Thank you for looking.
We would like someone who is knowledgeable about Macs to purchase this. It is slow. Updates are not possible.
I was using it with OS Catalina, but after initializing and reinstalling, it became OS X Mountain Lion.
I could not update it because I did not register an Apple ID. I cannot answer questions regarding this.
For those who understand and have knowledge.
For parts, etc...

Initialized
No box
No keyboard or mouse
Includes only the power cable.
Please understand.
