Slow after installing mountain lion

About month ago upgraded, gray screen, endless spinning wheels every color & shape, safe mode over & over, re-installed ML several times & it would freeze for DAYS in the process, force quit, repeat. So now for whatever reason, I got the computer on but it's very, ver, ver (did I say very?) slow. What do I do?

I ordered something from a website I haven't used before, and it was very slow, but I don't know if it's that website or safari. Safari is the only browser I use.

My macbook pro is very slow after installing mountain lion

my macbook pro is very slow after installing mountain lion? Is anyone else having this issue?

If you don't use an SSD and bump your RAM up to 8 Gb's you may experience slow speeds, but I noticed slow speeds with your general configuration in SL.
one thing you should consider right now is, Spotlight is Reindexing your hard drive, that takes time and resources, (resources which you don't necessarily have to spare).
If you continue feeling like your performance is slow, you have a few options with this computer (I have the same one).
the express card slot can house a wintec SSD drive. That little door on the side of your machine is pure gold for a really quick solution for speeding up your machine. I have one in mine right now i'm using as a scratch disk for CS6 but I used to boot from it, and the speed boost was out of this world.
You could take out the internal HDD and put in a new SSD (I have a Vertex 4 from OCZ) it is completely over kill but my experience is pretty fast and I keep up with the later MBP models colleagues have.
There are some other options for you like taking out the optical drive (however I don't know if I'm supposed to talk about that here). Google Data Doubler.
You need to also set it to always use the 9600 chipset, this will increase performance a lot too. to do this go to system preferences>energy saver>Better Performance. This switches the video card to the better one and makes a world of difference.
Lastly, your RAM. after an EFI Firmware update, our computer support up to 8GBs of RAM. Do it!

My wifi is very slow after installing mountain lion on my Mac book pro

My wifi is very very slow after installing mountain lion on my MacBook pro.
What can I do?

Ha ha, I misread that as "My wife is very slow after installing mountain lion on my Mac book pro"
BTW on my MBPro (late 2009 with max RAM) Mountain Lion runs very well with no slowing down.

HT1338 Why is my MacBook Pro running so slow after installing Mountain Lion 10.8.

Why is my MacBook Pro running so slow after installing Mountain Lion 10.8. I have restarted, created more free space on my hard drive and run disk utilities. Simple operations result 20 seconds or more of the spinning wheel. Some are so slow that the operation does not happen at all. Itunes music cuts out during operations.

Check out this article by Thomas Reed for help http://www.reedcorner.net/understanding-upgrade-nightmares/. Also, make sure all apps are compatible with Mountain Lion using www.roaringapps.com. Do you have any antivirus installed? Make sure all apps are updated as well.

Safari runs slow after installing mountain lion

Safari is running very slowly since I installed Mountain Lion. Any suggestions about why this is happening or how to improve the speed?

I ordered something from a website I haven't used before, and it was very slow, but I don't know if it's that website or safari. Safari is the only browser I use.

Help! Mac is super slow after installing mountain lion

Ever since I installed Mountain lion on my new imac everything seems to be working really slowly. iphoto takes about 5 minutes to start and once it has started up it is really slow. Same thing happens with itunes. I have repaired disk permisions many times and also have run my Mac Keeper program as well.None of these things seem to help and it seems to be getting worse. Has anybody else have this trouble? Any ideas would really be appreciated. Thanks

Why is my MacBook Pro very slow after installing Mountain Lion 10.8.5. - Solutions?

Hello, hello
After waiting quite a while - I paid the relatively small amount, and got myselves a new OS.
But I am very disappointed of the speed - I see that this also was a problem with OS Lion?
Please assist me. Perhaps others have this problem as well?
Some info:
- 2,66 GHz Intel Core i7 processor
- 4 GB 1067 MHz DDR3
Also
- Sometimes I run the Parallels Desktop 6 and 9 software, does this affect specs of the new OS?
Hope to hear from you guys.
Sincerely,
Harald

With only 4GB of RAM, how much do you have devoted to the virtual machine running under Parallels? Even if it's a small amount, it's going to make page outs and swaps used very high. From my perspective, 8GB of RAM is the 'sweet spot' for running Mountain Lion.
I'm assuming that you've a 15" mid-2010 MacBook Pro? If so, you can speed things up by installing the maximum 8GB of RAM. Go RAM shopping at Crucial or OWC.
Other than upgrading your RAM, the only thing that you can do to speed up your machine is to install a SSD. You can also check the SSDs at Crucial and OWC and decide if one is right for you.

Hi All,
Is anyone else experiencing the same issues, since I have updated to Mountain Lion last week my mac is now running alot slower than before on startup, closing down and when opening and shutting programs / apps.

Outlook (MS Office for MAC2011) appears to be using up to 67% of my CPU time even when I'm doing nothing. Also, immediately after installing Mountain Lion, log-ins to the OS and normal operations noticeably slowed. Suggestions?

After installing Mountain Lion, I experienced a noticeable reduction in performance. When I log-in, I must wait several seconds for the cursor to become effective in the log-in window. When I come out of standby mode, I have the same issue. Also, when looking at cpu usage, Outlook appears to be using up to 67% of cpu when not doing anything. I'm not happy with this result.
Does anyone have suggestions as to how to fix?

Uninstall Office and reinstall it
Use these instructions to do it and do not omit any of them.

TS3147 After installing Mountain Lion, I tried to scan from my Canon MX870 and received the message: "MP Navigator EX quit unexpectedly. Click Reopen to open the application again. A report will be sent to Apple,"

After installing Mountain Lion, I tried to scan from my Canon MX870 and received the message: "MP Navigator EX quit unexpectedly. Click Reopen to open the application again. A report will be sent to Apple," This problem happened right after I installed Mountain Lion. I then downloaded Canon's upgraded software and drivers for the MX 870 and the problem was resolved. Now one month later, the problem has returned.

Solved problem with original Canon software. When I downloaded Canon software upgraded for OS X 10.8, I got all by Navigator Ex. Noticed that on Canon's site, the upgraded version is 3.1; my app was 2.1. Upgraded to 3.1 for Nav. Ex, and it works.
You should still use Image Capture IMHO. If it was my gear, that's what I would do. No need to worry about software upgrades.

Numbers does not open with the main user after installing mountain lion. It works flawlessly when I use the second account on my mac. What got corrupted in the admin-account, something in the user-library? How can I fix it? I´m kinda desperate...

Numbers does not open with the main user after installing mountain lion. It works flawlessly when I use the second account on my mac. What got corrupted in the admin-account, something in the user-library? How can I fix it? I´m kinda desperate... (the same happens with the other iWork-Apps!)
Looking forward to hearing from somebody with a littlemore expertise than me, Chris

you can remove preferences files by navigating to the Preferences folder for your user as follows:
0) Quit ALL iWork apps (Keynote, Pages and Numbers)
1) from the Finder select the menu item "Go > Go To Folder…". This will bring up a dialog:
2) enter the path "~/Library/Preferences" (no double quotes)
3) find the files:
com.apple.iWork.Keynote.plist
com.apple.iWork.Numbers.plist
com.apple.iWork.Pages.plist
and move these to the trash. I would NOT empty until later.
4) restart Numbers

Ive just upgraded my late 2009 macbook, and things are not working properly. First of all, when I started the computer first time after installing Mountain Lion, some message advised me that some files were impossible to install.

Ive just upgraded my late 2009 macbook, and things are not working properly. First of all, when I started the computer first time after installing Mountain Lion, some message advised me that some files were impossible to install. Once I wrote my password, and for now on, everytime I start the session, another window advise me that "Java SE 6" is missing, due that, the computer can't run some "CS5Service Manager". If I try to install it, the download ends with an error. If finally, you skip the istallation, you arrive to the dock, but the menu bar at the top of the screen doesn't show up.
In addition, my trackpad doesn't works either. I can move the arrow but i can't click anywhere, probably because the option of clicking by touching is disabeled and I can't performance a regular click.
I'll be very glad if someone know what the heck is happening with my computer. Anyway, I'm going to the genius bar next Saturday. Thx!

We're sorry.

Can No Longer Get Camera Photos After Installing Mountain Lion

After installing Mountain Lion, I am no longer am able to see pictures from my digital camera thru the USB port. This camera has worked for years with my iMac, but not anymore. Anybody else having this issue after installing the newest system?
Dick

Paul_31:
I have not tried to import the photos directly into iPhoto. However, I did remove the SD card from the camera and plug it into a USB card reader, and my iMac would NOT read the photos that way either. I took the camera and plugged it into my Win. 7 laptop and the pictures showed up nicely, so I know the camera and the card are Ok. My iMac has been working strangely since I installed Mountain Lion. I'm getting lockups using iMovie too.
