There are a few things to take into consideration when trying to answer this question. The first is that ACDSee is a photo management software application and Mac is an operating system. In order for ACDSee to be compatible with Mac, it would need to have a version that is designed specifically for the Mac operating system. As of right now, there is not a version of ACDSee available for Mac. However, there are some workarounds that may make it possible to use ACDSee on a Mac computer.
One workaround would be to use virtualization software such as Parallels Desktop or VMware Fusion. This would allow you to create a virtual environment on your Mac where you could install Windows and then run ACDSee within that environment. Another option would be to use Boot Camp which lets you dual-boot your Mac into Windows so you could use ACDSee natively in Windows. Keep in mind though that neither of these options are officially supported by ACD Systems (the company behind ACDSee) so they may not work perfectly or at all in some cases.
If you absolutely need to use ACDSee and don't mind using Windows, then your best bet is probably just using Boot Camp or one of the aforementioned virtualization solutions. Otherwise, there are other photo management applications available (some of which even have versions specifically for macOS) that might better suit your needs.
