Yeah, went back and looked at the app_info.

There is no section for the intel opencl in there. Guess I need to scrounge around and find one for the mac.

Edit..

TBar you got a intel Opencl for the app_info I can use?

Not currently. I removed the one at C.A. due to it's poor record of creating a large number of Inconclusive results. The tasks would verify eventually, however the App wasn't any better than the one available on Main.
Basically, it didn't meet my standards.

I'm considering attempting to build a new iGPU App in Yosemite using Xcode 6.1.1. As far as I know both the App on Main & the previous App were compiled in Mountain Lion. It's possible it may work better compiled in Yosemite. Of course, since I don't have an iGPU, the new App would be completely untested.
Hmmm, it may work in standalone on a nVidia card so I could at least tell if it works at all.

You don't need a new app. Just writing a definition section in app_info.xml and running the one you had before would do the trick. The easiest way would be to ask someone who's still running a Mac intel_gpu as stock, and get them to post both the app_version entries you can adapt into app_info, and the download urls.

I did much the same for CPU apps in my thread

SETI@Home Version 8 - app_info.xml files ... (all OS)

to ease people through the v8 transition before third-party apps were ready.

Just found an interesting Unit that has completed and been given credit.

750 TI on PC CUDA 50 vs 750 TI MAC OpenCL.

The CUDA 50 WASN'T even on Lunatics... It processed SOOOO MUCH FASTER than MAC OpenCL... I find this fascinating.

Which is why we were suggesting the Cuda app Tbar put together. Further optimization that is in work will make the newer version eventually be 2-3x faster than even the cuda 5/6.5 version he has now. You can take a look at his Mac to see how fast his 750ti's run if you want to see what the future looks like.:)

There are some Mac's around and some are running stock.
Some have more processing units and some are faster.
Some have compiled their own and some are still waiting for.

To overcome Heisenbergs:
"You can't always get what you want / but if you try sometimes you just might find / you get what you need." -- Rolling Stones

I don't see any SIGBUS Errors there. I've tried just about everything possible in Yosemite and I'm still getting these SIGBUS Errors. I suppose it's time to move up to El Capitan and try it there.

Flat Makefile build process under El-Capitan went pretty smoothly here (whether stock or pasting Petri's optimisations over the top), can't say the same for the traditional gnutools route (though still used ./configure to generate the sah_config for now).

My *guess* with the SIGBUS errors in yosemite is something to do with the boinc libraries, just because signals and busses sound like the stuff that boincapi+lib handle, signal trapping and IO of file and shared memory type. I used the prescribed Xcode project method for building those libraries, since the gnutools path seems unmaintained for Darwin in newer Boinc revisions.

Good to see some others getting their hands dirty to figure things out. Glad I put the Alpha code there so others can play while I keep trying to bolt down generic stock.

[Edit:] disparate buildsystems on Mac Vs Linux Vs Windows is the main sticking point, with each having a ridiculous number of quirks and breakages on top of Cuda version compatibility concerns. Have been testing out what will be needed to go to Gradle automation for the CPU portions, which will make future builds cross platform much more uniform (and eventually automatically regression tested and deployed to website on command).

Now I just need more monitors :/

Seems to be slightly better in El Capitan, however, I'm still seeing SIGBUS Errors with the App compiled in Yosemite. I did see a bonic-master Error in Yosemite dealing with the graphics section;

/System/Library/Frameworks/Security.framework/Headers/SecAccessControl.h:43:1: error: expected function body after function declarator __OSX_AVAILABLE_STARTING(__MAC_10_10, __IPHONE_8_0);
/System/Library/Frameworks/Security.framework/Headers/SecItem.h:421:39: error: expected ';' after top level declarator
extern CFTypeRef kSecAttrAccessControl
/System/Library/Frameworks/Foundation.framework/Headers/NSOperation.h:6:9: fatal error: 'sys/qos.h' file not found #import <sys/qos.h>
libtool: error: 'libboinc_graphics2_la-mac_icon.lo' is not a valid libtool object

This stops libboinc_graphics2_la from building, but doesn't seem to stop the two BOINC libraries needed by the compiler.
This is probably why I was never able to build an app from the seti-boinc folder, it kept failing with the graphics error.
Fortunately, you don't have that problem if you disable graphics.

The graphics don't even try to build in El Capitan, unfortunately, I'm back looking at the EXACT same ASM problems as before in Xcode 7.2.1. This time there is a new Error though;
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/System/Library/Frameworks/CoreFoundation.framework/Headers/CFLocale.h(172): error: extra text after expected end of number

I never saw that Error in Yosemite. I think I'm about to trash another 10.8 GBs of Xcode 7.2.1 and try an older version in El Capitan.

yeah can disable graphics and ignore those crappy OpenGL graphics libs.

When I enable graphics for XBranch, It'll be with Unreal Engine, and so Vulkan + DX12, and totally different non-screensaver purpose. Just because I want to cruise around in VR checking out the nanofarm...
