Slow macbook pro since Mountain lion

Yes this can be the case, even slow shutdowns and startups. But Hardisk space can also be a factor. Anything below the 10Gig mark of space left can cause extreme slowdowns.

the other is Fonts.. if you use them alot.. check your fonts in fontbook anything above 300 fonts active will slow down your system. you should only turn them on when you need them for a certain jobs. De default font set is 176 fonts

last tip would be PRAM and VRAM

Resetting PRAM and NVRAM

1. Shut down the computer.
2. Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
3. Turn on the computer.
4. Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
5. Hold the keys down until the computer restarts and you hear the startup sound for the second time.
6. Release the keys.

Your computer's PRAM and the NVRAM are reset to the default values. The clock settings may be reset to a default date on some models.

Hope it helps,

If this has sloved your problem please mark it as Solved thank you..

Your system has a lot of internal work to do after the install, including reindexing all your files... Patience..

I did all that and im having the same issues,. it didnt help.

You can try to repair the disk from the Disk Utility program in the Recovery HD

Aren't we forgetting something here? I didn't buy the upgrade so that I could have days of fun searching the web to find out all of the secret things that I - the customer - must do to make the upragde worthwhile. I bought it because Apple told me that it would be worthwhile.

And if I was going to have to suffer a machine that can hardly walk any more, let alone run, and that was Apple's design, then that is what they should have told me, rather than telling me it would be seamless.

And how do I know for sure that these issues are caused by file indexing? Especially since I had switched file indexing OFF prior to the upgrade. Was this yet another setting/preference that Apple decided to completely ignore during the upgrade? If so... then TELL me that is what you are doing - better still DON'T do it because I set those preferences for a good reason.

No..... this is NOT the way to do upgrades - even those folks in Redmond learned this years ago.

I have noticed that booting my macbook pro after a shut down since upgrading to Mountain Lion is taking over a minute as compared to about 30 seconds with OSX Lion. Has anyone else noticed this and does anyone have any suggestions? I have reset the PRAM and the SMC, I have verified disk (no problems), verified permissions (no problems). I read in the forums that Spotlight can take days of reindexing after the upgrade, but mine completed the reindexing within a couple of hours. Any help is appreciated. Thanks.

Yes... Ia m having similar problems. It's taking almost 70 seconds to wake up from sleep. And with Snow Leopard I didn;t have to worry about telling it that it had gone to sleep with two monitors - it remembered when it woke up. Now it just assumes that just the MBP screen is being used and I have to switch the attached monitor on and off to trigger it detecting two monitors are attached.

Then setting up the two monitors is taking approximately twice as long as it used to.

Hope this helps :-)

Hello, I am having same problems. After I got new macbook Pro on first week of July sometime it show spinning wheel for 20-30 seconds before the website is loading sometime on other apps too. That wasn't normal. I did a Disk Utility and it didn't help. I just installed Mountain Lion it did same thing. But other than that it works fine.

My Mac Min with Snow Leopard done this but I found it to be with my Internet connection. Adjust MTU setting to 1300 in advanced network setting and that resolved my problem. Don't know if you are having the same problem, but I would give that a try. Most of the time if you get the spinners in Safari it's because all the data has not loaded to the page and it's looking for something else to load. You Internet connection can cause this problem.

btw, I forget to post that I use the Google Chrome. I am going try change MTU setting to 1300 it were set to Automaticily.

well, mine is macbook pro (early 2011). So, it's older than yours. However, it works fine even after installing the osx ml..

Man, do you have Sophos antivirus? If that so, you need to uninstall it the right way:

1. For Sophos Anti-Virus for Mac OS X version 7.x , go to Macintosh HD|Library|Sophos Anti-Virus.
2. Select 'Remove Sophos Anti-Virus.pkg'.
3. Follow the instructions on the screen.

NOTE, if you are running Sophos Anti-Virus for Mac OS X version 4.x, the path in step 1 is Macintosh HD|Library|Application Support|Sophos Anti-Virus.

It seems that Sophos antivirus is crashing ML. They have an update but I'll wait some time becuase I've really had a painful time these days.

Yes, I have VirusBarrier but it does support Mountain Lion.

Update: Yesterday, I booted into safe mode, verified disk & verified permissions. Then I rebooted into norrmal mode and reset PRAM and SMC. Following that, I redownloaded and reinstalled Mountain Lion. This time, the installation was much faster and to my surprise, my MacBook Pro is running quite a bit faster. The boot up time is still slightly longer that Lion, but a vast improvement over yesterday morning. No lengthy reindexing and no system update required from App store.

I hope this helps with other peoples' problems.
