PowerPoint for Mac Crashes on M1 With Rosetta-Only Add-Ins: Fix

PowerPoint for Mac crashes immediately after launch or when you open a specific presentation on Apple Silicon M1 Macs. The crash occurs because a third-party add-in was compiled for Intel processors and runs under Rosetta 2 emulation. This article explains why Rosetta-only add-ins cause PowerPoint to become unstable and shows you how to identify and remove the problematic add-in to restore normal operation.

Why PowerPoint Crashes on M1 Macs With Rosetta-Only Add-Ins

PowerPoint for Mac on Apple Silicon runs natively as a Universal Binary. It does not use Rosetta 2 translation. When you install a COM add-in compiled only for Intel x86-64 processors, PowerPoint loads that add-in inside its native process. The incompatible Intel code causes a memory access violation or a thread mismatch, which results in an immediate crash or a hang that forces you to force-quit the application.

The crash can happen in three scenarios:

• PowerPoint crashes right after you click the icon to launch it.
• PowerPoint opens but crashes the moment you create or open a presentation.
• PowerPoint works normally until you use a specific feature provided by the add-in.

The root cause is always the same: the add-in contains Intel-only compiled code that cannot run correctly under PowerPoint’s native ARM64 process.

Steps to Remove the Rosetta-Only Add-In and Stop the Crash

Perform these steps in order. You will disable the add-in first, then delete its files if the crash persists.

Step 1: Open PowerPoint in Safe Mode

1. Hold the Option key while launching PowerPoint
   Press and hold the Option key on your keyboard. Click the PowerPoint icon in the Dock or Applications folder. Keep holding the Option key until you see a dialog that asks if you want to open PowerPoint in Safe Mode. Click Continue.
2. Confirm Safe Mode is active
   Safe Mode disables all add-ins and customizations. If PowerPoint opens without crashing, the problem is confirmed to be a third-party add-in.

Step 2: Disable the Add-In From Within PowerPoint

1. Go to Tools > PowerPoint Add-Ins
   With PowerPoint still in Safe Mode, click the Tools menu in the menu bar and select PowerPoint Add-Ins. This opens the Add-Ins dialog.
2. Select COM Add-Ins and click Go
   In the Manage dropdown at the bottom of the dialog, choose COM Add-Ins. Click the Go button. You will see a list of all installed COM add-ins.
3. Uncheck the suspect add-in
   Clear the checkbox next to each add-in that you suspect is causing the crash. If you are unsure which one is the problem, uncheck all of them. Click OK to close the dialog.
4. Restart PowerPoint normally
   Quit PowerPoint completely. Launch it again without holding the Option key. If the crash is gone, the add-in you disabled was the cause.

Step 3: Delete the Add-In Files From the Library Folder

Disabling the add-in prevents it from loading, but the files remain on your Mac. To remove the add-in completely, delete its files from the User Content folder.

1. Open Finder and go to the Library folder
   In Finder, click the Go menu in the menu bar. Hold the Option key to reveal the Library option. Click Library.
2. Navigate to the Add-Ins folder
   Inside the Library folder, open the Group Containers folder. Then open the folder named UBF8T346G9.Office. Open User Content, then open Add-Ins.
3. Move the add-in file to the Trash
   Look for files with extensions .ppam, .ppa, or .dll. Drag the file that matches the add-in you disabled to the Trash. You may need to enter your administrator password.
4. Empty the Trash and restart PowerPoint
   Empty the Trash from the Finder menu. Restart PowerPoint. The add-in is now gone.

If PowerPoint Still Has Issues After Removing the Add-In

PowerPoint crashes even in Safe Mode

If PowerPoint crashes during Safe Mode startup, the problem is not an add-in. The issue could be a corrupted Normal.dotm template or a damaged font cache. Reset the PowerPoint preferences by quitting PowerPoint, then go to ~/Library/Preferences. Move the file com.microsoft.Powerpoint.plist to the Desktop. Restart PowerPoint. A new preference file will be created.

The add-in is required for work and has no native version

Some business-critical add-ins have not been updated for Apple Silicon. As a temporary workaround, you can run the Intel version of PowerPoint under Rosetta 2. Right-click the PowerPoint app in the Applications folder and choose Get Info. Check the box labeled Open using Rosetta. Launch PowerPoint. It will run under Intel emulation, and Intel-only add-ins will work. Performance will be slower than native, but the crash will stop.

PowerPoint crashes when exporting or saving with the add-in disabled

If the crash persists after disabling all add-ins, the presentation file itself may be corrupted. Open PowerPoint in Safe Mode and create a new blank presentation. Use File > Open to open the problematic file. If it crashes again, the file is damaged. Recover content by using File > Open and selecting the Recover Text from Any File option in the Enable dropdown.

PowerPoint for Mac M1 Native vs Rosetta Add-In Compatibility

Item	Native Apple Silicon (ARM64)	Rosetta 2 Emulation (Intel x86-64)
PowerPoint binary type	Universal Binary (ARM64 + Intel)	Intel-only binary
Add-in compatibility	Only ARM64 or Universal Binary add-ins	Intel-only add-ins work
Performance	Full native speed	Slower due to translation overhead
Crash risk with Intel add-in	High – immediate crash on load	None – add-in runs under emulation
Recommended for daily use	Yes, if all add-ins are native	Only as temporary workaround

PowerPoint for Mac on M1 Macs crashes when a Rosetta-only add-in loads because the add-in contains Intel machine code that cannot execute inside the native ARM64 process. Disabling or removing the add-in from Tools > PowerPoint Add-Ins resolves the crash. If the add-in is essential, running PowerPoint under Rosetta 2 via the Get Info checkbox is a viable temporary fix. Check the add-in developer’s website regularly for a native Apple Silicon update to regain full performance and stability.
