FFmpeg problems

Hi, I’m having an ongoing issue where OpenToonz cannot detect FFmpeg on macOS. I’ve been trying to fix this for over two days. Here’s what I’ve done so far:
• Running OpenToonz v1.7.1 on macOS Sonoma 14.7.6 (M1 Mac).
• FFmpeg is downloaded directly from ffmpeg.org (static build). I’ve placed it in a folder on the desktop and elsewhere, including external drives.
• When I go into Preferences → Import/Export and try to browse for FFmpeg, the folder appears empty, even though FFmpeg is definitely inside.
• I’ve tried:
• Manual path entry in Preferences
• Making FFmpeg executable with chmod +x
• Removing Apple quarantine with xattr -d com.apple.quarantine
• Confirming FFmpeg runs in Terminal (./ffmpeg shows all expected output)
• Using Homebrew to install FFmpeg (also didn’t work)
• Rebooting after every step
• Making Automator drag-and-drop tools to confirm FFmpeg runs
• Freeing up over 100GB of space
• Testing on both internal and external drives
• Downgrading OpenToonz to a slightly older version — issue still persisted

The issue isn’t that FFmpeg won’t run — it’s that OpenToonz won’t detect it when browsing to the file in Preferences.

I would really appreciate any help. Thank you.

I'd also like to add that I've downloaded 4-5 different versions of FFmpeg by now, and Opentoonz won't recognize any of them.
