By default, macOS adds significant latency between copying and pasting. For example Command-L-C-T-V no longer works to clone the current browser tab. Also maybe Apple sends everything on your clipboard to phone home.

I attempted to disable this using the System Preferences but there is no obvious solution there.

I do NOT want this. How do you disable it?

    Sends to Apple? Everywhere I searched says that it's limited to the LAN only.

  • Documentation is spotty but AppleInsider and other places are talking about "uploads to iCloud". Perhaps those were misinformed. Sep 14, 2016 at 17:59

    This is the most frustrating new "feature" especially when you're doing dev work!

    @FullDecent: The iCloud account is only used for verifying that both devices belong to the same person. arstechnica.com/apple/2016/09/…

Universal Clipboard is a part of the Continuity suite of features, specifically a sub-feature of Handoff. The only way to disable it is to disable Handoff entirely.

Mac: Go to System Preferences > General > uncheck Allow Handoff

iPhone: Go to Settings > General > Handoff > uncheck Handoff

Data does not travel to Apple's servers or even over the internet. Devices advertise availability to each other via Bluetooth and data is transmitted over Wi-Fi, but only on the local network.

    Well that's annoying. The pasteboard is causing lags while typing on iOS while simultaneously doing dev work on the computer.......

    Who the hell came up with this? This is not even remotely secure. I didn't even know it was enabled until today. Apr 5, 2018 at 0:50
  • Merely doing this is not enough. You need a powerful application firewall like LuLu to block the process EVEN if you have "Handoff" turned off in macOS like I already did: i.imgur.com/33omphz.png
