The only solution to fight the OS sloweness is to add more RAM. 8Gb minimum if not more. It might run well with 4Gb, but as soon as you do multitasking with complex program it's game over.
I just can't believe how Apple is messing up since OSX 10.7. Mountain Lion is even the bigger mess. I've been over 10 year on Macintosh but after those dissapointments finally installed Ubuntu 12.10 on my MacBook Pro (along with OSX 10.8) on advise of a friend. And surprise, surprise...Ubuntu does everything OSX 10.8 can + more, incl. notifications etc. BUT it runs super fast and has wonderful multitasking possibilities.
As a test I've even installed Ubuntu 12.10 on an old 2007 Mac Mini (2Gb ram)...and guess what! It runs fast, without lags! I wished OSX 10.8 was programmed as good as Ubuntu is
I'm crazed with this slow thing .... so many say so much, but really ..... it seems that adding RAM is not the actual answer, buying new macs is not the answer, and that there is systematic evidence that going backward to snow leopard works just fine and gets back to speed that we all need, want and paid for ....
am I right ....
I'm happy to waste time and money jamming in ram .... but if all it buys me is marginal gains, stopgap stuff, then why ??
is it the OS itself ?? I'm suspicious that it is YES .... and Apple says nothing on this because they don't have a fix until the NEXT OS .... but when is that .... and what levels of speed, ram and such will we all need to support another OS that is becoming what we all hated about Microsoft --- monster size but not really doing the job with more than horsepower and not smartpower ....
c'mon apple gang .... help us out with real info and feedback ....
thanks for any more clarity -- I hope I don't have to read 200 more forum notes .... to find no answer .....
If you run a systematic approach to determine what is actually causing the slowdown, then you may find it is some third-party software that is interfering. It may just take an uninstall and reinstall of that software, or it may require replacing it with compatible software/hardware. From what threads I have followed on this, that seems to be the predominant problem. If you have hardware with dedicated kernel extensions, where the developer has abandoned you and won't update the kext, then you're probably out of luck with Mountain Lion.
It also may just take reinstalling the OS. If the installer choked on something, then it might not be installed correctly. Booting into recovery and repairing disk and permissions, then reinstall might help in that case.
If you completely eliminate all third-party software, reinstall the OS, and you still have slowness, then your Mac just isn't capable of running Mountain Lion as configured.
I haven't run it on less than 4 GB of RAM, so I can't speak to that min requirement.
I did run it on a 13" Macbook Pro, Core 2 Duo with 8GB of RAM and it ran just fine. Generally, I had Windows running in a VM on that Mac, using up half the RAM. It was incredibly fast compared to my 2006 15" Macbook Pro running Lion (EFI not compatible with ML) with 3GB of RAM.
barney ... thanks .... I'm not lazy at all, but when all my life and biz is on my computer and people say "uninstall and reinstall ..." I see hours of time and no computer at hand and get worried and just cannot imagine that is the best answer Apple can offer us ...
but your thoughts help me have confidence to just go and slam the ram .... I'll max out (I think this rig can take 6) and hope for the best .... it's about time for a new MBP and I have delayed because a magic one is sitting in USA and might be mine FREE in just 3 or 4 months time .... saving me a few KKKKKK $$$$ ....
I'll install the ram (up from the 2 I have since birth of this MB) and let you and everyone know ....
running as it is, I'd call it non-functional for business and other work ... just too ratted up, slow, needing restarts, and all that
yes, have done permissions and such ... all except the aggressive uninstall things .... I don't have any oddball programs, using safari, pages, skype, and other mac programs .... iPhoto, iTunes .... so I am not so sure that outside silly stuff is the issue .... but then, cannot know until one does ALL of them, and I just don't see the upside in that kind of lost time and risk that the gear will not run at all !!!
thanks .... a LOT
It could be the amount of RAM. 2GB is likely not enough unless all you're doing is handling email.
A reinstall of the OS takes about 30 to 45 minutes. Depending on how long it takes to download the installer.
However, I would suggest you get an external hard disk and clone your current drive onto it using Carbon Copy Cloner or SuperDuper. That may have to run over night, but in the end you'll have a bootable external drive. You can use that for testing things out, and still have your internal functioning as it is. Just boot to the external when you have time, try a few things like uninstalling software and see how it runs.
Or, you can revert your system to the previous OS using a backup you made prior to upgrading. Then, you can use your Mac like you want, and boot into Mountain Lion on the external to try to see if there are other issues you can work out.
If you are using this Mac for your livlihood and Mountain Lion does not further that cause, go back to Snow Leopard. If you are near upgrading your hardware, don't waste your time with trying to make that old Mac work with Mountain Lion.
thanks again Barney-15E .... I appreciate a dialogue with learned calm folks ....
my external 500gb went kerfluey a few months back and that is one reason I'm not so quick to do the reinstall and such, am using 320gb for time machine but good point to carbon and invest that time
I'll go after the ram solution first (and overpay at Apple Store just so I don't have to learn how to do it !!) ... I suspect you are right that everybody pushed forward with upgrades that were more complicated ... but I'm not happy that if I am open only on mail and safari that I am getting this "slow, blocked" behaviour .... I would have thought not ... but hey, it is what it is .... (right now, I show 1245 used and just 545 free .... )
could a rebuild of mail do something for this (that is always open, of course) ??
logging out and back in is not clearing things either (my wife uses my MB sometimes) - often it will not start up clean (like 600 used and 1400 free) but more like 1000 used and 1000 free .... showing that the logging process is hanging up too (caches held ?) .... and I don't want to restart ... prefer to insist that it "just work" ... yeah, stubborn me !!
I've been on mac since IIci in '90 that put me way ahead of the curve as I started my own biz - touchtyping my way to stardom and some very trick deals !!! (among the first in the USA to send scripts using email !) .... so I get that one must advance .... have had 10 or more Macs and now know time is up on a 2008 MB that was bought when G4 screen busted and I had to do an overnight "new computer" ... ahhh ... thank god for MB then -- great answer and has been very good to now (got my money's worth, and it will still be useful when I get this fixed) .... hooray and bye-bye at the same time
I will keep in mind the revert back to old OS, but am not the type to want to do that ... yeah stubborn ....
thanks ... g'nite from Paris, France ....
I am using Kingston RAM in both my 2009 Macbook Pro and my 2009 Mac Pro. Both machines perform flawlessly (even with the Mac Pro running 8 GB of the factory RAM + 16 GB of the Kingston RAM). Newegg.com has good prices on RAM and carries Mac specific products. I did have a problem with Safari taking forever to open after upgrading, so I wiped the drive and did a clean install. Safari takes about 2 seconds to open (although I never use it, as I prefer Firefox). Regardless of what Apple claims is the minimum recommended RAM, I ALWAYS ignore the manufacturer. RAM is so cheap now that I would never run a Mac with any less than 8 GB.
As for the problems that a few posters seem to be having, I wonder if they have run the Apple Hardware Test, Memtest, and the manufacturer's software for hard drive testing (the last one will have to be run from a PC with the Mac hard drive hooked up to it, as no hard drive manufacturer can be bothered to create Mac version of their bootable hard drive test software). Several times over the years I have run across similar problems on PCs that were the result of failing RAM or hard drives.
I've been having this slow down problem with my 2009 MacBook Pro 15 since upgrading to 10.8.
I just increased my RAM from 4 GB (Apple's baseline amount that worked fine with 10.7) to 8GB and that has helped a lot. When opening a program for the first time it is still very slow but otherwise improved.
My wife's brand new MacBook Pro 13 w/Retina display came with 8 GB of RAM and hers has been slower than her 2008 MacBook Pro with 10.7. It still is slow in spite of trying all the advice in here.
I also was experiencing very unstable operation of Safari - random quitting 2 to 20 times a day after I went to 10.8. I solved that issue by switching to Chrome which hasn't failed once since I switched.
I doubt ML runs "like blazes" on anything, even if you'd strap it to the back of a Cheetah and light a firecracker. It's slow, noticeably slow, compared with everything that came before it.
Apple should put out a fix or do a new OS as soon as possible.
Everything about ML is fubared. I can't think of one thing that works as good as it used to.
For people at Apple to say we need to spend hours troubleshooting and fixing and tweaking is denying the reality that we don't want to do that, we don't have time to do all that, we don't have time to do any of this and we shouldn't have to d that. It should just work!!
My advice to Apple is fix ML and then stop trying to "improve" your OS.
My advice to you would be to try to find out what you have Installed that is making your Mac run slow. My five Macs are flying along with ML. The only few people with problems are the tiny percentage here in a troubleshooting forum. Many millions of others are having no issues, so look closer to home.
Shellinaya is absolutely right. Everyone who doesn't see that OSX is an overloaded, buggy & slow piece of software is to much of an Apple fan. I'm using Apple products since over 15years so I'm not just one of those fan boys who jumped on the Apple-train because it became cool. But with OSX 10.7 & 10.8 it has been the first time I'm really dissapointed and annoyed by Apple.
OSX is slow, point! Someone who just surfes the net, writes some mails, texts or uses iTunes might not have those problems. But for those tasks I could also use a tablet computer... As soon as you do some real multitasking, OSX 10.7/8 becomes almost unusable. That's the case on my 1.5y old MacBook Pro. You know where I don't (or barely) have those issues? On a brand-new iMac with 16Gb RAM. Yeah, 16Gb!!! How crazy is that? No amd64 system should need more than 4Gb RAM to run well!
The very newest Ubuntu 13.04 (which is very similar to OSX in usage and functions) runs on my old Mac Mini (early 2007 version) with only 3Gb ram. It runs extremely smooth & way better than OSX on my MacBook Pro. Why? Well because Ubuntu is programmed well & clean, handles hardware well and doesn't seem to be an outdated mess like OSX.
OSX (=OS10) is getting old and similar to Microsoft Apple builds their new software on old one. It's time for a fresh OS11 which feels as fast & snappy as OSX used to be. Those were the qualities of Apple, those were reasons for me to not use Windows - among other reasons!
And some words to people like John Galt and co: If I buy software I want it to be usable right away. It's not my task to search for mistakes of the system before using it. I've been using OSX on various systems, re-installed it many, many times...but it's always the same with the latest OSX versions. Back on OSX 10.5 you could do whatever you want & install anything (well almost) and the system never got slow.
@petermac87 having many contacts in the IT business I can tell you that a lot of people have issues with OSX. The problem with many Apple-fans is though that they can't criticize their beloved company or simply always re-buy the newer Apple product - even though their old hardware would still run properly with a good operation system.
