We are often asked if there is a Mac or Linux version of CSS HTML Validator available. We do not have native Linux, Mac, or Unix version of the full program with GUI* but you can still run CSS HTML Validator using a method described below.
*NOTE: There is now a native Linux command line port (no GUI) and native Mac command line port of CSS HTML Validator (no GUI).
Most of the methods (except Wine and CrossOver) require running Windows in a virtualized environment, which means you'll need a Microsoft Windows license.
Use Parallels Desktop to run a virtual Windows operating system on your Mac. This will let you run a variety of Windows applications in the virtualized Windows environment.
Parallels Desktop 18+ works with Windows 11 and improves performance on Apple silicon devices (i.e. M1/M2/Mx devices) .
Wine 9.0+ is the recommended way to run CSS HTML Validator (with GUI) on a Mac or Linux if you do not already have a virtualized Windows machine and do not want to buy a Microsoft Windows license.
Wine is a compatibility layer capable of running many (but not all) Windows applications on several POSIX-compliant operating systems, such as Linux, Mac OS X, & BSD. Wine also doesn't require the purchase of Microsoft Windows unlike Parallels Desktop, Boot Camp, VirtualBox, and other OS virtualization products. You'll also save gigabytes of disk space by not needing a virtualized Windows environment.
Download Wine here (new window). If given the option during the installation to support 64-bit programs then please choose it in order to support recent versions of CSS HTML Validator.

. In at least one test, Wine 4.0 (on a Mac) was not able to run node.exe
. However, it worked on a Linux machine.Note: If you encounter a clipboard registration issue (that may cause the system to become unresponsive and require a system reboot) then you may be able to resolve it using an alternate method of registration. If you encounter this issue then please contact us.

CrossOver is a polished version of Wine provided by CodeWeavers. CrossOver makes it easier to use Wine.
Use Boot Camp to boot into multiple operating systems including Windows.
Boot Camp is available in Mac OS X v10.5 Leopard or higher. See also this Wikipedia article.
You can use VirtualBox (FREE) to run Windows in a virtual environment on a Linux, Mac, or Solaris host. This will not only let you run CSS HTML Validator but also other Windows programs.
Note that while VirtualBox is free, you'll still need a license for Windows (which is not free).
Legacy Intel-based Macs can also use VMware Fusion to run Windows.
There are also other solutions from various vendors for running Windows programs on other host platforms.
