MacBook Pro boots up really slow

    Hello everyone!

    I have a couple of issues with my MacBook Pro and I was hoping someone could help me.
    It's about a mid-2010 i7 2.66 GHz MacBook Pro, 8 GB ram, running Mavericks.

    The problem is as follows:
    My MacBook takes between 3 and 6 minutes to boot up. It is the kernel stage that takes really long. The rest is fine. Besides that, the battery is also empty very quickly. After about 1,5 or 2 hours of surfing on the internet, the battery is empty.
    I recently put in a new battery because the other one said it should be replaced. I hoped this would fix the battery issue and maybe even the boot up issue, but unfortunately the battery is still empty very quick and the boot up is still slow.
    I think the boot up started to get slower around a year ago. It then took like 1 or 2 minutes instead of the couple of seconds it used to take. About half a year ago that boot up time significantly got worse. And I think it may have gotten a little more worse after I installed Mavericks a little less than half a year ago.

    Besids that, there are a few more issues. I'm not sure though if they are related to the slow boot up or to the battery.
    When I connect or disconnect the adapter to my MacBook Pro, everything freezes for a while. I usually can still move my cursor around, but video or audio freezes and I can't open new windows or something like that. The freezing takes between 30 secs and 2 minutes. This is something that started to happen about a little more than half a year ago I think.
    Also, when I try to save something, a document or an image from a website, it takes a while for the Finder-popup to show my folders. It used to immediately show all the folders, but now it takes a while to load them. This is something that started to happen a couple of months ago.

    I honestly have no clue why these things are happening.
    I already checked my harddisk. I used Disk Utility and then the First Aid tab to check my harddisk and everything is fine. I also have over 100GB still available, so the harddisk is not too full or something.
    I also checked the activity monitor. I'm not too sure what to look at on the monitor, but as fas as I can tell, there is nothing strange going on.
    I also already reset my PRAM and SMC.

    Does anyone have any idea how to solve these problems? Or maybe just point me in the right direction?

    Many thanks in advance!

    Did you run the Apple Hardware Test?

    I'd do that and check the syslogs (console app is in the Utilities folder within the applications folder)

    Are you using an SSD or a HDD?

    I am using an HDD


    No, I haven't run the AHT.
    I was looking at it this morning, but I wasn't quit sure yet how it worked and what exactly I needed to do

    What kind of things should I be looking for in the syslogs?

    I just performed a normal AHT test (I don't have time of an extended one right now), but it said "No trouble found".

    So I guess we can say it's not a hardware issue?

    Is there a way to find out what software could be causing these issues? I rather not format/reinstall the whole thing, so it would be nice if there is a way to find out what is causing the problems.

    That's why your Mac is taking so long to boot. I used to have a 7200rpm drive and took about just as long to boot up, even after a clean install. It could be the sign of hard drive failure.

    Actually, hard drives do slow down. Physically they do not. They still spin at the same speed and such, but as the hdd becomes more and more fragmented from writes and deletes, the read head will have to search over more and more area to find/extract the files being called for.

    Anyway, if you want your Mac to just start in 11 seconds, buy an SSD.

    If you still wish to stick to your current HDD, go repair disk permissions in disk utility first and check whether the performance will improve or not.

    I did repair the disk permissions as you suggested. I'm not really sure if it made a difference though.

    I guess I should indeed buy an SSD, because I can't think of any software that could be causing these problems since I haven't really installed anything lately.

    Here's my 2011 MBP booting up with an SSD. Watch both videos.
