I am trying to format a micro SD card on my Mac via a micro sd SD card adapter. The thing keeps saying "can't modify partition map" in disk utility.
Does anyone know what the fix is for this so I can actually format the card and start writing to it?
I tried to format the SD card itself (called disk3s1) with no luck. Says "can't modify partition map"
Would erasing/formatting the Micro SD card reader fix the issue and if so which scheme should I use?
I am at a loss here of what I can do to fix the issue. Does anyone have any ideas here?
[edit] I tried to format the card via terminal and I get the "Couldn't open device" error.
So I am really at a loss of what to do here.
