New 20 inch i Mac just started not reading SD cards from it's slot?

There are a few things you can try to get your MacBook to recognize your Olympus SD card:

1. Make sure that the SD card is properly inserted into the card reader or the MacBook's SD card slot.
2. Check to see if the SD card is locked. Some SD cards have a physical switch that can lock or unlock the card. Make sure the switch is in the unlocked position.
3. Try using a different card reader or a different SD card to see if the problem is with the card reader or the SD card itself.
4. Try using a different USB cable to connect the card reader to your MacBook.
5. Check if your mac has the latest macOS update.
6. Check if the SD card is formatted in a file system that your Mac can read (ex: exFAT, FAT32).
7. Try running disk utility on your mac and repair the SD card.

If none of these steps work, it may be an issue with the SD card itself, and may need to be replaced.

It is because you are using a Mac. There are some suggestions here.

The Nikon download software is called Nikon Transfer 2. I would remove the SD card from your camera and slide it into the SD slot on your Mac. If you have an iMac, the slot is located just below the CDROM slot on the right side. Do not do this by feel. Look as you insert the card because if you insert it in the CDROM slot, you may not be able to extract it. If you have a MacBook or MacBook Pro, check the manual for the location. When the computer recognizes your SD card, it will either open Nikon Transfer 2 or a folder will appear on your desk top. If Nikon Transfer does not open, just copy your pictures from the SD card folder to a folder on your Mac.

The slot is for playing many, but not all SD cards. What movies do you think it should "read"

hello,

the reason your laptop wont show your sd card on the screen is because it is not reading the sd card.

it is not reading the disc either because
1. there may be a problem with the card reader,
2. there may be a problem with the slot on the laptop,
3. there may be a problem with the memory card.

to check if it is the card reader, try to use the same memory card reader with another sd card on another laptop and see if it will read it.

to check if it is the slot on the laptop, try to use a new sd card and a new card reader on the laptop to see if it works, if it does not, then you know where the fault is from.

finally, to test the sd card, try to use it on another laptop to see what happens. if it does not work then you can tell where the fault is from.

whichever the fault is, you can change them.

but if it is the card slot, you will have to open up the laptop and clean the slot carefully.

take care.

Use a large paper clip and fold it shaped. Gently insert it into the cd slot and drag the card out. My kid has done it twice so far. Make sure the power is off and if the clip hangs, don't pull.

1)When you use bloototh always check the phone bloototh and notebook bloototh should be a pair after that you can try...

2)When you use USB-device please install Samsung New PC Studio after that you can try....

1. You need to install your camera software on your new computer.
2. Restart computer.
3. Inset SD card.
4. Goto start open My Computer.
5. Look for SD card should see it under removable disk.
6. If still not working send MSG & we will go Further.
   

If your SD memory card contains more than 1,000 images, the camera will display "Communication Error". Use a card reader (if available) to import your images into the computer, or see about having some CD's made at a photofinishing business.

Blast slot with compressed air, especially if you use phone without the blank in thus mentioned slot for it has no cover. If this has no affect, than it is a hardware problem. Go to a Cingular store that has someone that knows the phone, I'd call ahead. Check the online manual, maybe.
