macOS 11 Big Sur compatibility

Zotero is not yet compatible with macOS Big Sur, which is currently available as a developer beta. We expect to support Big Sur by the time it launches in the fall, but you should not install a Big Sur beta in the meantime if you rely on Zotero.

We'll post here with any updates.
  • I have tried to use the new Safari Web Extensions framework ( to build a native Zotero Connector extension in macOS Big Sur. I don't know if there are any advantages to using their approach over the current system used by the Zotero team, but I think it might be worth investigating.

    However, currently, the extension as built using the steps outlined in Apple's documentation doesn't work. I used the `xcrun safari-web-extension-converter` tool to convert the Chrome extension into a Safari Web Extension, and it gave me the following errors/warnings:

    Warning: The following keys in your manifest.json are not supported by your current version of Safari. If these are critical to your extension, you should review your code to see if you need to make changes to support Safari:

    I have Big Sur running on a development machine, and I'm willing to do any testing/developement the team may need towards building the extension for Big Sur.
  • Cool! Also, those warnings don't mean the project doesn't build in XCode. It does, with no errors, but the extension does nothing in Safari. Possibly related to the `applications` and `management` manifest keys.
  • Updated to Big Sur before I saw this post. But Zotero mostly works fine in Big Sur, the only issue being that when you right click an item, the menu list is completely white, which makes the menu functions transparent and invisible (although they are still there). It would be easy to do a visual update I think.
