Setting up iSync on 2 Computers to sync with Treo 650

Question

I have a iMac G-4 and a new iMac G-5. The first sync was done on the G-4 with HotSync using the USB connection which did find and sync the G-4's Address Book for some unknown reason, but not iCal. Now, I'm working with the G-5 and trying to set up iSync with the Treo. Using Bluetooth, the G-5 can find the Treo but I get a dialog box that says "iSync cannot connect to this device".
Could there be a conflict because the G-5 is using all the data that was transferred over from the G-4?
I would appreciate any help out there. Thanks in advance.

Welcome to Apple Discussions.
No, there is not inherent conflict, although you must understand several things:
It is a really bad idea to transport your Palm device as an effective 'storage vault' between two Macintosh computers, and synchronize with each. The correct approach is to pick one of these computers to synchronize your Palm device with, and keep the other Macintosh 'in sync' with the remainder of the pool using either .Mac Sync or MySync.

If you want to synchronize using Bluetooth, you should pick one Bluetooth-capable Macintosh to synchronize with, stick with that machine, then pair them by initiating the pairing from the Treo and confirming this pairing from your Macintosh. The first time you synchronize, you should overwrite the contents of your Palm device, so be sure that you are prepared to do so before you synchronize. If this means first synchronizing with .Mac Sync or MySync, then do that first.
If you intend to use USB instead, again pick one machine to perform your Palm synchronizations with, but it need not be a Bluetooth capable machine. If you intend not to switch machines but do want to easily switch between the faster USB path and the more convenient Bluetooth one, purchase a copy of the Missing Sync for Palm OS which facilitates this activity. Switching back and forth using iSync is problematic.
If you intend to use iSync and have added your Palm device to using the Enable Palm OS Syncing… option under the Devices menu—regardless of whether you have chose to use USB or Bluetooth—then you should be ready to proceed once you have followed the instructions which appear in the dialog boxes which appear when you select the option. [There is no other way to add a Palm device to iSync.] You must configure the actual synchronization profile before you proceed, however, by selecting the Tungsten device labeled with your HotSync name in the main window of iSync, an action which will drop down a configuration pane to enable your Contact and Calendar options.
If you intend to use the far more flexible and robust Missing Sync for Palm OS, then you must follow the instructions they provide for installing and configuring that application, again being sure that your first overwrite the contents of your handheld during the initial synchronization event.
Be sure that before you do so, in either case, that you back up your calendaring and contact information using the built-in back up options under the File menus of both iCal and the Address Book.
