Thanks for the info. I had downgraded to 10.6.4, but as you note — it isn’t stable either. I’ll follow your lead and re-install 10.6.1.
And ya, their record on MacOS driver support has been far from stellar over the years.
My Space Navigator is on it’s last legs (the cable boot at the base has split and the individual wires are exposed and loose). It stopped working completely for a while, but it’s OK at the moment. I’m waiting for them to finally release a wireless SpaceMouse based on Bluetooth (instead of that stupid dongle) before I replace it.
I don’t understand what’s taken them so long — they have implemented Bluetooth on their wireless CADmouse (which works with either the dongle or Bluetooth) — but with the laptop trend towards a vastly reduced number of ports (and those mostly USB-C), they are way out-of-step with the times for the SpaceMouse.
I love their hardware, but they’re a frustrating company in some ways.
