 ====== Why won't Zotero start up on my Mac running macOS 10.10 or earlier? =======
-Zotero requires macOS 10.11 (El Capitan) or later, as noted on the [[:system requirements]] page.
+If you start Zotero on a very old macOS version, it may fail to start, or you may receive this message:
-We haven't supported macOS versions before 10.11 (El Capitan) since 2019. macOS 10.11 was released in 2015 and can be installed on Macs released [[https://support.apple.com/kb/sp728|as far back as 2007]], including all Macs running 10.9 (Mavericks) or 10.10 (Yosemite). If you're running one of those versions, you'll need to upgrade to continue using Zotero.

+Note that most modern software, including all major web browsers, requires at least macOS 10.11, so you are likely using a web browser and other software that is no longer receiving security updates and is not safe to use on an internet-connected machine.
