permissions change on Mac?

Hi,
Is there any conceivable reason that an issue within Zotero itself would suddenly make it unable to open on my Macbook? I've used Zotero for years, then went to open it today and got a popup saying "You do not have permission to open the application 'Zotero.app'" along with an error message (provided at the end of this post)

Normally I would assume this was just an issue with my permissions settings in MacOS, but they are set to "Read & Write" for my user account, as well as the admin https://imgur.com/a/lHDSu6C

I tried rebooting, with no change. Any other suggestions? My next step, I suppose, is an uninstall/reinstall, but I'd rather not if there's a way around it.

  • I don't think so, but any reason you couldn't update your OS? Unless I'm seeing that incorrectly, you're on 11.5.2, which is from last summer, and Apple has released a bunch of updates (including security patches) to Big Sur since. We've definitely seen mysterious errors disappear after OS updates.
  • My next step, I suppose, is an uninstall/reinstall, but I'd rather not if there's a way around it.
    @aaronbcowan: To be clear, though, there's absolutely no downside to this — just delete Zotero from Applications and reinstall it from the download page. It takes 30 seconds. There's not usually any reason to do this, but in this case it looks like your version is corrupt somehow — due to file corruption, malware, or something else — and so that would be the first thing to try.
  • Thanks to you both. I did update MacOS, which didn't fix it - but the delete & reinstall did. I didn't realize the reinstall would be so quick - I had assumed deleting the app would delete all the storage, and then have to rebuild that once reinstalled.
