Why Aperture doesn't work with OS X El Capitan ?

Thanks very much – that sawed me:)

I've the same problem but on my aperture ( 3.6.) Onscreen proofing doesn't permit to click off !!! What can I do ?

Disable Quick Preview (enter the shortcut P), than you should be able to disable onscreen proofing as well.

Perfect !!!! Thank you a lot !! You save me and my photo work !🙂

You're welcome 🙂

Hello there everybody !

Made the jump a couple of days ago to El Capitan and I've suffered from the things as you did. However, this freezing / washing / slowness is not, for the moment, stopping me from using this perfect tool which is Aperture. I know we're just between us, users, however I'm asking my question hoping we'll finally get some minor debugging from Apple.

When applying a dodge or burn effect, Aperture adds a 1 or 2 pixels black border on the left and bottom borders of the images. As soon as you add another dodge or burn effect on the top of the other one, it increases or 1 or 2 pixels this black border. That, for sure, is not something wished and even applying one of those two effects on a very small surface of the image is adding that border on the complete image. I've even tried brushing out this border but the effect itself is generating that border.

The only solution I found is to export the file to a JPG and crop it of 2/4 pixels on the bottom and left border ... which is a pain in the @#*, time consuming and removing those pixels from images where I need them.

Anyone encountered the same problematic ? All the best and have a very good day !
