Since yesterday my Apple iMac no longer seems to recognise

This answer was rated:

Since yesterday my Apple iMac no longer seems to recognise my card reader for photos when I plug it in. Everything else seems to be working fine. I have tried 2 different card readers but both with same result!! Many thanks. Bruce.

CompExpert :

hi,
try to plug in the usb port that you know is working like your keyboard usb port or mouse.

also, try to plug in your card reader to another machine if you have one.

that will determine if your card reader is defective or your computer usb port.

if you try card reader on another computer and is working.

and plugin into imac keyboard known working usb port but system still not detected.

go to apple menu --->>> software update

install all available update and reboot your computer.

and try it again.

let me know if you still run into problem.

it might be not the card reader or usb port on your computer, but the memory card that insert into the card reader is defective.

Customer:

I already tried all of this apart from different compute (not available). Makes no difference.

No error message. Just does not transmit emial, but receives ok, When when close message it say message not sent. Don't think my memory cards have a lock switch. It was working fine just a few days ago and nothing has been changed.

CompExpert :

when you plug in your card reader, does it show up on computer desktop?

were you able to open it directly from desktop without going through iphoto?

Customer:

No.

That is how I normally open it. I do not go through iphoto, but I also tried that as well. Tomorrow I wiil take BOTH card readers (one is new but I could never get it to work)to the shop to have them checked out.

CompExpert :

yes please do that, seem to me it all come down to the card reader is defective.

Customer:

Let's hope that is the problem. Then it's easy to fix!! I will let you know what happens.

CompExpert :

:) thanks

hope you have a great weekend
