Any help to make the game work on macOS? I downloaded the French version.

Here is my setup:
- MacBook Pro 2016
- Intel Iris Graphics 550 1536 Mo
- macOS 10.14

When I click Play, nothing happens. When double clicking the game in the Finder, it says the app can't be opened…

Same here

Just tried to play on an iMac (late 2013 with GTX 780m running Mojave) - won't launch unfortunately. Same on my 2014 MBP with 10.14 and intel graphics. I really hope it is unrelated to the fact that Mojave doesn't 'like' 32-bit apps (and Apple announced the next version will kill support for 32-bit apps altogether).

Nothing in GOG's launch settings really suggests a change that might help with runtime.

CYAN, please help! :)

Unsurprisingly, really.

Throw the windows version at Wine or Crossover.

It seems Cyan support is reactive. In case you have any issue, you can ping them directly at support@cyan.com. They told me they were aware of the issue and that they are investigating.

That's already what the Mac version is doing.

Tried to run Myst iV Revelation both in macOS Mojave and in macOS High Sierra.
Same result as mentioned above.
Clicking the Play button in GOG Galaxy starts syncing and nothing happens, the Play button is released and can be pressed again.
Starting Myst IV Revelation from the Finder gives a message box with the text "The application “Myst IV Revelation” can’t be opened." :-(
I really hope this problem is solved quickly.

Same issue here.
OSX 10.14.1 / MacBookPro12,1

There's a script buried in the application bundle that's not executable. This will fix it:

chmod 777 /Applications/Myst\ IV\ Revelation.app/Contents/MacOS/launch_script.sh

(paste that command into Terminal.app)

That did the trick. Thanks!

Worked here too. Thanks a lot!

WOW great- worked for me too

It worked. How its still broken when its a simple permissions issue?

That's the shell script that launches the game itself. If that doesn't work, nothing works.

I had the same problem and figured it was some kind of permission issue. This post saved me time trying to figure out which file was the problem.
