The battery of my Macbook Air High Sierra goes down very fast, something is definitely wrong.

I checked Activity Monitor and identified a process named cust that is using 200-300% of CPU:

  1. Does anyone know what cust is?
  2. Would a process using so much CPU cause battery to drain in 30 minutes?

Edit:

This is the output of ps -ef | grep cust:

This is the output of find / -name cust -type f 2>/dev/null:

    Never heard of it, could you add a screenshot of Activity Monitor showing cust? Could you launch Terminal and add to your question the output of command ps -ef | grep cust? – jaume Aug 6 at 15:13

    Thank you for adding the screenshot and running the command. The next step would be to find out where cust resides in the file system. Could you open Terminal and run these command find / -name cust -type f 2>/dev/null (the search may take a while, be patient)? This should output all files on your Mac named cust. There aren't hopefully many... could you add the output to your answer? – jaume Aug 9 at 16:12
  • I've attached screen shot with results of terminal command. Looks like it is coming from something called Bask Client. I'll need to do some Googling on that. Thanks. – sfmitch Aug 11 at 15:18

    Looks like you found the culprit. I've found some information about BASK Client here: shouldiremoveit.com/BASK-Client-202550-program.aspx. Is this a work computer? In this case, contact your help desk. If it isn't, you could rename the folder with this command: sudo mv /usr/local/BASK /usr/local/BASK-backup (sudo let's you run the mv command as administrator, you will have to type your password when requested) Reboot after renaming it and let's hope the issue is gone. – jaume Aug 11 at 15:51
