What’s in the app
Everything you need to talk to your team
Chat
Direct messages, groups and channels, with files, replies and @mentions.
Voice and video calls
Call from any direct or group chat, or schedule a call and invite guests by email.
Calendar
Your RIO calendar, one click away from your chats.
Screen sharing
Share your whole screen or a single window during a call.
Screen control, with your approval
Someone in the call can ask to control your shared screen. Nothing happens until you allow it, and Esc or Stop ends it at any time.
Notifications and unread badge
Notifications for new messages and incoming calls, and an unread count on the app icon.
First time opening it
Allow RIO Connect Dev once
RIO Connect Dev isn’t signed yet, so your computer asks once before opening it. After that it opens like any other app, and it tells you when a new version is ready to download.
On Mac
- Open RIO-Connect-Dev.dmg and drag RIO Connect Dev into Applications.
- Open RIO Connect Dev from Applications. Your Mac says it can’t check the app for malicious software; choose Done or Cancel (don’t delete it).
- Open System Settings, then Privacy & Security. Under Security, choose Open Anyway next to the message about RIO Connect Dev, then confirm with Open (or Open Anyway and your Mac password).
- Sign in with your RIO account. From then on RIO Connect Dev opens like any other app.
On Windows
- If your browser says RIO-Connect-Dev-Setup.exe isn’t commonly downloaded, choose Keep (it may be under … or Show more), then Keep anyway.
- Open RIO-Connect-Dev-Setup.exe. If Windows says it protected your PC, choose More info, then Run anyway.
- Follow the installer. It installs RIO Connect Dev for you only, with no administrator password, adds it to the Start menu and can start it when you sign in.
- Sign in with your RIO account. From then on RIO Connect Dev opens like any other app.
