Hey Riley, good to hear from you again! Sounds like we have basically the same machine. I have the issue with the green photos too (Rafa García was just telling me about it off list). Our MBP model does have the dedicated Radeon M370X card but it seems Darktable doesn't cause the OS to automatically switch, at least on mine. On that tangent I also just discovered that the person who writes gfxCarStatus has updated their application to work with newer versions of OS X. It's a little menubar widget that lets you override the OS and manually force the dedicated card into service. I'm going to give that a go and see if forcing Darktable to use the Radeon helps any. You may want to give it a shot too: https://gfx.io/ > Do you experience this at all? Or just in the lighttable module? Mostly just the lighttable module, but I'm a pretty light editor honestly. More than a few minutes in the Darktable module and the image goes in the garbage. :) I was the same way in Lightroom. I'll spend three hours getting things lined up in real life instead of spending five minutes in post. If I did use more than a few masks the darkroom module did slow down tremendously. I'd get the beach ball trying to switch back out into the lighttable module, menus wouldn't respond, etc. So yes I did notice that too. > I was expecting a big performance increase from my older 2012 Macbook > Pro, but that hasn't really been the case. I came from a 2011 MBP (2.3Ghz Sandy Bridge i7/16GB/512GB SSD/6770) and wasn't expecting more than a marginal to OK speed increase. The 2.0.5 update hit before my new machine arrived so I just attributed the slow down to old hardware. After the new machine failed to move any faster at all I became a bit more concerned. For now I've downgraded back to 2.0.4 and things are moving along better. Still not near as speedy as the desktop Linux machine but there is a large CPU/GPU/RAM gap between the two so that's probably some of it. I'm tempted fire up my old Mac Pro, upgrade the graphics card and slap a relatively cheap SSD in it to see what it'll do. There probably aren't as many Mac users with Darktable as Linux so I imagine all data from as many hardware configs as they can get will be helpful. Not to mention winter is coming and I can use that thing to heat the house! ;) Thanks again!
