Hello,

I'm using BOINC 7.8.6 on High Sierra and it worked until today. Now it's not connecting to the localhost anymore.
Apparently this is after I applied the latest Apple supplemental update for macOS 10.13.3.

stdoutgui.txt: empty
stderrgui.txt:
2018-03-07 17:17:42.244 BOINCManager[6591:365822] IMKClient Stall detected, *please Report* your user scenario attaching a spindump (or sysdiagnose) that captures the problem - (imkxpc_attributesForCharacterIndex:reply:) block performed very slowly (7.28 secs).

I already uninstalled/reinstalled. Whatever setting I apply to the firewall doesn't fix the issue (it doesn't even start to communicate outside as far as I can see).

What else can I check? Thank you.

SOLVED

- open Activity Monitor
- force-quit the process "boinc" assigned to the user "boinc_master"
- restart the BOINC Manager

I'll check again tomorrow if it works after a full Mac shutdown and restart.
