Well I have the same problem on a MBP JUL 2010... it's definetively a problem of the MBP reader.
If I attach any SD card reader on the USB, no problem at all with any SD SDHC card
same cards appear all locked when inserted on the buid in SD card reader.
The question is:
it's a software issue or it's a mechanical issue like NURV2600 post suggest?

Wow, two years later--this is apparenlty a fix that still works. I have an April 2011 MBP quad i7 2.2ghz (10.7.5) by the way. Thanks for the fix, weird as it may be.

Yep! Works for me, too. I have a 2010 Macbook Pro. Thanks, all!

The tape solution worked—it's quick and painless. I found a video: http://www.youtube.com/watch?v=a_XkvkHDveo.

Flicking the slider switch on the SD card to the middle postion worked a treat....Thank you to skatalite13.
Odd that you daon't have to do the same when using the card in Bootcamp

Great.. You solved my problem
On all the SD cards, if I keep the lock slider in between Locked and Unlocked, the computer will see it as read/write. If it's fully at unlocked, it'll be read only.
Locked ___:-:___ Unlocked

There are some answers in this and other threads:
1. sometimes a SMC reset works.
2. there are SD cards where the read/write lock position is in the middle for read and write!
3. the card is not correctly formatted. this sd card slot is mainly for getting photos into the computer, they should be formatted in the camera. Do not use this card slot as a replacement of the usb sticks.
4. the card slot may have a bit of flu, use a external card reader.

Quite apart from this being a really annoying problem to have, it is the last thing I expected from a brand new Mac Air. In the absence of substancial hard drive space and only having 2 USB slots, the SD slot is ESSENTIAL!
Come on APPLE, sort this out.
The bent pin solution worked for me eventually but it takes some fiddling and I am just waiting for it to stop working again! Thanks for everyone here, without whom I would be without my music!

Same problem, and tends to happen from time to time. What worked for me was going over the SD Card slot really well with a can of compressed air.
