Hi,

After upgrading to El Capitan Boinc Manager was unable to connect to the client.
I re-install the last version. No luck.
I run the uninstaller and deleted the Pref and Data folder, then re-install.

BOINC keep saying it is unable to connect to the client.
Using the Console I found this log.

Is it talking about the wrong Mac OS version ?

Any help welcome
Thanks

Please make sure you are running the latest version of BOINC, version 7.6.12 available here.

Are you installing and running BOINC under an administrator account or a non-admin account?

Did you set BOINC up to run as a daemon or system service as described here? If so, please you may need to run the script again after upgrading OS X.
