Questions & Answers

As answered by people managing MultiMac and Barrier.

What makes your product unique?

MultiMac's answer

MultiMac works seamlessly across Macs signed into different Apple IDs, different macOS versions, or restricted corporate MDM environments where Apple Universal Control refuses to connect — combining software KVM pointer/keyboard handoff, universal clipboard, and native screen sharing in a ~5 MB Universal binary.

Why should a person choose your product over its competitors?

MultiMac's answer

  • 100% Native Swift/AppKit: Zero Electron bloat, zero background CPU drain, and sub-millisecond input latency over LAN or Thunderbolt Bridge.
  • Works Across Separate Apple Accounts: Ideal for pairing a personal Mac with a work-issued MDM MacBook.
  • No Recurring Subscriptions: Includes a functional Free Forever tier and an optional $39 one-time Lifetime Pro license.

How would you describe the primary audience of your product?

MultiMac's answer

Software engineers, designers, video editors, and remote professionals who work across two or more Macs (such as a personal Mac Studio/iMac and a company-managed MacBook Pro) on the same desk.

What's the story behind your product?

MultiMac's answer

We built MultiMac at NovaSynapse because Apple Universal Control requires every Mac to share the exact same personal iCloud account — which is impossible when one of your Macs is locked down by a client or employer MDM policy.

Which are the primary technologies used for building your product?

MultiMac's answer

Native Swift, AppKit, CoreGraphics Quartz Event Taps, Network.framework (peer-to-peer local LAN & Thunderbolt networking), and end-to-end local encryption.
