What node version are you running, from terminal?
node -v
Electron, what Daedalus is built on, should take care of any requirements but I have seen some hiccups before.
You should have >= Node: 7.9.0 If not, note some commands take a long time to complete:
- Clear force npm cache
sudo npm cache clean -f
- Install n
sudo npm install -g n
- Install latest stable version
sudo n stable
- Verify upgrade
node -v
You should reboot your machine setting the node world right once more.
Let me know your results.
