Designer Software on new SIERRA OS for MAC

We have confirmed an issue reported about Apple’s new operating system “macOS Sierra”.
We are currently working on a resolution so please wait to upgrade.

There is a workaround for those who have already upgraded.

See more information here: http://support.carvewright.com/mac-os-x-sierra/

Is this going to fix the issues with yosemite if we wait and upgrade both?

I don't know.

Is there a workaround to be able to import an STL file?
When can we expect a fix for this issue?
