Owner of a 2015 MacBook Air 11 inch. Yes old but maintained in very good condition over the years. No games, no viruses.
For the last couple of years I've been getting error messages such as the one I have attached and other similar ones with "Com.apple" and "Commenter wants to use the “login” keychain"... "Please enter password"
At first I thought it was virus/scam/malware. I took it into an apple store to which they said it wasnt a virus or malware but a keychain problem. They worked on it for a solid 40 minutes and "fixed the problem" but then it happened again a few months later. I did the same thing again and on repeat they "fixed it" (this time a different apple store) and the problem occurred again weeks later. I tried even the apple support over the phone who couldnt solve it.
It seems very random when these messages appear- but never on the daily or weekly. Only monthly or just a few times a year. But I got it again last few days and its triggered me to post on reddit. I dont know how to get rid of something that apple support people at the Genius bar cannot fix. Seems the only way to get rid of it is to force shut down my computer, which I've done now at least 10 times.
What will happen if I keep doing this? or is there a better way of solving this issue without buying a new or another laptop? Besides this issue and occasional lag in speed, it works great still and I dont want to buy a new one if I dont have to.
EDIT: The "password" it is asking for it seems is my login password but that doesnt work. The box reappears straight away
