It's just a bug, most likely they won't fix it, you need to buy more Repentance

[schaefferjosh]

Unfortunately a system update by apple is not allowing BOI to launch correctly. It has been this way for months with 0 support from the devs. They have not communicated that its even going to get fixed.

Idk why my answer wasn't pinned* but you just need to delete the steam common files, and maybe delete the isaac game files in documents under mygames or whatever the mac alternative is. The reason is likely because mods fail to uninstall correctly leaving a null value or some such. then just reinstall.

[Z0MBE]

actaully this could be related to your mac not being compatible with the game ?? which I've never heard of

"✅ 1. Rosetta incompatibility or crash

Since the game is being run via Rosetta, and it crashes very early, this might be a case of:

The game not being fully compatible with Rosetta,

A bug in how the game uses certain x86 instructions,

Or an error during translation or memory allocation.

✅ 2. Corrupted or missing dynamic libraries

The fact that it crashed during dyld operations (dynamic linking/initialization) suggests a corrupted or missing shared library (.dylib).

steamloader.dylib might be involved, meaning Steam’s loader failed to inject or initialize properly.

✅ 3. Faulty game installation or update

A corrupted game install or recent update could cause this, especially if files were altered or compiled improperly for your architecture."

I would ask chatgpt honestly it explains error reports pretty well..

This was happening to me when I previously installed macOS Sequoia 15.5. However, the game now works when running macOS Tahoe 26 Developer Beta 5

I think I figured out a solution to it that does not require updating the operating system. https://steamcommunity.com/app/250900/discussions/0/567039356649500005/
