teleport VS synergy-core

Teleport is like Barrier/Synergy, but only works on Mac. The advantage is that it supports a lot of mac-specific features that Barrier doesn't, like trackpad gestures and rich clipboard syncing.

Have you tried this?

teleport (great, free)

Apple calls this "Universal Control" and it works with iPad and some selected Macs. Solutions like this have been available forever on Macs (not iPads) and still are valuable if you use an older Mac. Free ones are eg teleport and barrier. There are many more.

Synergy is cross-platform, but not free and a "company" I despise. teleport is small and easy to use, Share Mouse works, but won't let you log in (IIRC), barrier is a Synergy look-alike, free and quite usable.

Same, Synergy for macOS / Windows / Linux connectivity. I use teleport for macOS to macOS. Teleport supports touchpad gestures perfectly unlike Synergy.

I’m not sure how well it works but there used to be some software called teleport for Mac that would move the mouse/keyboard to the other computer when you moved off the screen. Like a software KVM switch. https://github.com/johndbritton/teleport

If you want it between 2 Macs, just use Teleport. It clearly inspired a lot of the Universal Control features and supports everything like trackpad gestures, cross-device drag & drop, etc.

For those who can’t wait for this feature to be released, I’d recommend the excellent Teleport as a free alternative to Synergy. It’s limited to Mac only, but it’s great at what it does. https://github.com/johndbritton/teleport

No one has mentioned ShareMouse yet? (https://www.sharemouse.com/) In my experience it has worked way better than Synergy. I switched after getting fed up with the synergy developers not responding to various multi-year old bugs that made the software unworkable for me (e.g. https://github.com/symless/synergy-core/issues/5992).

The only downside is that you have to "renew maintenance" to continue receiving updates to ShareMouse after a year. But I haven't done that yet and it still works fine for me.

I want to be able to do things like Synergy, Steam Link, Unified Remote, and Media Servers between any of these devices, with as little added latency as possible (especially important for steam link)

i've got several fedora linux machines running and sharing their monitors via synergy (https://symless.com/synergy) , all controlled by the keyboard/mouse on the primary synergy server.

Not sure if this is what you're asking, but I've been using Synergy Pro (Windows, macOS, Linux) for years, and it works seamlessly. It lets you share your mouse and keyboard across multiple systems (with or w/o encryption), copy and paste between computers, etc.

I've got an M2 MacBook Air

Per the Advanced... screen under Displays in System Settings, you can link to a Mac or iPad to control it a la Synergy[0]

I have not done it myself, but I do not see why you could not do it with a current-gen Mac Mini

I previously used a software solution to do the same thing and it was actually really good, better even. It might have been this software but I have to check to be sure - https://symless.com/synergy - as I’m not at my laptop right now.
