I experience the same on my Apple M3 MacBook Air after upgrading to MacOS 26.

Here's my crash log: https://pastebin.com/A95s7yq3

Thank you for letting me know. I will fix as soon as I am on Tahoe.

AI analysis if the issue :) (not sure if true) Root cause: fman 1.7.3 ships an old Intel-only Python 3.6 + PyObjC stack. On macOS Tahoe 26.0 (25A354), the bundled PyObjC crashes while enumerating Objective‑C classes during bundle loading. This happens under Rosetta and is a known brittle path in older PyObjC builds. • Fix that actually lasts: fman needs an updated build (Apple‑silicon native, modern Python/PyQt, PyObjC ≥ 11)

A temporary workaround, Obviously breaking some functionality. cd "/Applications/fman.app/Contents/MacOS" mv objc objc.disabled

Reverting with : mv "/Applications/fman.app/Contents/MacOS/objc.disabled" "/Applications/fman.app/Contents/MacOS/objc"

I found on YouTube this file manager application, "FMAN," which was highly recommended, along with another. However, since it does not work on my macOS Tahoe 26.1 (25B78), I will remove the installation of fman and wait till a revised version works, as I am not into modifying Python resources. Hopefully it will be soon. When it is, I would appreciate a notification to try it out.
