I'm a long-time BOINC user with SETI; ran it for years with no issues. With SETI out of the picture, I wanted to use my processor downtime to tackle COVID-19 research. Signed up with Rosetta@home and completed a couple of jobs. And then a couple of weeks ago ... "No running tasks." I signed up for World Community Grid and RNA Word -- same thing, No running tasks. When I look under the Projects tab, each item is showing "Communication deferred" with a countdown timer. When the timer runs out, it contacts the server ... and a new countdown begins.

I'm on a Mac Pro running OS 10.6.8 with 2 x 3 GHz Dual-Core Intel Xeon processors. I'm currently running BOINC version 7.2.42 -- the same one I've been running with no issues until recently.

That brings me to my next issues. When I try to upgrade to 7.14.4, the installer launches but then I get an error message, the main focus being the message "Library not loaded: /usr/lib/libc++.1.dylib" I believe that, in theory, 7.14.4 should be compatible with Snow Leopard -- but maybe it really isn't?

Thank you for your consideration and advice.

Looking at other issues which throw up that message on Snow Leopard the solution might be to install qt5 which you can get from git

./configure -developer-build -opensource -nomake examples -nomake tests -qt-sql-mysql

I have never used a Mac myself so am unable to test this solution.

UPDATE: I took the nuclear option and updated my OS to 10.7 (Lion). Everything's working again.
