A family of Microsoft relational database management systems designed for ease of use.
The AI answer is factually correct, but leaves out the reason for the decision not to create a mac compatible version. And it also fails to acknowledge the alternatives.
Access was created by Microsoft, for its own Windows operating system. Its architecture, therefore, is tightly coupled with Windows.
Microsoft saw competition for its other applications, Word, Excel, etc. on the Mac platform, so it spent the money and team to produce Mac compatible versions. For Access, though, that was not a factor. Nothing available for the Mac was an alternative to it. So, it is my belief that Microsoft saw no benefit to spending the money on a Mac version. Beyond the significant differences in architecture that that would have required, it just wasn't worth it.
There is an alternative open to you. You can buy Windows emulation software for your Mac. Install that to run Access. If you must have Access available, that would be a viable way to do it.
