Slow Mountain Lion and upside down scrolling
After updating to Mountain Lion my iMac is running extremely slowly.
Does anyone have any ideas on why or how to fix it?

can anyone tell me why I can no longer see the scroll bar to the right of the screen unless I stretch the screen but it fades in and out instead of always being there to scroll down
Open General preferences. Select the desired scrollbar behavior/appearance:

Hi folks,
I tried downloading the latest OS X Mountain Lion and [after a long time... I have a slow connection] I got an error message ... We could not complete your purchase The product distribution file could not be verified. It may be damaged or was not signed.
Everytime I retry or continue the download I just keep getting the same error message!!!
What can I do to get my product?
PMThe only thing that worked for me was to boot in safe mode.
Power down. Then press power button and hold 'shift' key until grey screen with progress bar appears... Once booted and logged in just open safari and browse to applestore.
No trouble at all once I did this.
Reminder: create full backup before you upgrade OS
Hope it helps. -
I download OSX mountain Lion and my mac is very slow.Any idea why?
After downloading mountain lion my mac gets slow...any idea why?
Try this:
Boot into Safe Mode then reboot normally. Do the following:
Repair the Hard Drive and Permissions - Lion/Mountain Lion
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported then click on the Repair Permissions button. When the process is completed, then quit DU and return to the main menu. Select Restart from the Apple menu.
Does this help? If not, then you should reinstall Mountain Lion:
Reinstalling Lion/Mountain Lion Without Erasing the Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed.

Wait until the operation completes, then quit DU and return to the main menu.
Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless. -
I updated my MacBook Pro with Mountain Lion and now it is slow in starting up and loads a number of probrams. How can I fix the problem?
Have you tried starting in Safe Mode and see if the slowness still occurs?
Restart holding the "shift" key.
(Expect it to take longer to start this way because it runs a directory check first.)
If this works look in System Preferences > Users & Groups > Login items and delete any third party login items (-), you can always add them back with the (+). Also look in /Library/Startup Items. Nothing is put in that folder by default, so anything in there is yours.
Reboot normally and test. -
I think I finished installing Mountain Lion, and am at the "log in" page with the Mountain Lion icon, but I cannot do any of the functions on screen. That is, I cannot log in, sleep, restart, or shut down. I am running it on an Early 2009 Macbook Pro, which is said to have the capabilities of running Mountain Lion.

...Is there any way I can install a partition that runs snow leopard on my early 2011 MB pro with what I have (new SSD, New RAM, Current version Lion running, no external drive, lack of original snow leopard disks [I lost them ] and the general 10.6.3 snow leopard boot disks)...
As the last post suggests, call Apple and order a replacement original disc for about $17. They will ask you the model and serial numbers.
Your retail version of Snow Leopard OS 10.6.3 will not work on that Mac as it requires a minimum of OS X 10.6.7 to boot and operate.
Another alternative is to again borrow another Mac to install your retail Snow Leopard into an external HD or partition, upgrade it to 10.6.8 and then clone it back to a partition on your MBP. -
Scroll malfunction with Mountain Lion and Mavericks after download
Since I downloaded Mountain Lion and now Mavericks the scroll function has stopped working. All other pad functions work but not scroll with 2 fingers. Anyone else solved the problem?
HI tmwfromuk,
Did experience exactly the same malfunction. Still did figure out why.
Will continue to figure why. When I have some news I will inform you on this.
Regards,
Ch. -

Open General preferences in System Preferences. You can set the desired scrollbar behavior there.

Mountain Lion and Lion very slow on Macbook 13' 2010 Middle
The problem is the Mountain Lion and Lion very very slow, but Snow Leopard was fast.
The Lion bit faster, the Mountain Lion is much slower.
Animations are choppy and slow, but sometimes fast, but mostly random stuttering. If i have multiple windows opened, the Misson Control is very slow and useless. I think the system UI framerate is low (about 10-15 FPS)
Overall, the system response is very slow, and lagging.
I tried to clean dinstall several times, but this didn't help me.
I know that the new system is slower on older machines, but it would not be so necessary. This Machine is good machine, and i think this is enought for Mountain Lion. Will Apple fix this slow issue soon (maybe 10.8.3), or stay in this state?
At current state of the system is unusable due to the slowness.
Or is it a non official solution to fix this?
Thanks for your answers.How much RAM do you have installed? 4 GB RAM is generally recommended as a reasonable minimum since kernel_task (part of system) consumes up to 1 GB; my browser consumes another 500 MB or so. So, if you like to multi-task and have several things open, then you will need to increase your RAM. This problem will not be fixed; I sent in a bug report and the reply was that this is how it is intended - 64 bit addressing consumes far more resources than 32 bit (Snow Leopard).
You'll need to look at your processes in Activity Monitor, quit some apps while working on others that are CPU intensive, and increase the RAM if possible. -
OSX Mountain Lion and Excel Scrolling
I just installed OSX Mountain Lion and now when I open a either a new or existing Excel spreadsheet the screen continuously scrolls to the right. Anyone know how to resolve this. I've restarted the machine several times and it still does it.
I see the spiraling nebula, Lion, elephant, grass, etc. pictures here in ML 10.8.2. If you have a folder of pictures, that contains one or more additional picture folders, ML will only image the top folder with screen saver. The types of slideshows have changed too.
Suggest you find someone running ML and take a look. -
Just downloaded Mountain Lion and want to remove natural scrolling; I went to system preferences, but I don't have a mouse. How can I get that to open to change the scrolling?

I upgraded my iMac to Mountain Lion and it has been painfully slow ever since. Any ideas on what might be happening and how to fix it?
First, back up all data immediately, as your boot drive might be failing.
There are a few other possible causes of generalized slow performance that you can rule out easily.
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.
Disconnect all non-essential wired peripherals and remove aftermarket expansion cards, if any.
Otherwise, take the steps below when you notice the slowdown.
Step 1
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 2
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. -
Tried to install update to Mountain Lion and get this message: OSXUpdCombo 10-1.8 image data corrupted.
Try booting into the Safe Mode. Shut down the computer and then power it back up. Immediately after hearing the startup chime, hold down the shift key and continue to hold it until the gray Apple icon and a progress bar appear. The boot up is significantly slower than normal. This will reset some caches, forces a directory check, and disables all startup and login items, among other things. If the system operates normally, there may be 3rd party applications which are causing a problem. Try deleting/disabling the third party applications after a restart. For each disable/delete, you will need to restart if you don't do them all at once. You can download from the Safe Mode.

Can I purchase Mountain Lion and make a flash drive bootable? I do not want to install it on my Macbook Pro. I have Snow Leopard on my Macbook Pro now, and due to my hard drive needing repair, I need to boot off of another source, like my flash drive. I am in Paris and my Snow Leopard DVD is in Texas.
Mac OS X has a built-in disk diagnostic and repair program called fsck or file system consistency check. Here’s how to verify and repair your startup disk with fsck. As soon as you hear the startup tone, press and hold Command-S on the keyboard. Keep holding down those keys until you see a black screen with white lettering. This is called “booting into Single User Mode.” As the Mac boots in this mode, the screen reports each step of the process. The line should end in root#. Right after the root# prompt, enter the following: /sbin/fsck -fy
If repairing the disk in single user mode fails, it means one of two things. Either your hard drive itself is failing (a hardware failure), or the directory damage on your hard drive is beyond the capability of the built-in repair procedures in OS X.

HT3529 Setting up signature line for iMessage
Can you set a default signature line in an iMessage? Many people I text do not know my incoming phone number and I'd rather not keep typing my name and title in an iMessage. Can someone tell me if this can be done?
