I compiled and installed the v96 ARM version of the DMG file on macOS 26, but some UI elements in the application are having issues, such as the progress bar in the lower right corner and missing button styles. Have you encountered this problem with your version compiled on macOS 15?
I haven’t noticed that issue at all with my build. I’m on macOS 15, and building with the Xcode 26 SDK.
After a fair amount of fighting with the build script though, I was able to get a standalone version of the MKVToolNix.app without it relying on dynamic libraries present on the system (eg. installed through homebrew). I’ll try to get that upstreamed into the build script when I have some time.
This allowed me to get the app signed as well as notarized, to get rid of the gatekeeper checks that usually appear when downloading the app. I’ve uploaded it here for anyone who doesn’t want to go through the trouble of building it (or has issues building it).
Note: This version is built for Apple Silicon, and will not work on Intel macs.
These UI problems come from QT bugs when using macOS 26 SDK and have been fixed in some newer version of QT. So when you have this it’s because you’re using an older QT version with the macOS 26 SDK. To fix this you need to compile with an older SDK or use the newest version of QT.
No wonder this problem didn’t occur when the GUI called a Qt installed via brew; changing the version number to 6.10.2 in the build script and then compiling solved it.
Many Thanks.
