What's in and what's out for CrossOver 27

by Meredith Johnson

Do you prefer to hear good news first or bad news first? I struggle to figure out if I should lead with good news or bad news, so I'm going to start with good news for all (yay!), then the bad news for a few (boo!), then more details about the good news (yay!). Here goes...

Good news

The CrossOver team has been working really hard on some new things for CrossOver 27 that haven't even made it into a Preview build yet. Very briefly, these new things include:

- Some fresh UI changes for gaming bottles.

- ARM64 builds of CrossOver for both Mac and Linux.

Bad news

To make room for the new, we had to make some tough decisions. The bad news is that we will be removing some legacy support options starting with CrossOver 27:

- CrossOver Mac 27 will only run on macOS Sonoma or newer, and only on Apple silicon Macs.

- 32-bit bottles will no longer run, full stop. We've been warning about this since CrossOver 26 was released, and you will need to create new 64-bit bottles to use CrossOver 27 and beyond. Almost all 32-bit applications run just fine in a 64-bit bottle.

Now how do the cool new features relate to the bummer news items? So glad you asked!

UI changes and system requirements

Supporting older macOS versions is really hard for UI development. Our team has been working around bugs that only affect much older macOS versions for many years now, and our slick UI changes are just exacerbating the problem. According to our back-of-the-envelope math, 97% of our users today are on macOS Sonoma or newer.

Our users on Intel-based Macs have also dwindled to a very small number. Furthermore, macOS Tahoe only supports a very small subset of Intel machines, and macOS Golden Gate will not run on Intel at all. Supporting both Intel and Apple silicon Macs diverts a lot of our testing resources away from the machines the vast majority of our customers use, and we haven't been able to justify spending developer resources on Intel-specific bugs for a long time now.

Pivoting to supporting only Apple silicon and only macOS Sonoma and newer means that our testing and development will be more focused and more effective, resulting in a higher quality product. Additionally, this change also makes all of our upcoming UI changes possible. These changes will start trickling into Preview releases soon, so keep your eyes on the release notes!

ARM64 and the 32-bit bottle problem

As I said above, we're working on support for ARM64 builds of CrossOver for both Mac and Linux. Our Linux builds have been live as a CrossOver Preview exclusive since November 2025, and our Mac builds are making nice progress and should be available in a Preview release soon.

Having an ARM64 version of CrossOver has been a huge development priority for our team for many years. ARM64 continues to be a very compelling platform in the Linux ecosystem, and we fully expect that trend to continue. And of course, Apple silicon uses ARM architecture, so CrossOver Mac has been targeting ARM64 ever since the first M1 chips were released in 2020. Currently, CrossOver requires the use of Rosetta 2 to translate x86_64 instructions to ARM64. Rosetta 2 will be largely discontinued with macOS 28 in 2027, and our ARM64 CrossOver build will run without Rosetta 2, allowing for a seamless transition for our users.

While supporting ARM64 is very cool, and in fact necessary for the survival of our CrossOver Mac product, it does mean the end of 32-bit bottle support. We needed some very invasive hacks to get 32-bit bottles to work on even x86_64. Trying to extend those hacks to ARM64 would be an unimaginable technological burden, if we could pull it off at all considering ARM64X on Windows doesn't work that way. These considerations, in addition to the fact almost all 32-bit applications run just fine in a 64-bit bottle, mean that we had to discontinue 32-bit bottles to save CrossOver Mac and continue expanding our supported platforms for CrossOver Linux.

Ending notes

And finally, what do you do if you can't upgrade your Mac, or you can't get your favorite application to run in a 64-bit bottle after trying and contacting our support? CrossOver is not a subscription, and you can keep using CrossOver 26 and prior versions. If you won't be making use of CrossOver 27 or newer, don't renew! Our product no longer works for you, and there's no need to pay for a version you can't use. Please note that older CrossOver versions may not be compatible with newer operating systems, and it's possible your application could update and no longer be compatible with an older Wine version, but we do nothing on our end to prevent you from using the CrossOver versions you already paid for.
