Recent Clies, such as the TJ37 and TH55, just won't sync with Macs. Oddly, older ones, such as the SJ22, SJ30, and SJ33, have no problem communicating and work right out of the box with Palm's Hot Sync and Palm Desktop programs. The only option seems to be to buy the Missing Sync, which has several marvelous features, but has given some users the fits, and, at $40, is an unfair Mac tax for something that Palm should have provided in the first place! There is, though, an alternative and easy solution! It turns out that the Palm's Hot Sync simply needs to know your Clie's Vendor and Product ID numbers! It uses them to identify what's hooked up to the USB port (cable or cradle). If you tell them that, hot synching works perfectly fine and the Palm Desktop program will reflect all your dates, addresses, to-dos, and memos just as it does with any Palm PDA. So, to get this working, we have two steps: finding the ID #s for your Clie and then entering them into Palm's approved PDA lists. I've adapted the wonderful directions at http://lensovet.byethost12.com/other/ux-ss/ 1) The simplest way to find the IDs is to Google your Clie model and hunt for the IDs. (If they are in hexadecimal, they need to be converted to regular text which is an easy task as there are many hexadecimal converters--e.g., Hex&Decimal here ). For example, for the TJ37, the Vendor ID is 1356 and the Product ID is 361. It would be great if those with other Clies could post the IDs for them here, so people wouldn't have to hunt the net for them or convert them. (If you cannot find the IDs that way, you'll need to run a program that probes a connected USB device. Such tools are in Apple's developer kit and similar tools may be available on line.) 2) To make HotSync aware of your Clie, you simply need to paste the ID #s into the 3 lists that Palm uses for hot synching. You can use the Mac's TextEdit application for the job. I would put the TextEdit icon on your dock if it's not there already (simply drag it to the dock). (Note: there's no need to bother with the Property List Editor as mentioned at the web site.) To keep this post at a reasonable length, I'll describe what to do to enter the ID #s in the next message!
