Q: Does iWeb work on macOS Sierra?

iWeb is on the list :

So there's no need to use Everweb.

For my own experience, I had to stay at OS X Yosemite, because the version after the OS X Yosemite gave me too many errors on iWeb, particularly when uploading the Websites.

So my recommendation is: stay at OS X Yosemite or below to don't have errors at iWeb.

iWeb is launching on Sierra, all panels and menues are working on my mac, the domain file seems to be read correctly.

The media Browser is showing iPhoto, Aperture, iMovie '09.

Looks good.

Run it and post the report here. Maybe we can help your find what is wrong with you Mac.

I have had lots of issues with iWeb and Yosemite where the last time I opened the program up, it had lost all the pictures I had created for links with the wording which you used to be able to be enter within the various Shapes.  As a workaround I had used screen shots of a file version of my iWeb project which I opened in Safari to get the screen grabs.  Now they are all lost reporting on opening that the graphics cannot be found.  With that occurring only last week I was VERY wary of upgrading to Sierra.

So can those who are using iWeb in Sierra confirm if the problem with Shapes with text entry still continues or has it returned to functionality.  I am pleased to see Leonie says that the iWeb Domain file is reading correctly.
