Zotero 5.0.90 for Mac is available now with the above-mentioned fixes for Big Sur. As noted above, there are still some cosmetic issues, and we (and Apple) still recommend against installing the Big Sur beta on a production machine.

No issues so far in public beta 6 for me.

We have a fix for the broken full-screen button coming soon.

I'll see if I can reproduce the external-monitor issue.

Awesome work. So cool to have this prioritized for a smooth transition. I know I (and I'm sure many others) appreciate the hard work. Thank you.

Hi guys. I still have the external monitor issue, even though I'm not entirely sure it's the same manifestation thereof as it was supposedly fixed…

So, my setup is a Hi-DPI built-in monitor (I'm using a 5K iMac) and an old-school 1080p 24'' Philips 237E4LH monitor, and whenever I move Zotero from the main iMac screen to the external one, the window and chrome itself will be the right size, but the UI contents will be pushed to the former's lower quarter, at half the with and height in pixels.

I can get away with expanding Zotero to fullscreen on the secondary screen and back again to a floating window (which is absolutely necessary, as otherwise the plugin's reference input dialog won't show up when working in Word), because it will indeed look and work mostly right, but then I get the opposite issue if I drag the window back to the main screen (again, the size will be just right, but its contents are blown to twice the width and height and, thus, become cropped).

Now, that option would be workable, if a bug I was already soldiering through when using Catalina hadn't become much worse. When right-clicking on any item in my library (an action I perform *a lot*, as I have my library stored on my unlimited student Google Drive and syncing through ZotFile and, thus, have to rename any new item I add to ensure that process), sometimes I'd get a proper, non-retina contextual menu, but sometimes (alternately?) the menu would be the right size but be populated with tiny text. Now, in Big Sur, that only works the first time you open a contextual menu; from then on and until you quit and reopen the application, contextual menus will appear in in the wrong (integrated) screen, populated at a minuscule scale that I assume is just regular @1x text rendered in @2x Retina.

I'm utterly convinced this has to do with the entire regular vs. Hi-DPI screen discrepancy; almost all apps I have gracefully transition from one mode to the other the very moment my mouse cursor crosses that gap across monitors, while Zotero now seems seriously broken in that regard (interestingly, before said crossing and definitive mode switching, the main Zotero window does look like it will render correctly as per its pre-switch downsampled preview, except it doesn't). In any case, if you want my to do a video demonstration of this bug, please let me know.

Oh, sorry, you're right, I misread that part, I must be tired or something.

I can certainly use Zotero and do my ZotFile renaming operations (now I'm doing it using the keyboard after opening the contextual menus because they're all over the place – especially the sub-menus – and clicking them would be an absolute chore), no biggie, but I'm eagerly awaiting for an update. Thanks!

Quick update: I only realized this today, but I don't need to take Zotero to fullscreen and back, a simple manual resize (which doesn't even have to wait for the operation to be finished, I can just drag down some pixels from the top edge of the window and back up again in a single operation) or a zoom out and zoom in (by clicking the green button with Option pressed) will do the trick, either on the built-in Retina screen or on the external, low-DPI one.

@DutchJurismUser: Those things have already been fixed in Zotero.

Most changes probably are, but this required an update to the underlying framework to fix the OS compatibility problems — not sure if @fbennett was aware of that.

@michaeledwardmarks yes, the same like on my iMac.

(Just to clarify for others, @emilianoeheyns is addressing @DutchJurismUser — Juris-M won't have a fix for the external monitor issue before Zotero does.)

@ehutchins: Can you take a screenshot that shows what you're describing, upload it somewhere (e.g., Dropbox), and provide a link here? We'd also want to see a Report ID.

Update: I reinstalled the Zotero app and everything worked perfectly. All my data was intact and functionality is outstanding.

Is the Zotero standalone application compatible with MacOS Big Sur? If not, is it likely to be in the foreseeable future?
