This is a CD that came with the purchase of a Macintosh Performa 6210. It has been stored at home for a long time. I have checked that it can be read before listing it, but it is old, so I cannot guarantee its future functionality. Please confirm the compatible OS, models, and other environments yourself. Please refrain from purchasing if you are sensitive to the condition, as this is a private sale, stored at home, and will be packaged simply and compactly. No returns or refunds accepted. Immediate purchase is possible, but it is also listed on other sites, so it may be sold out. If you are concerned, please check the stock in the comments before purchasing. Due to work, I may be late in responding, so I appreciate your understanding. I will do my best to ensure a smooth transaction. APPLE, mac, Performa
