How to install Zotero extension in Safari on Mac mini with Tahoe?
Zotero 9 and 10 Beta fail to install Extension in Safari 26 on Tahoe OS Mac Mini A4 Pro 2024
I have recently switched from using Chrome to Safari for my research and writing. A key tool in my workflow is using Zotero to manage citations, referencing, webpage shots and so on.
For countless years the Zotero extension on Chrome has worked near flawlessly for me.
I have successfully installed the Zotero extension on my MacBook Air 2019 Intel. I do recall having to conduct some gymnastics such as deleting the Zotero app, and re-installing the latest Zotero version to force the extension to be recognized and available in Safari.
However, I've spent 4 hours today NOT able to install the Zotero Extension for Safari on my modern Apple Mini Mac Pro.
I have followed advice from Google AI and the Zotero Forums, detailed below
According to those sources the intermittent failure to install the Zotero extension is a longstanding, 'known bug' which the Zotero developers attribute to Apple.
I wish Apple would urgently work with Zotero to address the issue. I'm sure it's relevant to many students and researchers.
In summary, perhaps here's a clue to a solution. Google AI reports "Why this happens on M4/Tahoe: Apple's "App Extension" architecture requires a perfect match between the app's signature and Safari's security policy. On newer chips/OS versions, even a minor cache error prevents the "Zotero Connector" from appearing in the list, even if the file is present. "
This is my system:
Mac mini Pro 2024
Chip Apple M4 Pro
Memory 48 GB
macOS Tahoe 26.3
Safari 26.3
Below is the advice from Zotero to attempt to get the Extension Install to function. I have repeated several versions of this approach. I have tried reinstalling both the current Zotero version 9, and beta Version 10.
I have deleted the Zotero app, restarted the MiniMac, then redownloaded and reinstalled Zotero.
This is the guidance from Zotero
Zotero Connector and Safari
https://www.zotero.org/support/kb/zotero_connector_and_safari
See subsection: Extension not showing up? Save button missing or flickering?
I have completed Fix 1, Fix 2, Fix 3 in various combination, both with Zotero 9 (current version) and Version 10 beta. I have restarted the computer between deleting and restoring the app.
Using some Google AI, and Terminal Mode I confirmed the extension was ready and waiting for install.
This is Zotero's community discussion, with the response from their technical expert, dstillman

You'll see a lot of frustration reported eg
'This has been driving me insane.'
None of the workarounds proposed have worked for me.
Google AI says possibly a problem caused by my having a late model, high performance machine! What a bother!

Mac Terminal Response:
1. Terminal response =: << grep Zotero org.zotero.zotero.SafariExtension(5.0.199)A0B55346-4426-4CE1-808E-EA2CEA64781E2026-05-18 07:16:00 +0000/Applications/Zotero.app/Contents/PlugIns/ZoteroSafariExtension.appexbash-3.2$ >>
"The Terminal response confirms your Mac physically sees the extension file within the Zotero app. Since you are on a high-spec M4 Pro Mac mini running macOS Tahoe (a future or beta release), the issue is likely a strict security handshake failure between Safari and the local app bundle."
