This is an Apple Mac Mini. It is not a Windows machine. It has been newly set up, so you can use it immediately upon arrival. It is equipped with a Core i3 CPU, 8GB of memory, and a 128GB SSD, so it starts up and operates very quickly. It comes with an Apple-original Mighty Mouse and Magic Keyboard. (Both use batteries.) Both MacOS and Windows 11 OS are installed, so even those new to Mac can use it with confidence. Since both Mac and Windows OS are installed, how about it for those interested in Mac? The SSD is divided into two partitions, and MacOS and Windows 11 are installed. Press the Option key while turning on the power, and the hard disk icon will appear as shown in photo 3, so specify the desired OS and start it up. Microsoft Office 2021 is installed on the Windows side, so you can use Word, Excel, and PowerPoint. All accessories are shown in photo 9. There are slight scratches on the main unit, but overall, it is in good condition. After the product arrives, please turn on the Magic Keyboard before using it.
