Question

I have discovered FahCore_a4 running, how do I get rid of this pest?

I thought at one point it would be a good idea to try 'Folding at Home' from Stanford University. I ended up saying forget it, and I thought I had uninstalled it from my 2010 MacBook Pro. Shortly after what I thought was the uninstall, the computers fans would run loud all the time. I never knew what was going on, until today when I decided to look at the activity monitor to kill a different program off that was frozen.

This is when I noticed FahCore_a4 running my CPU at some crazy 300% or higher. No wonder my computer has been running hot for months. I can force quit this thing but it comes back within a minute. There seem to be a few other things associated with it, such as 'FAHClient' I can grab a sample of this process /usr/bin/FAHClient...how do I go about getting rid of this thing for good? Can anyone help me?

MacBook Pro, OS X Mavericks (10.9)

Hello!!

If you still have this problem:

I had the same problem with the Folding @ Home application. Seemed pretty neat at the time huh?

I found an uninstaller here:

https://foldingforum.org/viewtopic.php?nomobile=1&f=16&t=24574

At the bottom of the page, there is an entry that leads to an uninstaller. Or: Here: Uninstaller

Install the program and it will remove all signs of F@H. This includes the pesky FahCore_a4 as well as all affiliated items. Restart your computer if you want to be sure!

This worked for me, I hope it does for you!

FAH runs a background process to use your spare CPU cycles to calculate folding proteins for Standford.

It's really only useful on desktop machines that one can open up and clean the dust out, which rules out nealy all Mac's now.

To remove the hidden program requires running the installer program again usually to remove and it's startup.

Thanks for the link. Don't know why this has suddenly started being a problem on my iMac, but it cured it pretty quick.

This suddenly appeared in my iMAC today, CPU spiked to 100% and never went down...

Then I found the FahCore,a4 .... no idea why it became active today. It's several years I "used" the Folding at home program.

Got the feeling something triggered the sleeping program today...?
