Download YouDJNow Desktop
One free app that pushes guest requests straight into Serato, VirtualDJ and rekordbox, badges every request In Library / Not In Library from your own local music folders, and opens a chromeless TV window for your customer screen.
Download, unzip, drag to Applications (Mac) and open. Current Mac builds aren't Apple-signed yet, so macOS shows a “damaged and can't be opened” warning the first time — get the one-time xattr fix here.
Mac says “damaged and can't be opened”? Paste this once.
If the copy in Downloads opens but the copy in Applications is black, the old Applications copy was never actually replaced. Leave the working YouDJNow.app in Downloads, close YouDJNow, then paste this entire block into Terminal:
pkill -x YouDJNow 2>/dev/null || true
pkill -x "YouDJNow Desktop" 2>/dev/null || true
rm -rf "/Applications/YouDJNow.app" "/Applications/YouDJNow Desktop.app"
ditto "$HOME/Downloads/YouDJNow.app" "/Applications/YouDJNow.app"
xattr -cr "/Applications/YouDJNow.app"
codesign --force --deep --sign - "/Applications/YouDJNow.app"
open "/Applications/YouDJNow.app"This removes both old app names, copies the exact working download with macOS's metadata-safe copy tool, repairs its local signature, and launches the new Applications copy. You only do this once per install.
Test the download first. If you need to confirm the downloaded app itself works before replacing Applications, use this version:
pkill -x YouDJNow 2>/dev/null || true
xattr -cr ~/Downloads/YouDJNow.app
codesign --force --deep --sign - ~/Downloads/YouDJNow.app
open ~/Downloads/YouDJNow.appOn Apple M-series Macs the codesign line is the one that actually matters — clearing quarantine alone is not enough, because Apple Silicon refuses any app carrying no signature at all.
Still showing an old version? Older installs were named YouDJNow Desktop.app. The new build installs as YouDJNow.app, so the old one stays behind and keeps opening. Drag YouDJNow Desktop.app to the Trash, then run this:
pkill -x "YouDJNow Desktop" 2>/dev/null || true
rm -rf "/Applications/YouDJNow Desktop.app"Tip: type the command with a trailing space, then drag the app from Applications into Terminal — that always fills in the exact name.
Windows builds may show a SmartScreen warning the first time; click More info → Run anyway. Not sure which Mac you have? Apple menu → About This Mac — if it says Apple M1/M2/M3/M4, pick Apple Silicon.
