The only three "PowerPC" that I see are "Microsoft Query," "Open XML for Charts" and "Open XML for Excel" that must come from the Office 2008 Install. As far as I know, I have never "used" these.
If you were to use them, you'd notice a slight lag on first use since Rosetta would have to load first. After that, you really won't be able to tell the difference in speed between native Intel and translated code. Not on smaller apps anyway. You can definitely tell the difference if you have something like Photoshop CS4 set to run in Rosetta rather than native Intel.
The files for Rosetta installed by OS X are here:
/private/var/db/receipts/com.apple.pkg.Rosetta.bom
/private/var/db/receipts/com.apple.pkg.Rosetta.plist
/private/var/db/dyld/dyld
shared_cacherosetta
/private/var/db/dyld/dyld
shared_cacherosetta.map
/usr/libexec/oah/RosettaNonGrata
/private/var/db/RosettaVersion.plist
/usr/libexec/oah/translate
They take up all of 200 MB of space total.
I am wondering if we see a "new" version of the 10.6.7 updater or just an small update file to correct this problem, or both?
Couldn't say. My
guess would be a replacement of 10.6.7. Apple's done that before where they pulled an update and gave the corrected file the same number. Doing a get info on the new file showed the name as (example) 10.6.3a.
