SD-card slot, iMac

Thanks, VikingOSX.

Yes, it is not only this one card, it is a general problem (and it started about 6 months ago), just after my Mojave-uptdate (could of course be a coincident, don't know if there's even a theoretical possibility, just sayin). I live very far away from an Apple Store or Service center, and sending it away would be a lot of hassle, and I need the iMac for work. If I can't fix this problem, I'll probably just go around it, by buying an external sd-slot than can be plugged into one of the usb-ports.

But still, there must be some moveable parts in there, controlled by software? I'm pretty confident it is not dust or anything like that. It's like the opening has tightened on the inside, making the whole thing become more narrow, but I don't know. When a card is inserted in a noral functioning sd-slot, also in mine before the problem occured, it is not like you insert the card, and it locks in. So: there is no lock to get stuck in a locked position, even if that is what it feels like (making it all seem more mysterious)

Pretty sure nothing is stuck in there, even if that now seems like the most natural explanation. There's a 3 year old around, but even the front of the iMac is way out of his reach, that's for sure. I've only used one card, and not every month, and nothing is missing from it, totally intact. The back of the computer is a «protected area», not exposed to debris, dust, scraps or anything that would make me suspect anything could have got in there. The strange thing is the evenness of the obstruction. It is equally hard to insert the card almost from start to finish, but it can be done (just, and I would think with a danger of damaging the card), like the vertical space inside shrank. I'll try to poke around in there once more. Thanks for all advice
