Mac: The Application NT4.app Cannot be opened

[Alias Pseudonym]

STEAM OS Error 4294956486
Failed to Start Process for Nite Team 4

All was working well on my Mac & Pc and now I am getting the above on my Mac when launching both from within steam and out. Reboot, no luck. Reinstalled game, no luck.

Hey, a player on our Discord server was able to resolve this by reinstalling Steam itself. Could you go ahead and try that and let us know if it works?
Recent Catalina update has had issues with the game. The devs are looking into making it work.

I'll give it a shot. FWIW, I had not upgraded to Catalina yet.

Upgraded to Catalina and reinstalled steam. That worked. Thanks!

I ran into this issue well after I upgraded to Catalina. I got it working on my machine.

To the devs:

DOESN'T FIX ISSUE
* Uninstalling and reinstalling just from steam library
* Reinstalling steam (keeping only ~/Library/Application Support/steam/steamapps folder). This is recommended if you don't want to redownload all apps (https://support.steampowered.com/kb_article.php?ref=3329-WUJN-5636)

FIXES ISSUE
1) Uninstall NITE Team 4 from steam library
2) Delete ~/Library/Application Support/steam/steamapps/common/NITE Team 4
3) Reinstall from steam library

Is there a hidden file that's left behind?

That is so weird, the last patch should have fix it. It did for me, is there anyone else on Cataline who can confirm this is the case?

PS: Thanks for the detailed feedbacks!!!

I had the same problem under catalina. I can conform that the solution works. I just followed the steps under Fixes issue.

I can confirm that I had this same issue on the latest version of Catalina (10.15.1) and NITE Team 4. The fix listed by Knorst worked:

Here is all I tried that did not work before that fix:

• Ensure NITE Team 4 was up to date
  
• Ensure Steam was up to date
  
• Ensure Mac was up to date
  
• Confirmed no programs interfering
  
• Confirmed other Steam games ran successfully
  
• Verified game files for NITE Team 4
  
• Restarted computer
  
• Cleared Steam cache and restarted Steam
  
• Uninstalled and reinstalled NITE Team 4

Again the above fix did work but the patch for the game itself did not resolve the issue. Please let me know if you have any other questions about this.

This is a Steam/Mac issue that arbitrarily gets caused (and resolved by) game updates. If you Google the error, you can see it's happened to all sorts of games for years. These are things that have both worked and not worked for many players (including a mac user at our office):

- Uninstalling / reinstalling the game
- Uninstalling / reinstalling Steam (this is what worked for my coworker)
- Installing a new patch
- Switching to a different branch

Hopefully yesterday's patch resolved it. In case it didn't, I just published a new public branch called v1.2.0a which is the previous build. All that's missing is a couple minor bug fixes. Try switching to that one (and maybe back again), that might fix the issue.

Thanks! and sorry for the inconvenience.
