10.4: Be aware of some PowerPC - Intel migration issues Apps
I migrated my user account from my old iMac G4 to my new Intel iMac using the Migration Assistant. I booted up the new machine, but the page loading times in my browser were painfully slow. I tried everything, it seemed, until I checked the Console log and noticed errors with my Safari plug-ins. Then it hit me: maybe those plug-ins were PowerPC only, and were invoking Rosetta repeatedly to run. I removed those plug-ins and voila!, my page loading speed was quicker than ever!

[robg adds: While the Migration Assistant can be a huge timesaver when upgrading machines, I chose to migrate to my Intel Mac without its help. It's not just your browser, of course, that might be impacted. There are plug-ins for Mail, Safari, and many other programs, any of which might be PowerPC only code on your old machine. By checking each app and plug-in that I was moving over, I was able to eliminate or upgrade those that were PowerPC only. Yes, it's much more time consuming to do things this way, but I like knowing everything I've installed on a new machine will work as expected.]

Whatever the real issue was, this is an impossible explanation.

Applications running Intel native cannot load PowerPC plug-ins, it's like as if they weren't even there.
You have to force the complete application to run as PowerPC through Rosetta to load PowerPC-only plug-ins.

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.

10.4: Be aware of some PowerPC - Intel migration issues
Authored by: rgray on Jan 19, '07 09:20:48AM

When migrating clients from G4 to Intel machines, I counsel that the best approach in the long run is to copy over the home directory elements NOT INCLUDING the Library: Desktop, Documents, Music, Pictures, Movies, yes but NOT Library. The point is to rebuild in Intel/Universal as much as possible. Only as a last resort should one resort to a Rosetta solution. This was learned after too many attempts to use the Migration Assistant solution. It helps that my guys tend to be one or two computer operations and who tend to want to actually learn something about their systems.

I found the easiest way to find what PPC code I was still running after the migration was to use the Activity Monitor and you can sort by "Kind" which is either PPC or intel

Anyone know of any utilities that can search your system for PPC or Universal apps?

Yes. There's a little program called Xslimmer, which is a program to slim down your universal binary application to either PPC or intel only. It will show you the information with in seconds when you drag any application in your machine to Xslimmer. It's a mighty useful shareware program!

PowerPC - Intel not the only migration issues
Authored by: myrkr on Jan 19, '07 12:02:50PM

Binary versions are not the only migration issue. I recently migrated from one PowerPC to another, manually because i had no 6pin to 6pin firewire cable. QuickSilver and Firefox would hang trying to mount an afp volume. It turned out that there were indexes for QuickSilver pointing to the non-present volume. Firefox was trying to load an Internet pluging that was just an alias to the disconnected drive.

This didn't seem to help on my end. Browsing is still as painful as ever even after a full reinstall of 10.4. I removed the plug-ins and thought there was a slight improvement but continued surfing showed that not to be the case. This started about a week ago and I had migrated my system however everything was working fine. One day last week it just took a nosedive. Applecare could not figure it out and a "genius" fried of mine was stumped as well. At this point I am still scratching my head...

The Migration Assistant worked perfectly for my move from G4 to Core 2 Duo.

1. I had already upgraded all apps I could to Universal versions.

2. I knew to delete ~/Library/Caches/com.apple.helpui after migrating (otherwise the Help Viewer won't work properly).

I just ran into this - upgraded to a new Macbook, selected migration and it actually migrated all sorts of stuff besides my home folder, thinks like all of Fink got copied over, and several system hacks I'd put together, like anacron and a hand-carved "slip a fortune into your login dialog" script. <b>and</b> my "classic" system folder.
