UT v469b - can't run on Mac (Assertion Failed)

UT now belongs to the "old" Unreal as well. Supporting it for OpenGL and Sound its time to put up a board now.

UT v469b - can't run on Mac (Assertion Failed)

Post by Trydi »

Hi,

I've downloaded patch for Unreal Tournament - v469b. I didn't know about new patches / releases. It's a great news! :)

So - I've downloaded it (dmg file), installed to Applications, copied files from Windows version to /Applications/UT/Contents/MacOS.
But it's a Mac, gaming can't be so easy. And I was right...game throw some error on startup :)
Assertion failed: GetPropertiesSize()>=sizeof(UObject) [File:/Users/stijn/utpg/Core/Src/UnClass.cpp] [Line: 1200]

History: UClass::Serialize <- LoadObject <- ULinkerLoad::Preload <- ULinkerLoad::Preload <- ULinkerLoad::Preload <- ULinkerLoad::Preload <- ULinkerLoad::Preload <- ULinkerLoad::Preload <- ULinkerLoad::Preload <- ULinkerLoad::CreateExport <- IndexToObject <- ULinkerLoad<<UObject <- ULevelBase::Serialize <- ULevel::Serialize <- LoadObject <- ULinkerLoad::Preload <- PreLoadObjects <- UObject::EndLoad <- UObject::StaticLoadObject <- LoadLevel <- UGameEngine::LoadMap <- UGameEngine::Init <- InitEngine <- main
On my second attempt, I've copied necessary files to /Library/Application Support/Unreal Tournament. No luck - assertion failed.
Maybe I'm doing something wrong. Just followed instructions in readme file.

System: macOS Big Sur 11.2.3 on Intel based machine.

Are you overwriting any .u files? that looks to be the suspect to me. Seems maybe Engine.u got overridden with non-UT469 version. The error message is basically saying C++ version of the Object class doesn't match what it finds in the .u file.

Was the assertion failed message identical on both attempts?

I'm ashamed to admit it... I've copied "System" folder from Windows version. Gosh...my bad. I didn't noticed ::)
With System folder delivered by patch, everything works like a charm...

I don't believe it...Unreal Tournament, native on my Mac U_On
Sure, I've spotted some framedrops but...hell...UNREAL TOURNAMENT working native on my Mac thumbsup

Many thanks!

I did the same mistake and resolved this with the help of this email thread. Thanks!
The feeling is even more weird when game is running natively on ARM-based Mac 🥲
