Safari 13 Open in Dashboard "Missing Plug-in"

Try:

pkill Dashboard

Or:

pkill Dock && sleep 1 && pkill Dashboard

That fixed my problem, but now I put the second line in my cron jobs to fix Missing Plug-In error after reboots and to renew web clip info on my desktop automatically. It's a bit annoying when Dock restarts, but one per five minutes think it's worth patience to see important web info on my desktop.

Thanks for your attention!

I have this issue too. It's about the only thing I use Dashboard for now. I guess I can make a webpage with all those web clips on them if it doesn't get fixed. As a matter of fact, I think I'll do that right now.

I'm not upgrading to Catalina just yet but I tried Safari 13.0.3 beta and this didn't remedy the issue. It's likely the OS update that fixed it for you and I guess I'll just have to wait until I can update to Catalina

I have the same issue with 10.13.6 and Safari 13.0.3 but while using

defaults write com.apple.dashboard devmode YES

command while placing web clips from Dashboard to my desktop, unfortunately it doesn't work though the other widgets which are not web clips are working fine.

Anyone is facing the same problem?

Thanks!

I resolved this by using a time machine backup of the Web Clip widget. Searched "Widgets" back a few months and found the Widgets Folder in the System/Library. Replaced the Web Clip.wdgt file with previous version.

Since Dashboard widgets are gone in latest MacOS builds, you should take a look at the Fluid app. You can create a stand alone "app" based on a webpage. Its a great little application, and has a lot of uses (Great for streaming video websites (netflix etc.) and other web based services that would be nice as a stand alone app.)

Thank you,

I don't know why I didn't bother trying that. It's in /Library/Widgets not /System/Library though.

I'm just going to make a custom webpage instead of/or combined with Fluid when I eventually update.

I've got similar problem but in my case it happened after I rearranged my dashboard. All the other widgets kept working well but the WebClip started showing "Missing Plug-in" alert. What made a trick for me was removing corrupted preferences file (Users/[user name]/Library/Preferences/com.apple.dashboard). After moving the preferences file from Preferences folder, a new file will be created as soon as you restart. But remember - new preferences means losing your old settings - e.g. sticky notes - so before deleting the preferences file make a screenshot.

Safari dropped support for most plugins in Safari 12. Have you checked Safari/Preferences/Websites to see if the plugin is there and enabled?
