Mac OS X Update (PowerPC) 10.4.5 and SyncServices

Question

According to documentation which shipped with Mac OS X Update (PowerPC) 10.4.5, SyncServices applications and frameworks were not updated in this latest release. Therefore, there should be no adverse impact on iSync, .Mac Sync or applications like the Missing Sync for Palm OS, MySync or other applications which use the SyncServices framework. No issues have arisen in my configuration.
There is evidence of some impact on calendaring and task data in iCal, and possibly on other applications which are time-zone dependent, as time zone and Daylight Saving values have been updated for some areas to reflect changes for 2006 and 2007. There has also been a change made to address an issue with synchronization to iDisk volumes larger than 4 gigabytes.
Before installing this update, I recommend that you back up contact, calendaring and task data using the respective options in the Address Book and iCal, and backup your critical files using Backup to .Mac, local volumes or removeable media.
There is no evidence that support has been added for additional mobile handsets, so those waiting for such extensions will have to wait a while longer.

Hi Melime, and a warm welcome to the forums!
"Try Disk Utility
1. Insert the Mac OS X Install disc that came with your computer, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
*Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
3. Click the First Aid tab.
4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
5. Select your Mac OS X volume.
6. Click Repair. Disk Utility checks and repairs the disk."

Then Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot.
The usual reason why updates fail or mess things up, is if Permissions are not fixed before & after every update, with a reboot... you may get a partial update when the installer finds it doesn't have Permissions to change one obscure little part of the OS, leaving you with a mix of OS versions.
Some people get away without Repairing Permissions for years, some for only days.
If Permissions are wrong before applying an update, you could get mixed OS versions, if Directory is the slightest messed up, who knows!
If many Permission are repaired, or any Directory errors are found, you may need to re-apply some the latest/biggest updates.
