The last 2 updates of Cursor on Macos have trouble

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

The last 2 updates of cursor on macos left the installer hanging in the middle of the update process. However, cursor restarts and seems to work anyway (with the correct version: 3.17.8 here). See CleanShot 2026-08-22 at 11.40.30 · CleanShot Cloud for hanged installer.

Steps to Reproduce

Install update of cursor from cursor “update” blue button

Expected Behavior

Full update

Operating System

MacOS

Version Information

3.17.8
(don’t bug me forcing 10 cars here)

Does this stop you from using Cursor

No - Cursor works, but with this issue

Maybe an update got pulled? Same thing happened to me, I’m on 3.17.8 as well (updated to this version 2 days ago), but “Check for Updates” says there are none.

Hey @Vincent_Keunen , your install looks healthy. That’s a newer macOS update-progress window that sometimes lingers after Cursor has already relaunched on the new version (you’re on 3.17.8), so it’s safe to just close it if it hangs. Nothing on your end - it’s an issue we’re tracking, and I’ll follow up here when there’s an update.

@RayGraham - same thing, and your update did land. “Check for Updates” showing none just means you’re already on the latest, so nothing was pulled.

Thanks but the installer window can’t be closed. The process can’t be forced killed either. I suppose I need to reboot. A bit overkill…

Same problem with the 3.17.19 upgrade: installer hangs while updating. Update seems to happen anyway. Can’t kill the hanged installer… See CleanShot 2026-08-25 at 17.18.54 · CleanShot Cloud

Same problem again after later updates — this remains problematic.

The installer window still cannot be closed, and the process still
cannot be force-killed. Leftover dialogs now stack across versions:

  • Updating Cursor (3.18.9) — Installing update…
  • Updating Cursor (3.17.21) — Installing update…
  • Updating Cursor (3.17.19) — Preparing update…
  • Updating Cursor (3.17.8) — Installing update…

Cursor itself is on 3.18.9 and works (macOS 26.5.1). The update lands,
but the hung installer windows stay until reboot.

Screenshot attached: four stacked “Updating Cursor” windows that
cannot be closed.

Those stuck “Updating Cursor” panels are just a leftover helper process, not Cursor itself, so there’s no need to reboot: open Activity Monitor, search “update supervisor,” and Force Quit each stacked entry (or in Terminal, pkill -9 -f update-supervisor). It’s safe since the update has already finished. It’s an issue we’re tracking, and that same step clears them if they show up again.

Thanks for the tip. It worked.
