"This item is temporarily unavailable"
Wiped my old macbook since I got a new one and want to gift this one. Trying to reinstall an OS and get the option of Maverick popping up. When I put in my APple ID I get the message "This item is temporarily unavailable". Tried wife's Apple ID and it says "incorrect ID or password" even though they're correct and she gets the verification code on her phone.
How else can I get an OS installed so I can gift this device?
MacBook Air 13″, macOS 12.5
