I have a Macbook pro 15" summer 2012 model. Its the base i7 2.3Ghz I added 16gb ram... But this still is such a slow computer! it takes forever to load everything... I did realize that this computer was very slow out of the box. so I upgraded the memory "ram" and this machine is still very very slow... I adjusted the video card to not auto switch thinking that it might be a video issue.. but still nothing... My inlaws came over this week and I was able to use their 2006 imac "which benchmarks at 2550 on bench geek" and it was faster in opening all programs and most funcionality then my Macbook pro!!! granted it was running snow leaopard and I am running mountain lion. Can it make that much of a difference? I am just not happy with this macbook purchase.. but I have been dealing with it... which I am not sure why... I am going to wipe out my hard drive then re-install everything and see what happens. I don't know what else to do. any suggestions?

MacBook Pro, OS X Mountain Lion (10.8.2), Very slow.. super slow!

    Wiping and doing a clean install will tell but it's a chore (depending on how much third party software you're running).


    Have you tried testing in a fresh account, or your Guest account?


    Or, have you tried starting in Safe Mode and see if the slowness still occurs?

    Restart holding the "shift" key.

    (Expect it to take longer to start this way because it runs a directory check first.)

    I will try the safe mode now. This computer was slow out of the box. I know my RAM is good because I tested it without any errors. "although there always is that possibility" In all honesty this computer hasnt gotten any slower with any added software. But I will try safe mode now. Thanks for the quick response!

    well I am currently in safe mode. and I don't notice any significant difference in speed. it took about the same amount of time to load and open programs.. I click on the app store icon and it takes over 1-2 min. for it to load. I select the iphoto icon and takes about 1-2 min to load. I select the itunes icon it takes 1-2 min to load. so if I select them again after I have loaded them once before it takes about 25-45 seconds to load them individually. this is just crazy! is this normal? the imac isnt that slow... if I open programs and look at my activity usage its using 75% of my memory almost all the time. even after i close programs and what not. but even if it says its used I still have some free and shouldnt be any issues with speed... so I have no idea whats going on. I think there might be some sort of hardware issue...

    I would tend to agree. Those speeds are unacceptable. Have you opened a ticket with AppleCare, if not do so now.


    Also, have you used Rember to test your RAM? It's a front-end GUI to the 'memtest' command line memory testing program. This application will allow you to select the number of test loops, as well as the amount of memory to test.
