Questions & Answers

As answered by people managing Barrier and MultiMac.

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.
