I upgraded one Mac to Catalina OS and all yoyo WUs are failing with computation errors.

I reset the project but the computation errors continued, so have had to switch to another project

Is this a known problem with the Catalina OS, or a local problem that I can work around?

Here is the Event Log:

BOINC Manager is working OK for collatz and I switched CPU processing from yoyo to NFS@Home and that is working as expected too -- it's just yoyo that is resulting in "computation error"

I assume this happens because Catalina dropped 32 Bit support and allows only 64 Bit applications. The wrapper is an 32 Bit app.

Can you upgrade the wrapper to 64-bit?
Anything from 10.5 onwards should be able to use 64-bit (not sure about 10.4), 10.6 can boot directly into 64-bit if the machine supports this, and anything from 10.7 onwards has a real 64-bit kernel.
The later versions of macOS tell you Boinc should be upgraded to 64-bit to be supported, if you run an older version of Boinc.

When will a 64 bit wrapper be available?

Nearly all of my computers are MacOS...

I don't have access to any Mac and don't know how to compile on Mac.

As I just learned in the PrimeGrid chat, compiling for the lowest target OS should create an application that also runs on the highest target OS.
In fact, when the PrimeGrid devs learned their software did not only run on Catalina, but on Lion as well, they were really happy.
Most important thing on their software was the wrapper, I guess.

So the message to Mac users is that we need to move to other projects if upgrading to Catalina or newer OSs?

I ran across this thread as I noticed that my Mac was also generating empty results.

I understand that the wrapper is currently 32 bit and the project admin does not have a mac to compile on.
I have a Mac and a development environment. Is there a chance that I can help by attempting to compile the wrapper for 64 bit and test it?

Cheers.

The admins don't seem bothered about losing Mac users.

The SRBase admins are looking for somebody to compile a Mac wrapper though:

http://srbase.my-firewall.org/sr5/forum ... =6323#6323

I tried, but the only Mac documentation I found was hopelessly out of date and my build kept failing with dependency issues

According to BOINC source code (https://github.com/BOINC/boinc/commit/c ... 52e6121e81), the BOINC client is no longer requesting 32-bit works on Catalina or above (not sending i686-apple-darwin to projects).

I think yoyo@home should try to detect this and stop sending WUs to those computers instead of sending them then let it fail.

Or you should try to release the wrapper source code to see if others are able to make a 64-bit wrapper.

I hope you are still willing to fix this instead of letting all new mac users to just run other projects.
