Hi all,

I have installed Boinc Client yesterday on my macbook pro, with Sierra (10.2.4).
The version of Boinc I use is the latest I guess: 7.6.34

All worked fine and I managed to select a project and worked on it... Until tonight.
I don't know why but the manager stopped working and now, the manager cannot connect to the client (localhost)....

I tried several times and I tried to reinstall the software but i still face the same issue.

Any clue / hint ?

Many thanks !

Is the client actually running? BOINC consists of two main programs, the client - which does all the scheduling, caching and up&downloading - and the manager - which allows you to command and control the client through a GUI. Normally the message that the manager cannot connect to the client happens when you do start the manager, but the client hasn't started yet. So check that.

Thanks Ageless for your answer.
How can I find this client on my Macbook Pro ?

When I install the tool (from here: https://boinc.berkeley.edu/download_all.php) , I only have one installer and then, one app called BOIN MANAGER is installed.
I then launch this app and it worked fine few days ago.... But not anymore :/

I don't know much about Macs, so will have to leave the answer to that to one of our Mac gurus.

Can you check the Console app. It is an application in /Applications/Utilities. Do you see any errors related to Boinc?
