No cardreader since i have updated to Yosemite

weird again.

but its my own fault.

I should not update to a newer version till its about 6 months old,

because everytime i do so - just getting troubles with my mac 😟

Since i have upgraded to Yosemite yesterday my cardreader doesnt work 😟

It just tells me "the medium cant be read by this computer"

It worked fine all the time till yesterday when i upgradet.

any idea - any update coming up ?
