1)
- Scenario
- Attempting to launch the Microsoft PowerPoint application on a Mac.
- Observed behavior
- The application fails to open and crashes instantly, generating an EXC_CRASH/SIGABRT error log that points to a missing or invalid ADAL4.framework library.
Ensure you have your Microsoft account login credentials handy, as reinstalling the software will require you to sign back in to activate your license.
Perform a Clean Reinstallation of Microsoft PowerPoint
Uninstalling and reinstalling PowerPoint replaces the missing or corrupted ADAL4.framework files, resolving the application crash.
The ADAL4.framework is a core component used for Microsoft authentication. If it becomes corrupted or is missing a valid code signature, the application will forcefully quit. A clean installation is the most reliable way to restore these system files.
Ensure all Microsoft Office applications (Word, Excel, Outlook) are completely closed before proceeding.
Open the 'Applications' folder in Finder, locate Microsoft PowerPoint, and drag it to the Trash. Empty the Trash to remove the files completely.
Navigate to the official Microsoft website or the Mac App Store to download the latest installer for Microsoft PowerPoint or Microsoft 365.
Run the downloaded installer. Once installed, go to 'System Settings' > 'General' > 'Software Update' to ensure your macOS is up to date, which helps prevent compatibility issues.
Run a Malware Scan on Your Mac
An invalid code signature or missing framework file can sometimes be the result of a malware infection interfering with application files.
Use WPS Office to Open and Edit Your Presentations Seamlessly

- 1. Download WPS Office: Visit the official WPS website, download the macOS version, and complete the installation process.
- 2. Launch Presentation Module: Open WPS Office from your Applications folder and click on the Presentation icon.
- 3. Open Your File: Click 'Open' and select your existing PowerPoint file to continue editing instantly.
Frequently Asked Questions
What is the ADAL4.framework on a Mac?
ADAL stands for Active Directory Authentication Library. It is a component used by Microsoft applications to handle user authentication and sign-in processes. If this library is missing or invalid, the app cannot verify your license and will crash.
Does the Apple M1 chip cause this PowerPoint crash?
The crash is typically related to software corruption or invalid code signatures during a faulty update rather than the Apple M1 chip itself. However, ensuring you are using the latest universal binary version of Office helps guarantee optimal compatibility with Apple Silicon.
Will uninstalling PowerPoint delete my presentation files?
No, moving the Microsoft PowerPoint application to the Trash only removes the software. It will not delete your saved .pptx files, which are safely stored in your local folders or cloud storage.
