Ok, some progress. Apparently I HADN'T fully removed the old Watcher software. I reran that, then rebooted. Then I installed the Switcher software off the USB device. Didn't get that error message this time. Now I am seeing the 5 bar display icon along the toolbar at the top, BUT: Hovering over it, it shows that it's in perpetual state of 'Initializing.' Checking Network Setting Prefs, no sign of it in the adaptor list, and pressing + doesn't give me an option to add a WWAN or Sierra Wireless or anything like that.

Edit: Ok, looks like I just need to select it as a Phone / Dialup. Selected Sierra Wireless / GSM from the list.

This whole process has carved through several G4 towers through 2008, shifting to a brief dalliance in the Hackintosh community in 2008 and 2009, back to native hardware with a re-cored Mac Pro (1. TRU-Install is a feature that installs the necessary drivers the first time you connect your device to your Windows or Mac computer through the micro-USB cable.

However, I don't know what to put in for the Telephone Number, Account Name and Password options. Ok, I FINALLY got it working. You have to follow the directions EXACTLY. Download their driver for Native driver use: Run that with the USB device removed. Run the Watcher Remover. Next, with the Dongle inserted, from that same package, install the other program (the switch thing.) MAKE SURE YOU REMOVE THE DONGLE BEFORE REBOOTING!!!! After reboot, insert the dongle and wait a few seconds.

I was prompted with a dialog box saying that a new Airport device was detected and did I want it to be configured? It set up all the settings and suddenly it worked! Hope this helps others. I swear, I went through similar hells when I first got this Macbook trying to get DUN working with my cell phone and Tiger, then with Leopard, then with getting the 881 working with Leopard. It's NEVER easy and NEVER standardized. Here are the steps I used to get it working without needing to use the Sierra Wireless Software: 1. Open System Preferences -> Network 2.

On the left hand list click on the Item with the Telephone icon 3. Click on the configuration drop-down, will probably be labeled 'Default', and click on 'Add Configuration.' Name it whatever you want, I'll call it AT&T 5.

Press the 'Advanced.' Button near the bottom of the window, it's to the left of the '?' Help button 6. For the Vendor select 'Sierra Wireless', For the Model Select 'GSM' Then Press 'OK' button. Click on the Checkbox that says 'Show modem status in menu bar' -- End of the One time set up -- --------------- How To Use: --------------- 1. Plug in the USB Modem stick.

Click on Telephone icon in the menubar then, Click on the AT&T menu item, 'Or whatever you called the configuration in the setup instructions above.' Click on Telephone icon again and click on Connect. NOTES: -------- I had to unplug the modem then plug back in to re-connect to the internet, Otherwise it would say 'Authentication.' Then would Disconnect. I encounter the exact same 'fatal error' when I tried to connect my AT&T Sierra Wireless USBConnect Mercury through the AT&T supplied Sierra Wireless Watcher (v. 2.2.1) after installing Snow Leopard (MacOS 10.6) on my MacBook Pro 17' (3.06 Ghz). Previously, in Leopard (MacOS 10.5) it had been working fine.

Installing the firmware update had no effect. Installing on the Windows XP side through Parallels 4.0 Desktop produced the same error - the AT&T driver acknowledged there was a connection available but did not detect a card (figure that!). What DID work on Snow Leopard was this. 1) Go into System Preferences and select the Modem connection with the telephone icon next to it. Adobe highlight text not working. 2) Click 'Advanced' in the lower right corner.

3) Under the 'Modem' tab (which is the default opening), select the following pull-down menus:Vendor: 'Sierra Wireless', Model: 'GSM'. 4) An APN setting of 'ISP.CINGULAR' and CID of '1' will automatically pop up - don't mess with it and click 'OK'. 5) Back in the Network System Preferences 'Modem' menu, simply click 'Connect' (if you select 'Show modem status in menu bar' you will be able to do this through the menu bar at the top of your screen in any application.​ The result is a MUCH faster and more reliable connection than Sierra's native control software has ever been.
