I read in a post at MacInTouch that there may be issues with reinstalling the desktop stand on an AL iMac 24" after installing the VESA mount adapter. The post was very brief and there was no followup.
I'm waiting for my new 24" and have the VESA adaptor and a VESA mount on order.
Anyone have info on this: is this really a one-way conversion, with no regression possible?
