Error when attempting to install Zotero for Mac
When I download the .dmg for Mac and double click or ctrl-click, whether from the downloads folder or after dragging to the applications menu, I get the following message:
"Zotero-5.0.96.2.dmg" is damaged and can't be opened. You should move it to the trash.
I'm running an olddd version of iOS, Mojave 10.14.6. I'd prefer not to update, so if there are any things I can try before then, I would super appreciate it!
Thanks!

I also tried Zotero 4.0; no dice.
Try downloading 5.0 using a different browser, or if that doesn't help, from a different network.
Don't use 4.0. 5.0 should run fine on Mojave.
I tried it (originally) on Chrome, and again on Safari on your suggestion. Still nothing there.
I have downloaded it from eduroam (ostensibly decent university blanket network), a visitor network (maybe same tubes), and finally using my phone as a hotspot; once each on Safari and Chrome.
Beginning to suspect there's some security setting deep in the bowels of this laptop I need to fiddle with.
But just to poke around slightly, if you open Terminal via Spotlight, type
md5sum
(with a space at the end), drag in the .dmg to paste the path, and then press Return, what does it show?If you type
hdiutil attach
(again with a space at the end) and then drag in the .dmg and press Return, what does that show?md5sum didn't do anything, unfortunately.
I did the hdiutil attach, and it opened the .dmg and plopped it into my app folder, but I was still getting the same error.
I poked around in my security settings, and Apple has oh so protectively disabled my ability to install anything not from their app store. Switched that setting to find out that it kept switching back to the restricting one, and nearly lost my academic aplomb.
FINALLY, my partner had me brute-force it w/ sudo spctl --master-disable and... LO AND BEHOLD, I got me some sweet sweet Zotero action on this 9-year-old MBAir!
It's not the *worst* way I've avoided actually working on my research, but any excuse will do.
THANK YOU, dstillman! I very much appreciate your help in getting me where all problems with Apple OS go to die: Terminal.
Disabling Gatekeeper was the nuclear option, yes, but once Zotero got in, I put in an exception in GK for Zotero and turned it back on, then confirmed that GK was still being as sulkily unwelcoming as before.
No idea what the Magically Resetting app-store-only setting problem is, but since I can't find anyone having posted or reported the same issue yet, I'm reasonably happy with how it turned out until I can solve that problem.
