Why is Lion so slow?

I installed Lion on a relatively new MacBook Pro (released early 2011) with an i7 dual-core processor. It is painfully slow, much slower than Snow Leopard was. Even things like surfing the internet (using Firefox) is very slow, and I see the little rainbow circular icon frequently.


Any ideas?

MacBook Pro, Mac OS X (10.6.7)

How long since you installed? sometimes spotlight will take a long time to index your drives and slow your computer down a LOT. Are you backing up with Time Machine? That can also slow down the computer until the backup i done.

That's great news incepted but unfortunately for a lot of us Apple has made sure the minor update to lion is out of reach if you have hardware that is 4 yrs old. I cannot install it on my BlackBook even though I have had lion installed. Would be interested to see if anyone has managed to install in older hardware or is this just Apple conning people into purchasing new hardware??? I suspect so. As for anyone who has now resolved their buggy lion issues then brilliant news!!

@Cpl BadBoy, I'm sure Apple will create a 10.7.12 update which will correct all the problems whe have encountered... I hope for them they will do an update, otherway they will need to replace a lot of graphic cards, motherboards cards which will be destroyed by Lion, and it will cost more more money to them ...


Guys which have a desktop computer like macmini, or g5, may not pay attention to the hot temperature, not like a laptop which burn your legs ...

???
Why do you think any hardware can get destroyed by software?

Guys which have a desktop computer like macmini, or g5,

Lion does not run on a G5.

I Yesterday updated Safari and all the other Apple-sw that was ready for downloading. So far everything looks much more snappy and hasnt seen the spinning ball at all.


This is probably not an Lion problem, but somewhere else, somewhat else.


My feeling is that most of us with major problems with this hang situations are guys with MacBook Pros around 2009.


Cross my fingers that this will last and that the problem is gone. We should all remember that if you first got this problem it doesnt help going back to SL. It just follow you back there.


For now I am happy, but will it last? ......

another Apple discussion troll 🙂



G5 ok, i mean desktop computer, sorry...


Anything which make your computer hotter than the normal, accelerate the destruction (erode) of the material...

I remember an iphone 3G which i have updated to iOS3.1... The update have destroyed the wifi component of my iphone 3G... I have built another one (7000 Dollars here)...


So be careful with the temp sensors of your computers, if temp is normal, everything is ok, you are lucky, but if you seem strangely hot temp, make the necessary to avoid burning your computer....

By way of an update, my early 09 MBP ran like a dog under Lion - kinda lived with it but never happy


Pleased to report that after the £13 update to Mountain Lion it's like a new machine!! Really snappy, Safari, Chrome and FF fire up in an instant - really happy


Gutted that AirPlay doesn't work on pre-mid 2011 macs, but have found a fix for that so can mirror perfectly to the TV


Chuffed to bits

Jul 26, 2012 7:57 PM in response to fced

sorry i mean 700 dollars...

I don't have tried Chrome, but Safari work well... The only problem i have found in Safari, is withing some text fields on some websites, sometimes, the text cursor disappear, you need to click and type a letter to find where it is...


My macbook pro mid 2010 2.4ghz with 4Go ram is very reactive, more more reactive than on Lion...


For example, i don't have seen the spotlight slowdown... or even safari slowdown, with lot of tabs open...

On my side, everything is nice now...


I don't have installed it on my Mac Pro, because i prefer to test it a bit more, but i think the nightmare is done now...

Jul 31, 2012 9:01 AM in response to dusanofrode

No it did not last, so I installed Mountain Lion 🙂 But guess what, it is as it was. Right now when I am writing this I already had the spinning ball twize...


Next stop will be a clean install og ML, but I already did that win Lion without any luck.


Had Macs since 1986 with NO PROBLEMS ever. Since I first time installed Lion last year I have been so unhappy and spent sooo much time on solving this.


My only hope has been that we are more guys out there in this club. I have freiends with MacBook Pros from 2009 with same problem, I have friends with iMacs and Mac minis with no problems ever (Lion).


After clean install of ML next stop is a new Mac. Cant do this any more 😟


If you do not have these problems, dont spend time on commenting.

If you are in same boat, may be you have some great ideas for us 🙂

For me, it was the "AddressBookSourceSync" eating up the memory. It's related to icloud syncing my contacts. Once I removed the contacts sync option from icloud it stops. You have to be careful to back it up and make sure you don't lose all your contacts.


I lost a few contacts in the process, but once I unsynced my contacts and deleted them from my macbook, then resynced with the icloud (I think they were still stored in my phone in a slightly different configuration), I haven't had a problem since then. I'll let you know if it recurs. Overall, I won't be too upset if this works, but I am a person who needs my computer stored info to survive in my job, not an IT person who lives to deal with this. I came to Apple because I don't llike dealing with this. If Apple continues to put out substandard and untested products like this that eat up my free time, I might as well go back to a PC.

Jul 31, 2012 11:13 AM in response to dusanofrode

About Address Book i don't know, because i use it only when i do a synchronisation with my iphone.

But for all others, have you done :

1 / Resetting the PRAM :

- Shutdown your mac (not reboot, shutdown it and wait 15 seconds after)

- Light your Mac and quick press simultaneously (Apple () + ALT + P + R) at boot, stay push instead you listen 3 boot boing sounds, and let it boot after the third boing

2 / If it persist, try to reset SMC : http://support.apple.com/kb/HT3964?viewlocale=en_US&locale=en_US

3/ Thing to do also (to try - but it give only a small boost) is to disable Secure Virtual Memory, it's an setting which as disabled by default in Snow Leopard, and all older systems, it eat cpu, but not much, it encrypt memory to avoid steal...

to do this you have to type something in the terminal more infos here (to disable it, and to re-enable it): http://hints.macworld.com/article.php?story=20110920052038951


hope it will help

here is another possible remedy:


I was suffering from the same problem, constant beachballs etc.


I checked the usual: spotlight, Diskutility, permissions, PRAM -- none of these solved the problem of a slow computer that was running very nicely under Snow Leopard.


yesterday I tried to follow the advice, preparing to install from scratch but something went wrong with the download.


in the meantime I ran the free tool Onyx to check on a few things (most everything that doesn't require you to quit the appstore app)


I think deleting corrupt preferences did the job, it might have been some other rebuilding.


In any case: going through the different tasks offered by Onyx seems to have fixed my machine. tocco ferro, or knock on wood.


Let's see how this cat treats me now...

Nov 13, 2012 1:51 PM in response to JWKanvik

An update.


After some updates from Apple (ML), now 10.8.2 it seems that everything is OK(!!!)


I haven't done anything other than the normal things I have been doing since last year, diskutility, reset here and there and so on. Since 10.8.2 it's been so stable 🙂


So it is clear to me what I expected in the first time that an OS X update last year "hit" some MacBook Pros. My guess is that they _have_ read our treads about sloooooow Lions and started to investigate.


I was blaming Seagate but now that I still can use the 500GB/SD disk with no problem I reedraw that...


So from here - a smile 🙂


Sorry again for my bad English

Update:


So Ive been subscribed to this for a while now and thought Id give an update on how Lion is still plaguing me with the beachball. Search my other posts for the history.


As mentioned before I installed 4Gig RAM, New Momentus XT HD 750Gb, fresh install of Lion. All good for a month or so or longer but the beachball returned....

As much as I would love to have Mountain Lion installed, Apple will not allow it on my Blackbook even though it could probably run it. i cant afford the price of a new Mac just to have my mac run the way its meant too. With Apple not admitting to any problem on older hardware its hard to see if we are going to see any solutions soon. very poor on Apples part but heres what Ive done.


I have Tech Tool Pro 6 and decided to run that to see if it would come up with any major issues. I created an edrive on a seperate drive and reboted into the eDrive and ran the Tech Tool program. It found a multitude of problems. Particularily a heavily fragmented drive. And I mean HEAVY! it took over 24hrs for its to run File optimizer, then Volume optimizer then Volume rebulder and after using for the day I have noticed not one Beachball.

Now whos to say that it will last but at least I have TT6 to carry out the required maintainence to get the drive back on track and stop hang ups. I may run it once a month just as a matter of course. It shouldnt take the 24hrs+ now like the initial scan and rebuild. I have checked that the Secure VRAM is on and it is but i dont have my RAM being eating up to the extent that it hangs. Ill update in another month or so. I would conclude though that even a fresh install of Lion is rather scattered and untidy and thus the beachball is appearing within days or weeks for some users.


i would love to go back to Snow Leoapard but Apple being Apple they have me so heavily involved with iCloud that I cant go back that easy!! Ive managed to keep the messages beta on my mac too even though the trial has finished and that has proved invaluable. Why cant Apple not make certain features available to those people that cannot upgrade to ML because Apple dont allow the hardware? At least make it a bit easier to be part of the crowd instead of rubbing Lion users noses in it and saying "Get a new Mac" that is a luxury that I simply cannot afford.


If I can sustain a stable Mac for the month then Ill know that TechTool6 made everything ok. And Apple dont actually stand by their software that much if it takes a 3rd party to make their OS run more efficiently.


Hope this helps others. Sure as **** Apple aint gonna help!

That's a silly call. I have never used Tech Tool Pro, Genius or any other 3rd party App to make my Mac run more efficiently. Disc utility on a well maintained Mac is ample. Apple stand by all their software. Just because you have issues on a very old computer doesn't mean that others do. I suppose Ford are pretty ignorant not allowing the T-Model to run on Unleaded Fuel either.


It's fine to stay with an old machine, just don't expect companies to stop advancing technology for your sake. You can still run an old system with old programs on an old machine. If you can't afford a new machine, then that is no one else's fault.


Good Luck


Pete
