(moderation:
A new MacOS X Intel App is available from our Beta Test Page.
It is the first "separate graphics App" ("APIv6") for the MaOS X Intel platform. Furthermore it features some more tweaking with the sin/cos code and some prefetching instructions to speed up memory access in the "Hough" part. Many thanks to Bikeman for these improvements!
Happy testing!

The prefetching speeds up the "Hough" part of the code, which is also responsible for the variation in runtime between different workunits of the same frequency. I guess the variation should be reduced significantly wit this App.

You can safely ignore is. The app_info.xml has a line for people switching from 4.04 to 4.33 in order not to loose work of the 4.04 App. This leads to nothing more that this error message for those that previously used a newer App.

An effect of this is that probably people currently running "longer" workunits of a charge will see more speedup than those that are on the "shorter" end.

Fastest way to fix the permissions I found to "Get Info" of the project folder (einstein.phys.uwm.edu in BOINC Data/projects), show "Details" in "Ownership & Permissions" and click "Apply to enclosed items..." (confirm). This will apply the correct ownership and permissions the folder still has to all items inside, including the files you just put there.

4.33 has been made "official".
For the moment I'd say leave the app_info.xml in place; removing it will terminate all task in progress with a Client Error.

Apparently I made a mistake when publishing it; with Apps 4.33 "officially" downloaded the graphics application isn't recognized as such by the client and thus the graphics doesn't work there.
I'll re-release the same App as 4.37 in a few hours in a way that should fix the problem. Don't worry if you're still running 4.33, it's the very same code.

The problem persists even with 4.37. I'm investigating. As a quick fix typing
[pre]
sudo chmod +x /Library/Application\\ Support/BOINC\\ Data/projects/einstein.phys.uwm.edu/einstein_S5R3_4.37_graphics_i686-apple-darwin
[/pre]
in a terminal should work. I guess the same is true for the current official Linux App, though even fewer people will notice.

Ok, this should be fixed for 4.37 (and 4.31, too) for new Apps downloaded from now on.
