As a diehard Mac user, I just had to try and make Verizon's new 4G USB UML290 modem work with my MacBook Pro... but I only got close.
I started with the modem fresh from the Verizon store, which I presumed was not activated in any way.
Inserting it into my MBP caused a popup alert that a new network interface option was available. That was a good sign!
Unfortunately, nothing I tried could get the modem to activate or connect, so I went on to activate it in windows vista.
After I was sure the UML290 was working in Vista, I brought the modem back to my MBP, but it still would not connect.
Then, I downloaded the latest VZAM for the latest pantech modem to have Mac support: the UMW190.
Installing VZAM for the UMW190 got me closer since that version of VZAM does appear to install drivers for UML290 and will recognize it as a device, presenting the user with a "Connect" button in VZAM.
Sadly, thats as far as I got. Each attempt to connect fails. I had hoped it would at least connect to 3G... nope.
My MBP is running SL 10.6.4 and I'll try again after updating to 10.6.5 and even rolling back to 10.5
