My Mac will no longer read SD cards

I'm using a 27" iMac running Ventura 13.4.1. I have inserted an SD card in the usual port, but find it can't be read. How can I read the card?

Give this a try: boot into Safe Mode according to How to use safe mode on your Mac and test to see if the problem persists. Reboot normally and test again.


NOTE 1: Safe Mode boot can take up to 3 - 5 minutes as it's doing the following; 

• Verifies your startup disk and attempts to repair directory issues, if needed

• Loads only required kernel extensions (prevents 3rd party kernel/extensions from loading)

• Prevents Startup Items and Login Items from opening automatically

• Disables user-installed fonts 

• Deletes font caches, kernel cache, and other system cache files


NOTE 2: if you have a wireless keyboard with rechargeable batteries connect it with its charging cable before booting into Safe Mode. This makes it act as a wired keyboard as will insure a successful boot into Safe Mode.

It's 2 or 3 years old. It has worked successfully in my current Mac during that period, and it works well now in my mid-2011 Mac which runs OS 10.9.5. The problem may be something related to Ventura.


Some of the photos on the card were taken my Nikon less than 3 days ago, and they show up flawlessly in the camera's preview mode.
