I tried homebrew, and that compiles, but doesn't run. (I've uninstalled it from there).

I noticed a fix on a recent thread - the latest version executable files don't fail.

Compatibility with macOS v15.4+ was fixed in v1.41.0 final, see the changelog. And FWIW, https://github.com/ldc-developers/ldc-developers.github.io/blob/master/LATEST_BETA points to v1.41.0 final (as always whenever there's no newer beta than the latest final).

I don't think home brew has the latest version. How do I install ldc with out home brew?

There are a plethora of options!

1. Just download archive from GitHub Releases.
   Extract it to your favorite folder.
   Add this folder to the PATH.
   (unlock externally downloaded binary files - specific macOS protection)
   Done.

2. This is the script from macOS D maintainer - which is installing LDC with some common tools into /opt/SDKs. Better to remove /opt/SDKs first.

# Setup SDK Root
if [[ ! -d /opt/SDKs ]]; then
    sudo mkdir -p /opt/SDKs/
    sudo chmod -R 777 /opt/SDKs

    curl -o /opt/SDKs/init.sh https://gist.githubusercontent.com/LunaTheFoxgirl/60cda49e9fd9b95c837f2d4c09706523/raw/7e9fee07357459dcc55df8de5ae4f40a6d5a34a4/init.sh
    chmod +x /opt/SDKs/init.sh
    echo "source /opt/SDKs/init.sh" | sudo tee -a /etc/profile
fi

echo "Setting up .buildtmp..."
mkdir .buildtmp;
cd .buildtmp

# 1. Install LDC into our new SDK Root
if [[ ! -d /opt/SDKs/ldc2 ]]; then
    echo "Downloading LDC2..."
    mkdir -p /opt/SDKs/ldc2
    curl -L https://github.com/ldc-developers/ldc/releases/download/v1.41.0/ldc2-1.41.0-osx-universal.tar.xz -o ldc2.tar.xz

    echo "Extracting LDC2..."
    tar xf ldc2.tar.xz

    echo "Installing LDC2...."
    mv ldc2-1.41.0-osx-universal/* /opt/SDKs/ldc2
    export PATH=/opt/SDKs/ldc2/bin:$PATH
    rm -r ldc2*

    # 2. Install new DUB
    echo "Building latest dub from source..."
    git clone https://github.com/dlang/dub
    dub build --root=dub/ --build=release

    echo "Staging dub into /opt/SDKs/ldc2/bin..."
    cp dub/bin/dub /opt/SDKs/ldc2/bin/
fi

# 3. Build serve-d and DCD from latest source.
echo "Rebuilding serve-d and dcd..."
if [[ ! -d "/opt/SDKs/serve-d" ]]; then
    echo "Install directory not found, creating..."
    mkdir -p /opt/SDKs/serve-d/bin
    mkdir -p /opt/SDKs/dcd/bin
fi

git clone https://github.com/Pure-D/serve-d
git clone https://github.com/dlang-community/DCD

dub build --root=dcd --dest=/opt/SDKs/ --build=release --config=client
dub build --root=dcd --dest=/opt/SDKs/ --build=release --config=server
dub build --root=serve-d --build=release
cp serve-d/serve-d /opt/SDKs/serve-d/bin/

echo "Cleaning up..."
cd ..
rm -rf .buildtmp

echo "Done!"

3. There is also this project https://code.dlang.org/packages/ldcup

Homebrew has the latest version, and before that the maintainer back ported the fix also to prior versions.
