Have downloaded latest update to 2014 from earlier 2014. does anyone know what the update contains?

It's ok I've solved the problem.....need to go to plugins folder, context click and allow permission to read and write.

This is message i get when i try to install sketchucation 2.6 plugin. ( i firstly download it to "downloads"...I then go to preferences/ extensions and then "install extension" ...go to downloads and locate and select rbz file..... then I get this message: " SketchUp was unable to install the Extension you have chosen for some unknown reason.

Consult your Extension's documentation for additional help."

"This is the message I get when attempting to install any plugin from extension warehouse. Same as when i try to install sketchucation rbz file. Sketchup was unable to install the extension for an unknown reason. Consider downloading the extension using your web browser and manually installing it.

Yes have tried that but get same message that i need to download and install manually. But when I try to paste file into plugins it won't allow. Is this a zip file I need to unzip first ?

I've tried several times to install sketchucation 2.6 and I get message that I should download and install manually. I also get this message for several plugins from extension warehouse. I'm running sketchup 2014 pro on a mac. ( mavericks)
