Extensions and rubies doesn't load [Mac] [solved]

[tfdesign]

I've just updated to Snow leopard (this morning), and so far I'm very impressed with the overall performance- compared with Leopard. I've also updated to the very latest SU7 build- which seems fine now. Even this website page displays properly!

What was I worrying about?

Rest assured Andrew, you'll be the first to know if anything doesn't look right.

Hi folks, this is my first post to this forum...
I am new to sketchup and just purchased a license for pro 8.
My issue is related to this topic in that I am unable to install extensions/ruby scripts.
Here is a screen shot of the error message:

My operating system is OSX 10.6.8 (snow leopard), here is a screen shot of my disc settings:

Still no banana however...

Any advice would be greatly appreciated, I am not a computer wiz but I can follow instructions!
Thanks kindly,
Orion.

@oic

You forgot to tell us what it was you were trying to install, that generated the error-message...

Only RBZ archives can be auto-installed. ZIP and RB etc must be installed manually OR use thomthom's 'Simple Plugin Installer' tool, available from the Plugins index menu item above...

Do you have full security permissions [read/write] to the SketchUp plugins folder?
If not you can't add files into it...
Try changing those...

The correct plugins folder is Macintosh HD/Library/Application Support/Google Sketchup 8/Sketchup/plugins [NOT the 'user' one]

You can run this line in the Ruby Console to double check that your installation is right:
Sketchup.find_support_file('ocean_extension.rb', 'plugins') - this .rb script is supplied with SketchUp and is [or should be!] in the correct folder...

Thanks TIG,
I had assumed that I did have read/write permissions for the plugins folder but had read only, now it works..
these things always seem so obvious when solved..
this forum just saved me from a lot more faffing around,
Cheers,

I have the same problem as oic above but I'm very new to this stuff and and have no idea how to verify if I have read and write permission? I ran : Sketchup.find_support_file('ocean_extension.rb', 'plugins') in the ruby console and yes my plugins are in the right place. I still get the same "unknown error" message when trying to load a .rb or .rbz file of any kind. I have tried many different plugins and I'm about to shoot myself in the face.
Please help soon.
Thanks

The resetting of your MAC's plugins folder's permissions to FULL Read/Write has been covered many times in the forums...
Here's a good one http://sketchucation.com/forums/viewtopic.php?p=468689#p468689
