I am excited to see so many happy people using this extension. From what I have seen RoundCorner looks easy to use with amazing results... So far my experience has been the opposite.

What I've read and researched so far is my issue is because I have a Mac that runs the latest Catalina OS and that my system is cap-sensitive.
My issue cannot be isolated... I am one of countless users that operate on Macs and use SketchUp professionally.

I urge @Fredo6 and/or someone with association to seriously look into this and offer a*'simple'*work around. Not everyone out there is an IT tech or a computer wizard to install back end code for an extension (Perhaps a PC or Mac extension option?).

Anyhow, perhaps I'm still missing something. I still have hope and still look forward in using this extension in the future.

Thank you for everyone who have listened and chimed in.
Your efforts were much appreciated and I'm sure I'll be reaching out again for advice on something else in the future

I suspect that since RoundCorner hasn't been updated since the end of 2018 it might not be Catalina MAC friendly, even if it's v2020 compatible ?
However, Fredo's newer tool FredoCorner is up to date v1.7d, and works much the same [and better]

Why not try that alternative ??

I just tried FedoCorner and the 'same' thing happened... It looks like it is either not updated for Mac Catalina OS and/or the case-sensitive issue. I hope the folks at @Fredo6 (if they are listening) will address this issue for all the Mac users out there

I'll try that out and report back. Thanks for the heads up

The reason nothing is happening when you try to use the tool is that there's an error - see the Ruby Console message...

Someone at sketchup.com asked if you had your MAC set up to be case-sensitive ?
I don't think you confirmed...
MACs should be case-insensitive, otherwise weird issues can happen...
Google to see issues and fixes...

I do not know how to check if my system is 'case-sensitive'. Any advice would be appreciated

(For context) Attached is a video screen grab of my issue:
When I select the Round Edge tool nothing happens; no tool bar appears/opens up.

RoundCorner_screen grab.mov

Attached is a screenshot of the Ruby Console window.

For reference. I have attached a screenshot of the downloaded/installed extensions.
• LibFredo6_9.5
• RoundCorner_3.3

So I successfully downloaded the latest ‘RoundCorner’ plugin along with the latest accompanying ‘Fredo6 LibFredo6’ plugin. I have been watching the online tutorials and the extension looks amazing and the installation process makes complete sense…
After downloading both and installing into SketchUp; I restarted SketchUp and the computer.

I created a simple rectangular box, choose the edges, (followed the video tutorial) and when I clicked on the Rounded Edge tool, the other tool bar (as shown in the video) does not appear.
Not sure what the issue is. I restarted the program and also restarted my computer again, I also deleted, and re-installed both RoundCorner and LibFredo6 … and no difference.

Tech Info:
I have a licensed SketchUp Pro 19 running on a (year-old) MacBook OS_Catalina 10.15.3

There have been posts regarding issues with Mac_Catalina... could this be the reason...?...if so, is a fix and/or update coming soon..?

Any advice would be greatly appreciated.
Thanks.
