How to screen share on Mac from another Mac: Personal vs business guide

Screen sharing on a Mac is incredibly simple for personal use. Whether you’re helping a friend troubleshoot or showing a colleague a quick demo, built-in features like Screen Sharing, FaceTime, or even iMessage can get the job done.

But things start to look different when you’re an IT admin managing dozens (or hundreds) of Macs across different locations. What if you’re supporting a hybrid team? Or resolving a critical issue on a sales executive’s Mac in a different time zone? That’s where native tools fall short.

Personal screen sharing options weren’t designed to scale for enterprise environments. They lack the management, security, and reliability businesses need. 

Then, how can the problem be solved in an enterprise environment?

How to screen share on Mac from another Mac — Native methods

Apple offers a few ways to share a Mac screen with another Mac. These work well in personal or one-off scenarios:

1. Screen sharing app (Built-in) – Available via Spotlight or System Settings, this allows users to connect using an IP address or Apple ID. It’s simple but requires manual setup and permission from the user.

Note: Make sure the Mac you want to access has Screen Sharing turned on in System Settings. See Turn Mac screen sharing on or off.

2. FaceTime screen sharing – macOS Monterey and later support screen sharing over FaceTime. It’s intuitive for quick personal sessions but lacks admin-level controls or session history.

3. Apple Remote Desktop (Paid) – Apple’s Remote Desktop is a more powerful tool aimed at IT professionals. However, it comes with limitations—it only works within the same network (without VPN tunneling) and lacks deeper integration for full device management.

These methods, while useful, don’t scale well in business settings. That brings us to the bigger picture.

Why businesses need an enterprise-grade solution

Here’s why native tools fall short in a business setting:

No centralized management

Each screen sharing session has to be initiated manually by the end-user with built-in options. There’s no single place for IT admins to view or manage ongoing sessions. This makes it hard to support multiple devices efficiently or respond quickly when issues arise.

Lack of security policies

There’s no way to define who can access which devices, set approval rules, or restrict screen sharing based on roles or locations. This opens up the risk of unauthorized access and makes it difficult to maintain consistent security standards across teams.

No audit logs or session recordings

If a device was accessed remotely, there’s no record of what happened during the session. For IT compliance and troubleshooting, logs and recordings are essential. Native tools don’t offer this, leaving gaps in visibility and accountability.

No integration with device management

Screen sharing in isolation doesn’t help when you’re also handling device updates, app deployments, or policy enforcement. Native features can’t integrate with larger IT workflows, so admins end up juggling multiple tools and losing valuable time.

This is where a UEM solution like Scalefusion becomes essential. It’s not just about screen sharing, it’s about managing remote access with full visibility, control, and security across every Mac device your organization uses.

Screen sharing with Scalefusion Remote Cast & Control

Scalefusion’s Remote Cast and Control feature is a powerful tool that enables IT admins to remotely troubleshoot and guide users on managed Mac devices through secure screen-sharing capabilities. Here’s what it brings to the table:

• Real-time screen sharing: Mirrors the active Mac screen to the Scalefusion dashboard, allowing IT admins to view exactly what the end-user sees, in real time.
• Remote Access: Provides full remote access to the admin. They can navigate the device, launch apps, perform checks, and guide users seamlessly.
• Session recording: Admins can start or auto-enable session recording for audit trails or compliance purposes. Recordings are downloaded post-session for later review.
• Multi-action support during a session:
  • Screenshot capture
  • Full-screen view
  • Reboot or lock the device remotely
  • Device info access
  • Start/stop sessions easily
• Keyboard shortcuts & clipboard access: Admins can use macOS-style shortcuts for actions like copy-paste, undo, switching apps, and more — plus clipboard sync to send/receive text between devices.
• Multi-monitor navigation: Seamless switching between multiple screens connected to a Mac during a session.
• File syncing: Upload, download, or delete files on the remote Mac directly from the dashboard.
• ITSM integration: Raise service desk tickets directly from the Remote Cast session screen if integrated with an ITSM tool.
• User consent & privacy controls:
  • Option to prompt users for session consent before casting starts.
  • Configurable settings to restrict or allow users to stop a session.
  • Auto-record sessions for privacy-sensitive use cases (like healthcare or education).
• Session alerts for admins: Notifies if another admin is already running a session on the device, preventing accidental overlaps.
• Switch user during session: Supports fast user switching on the Mac, allowing admins to switch between user accounts without interrupting the session.

The app will be installed on selected devices in a few minutes.

Step 2: Launch the app & authenticate the device

• On the Mac device, open the Remote Support app once it’s installed.

Step 4: Start a Remote Cast session

• On the Dashboard, go to Remote Support > Remote Cast & Control.
• Find the target Mac device and click Start Session.
• A checkmark in the Remote Control column means that remote control is supported; a cross mark means it is not.

Step 5: Alternative way to start

• Navigate to the device’s Details Page on the dashboard.
• On the Device Information card, click the Remote Cast icon (just before the Gear icon) to begin.

Step 6: Use the session tools

• You’ll see the Cast Console with the live mirrored screen.
• Check Session Details for device name and model.
• Use the following features as needed:
  • Create ticket (requires ITSM integration)

Once active, the Mac wallpaper turns grey and all other apps are minimized.

Final thoughts: Which method should you use?

If you’re helping your cousin fix their printer or walking a friend through Mac settings, native screen-sharing tools are more than enough.

But if you’re running an IT helpdesk, supporting hybrid teams, or managing devices in bulk, Scalefusion Remote Cast & Control is the smarter choice.

It removes the friction of manual setups, elevates security, and gives your team total visibility into Mac screen sharing sessions.

Bottom line?
For businesses, screen sharing isn’t just about seeing a screen—it’s about easing the experience. And Scalefusion Mac management solution gives you exactly that.
