(Entering this bug for the record).
I have been privately reported that TeX mode's Synchronize command does not work in Alpha version 9.1.2 when Skim is used a PDF viewer. This is an Alpha issue (Skim has nothing to do with it).
This is caused by a typo. In version 9.1.2, Alpha introduced a new command applescript in replacement of the old Tclapplescript extension.
The typo is in the file Alpha.app/Contents/Resources/Libraries/AlphaTcl/Tcl/SystemCode/CorePackages/fileServices.tcl on line 137.
It should be
applescriptexecute$script
instead of
applescriptexecute-- $script
