I have the weirdest bug: opening a photo into the "edit" window recalculates the edits and ties the "sharpening slider" to the photo's "red channel." There are no visible slider changes, but a beautifully edited photo is suddenly converted to peaked reds. This renders the sharpening slider and the editing panel more than useless – they damage the photo. I don't even have to enter the adjustement pane for the change to occur. Command + E is sufficient to recalculate, bringing my work to a standstill.
Everything since the last update has been working properly, at least until the latest "Digital Camera Raw Compatibility Update 5.01." I use a Sony NEX but only save JPEG and never RAW. The Sony Alpha NEX-5T is included in the update, but I'm shooting with a Sony NEX-5, which is an earlier generation model.
I've also confirmed the "sharpening/red channel" bug is present in Aperture v3.5 – RAW 5.01 – Build 718.1, and RAW Support 5010 – Build 91.8.
Is there a way to revert to the previous RAW build? Is there a patch? Am I just forced to wait on Apple?
