In order to be able to apply some external delveopers' plug-ins in Aperture 3 I need to re-launch the application in 64-bit mode. How can I do it?
By default in 10.6.8 it should be in 64 bit mode but to check and change it in Finder highlight Aperture, the application, and go command I to open the info window and look about 1/4 of the way down
(Note this is from Lion so it is slightly different then what you will see)
Thanks for your comment. It is exactly the same in Snow Leopard which I have, but I suppose the reason why Topaz Lens Effects x64 is not working is in something else.
Will touch base with the developer to find out.
