ActivePresenter 10.1.1 Fails to Launch on macOS 26.3 (Apple Silicon M4) – Boost Interprocess Error

ActivePresenter Support Questions
1

Hello,

I’m encountering a consistent startup failure with ActivePresenter 10.1.1 after updating to macOS 26.3.

System Environment

  • macOS: 26.3 (25D125)

  • Hardware: Apple Silicon M4

  • ActivePresenter: 10.1.1

  • Executable architecture: x86_64

  • Running via Rosetta 2

The binary confirms as:

Mach-O 64-bit executable x86_64

Error

On launch:

Interprocess exception (boost: 7, native: 2): No such file or directory

If launched manually:

arch -x86_64 /Applications/ActivePresenter.app/Contents/MacOS/ActivePresenter

The process initializes but either hangs or terminates with the Boost interprocess exception.

Troubleshooting Performed

  • Full uninstall and clean reinstall

  • Removed:

    • ~/Library/Application Support/ActivePresenter

    • ~/Library/Preferences/com.atomisystems.ActivePresenter.plist

    • ~/Library/Caches/com.atomisystems.ActivePresenter

    • ~/Library/Saved Application State/com.atomi.activepresenter.savedState

  • Verified /private/var/tmp permissions:

    drwxrwxrwt

  • Confirmed Rosetta 2 installed successfully

  • Verified notarization:

    spctl --assess --verbose /Applications/ActivePresenter.app
accepted (Notarized Developer ID)

Issue persists after clean reboot.

Relevant Log Output (macOS Console)

During launch, the app:

  • Registers with LaunchServices

  • Connects to TCC

  • Initializes AppKit

  • Begins window restoration

Then fails with Boost interprocess error.

Example excerpts:

ActivePresenter: CFBundleShortVersionString="10.1.1"
ActivePresenter: NSApp begin modal window
ActivePresenter: Restoring windows
ActivePresenter: WARNING: Secure coding is automatically enabled for restorable state
ActivePresenter: Interprocess exception (boost: 7, native: 2)

This suggests failure during shared memory / semaphore initialization under Rosetta.

Context

The application was working previously.

Failure began after macOS 26.3 update and system reboot.

Given that the macOS build is Intel-only (x86_64), this may relate to:

  • Boost interprocess POSIX shared memory

  • macOS 26.3 IPC changes

  • Rosetta translation behavior on Apple Silicon

Questions

  1. Is ActivePresenter 10.1.1 officially compatible with macOS 26.3 on Apple Silicon?

  2. Is there a native ARM64 (Apple Silicon) macOS build available?

  3. Is this a known Boost IPC compatibility issue under Rosetta?

  4. Is a patch planned?

Happy to provide full log traces if needed.

Thank you.

Hi,

Could you please try removing the ActivePresenter filename as mentioned in this thread and see if it helps?

Regards,

Hi, Thanks. It seems to work for now. I found the ActivePresenter* file in the user dir and deleted it.
