I’ve been having a few issues with the sd card reader on my mid 2010 MacBook Pro. A few weeks ago every sd card I inserted I could only read from, but not write to. I know the switch on the sd cards for enabling/disabling writing, and that was not the issue. After some googling I found out there is actually a switch inside the sd card reader, and that had gotten stuck. So I was able to flip that with a paper clip and everything started working again for the past couple of weeks.
Fast forward to today and I had the same issue not being able to write to any sd cards. I figured it was the same issue as before, but the internal switch is in the correct position as well as the one on the sd card. I thought a reboot may fix it, but after trying that without a sd card inserted I can’t get past the grey boot screen. If I turn it off and try to reboot with a sd card inserted it boots fine, but I am still unable to write to any sd cards. It also sounds like there is a faint constant clicking noise coming from around the sd card reader that I have never noticed before. Has anyone experienced this before or have any thoughts on how to fix it?
Thanks for any help!
