I think root has more access than admin but I'm not sure.

In the meantime the problem is solved, though the mystery remains. I used Super Duper to copy a cloned backup of my old computer over to the new one and all seems normal.

Thanks for all the suggestions and help.

Hello,

I am on OSX 10.8.4.

Sketchup was installed as admin. There are only default plugins in the plugins folder, no old sketchup.rb file. I only use Sketchup as Admin. All works fine on the older MacBook with same OS version.

There is no Ruby Console menu item or any other menu item showing between Hide Dialogs and Bring All to Front in the Windows menu so I can't try the Ruby command.

It does seem like a permissions issue. I have another piece of 3rd party software that crashes on launch on the new computer and gave a permissions related error when trying to activate it. I have repaired permissions a few times with Disk Utility and Techtool Pro. Full read/write for me and admin from Applications folder down to Tools folder where sketchup.rb file is.

This is also happening after doing a clean install of the system with a new account. I install Sketchup Make and no additional plugins. The only plugins are the default ones in the newly created plugins directory. I can open the package contents for Sketchup and find the sketchup.rb file.

Hello,

I have been using the new Sketchup 2013 on my old computer and most plugins loaded fine. I migrated to a new computer and now none will load. It says "no such file to load -- sketchup.rb" for every plugin installed. I moved my complete plugins folder to the desktop, uninstalled Sketchup and reinstalled it. I get the same message when I start Sketchup with only the default plugins in the plugins folder. When I use preferences to install extensions, all plugin files are greyed out.

I have done a clean install and reinstalled Sketchup Make. Same problem.

Any suggestions would be appreciated.

thanks,
Jeff
