Access your DAT Loadboard workspace directly from your desktop.
Opening on macOS for the first time? Because the app isn't from the Mac App Store, macOS shows a security warning the first time. Two ways to open it:
Easiest: after the warning, open System Settings → Privacy & Security, scroll down, and click Open Anyway.
Or drag the app into Applications, then paste this one line into Terminal and press Enter (then it opens with a normal double-click, no warning):
xattr -dr com.apple.quarantine "/Applications/DAT Loadboard V4.app"
Linux: make the file executable first — chmod +x the downloaded .AppImage, then run it.
