Wine for MacOS Catalina 10.15: A Major Breakthrough

After months of hard work, the team behind Wine has made significant progress in their quest to run 32-bit Windows programs on a 64-bit Mac process, making it possible to use these applications on macOS Catalina 10.15.

The challenges were many, but the team was determined to overcome them. One of the key obstacles was bridging the gap between the 32-bit interface and OpenGL that 32-bit apps would use and the 64-bit interface provided by the system's OpenGL library. Another issue was finding a way to represent the state when 64-bit code encounters an exception in a form that the 32-bit exception handling code could understand.

The team has been working tirelessly to develop a solution to these challenges, with a focus on improving OpenGL support and developing better exception handling mechanisms. The results are promising, with Steam's in-game overlay being able to run successfully, as well as other applications of increasing complexity.

In fact, the team has even managed to get Wine's built-in Notepad running, which is a significant milestone. This achievement is all the more impressive considering that Catalina doesn't support running 32-bit processes, which is what Wine has always used in the past for running 32-bit Windows programs.

The future looks bright for Wine on MacOS Catalina 10.15, with many exciting developments still to come. For now, it's clear that the team's hard work is paying off, and we can look forward to seeing even more progress in the coming months.
