Black Screen on Mac Big Sur ( 11)

[ckko]

On MacOs Catalina, i was able to play the game without any problems, but as soon as i upgraded to MacOs 11, the game opens, i can hear the sounds however the screen is just black. Does anybody have the same problem?

Just bought the game and same as the subject here.. black screen.. thought it was my MAC problem but seems it was the update.. please patch it Steam Team..

This issue really pissed me off! I am certain there must be a patch/workaround. So far, googling has given me nothing - but I do have some error logs. I went into the package contents of the RCT Classic app that steam installs (in my case in Library/ApplicationSupport/), and ran "./RCT\ Classic" from the terminal.
As I suspected, it looks like it could be OpenGL issue.... Apple has slowly but surely stripping OpenGL support out of MacOS (to unify their OSes - OpenGL isn't very iOS friendly...)
Here's my log, where I get to start seeing the black screen - after the GL ERROR line, that repeats until I kill the app (ctrl+c):

/RCT Classic.app/Contents/MacOS % ./RCT\ Classic

Big Sur, M1 Macbooks and Cataline doesn't support 32 bit games. Because of that, you're getting black screen. You can download PlayOnMac software, and open it. But in this way, there is no text in some areas in the game.

That isn't the reason, if it was a 32bit issue it wouldn't even launch.

I seem to be having the same issue. Is there a way to resolve it? A patch, mod, or somewhere i can smack my mac for it to load? If not can I get a refund or a coupon for another game that actually works?

Hi all, Unfortunately I think this game is only going to run on 10.15 or earlier. For clarity for others its running great on OS 10.13 on a 2010 imac, but not on 2013 macbook pro. It sucks but you could always grab an old cheap mac off eBay if you are keen to play a lot of this era stuff :) - or look at software workarounds or re-rolling OS

For all those with no hope in the thread, I suggest running a virtual environment or using a Windows wrapper. It sucks I miss my parks.

What is a Windows Wrapper? I'm not very tech savvy so unsure if it'd be doable for me anyway.
