10.4: Be aware of some PowerPC - Intel migration issues
Authored by: charlietuna on Jan 19, '07 08:25:29AM

I also noticed this when I migrated using the Assistant. My Apple-supplied Widgets (particularly the Flight Tracker I think) were non-functional because they had been copied from my G4 during migration. I ended up having to reinstall OS X anyway.

Widgets are cross platform by design. There is no such thing as a PPC or Intel widget.

That is incorrect. There are several widgets that I (m)

have installed that cause the translated service to startup whenever I activate dashboard. If I remove those widgets from dashboard, the translated service does not startup when I activate dashboard.

If they were not PPC only, then translated would not startup every time I activate Dashboard.

Not true. Widgets can call native code (e.g. objc). That code might be PPC only.

A ery good point; and a common problem.

The Apple Discussions board for Dashboard is filled with people who have done the same thing. Some people seem to believe that widgets are only XHTML, CSS and JavaScript and thus Universaility does not apply. However, many sophisticated widgets hava WebKit and/or Cocoa plugins and as compiled code, these can be PowerPC only.

The Dashboard server is "smart" in that it will automatically run a widget w/ PowerPC plugin in Rosetta (this is why some widgets are slower on Intel macs than on the PowerPC - the widgets haven't been made fully Universal). However, the Dashboard server assumes Apple's default widgets are Universal (as they come preinstalled, Apple includes "Universal" copies of their default widgets with Intel Macs).

As you discovered, Migration Assitant wipes out these Universal copies with PowerPC ones, and thus you get the "blue brick" in those widgets that should be loading plugins.
