In the last month we've continued to make steady progress in our quest to run 32-bit Windows programs in a 64-bit Mac process, so they can work on macOS Catalina (10.15). Ansi mc 96.1 standard. As previously described in an earlier blog post , Catalina doesn't support running 32-bit processes, which is what we've always used in the past for running 32-bit Windows programs.
Wine Stable Catalina Download
In our last post, we reported that we had gotten Wine's built-in Notepad running. That was a nice milestone, but it's a very simple app. Since then, we've gotten more apps to run, including some third-party apps of increasing complexity. The highlights are:
WineBottler packages Windows-based programs snugly into OS X app-bundles. No need to install emulators or operating systems - WineBottler uses the great open-source tool Wine to run the binaries on your Mac.

- Note that Wine does not work well with macOS 10.15 Catalina. Apple removed 32-bit support in Catalina, which is a critical part of the macOS system that almost all of Wine relies on. You can run 64-bit applications through Wine on Catalina, but very few applications for Windows are 64-bit.

- Wine Alternatives. Wine is described as 'free, open source application for running Windows software on operating systems that are normally not supported. With Wine, you can install and run these applications just like you would in Windows' and is one of the leading apps in the OS & Utilities category.
* Notepad++
* Some simple OpenGL test applications
and, just today:
* Steam!
Wine Download For Mac Os Catalina Download
* and, via Steam, Plants vs. Zombies
Not only did Steam run PvZ, but it downloaded it and installed it from scratch.
Steam also did launch Team Fortress 2, which played the Valve logo video and then showed the Loading screen. But it got stuck there. Oh, well, still work to do!

But it's really encouraging to finally see some real stuff working!
Technical Notes
By: Ken Thomases
In order to get this far, we've had to overcome challenges in a few areas.
The greatest amount of work has been in 'exception handling'. An exception is an event that may require a special response from the program. Often, an exception arises due to an error or misbehavior of a program, such as attempting to access memory that's off limits. Sometimes, though, some programs use exceptions to control flow of execution through their code.
Either way, it can be tricky for us because our 32-on-64-bit Wine is running both 32-bit and 64-bit code. The exception handling code of a 32-bit app, though, can only understand the state of the 32-bit code. We needed to find a way to represent the state when 64-bit code encounters an exception in a form that the 32-bit exception handling could, well, handle.
The next biggest area of improvement has been OpenGL support. OpenGL is currently the main library Wine uses to render 3-D graphics. It's what Wine's implementation of the Direct3D interfaces is based on (except for D3D12). Once again, the challenge is bridging between the 32-bit interface to OpenGL that 32-bit apps will use and the 64-bit interface that the system OpenGL library provides.
Another issue that we had to solve was applications which 'hook' into the standard Windows OS functions, to alter their behavior. Steam's in-game overlay does this, for example. We had anticipated that need and designed for it. However, it turns out that the particular way that Steam hooks into the functions interacted badly with the way our custom compiler was generating them. It wasn't too hard to fix once we figured out what was happening. The figuring out was the hard part. It's always the way. :)
So, that's where we stand today. We'll keep you updated as we make progress.
Pro Tip — Turn Automatic Updates Off
By: Ryan Abhiram
Don't want your Mac to automatically update to Catalina so CrossOver can continue to run your Windows software? Then follow these two simple steps to avoid the automatic update:
1.) Turn off Automatic Updates. On Mojave, the setting is in System Preferences > Software Update. On High Sierra and earlier, the setting is under the App Store Preferences.
2.) You will still see occasional notifications that the update is available, but you can dismiss them and continue running your current version of macOS.
3) As always, be sure to have a current Time Machine backup. In the event that Catalina is installed, reverting to the previous OS will involve the assistance from Apple Support (1-800-275-2273) and a backup is needed to return to a working state. If you don’t already have a backup, you can find the instructions for setting one up at https://support.apple.com/en-us/HT20125
Marketing Ballyhoo —What This Means for Our CrossOver Users
By: Jana Schmid
Catalina has not dropped yet. But when it does, we've got your back.
As previously stated in our last Catalina update blog post So We Don't Have a Solution for Catalina..Yet, we are good people. And if our product doesn't work, we believe that you shouldn't have to pay for it. We are automatically extending the support period for CrossOver macOS for three months for anyone who had an active license as of September 10, 2019. If we need more time on our end, you get more free support time on your end. If we get Catalina compatible CrossOver up and running in two weeks, you will still get an additional three months of support for free.
The best way for you to stay informed about our Catalina progress is through our macOS Catalina Update mailing list.
