SketchUp 2017 Update - 17.2.2554 (Mac 64-bit) - PowerPC applications are no longer supported

Thank you, Marc. Rebuilding Launch Services did the trick. Everything is back up and running now.

I had followed this LINK from the Troubleshooting Page, but it didn’t mention the Launch Services issue. I had also searched the forums here, but figured that it was an issue with the recent update so I didn’t get back far enough to find the thread you linked. I was figuring more that the wrong file got thrown in the DMG.
