Why is mountain lion so slow

I have been trying to download... why is it so slow??

May depend on our internet connection. Broadband (high speed) is preferrable.

  • Why is mountain lion so slow compared to snow leopard?

    Just installed Mountain Lion from Snow Leopard (skipped Lion).   I like the features of Mountain Lion but it is incredibly slow in overal start-up and general system responsiveness compared to Snow Leopard.
    Running iMac and Macbook Pro and both are the same in really slow performance.

    OK, been a busy week but I've installed RAM.
    Had iMac 2007 model (iMac7,1) with 2GB of RAM (two 1GB modules).   Upgraded recently to 6GB of RAM (one 2GB and one 4GB module), yes, I know this is above the original specs of 4GB, but this model does indeed support 6GB with Snow Leopard or newer.   This now works fine under Mountain Lion with no spinning multi-colored ball.   With a couple of applications like Safari and Mail open, it has (using Activity Monitor) just under 2GB free memory.   Page Outs are now a very small (close to zero) fraction of Page Ins.   So, it works well.     If you are not upgrading memory then stick to Snow Leopard as it is a much lower memory footprint.
    Had Macbook Pro 2008 model (MacBookPro5,1) with 4GB of RAM (two 2GB modules).   This wasn't performing as bad as the iMac with Mountain Lion but was still slow.   Anyway, upgraded to 8GB of RAM (two 4GB modules).   This is also now working fine with no major issues observed. 
    If running VMWare fusion, then a lot of the memory will be used up.   The free memory is very slim on on an iMac when running VMware Fusion with MS Win XP (ugh!), which I only do for a couple of scientific antenna analysis programs that I like to use that just aren't available on the Mac, but it is workable.  Occasional memory address messages appear from the guest OS but othrwise fine.
    So, in summary, if you have older machines (with low RAM) or have a multitude of apps open then Mountain Lion requires careful consideration as it needs just over 4GB when a couple of memory hungry apps open.  Do anything exciting andmemory usage will increase causing tons of Page Ins compared to Page Outs and you'll be running in slow virtual memory.   So, for machines that you won't upgrade in RAM stick to Snow Leopard.   For modern Macs with 8GB, 16GB or more, then all will work well.  
    I still wish they could make the memory footprint leaner though.

  • HT1338 Why does mountain lion make my computer run slow and my Safari too?

    why does Mountain Lion make my computer run slow and my Safari too? Please help!

    The problem is probably not mountain lion. It works just fine on my computer. And a few million others.
    If your computer is having problems, you can try to fix it with some simple troubleshooting maneuvers.

  • Why does mountain lion "bunch up" all my microsoft office documents that I have open when I hit f3? When I had snow leopard for example, if i had 4 or 5 different microsoft office documents open at the same time I could hit f3 and easily pick one of them

    Why does mountain lion "bunch up" all my microsoft office documents that I have open when I hit f3? When I had snow leopard for example, if i had 4 or 5 different microsoft office documents open at the same time I could hit f3 and easily pick one of them.
    Notice how in the photo, I can't identify which MS office document I would like to switch too. Perhaps since the Dashboard and Desktop windows are at the top of my screen now Apple doesn't let you have all the applications take up the full screen and be sized individually so that you can have a better idea on what to pick.
    I like the idea of grouping to an extent... If you have a bunch of random things it was hard for me to decifer between what was safari, chrome, or word. But now that they grouped them like this, if you have multiple pages of one program running, you can't switch between those pages easily like before.

    If I wanted to open any of my Applework documents I had to open them one at a time and resave them with pages. This could take weeks.I have 1000s of apple work documents.
    You don't have to open and re-save every AppleWorks document you have right now. Just wait till you need one, then do it. The documents aren't going anywhere.
    Am I dealing with Microsoft? This was a BIG surprise to me that Apple would release an OS without testing all programs.
    Frankly, it is not Apple's responsibility to ensure compatibiltiy with every piece of software available for OS X. That is the responsibility of the software vendor. Lion has been available to developers for several months before it's release, so Microtek had plenty of time to update their software. Yet they did not. How is that Apple's fault? I think Apple was very generous to give you a refund for Lion.
    I'm not trying to belittle your frustration but I do think your ire is misplaced.

  • I have seen so much response about the Mountain Lion update slowing down computers.  I am updating from Mac OS x 10.6.8.  What can I do to ensure the upgrade will go fine?  Do I unplug my external hard drive before installing, or keep it plugged in?

    I have seen so much response about the Mountain Lion update slowing down computers.  I am updating from Mac OS x 10.6.8.  What can I do to ensure the upgrade will go fine?  Do I unplug my external hard drive before installing, or keep it plugged in?
    Also, I have the 08 version of iWork. Will this cause problems for the update?  Can I update this AFTER I update the processor?

    Welcome to Apple Support Communities
    There's no reason to think that Mountain Lion will slow down your Mac. Just make a backup of your data before upgrading with Time Machine > http://support.apple.com/kb/HT1427
    Also, check that your apps are compatible > http://www.roaringapps.com Upgrade them to a compatible version or delete them before upgrading.
    The external drive won't make the OS X Mountain Lion installer fail, but it's better to unplug it during the upgrade.
    iWork '08 is compatible with Mountain Lion. iWork '09 includes OS X Mountain Lion features and can be purchased at the Mac App Store.
    To upgrade to OS X Mountain Lion, I recommend at least 4 GB of RAM. You can check how much memory you have in Apple menu > About this Mac

  • HT4414 When I try to purchase Mountain Lion i get an error message:  "We could not complete your purchase.  The product distribution file could not be verified. It may be damaged or was not signed."  I can purchase other apps, why not Mountain Lion?

    When I try to purchase Mountain Lion i get an error message:  "We could not complete your purchase.  The product distribution file could not be verified. It may be damaged or was not signed."
    I can purchase other apps, why not Mountain Lion.   I get the same message on my wife's IMAC.

    The only thing that worked for me was to boot in safe mode.
    Power down.  Then press power button and hold 'shift' key until grey screen with progress bar appears... Once booted and logged in just open safari and browse to applestore. 
    No trouble at all once I did this.
    Hope it helps.

  • Why does mountain lion keep crashing after opening lid?

    Why does mountain lion crash after opening the lid or after it is asleep

    When are you seeing these messages? When Safari is running? If so, some web site is trying to perform a Java attack.
    There is virtually no reason to have Java on in your web browser. Open Safari's preferences and turn off the check box for Java. Leave JavaScript on.

  • Why is Mountain Lion in "waiting" mode in my dock?

    Why is Mountain Lion icon in "waiting" mode in my dock? Why is it not installing? I'm running a newer iMac with sufficient memory. I'm installing from Snow Leopard 10.6.8

    Thanks for the advice. I selected cancel and restarted the process. It says it is downloading however, it disappeared and I chose to start the process again this a.m. I'm not sure whether or not it begins entirely again or carries on from before.  It seems like a long, drawn out process, doesn't it? I've noticed the feed is starting so I'll let it run this morning and monitor the process.

  • I have a macbook, and have heard mountain lion will slow it way down

    I have heard upgrading to Mountain Lion will slow my macbook down.  True or false

    I have the newest Mac Mini with 8GB memory and I'm still experiencing a considerable slow down in most processes since upgrading to Mountain Lion, especially when browsing. I feel like I'm back in the old PC days.
    So at least in my case, memory is not the answer. 8GB should be plenty. Any other pointers to increase speed would be appreciated.

  • Why is Mountain Lion not available for Mac Pro 2007???

    Why is Mountain Lion not available for Macpro 2007 eventhough this computer is not having old generation hardware like of 15years ago's computers!! I am surprised to know about that. when this mac pro have 2 xeon processor, 8GB ram, OS 10.7.5 (Lion) etc etc. so why is this not compatible for mountain lion???
    Very Sad for us - the buyer of so costly Macpro ....
    so does the Apple want to say we should buy or upgrade our purchased costly apple products every 5 years ??!!

    This is a user forum. We are all users like yourself. Conjecture about Apple's products is not appropriate discussion in these forums.

  • Any one else notice Mountain Lion very slow...feel like I am back on a PC !!!

    Any one else notice Mountain Lion very slow...feel like I am back on a PC !!! Open files, programs, rebooting, even shutting down takes longer.  Am I the only one?

    Must have been bad hardware would be my guess. That's the problem with vendors though. Windows really isn't the issue if you have the right hardware. It's like a Mac, really.
    The problem is that PC vendors have a tendency to rush their machines out with bad chipsets and a mish-mash of conflicting hardware. Take Vista for example. Besides the fact that it was a resource hog out of the box, there was really nothing wrong with it.
    Vendors on the other hand, rushed their PCs out without the proper hardware to run it in order to sell, sell, sell, which is what gave it a bad name. So yeah, people had issues. It also suffered the same issues as Lion and ML right now due to the fact that it wouldn't run on older machines and there was an uproar in the online community--sounds familiar enough to me.
    Oddly enough, even macs are running at the same specs as Windows today. 
    The majority of issues people tend to have is more with their PCs than with Windows and they have a tendency to blame Windows because of this without realising that MS develops software; not hardware (xbox aside). Whereas Apple develops both.
    Millenium was terrible though--I won't deny that.
    OSX may appear to work better, but that's because everything is designed to work together and we pay a premium for it because of the quality control on the machine. I can't help but feel that Apple takes a little more pride in their machines then PC Vendors do. In fact, Windows probably runs better on my Macbook Pro than it does on my PCs. I use it for very little these days though. I happen to like OSX and I'm addicted to the App Store.
    Basically, my whole outlook on the two is that MS is a people pleaser, they try to appeal to everybody and a plethora of PC configurations. It suffers because of this. Apple is a little more arrogant (but in a good way). They stick to their own configurations and don't worry about being everybody's machine. They take pride in their designs and configurations and they succeed because of this. It also allows them to take bolder steps.
    Neither is perfect and both have their strengths and weaknesses. Though I feel that Windows is often picked on for the wrong reasons, just as Mac users are often picked on by the PC community. It all boils down to a lack of understanding since Macs don't only appeal to the dumb and Windows does work quite well if you have the right configuration. No insult implied--it's just the common outlook from both communities and it irks me on both sides.

  • Why did Mountain Lion slow down my shut down and boot up time for my MacBook Pro?

    I had Snow Leopard, and not Lion.  My shut down time rose from about 5 seconds to 10-15 seconds.  My start up time also increased noticeabley.  Any reason why because I thought Mountain Lion was supposed to be faster.

    I have very few apps other than what came on my MBP.  I've checked most other, really dont think this is the problem.  My MBP is not junked/cluttered up.  Not many programs, just pictures, videos, and some docs.  Everything seems to work smoothly once on, but the start up and shut down times are still double what they were when I bought with snow leopard (Not Windows like, but scary close).  I cannot find any solution that will work.  My opinion, should not have to do a clean install for it to work.  Some folks have not experienced these issues, so I think its some setting or something else that is my problem.  I have 4GB RAM, and considering increasing to 8, but from what I have read else where thsi will not increase boot or shutdown, way even increase.  Right now, not sure if the new ML features out way the slow boot and shut down. 

  • Download of Mountain Lion too slow - why?

    I have just bought Mountain Lion from the App Store and for some reason it is taking a very long time to download to my Macbook Pro 10.6.8. It has been more than an hour an it is still at less than approx 1/4 of the way! How long does it usually take? my internet connection is fast and working just fine.
    I need to leave to work in a couple of hours max and take my computer with me and i am afraid it will not be finished by then and I'll have to interrupt the download, is this possible? can I re-start it when i get to work and have an internet connection?
    Pls help!!!!

    Thanks mackack,
    My hard drive crashed on me and I got APPLE to replace it (2T) . I decided since Mountain Lion was available, why not? I moved from Snow Lep.  My IMAC is mid 2010. Reinstalling my programs has been a chore but the only real problem so far is missing serial numbers for my roxio toast pro add ons. Where did I put those??? Anyway, I am just noticing as are others in my family, that this is really slowed things down a lot. And there is the nusence of having to put in passwords and permission requests because half the world is blocked by Mountain Lion for some reason. Hopefully apple works to make this better instead of me having to junk it to go back to snow lep.
    I've been struggling for a year trying to appreciate my imac more than my PC. and so far, I keep turning to my PC in crunch time. I do a lot of music production and I was expecting more. I have apple logic, but find adobe audition 1.5 more functional on my old PC.... go figure.

  • Mountain lion update slowed down my macbook pro

    hey guys,
    I just updated to mountain lion
    however, after the installation, my macbook pro has been noticably slow.
    slow booting, slow when operating installed programs, chrome/safari got slowed down as well.
    Also it freezes for couple of seconds and i was wondering why.
    If any of u r experiencing same problems or know how to fix it please kindly let me know!
    Thank you!

    Have tried everything possible, repairing permissions etc to no avail.
    You haven't tried everything possible or you would have a solution.  If you tried the most extreme possible solution (erasing the hard drive, then reinstalling the system and nothing else) and still had the same problems, you would have discovered that you almost certainly have a hardware problem.  For some solutions that you haven't tried yet, I'll refer you to the same two links I referred sylee48 to.
    As for that article, that's an extremely unprofessional piece of writing.  They publish - as if they were fact - the conclusions of untrained, non-technical users who do not have the necessary expertise to make such conclusions.  And they concluded that these were bugs that Apple should be working on.
    In fact, this may be one of the smoothest upgrades I've seen in a while.  (Boy-oh-boy, you should have seen the screaming here for the Snow Leopard and Lion upgrades!  It's positively peaceful in this forum compared to that.)

  • Why is mtn lion soo slow?, why is mtn lion soo slow?

    why so slow 10.8.4 is torture

    Hi Allan,
    I think it is a bit like .plists
    Over the years the regular posters in the various iChat forums and Communities that have been have found you can solve specific issues in iChat by deleting specific .plists.
    You can do the same things in Messages.
    Balanced against that you have issues that involve the integration of many apps and the potential that possibly many .plist are suspect.
    I have seen it suggested that people remove the 1/2 the contents of the Preferences folder and add things back in halves until an issue can be replicated and from there trying smaller amount to isolate a particular .plist.
    Time Consuming but possibly less invasive than some other methods.
    People then seem to come to a halfway house understanding that maybe removing all the iChat.plist will solve any issue the app has.
    In iChat 3 and earlier this used to reset the Start Up Screen setting and made you do it again.
    I know enough about iChat and Messages to know which .plist and when but not enough about other apps to attempt let alone suggest a similar approach.
    Deleting the Font Cache does seem to be a valid "maintenance" trick
    I would not do it with the Buddy pics in Messages and iChat though.
    It is easier to use icon mode and spot the corrupt one(s) that don't display and remove them rather than upsetting the whole thing.
    Chunking up some info seems to work but not all the time.
    I think people apply "Clean this cache" to everything regardless of it's  action.
