There is no digital signature for the Mac download version. It has not changed from the file served prior to 21 April. Exact same hash. Tried 21 April, 22 April, and 11 May.

Has no one else noticed this?

Changelog for Patch 1.8.0 (added 02 August 2019):

New to Obduction:
- UE4 upgrade to 4.21.2
- New saved game path location for Mac users - this change is being handled by the UE4 engine and not Apple's macOS (*see additional notes below). Save games and config files are now stored in: library/applicationsupport/epic/obduction
- Performance improvements
- VR Improvements:
- Ability to backstep while using VR teleport
- Index and Index Controller support added
- Windows Mixed Reality (via SteamVR) support added
- Turkish [fan] localization added

Known Issues:
- In some circumstances the game may require a restart in order to apply graphics quality settings changes. e.g. If you have ‘Low’ settings applied at launch and change them to ‘Epic’ the game will require a restart in order to apply the changes
- When using a SteamVR device (Vive, Windows Mixed Reality, etc) the first time a user enters the minecart they may find themselves facing backwards. We’ve attempted a fix for it, but it caused more problems than it solved. User should be able to turn in the minecart and face forward with no issues.

Windows Mixed Reality headsets:
- A crash can occur if the headset is unplugged, fully powered off, etc. during gameplay
- Under some conditions with certain WMR headsets, the laser pointer will not take effect on the main menu, forcing the user to point with the headset and select the menu entry with the main button on the wand. Once in game, the input will correct itself.
- Ambient occlusion differences in each eye visible in some areas:
- Under some conditions, a difference in shadows and lighting can be noticed in each eye in some VR headsets.
- Mac OS Catalina (beta) may exhibit unusually long pauses and stuttering video playback.
- *MacOS Users: Due to changes in how and where save files are written to disk, once the game has been run after receiving the update, your save files will no longer be available in an older release. Users who choose to roll back to the previous release will need to manually move the files back to the original save location. Your original save file location can differ between two locations depending on OS release and when the directory was created: ~/Library/Containers/com.cyan.obduction/Data/Library/Application Support/Epic/Obduction/Saved/SaveGames or ~/Library/Application Support/Epic/Obduction/SaveGames

Changelog (from Steam) for Patch 1.8.1 (added 12 August 2019):

Improvements made:
- Fixed issue that caused you to strafe and turn in VR Free Move mode.
- Fixed the large stone stair sphere in Hunrath. It now rotates as expected.
- Controller note: In Teleportation mode, both left and right controllers can be used for turning. In Free Move mode, only the right controller will turn.

Known issues:
- If you run into an issue where you cannot move, you need to delete your Input.ini file and run the game again. This file is located at...
Windows: %LocalAppData%\Obduction\Saved\Config\WindowsNoEditor
Mac: ~/Library/Preferences/Obduction/MacNoEditor (Use Command+G to type in the path.)

- When using smooth motion input with Windows Mixed Reality motion controls, a movement ‘drift’ can occur. We’ve found this is a common problem. If this happens, open up the SteamVR Input configuration for Obduction and add a dead zone to the left joystick “move” input.

Patch (07 November 2019)

Hey all,

We've pushed out a small update today to address the issues that were being caused by HDR. After quite a bit of discussion, looking at our options, and finding out what we could do with the small amount of time and resources we have, we've come to the conclusion that we'll have to disable support for HDR for the time being. We'll post an update with news if or when we're able to revisit this issue.

Thanks everyone.
Patch (29 November 2021)

Fixed crash on startup on some machines, like 11th gen intel machines. Very specific, we know! It has to do with an SSL library thing that Intel doesn't have pre-installed that causes issues with startup on Obduction.
