We were using the 2013 imac macOS Catalina 10.15 with Twinmotion normally, version 2022, we did the 2025.1 update and from then on the mac started to become unstable, then Twinmotion crashed, the Epic Games Launcher crashed and the entire system crashed.
The system did not let me uninstall the update and now we are without a computer because the computer’s startup disk is no longer available after several forced restarts.
