Thanks, I didn't notice that.

What the difference between the polarity button and the inverted mask
drop down yes/no?

A bit of communication with the team.  Perhaps, a “Welcome” or “Thanks for your 
offer.” Either is better than being knocked down yet again.

 Ok! fine! This solved the problem...

Thank you for these suggestions. I could enable openCL using the nvidia
driver for it seems that the nouveau driver does not support openCL (yet?).

I had to fix the opencl_memory_requirement to 500 (it was set by default
at 768 !?) for my card is a GeForce 8800 GT with 512M memory.

Thank you.

Well, darktable is open source, so there wouldn't be anything we could do 
about that. If you want to bundle stuff you are in general free to.

The darktable team doesn't provide binary builds. It's individuals who do 
that. For Windows that has been me, for OSX it's parafin and Pascal is running 
the Ubuntu PPA. We are just helping out by hosting the files along with our 
Github release. Now, if one of those individuals decides to sign their package 
they are free to do so. More power to them. But I will make very sure that no 
money from darktable (the little that we have) will be spent to make Apple 
even richer, just so we can help them getting more users for their OS. I'd 
rather ignore a thousand complaining users.

hi,

sorry to say but i find this really childish. what do you expect? the
one person with a macintosh computer who was kind enough to provide
the disk image in the past is on vacation. nobody else close to the dt
devs is equipped with the required hardware, nor qualified or
interested in doing anything about the disk image in the mean time. i
really don't see what would make the club less closed. this is a
do-ocracy. you provide a port/feature/translation/whatever everybody
will be happy to help as they can. there's no hierarchical structure
to tell you what to do. this is a fun project, and as such
self-regulating. if a macintosh port is needed for many users, the
chances are high that one of them would have the itch and provide it.

[..]

cheers,
