Extremely slow iMac

Question

A few months ago I bought a new iMac.  It has 16GB of RAM, a 1TB Fusion Drive, is a 21.5" Retina model, and has a 3.1GHz Intel Core i5.  It has Intel Iris Pro Graphics 6200 15.36MB.The issue is it runs VERY slow.  At first I thought it was my imagination.  It&#x27;s a secondary Mac.  My primary computer is a MacBook Pro with a Core i7, 16GB, and 1TB SSD Drive. I thought a Core i5 and Fusion Drive are maybe just much slower than a Core i7 and SSD Drive.A couple months ago though I used a friend&#x27;s 7 year old MacBook Pro with 8GB and a standard drive and much slower processor to realize that it was faster than my iMac and this was with multiple windows open.  For example I have opened Safari on the iMac with nothing else open and tried to simply watch a video on a news site and it kept stuttering and beachballing. I was going to do something about it at the time but I knew Sierra was coming out in the near future. I thought maybe something was just quirky in the system and a update to a new OS may fix it so I put up with it being slow since it was a second computer but no such luck.  It&#x27;s as slow as ever.Does anyone know what could be causing this?  Since it&#x27;s always been like this I wonder if it&#x27;s some type of hardware problem with maybe the Fusion drive or possibly the memory or even CPU.  If necessary I&#x27;m glad to make an appointment and go into the Genius Bar and it would be under warranty.  Yet if it&#x27;s something simple I can diagnose and fix with time at home I would rather do that.  Is there any type of speed test or diagnostics I should do on it?  I have some background apps running but it&#x27;s not as many as I have on my MacBook Pro.  I just wondered if something is using up resources and causing the speed to be slow.  Yet boot up also takes a long time so it&#x27;s not just while it&#x27;s running.Thanks for any advice or ideas.

May I ask why you have a bittorrent.uTorrent installed on your computer?

stevejobsfan0123 · Answer

Try uninstalling Webroot and see if the problem persists. In general, you don&#x27;t need such software on a Mac and they usually degrade performance.

Allan Eckert · Answer

I would also suggest that you uninstall your Torrent software to find out if it is culprit causing the performance problems.

John Galt · Answer

That Mac&#x27;s Hosts file appears to have been modified.If you know the reasons for that, proceed on the basis of that knowledge.If you do not know the reason, please read Fixing a hacked /etc/hosts file.Uninstall "Webroot" by following its instructions, but consider the following comments.I suggest you read this recent post: Re: Will this work?Does "Webroot" interfere with "TextExpander"? I don&#x27;t know, but while "TextExpander" may be useful, "Webroot" is useless garbage. Unfortunately it may prove difficult to eradicate, a notorious problem with ill-conceived or poorly written software.When I installed "Webroot" for testing purposes some months ago, I followed their developer&#x27;s instructions to quit the app and drag it to the Trash. Doing so proved ineffective in removing all its system-altering components. Since its uninstallation instructions failed, I completely erased the volume on which it was installed. The user posting the Discussion I referenced earlier also decided to pursue that route. That&#x27;s what I recommend. Let me know if you need help doing that.

markwco10 · Answer

Thanks for all the replies. I have removed both Webroot and BitTorrent.  I have an app called AppDelete that is supposed to remove all traces of an app.  I hope that took care of all of Webroot.  I will say at this point the computer seems to run faster.  I will use it a little more to try to figure out if it&#x27;s up to speed where it should be. I realize it won&#x27;t be as fast as my laptop since that&#x27;s an i7.  All of these suggestions definitely helped.

Allan Eckert · Answer

In the testing I have done on AppDelete, I found it to be dangerous in what it removed from the system. It usually ended up breaking other applications and/or the system on the Mac I was using to test it. Hence the reason I recommend strongly that it not be used.
