25.03.29 not macOS 11.x compatible

What is your operating system?
MacOS Big Sur 11.7.10

What is your Shotcut version (see Help > About Shotcut)?
25.03.29

Can you repeat the problem? If so, what are the steps?
The error message says it was built for MacOS 12 (contrary to the Download page which says the “macOS 11 - 14”)

Will not be fixing, I’ll just update the download page.

Sure. FWIW the relevant error message is:

Dyld Error Message:
Symbol not found: _kIOMainPortDefault
Referenced from: /Applications/Shotcut.app/Contents/MacOS/…/Frameworks/QtCore.dylib (which was built for Mac OS X 12.0)
Expected in: /System/Library/Frameworks/IOKit.framework/Versions/A/IOKit

I’m going thru the old downloads to see what’s the latest version that works on Big Sur…

We upgraded Qt, use their build of the frameworks, and I think it updated the minimum version: Qt for macOS | Qt 6.8

Yes, I see 6.7 it was macOS 11: Qt for macOS | Qt 6.7

The last version to support it is 24.11
