MacBook Pro runs slow after Mountain Lion installation

I have a mid-2009 13" MacBook Pro with 2.2g Ghz processor, 2 GB of RAM and 160 GB encrypted disc.
After installing Mountain Lion and the recent upgrade OS X 10.8.1 (12B19), the system runs noticibly slower than with Lion, which ran slower than the previous version. This shows up in opening and closing programs, rate that drop down windows appear when something is clicked on the task bar, rate that windows open and close, rate that the dock comes up and the icons expand when the curser is moved over them, etc.
Due to my type of work, I need to encrypt the disc. I know this is costing me some speed. I unencrypted the disc and it ran noticably faster, and when I re-encrypted it seemed to run faster than before unencrptying and re-encripting. I have repaired permissions and verified the disk OK.
Somewhere in the build up to Mountain Lion release I thought I read where 4 GB of ram was recomended for Mountain Lion, allthough now the specs indicate 2 GB is OK. In activity monitor, the pie chart for system memory seems to always remain less than about 40% of active memory (yellow).
What recomendations does the community have to increase the speed of operations back to when this system was new?

I was having the exact same problem. My MacBook Pro was seriously close to unusable how slow it was. On a different thread, someone recommended I reset the VRAM and PVRAM (not sure about those initials). Shut down computer. Rebooted while holding down Command-Option-P-R all at the same time until I heard the second startup tone and then released. I noticed an improvement in performance immediately.

Macbook Pro runs slow using Mountain Lion?

I have access to use a Macbook Pro which is running Mountain Lion. However, the MBP runs very slowly and the coloured wheel is constantly spinning with almost everything I try to do. I do not know why and would like to be able to have a normal running MBP.
I wondered whether installing Yosemite might help? Or I have read some posts about resetting the System Management Controller. Please can someone give me some advice as to what to do that will work?
Thank you

Installing Yosemite will probably NOT help.
Slow MBPs usually are a result of a failing HDD, third party software (often so called 'cleaning' or 'performance' applications) or unnecessary AV software.
SMC resets are good for certain hardware issues and will also probably NOT address the issue.

Why is my macbook pro running slow with mountain lion?

After installing Mountain Lion, I find navigating, opening programs, etc. is taking more time, why is this?

Immediately after installing Mountain Lion, your system will be rebuilding the Spotlight index. This should only take a couple of hours at most. If the problem persists you can run diagnostics. I just happen to have written a little diagnostic program recently. Download EtreCheck from http://www.etresoft.com/download/EtreCheck.zip, run it, and paste the results here.

Why is my MacBook Pro running hot after mountain lion upgrade?

The fan is on high all the time and the system is running very hot. It also consumes the battery way faster than it used to.

Thanks for your links. My MacBook fan was running constantly from switch on and the underside was getting very hot. Using your first link, I followed the Activity Monitor instructions and found that Dashboard was using '117%'. As soon as I closed it down the fan instantly slowed and after only a few seconds switched off..
Thanks again..

Spotlight may be indexing your drive(s). Click the Spotlight icon at the right of your menubar; if it shows things being indexed, that's at least some of the reason.

MacBook Pro running slow after USB flash drive

I mount a Kingston USB flash drive to my 30 days old MacBook Pro running Lion 10.7.4

But after that USB flash drive it went slow, I thought it was and error and reebot it, also cleaning out the Cache and other stuff with CleanMyMac.
But it continues to run slow.
Please if someone knows what I can do I will appreciate it.

Why is my macbook pro running slow after os x yosemite upgrade

Why is my macbook pro running so slow after os x yosemite upgrade

Please describe the problem in as much relevant detail as possible. The better your description, the better the chance of a solution.
For example, if the computer is slow, which specific actions are slow? Is it slow all the time, or only sometimes? What other changes did you make, if any, just before it became slow? Have you seen any alerts or error messages? Have you done anything to try to fix it? Most importantly, do you have a current backup of all data? If the answer to the last question is "no," back up now. Ask if you need guidance. Do nothing else until you have a backup.

My macbook pro runs slow after install of lion

i was wondering if anyone is having any issues after installing lion and doing the 10.7.3 update? i noticed a slow performance after i did the update. i also added 8 gigs of memory hoping this would help, but it didnt i also formatted the drive install snow leo and my boot time was 2 minutes i upgraded to lion and my boot time jumps to 6 plus minutes. i have run the disk permission finds some problems then repair but still my macbook runs slow HELP ME!!!!!

Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, press the key combination shift-command-U. The application is in the folder that opens.
☞ If you’re running Mac OS X 10.7 or later, open LaunchPad. Click Utilities, then Console in the page that opens.
Step 1
Select "system.log" from the file list. Enter "BOOT_TIME" (without the quotes) in the search box. Note the times of the log messages referring to boot times. Now clear the search box and scroll back in the log to the time of the most recent boot when you had the problem. Post the messages logged during the time when you had the problem – the text, please, not a screenshot. For example, if the problem is a slow startup taking three minutes, post the messages timestamped within three minutes after the boot time. If the problem is a crash or a shutdown hang, post the messages from before the boot time, when the system was about to crash or was failing to shut down.
Edit out excessive repeats and personal information, if any.
If the log doesn't go back far enough in time, scroll down in the Console file list to /private/var/log/system.log.0.bz2. Search the archived log, and if necessary the older ones below them, for the same information.
Step 2
Do the same with kernel.log.
Step 3
Still in Console, look under System Diagnostic Reports for crash or panic logs, and post the most recent one, if any. For privacy’s sake, I suggest you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if present (it may not be.) Please do not post shutdownStall or hang logs – they're very long and not helpful.

Macbook running slow after mountain lion update

why? i have 2 gb of RAM, that should be more than enough, right?
firefox is running slow, everything is freezing. i have barely used any of my hard drive space with it being at 225.61 gb free out of 249.2 gb.
its really frustrating.....

Two gb is the bare minimum for running Mountain Lion.
The model 7,1 (Mid 2010, White Unibody) can use 8gb of 204 pin 1066mhz PC3-8500 RAM
These are good online stores for Mac compatible RAM
OWC http://eshop.macsales.com/shop/memory/Apple_MacBook_MacBook_Pro/Upgrade/DDR3_Whi te - They offer Mac tested RAM at very good prices.
Crucial Memory http://www.crucial.com/ - good place to buy RAM from all over the world. They also have an excellent memory selector that allows you to choose memory based on your computer's model
Data Memory Systems http://www.datamemorysystems.com/apple-memory.asp - another good, cheap place to buying RAM if you live in the U.S.
Here are video instructions on replacing the RAM on the White Unibody.

IMac-27inch model (late 2012) running slow after Mountain Lion 10.8.5 supplemental update

I have the iMac 27-inch (late 2012 model), 8GB RAM, 1TB Hard Drive. All of a sudden after the Mountain Lion 10.8.5 Supplemental update it started running like molasses (apps take forever to open, takes forever to wake out of sleep, long boot up times, etc.) I ran verify disk, verify disk permissions, etc. I found that when I ran verify disk permissions, it stated that the iTunes permissions weren't right so I repaired disk permissions, reboot, still same problem. Ran verify disk permissions again, once again iTunes permissions issues, repair disk permissions, restart, same problem over and over again like Ground Hog Day, please help...

First, back up all data immediately, as your boot drive might be failing.
Step 1
This diagnostic procedure will query the log for messages that may indicate a system issue. It changes nothing, and therefore will not, in itself, solve your problem.
If you have more than one user account, these instructions must be carried out as an administrator. I've tested them only with the Safari web browser. If you use another browser, they may not work as described.
Triple-click anywhere in the line below on this page to select it:
syslog -k Sender kernel -k Message CReq 'Channel t|GPU D|I/O|find tok|n Cause: -' | tail | open -ef
Copy the selected text to the Clipboard (command-C).
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Paste into the Terminal window (command-V).
The command may take a noticeable amount of time to run. Wait for a new line ending in a dollar sign (“$”) to appear.
A TextEdit window will open with the output of the command. Normally the command will produce no output, and the window will be empty. If the TextEdit window (not the Terminal window) has anything in it, stop here and post it — the text, please, not a screenshot. The title of the TextEdit window doesn't matter, and you don't need to post that.
Step 2
There are a few other possible causes of generalized slow performance that you can rule out easily.
Reset the System Management Controller.
If you have a portable computer, check the cycle count of the battery. It may be due for replacement.
If you have many image or video files on the Desktop with preview icons, move them to another folder.
If applicable, uncheck all boxes in the iCloud preference pane. See whether there's any change.
Disconnect all non-essential wired peripherals and remove aftermarket expansion cards, if any.
Check your keychains in Keychain Access for excessively duplicated items.
Boot into Recovery mode, launch Disk Utility, and run Repair Disk.
If you're booting from an aftermarket SSD, see whether there's a firmware update for it.
If you have a MacBook Pro with dual graphics, disable automatic graphics switching in the Energy Saverpreference pane for better performance at the cost of shorter battery life.
Step 3
When you notice the problem, launch the Activity Monitor application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Activity Monitor in the icon grid.
Select the CPU tab of the Activity Monitor window.
Select All Processes from the menu in the toolbar, if not already selected.
Click the heading of the % CPU column in the process table to sort the entries by CPU usage. You may have to click it twice to get the highest value at the top. What is it, and what is the process? Also post the values for % User, % System, and % Idle at the bottom of the window.
Select the System Memory tab. What values are shown in the bottom part of the window for Page outs and Swap used?
Next, select the Disk Activity tab. Post the approximate values shown for Reads in/sec and Writes out/sec (not Reads in and Writes out.)
Step 4
If you have more than one user account, you must be logged in as an administrator to carry out this step.
Launch the Console application in the same way you launched Activity Monitor. Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
View ▹ Show Log List
from the menu bar.
Select the 50 or so most recent entries in the log. Copy them to the Clipboard (command-C). Paste into a reply to this message (command-V). You're looking for entries at the end of the log, not at the beginning.
When posting a log extract, be selective. Don't post more than is requested.
Please do not indiscriminately dump thousands of lines from the log into this discussion.
Important: Some personal information, such as your name, may appear in the log. Anonymize before posting. That should be easy to do if your extract is not too long.

Macbook Pro runs slow after upgrade

I have just upgraded to Mountain Lion 10.8.3 (from 10.6.8) on my 2011 i7 Macbook Pro.
My computer now runs slower than ever. Boot up takes forever. Shut down takes for ever. I get constant beach ball.
I am shocked at how horrible this OS is and though there are some "nifty" features, it runs so poorly It's hard to enjoy them.
So my question is, is this a common issue with Mountain Lion or is it a coincidence and perhaps something is wrong with my computer?
Thanks!

MacBook Pro running hot after Mt. Lion upgrade

MacBook Pro mid-2009 2.53 with 8GB RAM and 750GB 7200 rpm harddrive: CPU seems to be running much hotter (>70 degrees C) and fan is the normal 2000 rpm per iStat after upgrading to Mt. Lion 10.8.1 and 10.8.2. Bottom of laptop near center screen side is the hottest area. Any ideas why? Or how to cool it off again to the way it was before the upgrade from Lion?
Thanks.

Mac running slow after mountain lion

Mac startted running slower about a week after downloading Mountain Lion. Is that possible related?

Probably not but you haven't said anything about your system configuration so that may have a bearing on things. How much RAM is installed on your machine? If you have the 2GB minimum then you almost certainly could benefit by a RAM upgrade. Please complete your profile so we know a bit more about your system, it won't help on this thread because the thread has already begun however it will be useful down the road. For instructions on how please click Profile Update.
Another thing you can do is open Disk Utility (Applications - Utilities - Disk Utility) and run Repair Disk Permissions, I'd recommend doing that at least 2X.

Macbook pro runs slow after sleep mode.

This issue has bothered me for a long time already.
And because of this, I have re-installed the OS many times.
But apparently, re-installing the OS does not help.
The machine will runs slow again after a certain period of time.
So, here is my problem.
When you do the four finger down swipe, there will be a zooming out effect, right?
(The same function as pressing F3, which let you knows how many applications you have opened)
This zooming out effect is smooth when I first bought my Macbook Pro.
It is smooth too after I re-install the OS.
But now, after a period of time, this effect becomes so choppy and slow.
As I mentioned above, I tried re-installing the OS. It works, but only works for a few days.
And then it becomes choppy again.
The only solution is to reboot my machine.
Can anyone suggest me what to do?
I guess I have to re-install the OS again tonight... LOL

Try using Disk Utility to do a Disk Repair, as shown in this link, while booted up on your install disk instead of re-installing.
You could have some directory corruption. Let us know what errors Disk Utility reports and if DU was able to repair them. Disk Utility's Disk Repair is not perfect and may not find or repair all directory issues. A stronger utility may be required to finish the job.
After that Repair Permissions.
No need to report Permissions errors....we all get them.
