This is the greatest news for me in a long time!. Geert Bevin has just updated GECO to 2.0 and it works with the new Ultraleap Gemini v5 software on Mac now!
I have the original Leap Motion Controller and it works superbly.
P.S. I’m not affiliated with anyone. Just enthusiasitc! 
mod note: Ive updated title, as I think its an interesting broader topic (than just Mac and old leap motion)
indeed, this is all good news for Leap Motion users both old and new !
(recap for those that haven’t seen the ‘news’)
Leap Motion (company) has released latest (v5) driver/software for all major platforms including apple silicon, and it covers both the old leap motion and their newer ‘ultra leap’. … on the back of that, Geert has updated GECO to support thew new driver/app.
very cool, as I frankly I thought the old leap motion was basically ‘dead’ tech these days (particularly on more apple hardware).
so great work from both Leap Motion and Geert !
So questions for me are :
will I get it dust it off? find it in the loft? or did I throw it out?
its funny, whilst I thought leap motion was pretty fun (I used it a bit with Geco 1.x) way back… I never really found it very useful… just a gimmick.
I think mainly due to ergonomics…
holding your hands in the air is just not that comfortable, particularly if you are sitting down.
also frankly, the tracking on the OG Leap Motion was a bit finicky, not bad… just you had to mindful of it in use. I have to assume the Ultra Leap would be (much) better.
on the flip side, I recently got into VR with a Sony PSVR2, and have to say, I feel the vr tech has definitely got to a new level - to a point Im getting into this tech.
and of course, Apple Vision Pro, will be another new level again, but out of my $ range for a while
though I think for now, Im more interested in the Quest 3…
why? its certainly far from the vr best tech BUT its standalone capability and its price point … and so market size, is undeniable (within the confines of how niche VR is)
but coming back to leap motion…
this foray into VR has made me believe a bit more in leap motion (and hand tracking generally), and also have ideas on how I might overcome some of the limitations that I felt in the past.
… so perhaps I will dust off the leap motion
eheh I never lost track of mine 
but yeah, stayed behind with old MBP. Definitely moving to newer setups - maybe building on the past, use the simple of gestures…
eheh I never lost track of mine
just found mine, was very dusty, at the back of a cupboard
fortunately, Id left the cables connected to it… so its all ready to go.
maybe building on the past, use the simple of gestures…
indeed, I think for me, the difference is … VR/AR/XR is a little less niche than it was when the Leap came out… or, at least, I have a little more excitement in this area, and so perhaps some more ideas in this area.
anyway… I think this time around for the Leap Motion… I’ll think about use-cases before I bother installing anything. i.e. have a use for it, rather than try to find a use for it.
btw: does anyone know if the Ultraleap software will work on a modern rPI or similar SoC?
it be kind of nice to setup the Leap Motion as a standalone piece of hardware, that just chucks out midi, rather than having to install/connect it to my Mac.
