    I have a mid 2011 base iMac 21.5" 500gb HD which runs slow - I get alot of beachballs. I have upgraded Ram to 8 gb but does not help.

    Any suggestions?

    Thanks

    Beachball is usually the RAM but not always. Either way, more information would be helpful.

    What kind of stuff are you doing when it happens? How much do you have open at one time? Also, what kind of information is your activity monitor showing as far as RAM and CPU usage?

    If it is the RAM, even with 8GB, it could still run a little sluggish. It all depends on what you're doing which is why I ask the above.

    What do you define as "slow" and "a lot of beach balls" by the way? Also, you say you use it for email and internet? What program and browser are you using? Firefox, for instance, has been known to cause a lot of beach balls. Especially when it has been on the computer for awhile.

    Unless it's something going on with your HDD you should be getting plenty of speed with that much free RAM and CPU. My iMac usually has no more than 4GB of RAM free and still runs fast by my standards.

    I am using Safari - When I turn on the iMac - I usually get message "No internet Connection" then it works?

    Thanks

    Are you on the latest firmware? There was a patch released for the wifi issue.

    Although I fail to see how that constitutes as the computer running slow. It is just taking a slight amount of time to pick up the internet connection. Unless it's for an obscenely long time that seems like normal behaviour to me.

    How do I get the wifi patch? Is that under software updates?

    Thanks

    Yes, it would be listed as an iMac firmware update.

    In additon to machine update / checks, also perform a Speed Test on your Internet link. What speed did you buy? What speeds are they delivering?

    For speed test link, surf: http://www.speedtest.net/

    Hope this helps as well....

    I forgot to mention I am still running Snow Leopard. Should I upgrade to Lion?

    Thanks,

    I'm having the same problem with the same machine. I haven't added anything to my iMac - it's a stock standard mid-2011 base iMac 21.5". I've only had the iMac since January 2012. I've noticed over the last few days that the machine is super sluggish, especially when using a browser. I primarily use Firefox (which is up to date), but using Safari gives me the same results - incredibly slow, lots of beach balls and it takes five minutes or more to load the simplest sites. Even when it does load sites, it hates me scrolling down the page and will launch beach balls regularly and seemingly at random. It seems to hate Twitter the most, which is unfortunate because part of my job is maintaining a daily social media presence.

    My iMac specs:

    Processor 2.5 GHz Intel Core i5
    Memory 4 GB 1333 MHz DDR3
    Graphics AMD Radeon HD 6750M 512 MB
    Software Mac OS X Lion 10.7.4

    I currently have 413.84GB free on my harddrive out of the available 499.25GB. I also have a 1TB WD Passport external HD attached via USB to the computer as a main backup drive. It has over 800GB left on it. I use a bluetooth mac keyboard and magic trackpad.

    I recently updated to 10.7.4 - wondering if it could be some issue with that update? This is my main work machine, so I'm very eager to get this sorted out. If I thought it needed repair, I'd book it in post haste. (I have AppleCare on this machine, thank goodness.)

    Any suggestions as to what the problem is would be appreciated! Thanks.
