Seriously, if you are ok with Mojave, and you like to play your old games, there is no need to install the upgrade. Right now, we can only give you a suggestion: don't upgrade to Catalina. You can read more about Wine and Catalina in this thread. The developers of Wine are looking for a solution. As far as we know, Wine won't be compatible with Catalina, at least not in the near future. Those wrappers are created with a tool called Wineskin and a compatibility layer called Wine. As you know, we offer Mac versions of old Windows games, such as Hercules, Pharaoh, and Diablo. Unfortunately, the second problem is more serious. So if Ultima Underworld, Carmageddon, Heretic, and other DOS games don't work anymore, you just have to download the new version. We were hoping to include the 0.75, but it's not out yet, so we will have to wait. The new wrappers include DOSBox 0.74-3, which is fully compatible with Catalina.

Lucky for you, this problem is solved: we just completed a full upgrade of all the MS-DOS Mac wrappers, 300 games in total. This means if you have downloaded DOS games in the past from this site, and you have upgraded to macOS Catalina, you cannot play these games anymore. The majority of our DOS game wrappers were created with version 0.74 of DOSBox, which is a 32-bit application. So, Catalina brings two main problems for GamesNostalgia Mac users: the first one can be solved the second one, maybe not (or at least not yet). In fact, it includes an emulator that allows you to use 32-bit software (pity that it doesn't work for 16-bit apps, but that's another story). Just for your info, Windows 10 is less picky.

Mojave is the last macOS that runs 32-bit software. Instead, if your Mac has already moved to the beautiful Santa Catalina Island, you can only run 64-bit apps. With the previous OS versions, there was a warning, but you could still run old software. We have good and bad news regarding macOS Catalina.Īs you probably already know, 32-bit applications cannot be executed anymore in macOS Catalina. But, it also comes with a lot of problems if you are a retrogamer. MacOS Catalina has some excellent features, such as the iPad as a second display or the Apple Arcade.
