Can I uninstall Mountain Lion? It's VERY SLOW!

I installed the Mountain Lion OS 10.8.2 and have nothing but slow slow slow page loading and slow painting of photos. It was bad enough that I lost my calendar data but the slow operating system drives me nuts. If I wanted slow I could've kept a pc. Any advice? Can I get rid of this OS and get the old one back, please?

You are right, Thomas A. Reed.
It appears that my speed problem was not with Mountain Lion but was with my (new) wireless router. (The old one had died.)
Now that I'm connected via an ethernet cable, my speed is WAY faster. When I go to my next one-to-one appointment I'll get an Apple wireless router -- perhaps one with an external hard drive to use with Time Machine.
Thank you!

Mountain lion download is very slow and in-between it hangs of and starts from beginning. Is there a solution i have already purchased it can i download a torrent and authorize it

Mountain lion download is very slow and in-between it hangs of and starts from beginning. Is there a solution I have already purchased it can I download a torrent and authorize it. Somebody pl. Help

Exactly. Some of us don't understand the situation in India. This is a country with sickest internet speeds. The internet segment is dominated by fraudulant companies. There is no consistency that is why most of the data transfer here is through Pen drives and torrent websites. We have never seen a good downlooad speed here. And on the top of inconsistency lies the Mac book Air without a built in RJ45 port.
If i have to do it in an internet cafe it will cost me more time and money than to purchase a Mac book air itself. Apple should start giving us software loaded flash drives at least at premium.

How can I uninstall Mountain Lion?

Unfortunately, I've downloaded and installed ML yesterday and now my safari is very slow in opening pages and I can not open iPhoto. I wish to revert back to the Lion OS.

There is an update to iPhoto in the App Store and and here: http://support.apple.com/kb/DL1562. There a number of reasons Safari might be sluggish. Are you running Anti-virus software? What extensions if ant are you running. What plugins have you added to safari if any?

Can I uninstall mountain lion without loosing the content on my hard drive?

I hae just installed mountain lion and now I can not use my Adobe programs - note saying it can not run power PC programs. I am on a deadline and I MUST get back to the files I was working on before I did this.
I need to know if I can unistall without loosing all the files I was working on before.

Hi Cate,
Like John says , it is better to upgrade to latest Adobe as they are 64Bit based so they would perform much better on your Mac.
It can make proper use of your RAMS and graphic card.
good luck..

My Mountain Lion OSX is very slow and some of my applications get hang and also shutting down is slow

Open Console.app by clicking on Spotlight in the top-right of the screen and typing 'Console', then press 'return.
Look in the sidebar under 'FILES' for 'System Log' and click on it.
Click the 'Clear Display' icon in the taskbar, and then 'Insert Marker'. Make a note of the time on the marker.
Press the power button once to display the shutdown window. Make sure 'Reopen Windows when logging back in' is selected. Shutdown the computer (not 'Restart').
When the computer is off, press the power button again and log in. The Console window should be at the front of your screen. Skim through the messages and look for any obvious hangs or repeated messages.

After mountain lion install mac very slow

After Mountain Lion install, my MacBookPro mid-2009 version is extremely slow. What could be causing it to slow down ?

There are a bunch of threads about this. Use the search function and see what others are finding out.

How can I uninstall Mountain Lion and go back Lion?

I have tried everything. My MacBook Pro is just not the same since ML. I want to get rid of it and go back Lion. What is the easiest way to do so?

Clearing cache is a poor thing to do to improve system performance.
In fact, when you clear cache you actually slow your system down until cache is reloading again.
Yes, it is true cache can get corrupt and have to be cleared. This happens so infrequently that it is almost never a required solution unless you have problems that are specific to corrupt cache.
By the way why are you replying to my post when in fact your comments have nothing to do with my post at all.

Uninstall mountain lion and reinstall lion

how can i uninstall mountain lion and reinstall lion please i have no disks

https://discussions.apple.com/docs/DOC-1948

My iMac goes to disc utilities on startup, repair disk doesn't cure it and I can't reinstall Mountain Lion because I don't remember my I'd and password at the time I bought the software. Currently working abroad and at a loss can anyone help please?

My iMac goes to disc utilities on startup, repair disk doesn't cure it and I can't reinstall Mountain Lion because I don't remember my ID and password at the time I bought the software the system isn't accepting my current details and Apple isn't recognising the answers to my security questions. They don't even seem to have my correc date of birth so I can't progress the reinstallation. I'm currently abroad and have my iMac with me but with no way of contacting Apple that I can find, I'm at a loss and very reluctant to pay £35 to try and get my ID and pasword sorted out given that their system recognises my current details. can anyone help please?

when they gifted me the mountain Lion software several years ago.
Mountain Lion was introduced in July 2012. Did the people who gifted you possibly use their Apple ID for the purchase of your OS? If you used your own Apple ID, you should have simply used the one you use for all things app store. The problem with any purchase at the app store is: whatever Apple ID was used to purchase, it willl stay tied to that Apple ID forever. And, purchases from the app store are not transferable.
So, you can check with the person(s) who gifted you or spend $20 to buy it - or, if your hardware is compatible with the new OS Mavericks, you could download it and associate it with your Apple ID.
FWIW, according to the licensing agreement, the OS remains the property of Apple and you are only granted a license to run it.

How do uninstall Mountain Lion OS

How do I uninstall Mountain Lion and go back to Snow Leopard

Downgrade Lion/Mountain Lion to Snow Leopard
1. Boot from your Snow Leopard Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
4. Quit DU and return to the installer. Install Snow Leopard.
This will erase the whole drive so be sure to backup your files if you don't have a backup already. If you have performed a TM backup using Lion be aware that you cannot restore from that backup in Snow Leopard (see below.) I suggest you make a separate backup using Carbon Copy Cloner 3.4.1.
If you have Snow Leopard Time Machine backups, do a full system restore per #14 in Time Machine - Frequently Asked Questions. If you have subsequent backups from Lion, you can restore newer items selectively, via the "Star Wars" display, per #15 there, but be careful; some Snow Leopard apps may not work with the Lion files.

How can I reinstall Mountain Lion on new hard drive?

I've had to install a new hard drive as old one was failing.
Have loaded Snow Leopard from disc onto the new drive but can't install Mountain Lion which I was running prior to drive failure; very frustrated.
Have tried several options.
1. Tried to reboot from OS X Utilities but whenever I restart, holding the cmd + R keys, I can only ever get the standard screen. I've tried pressing keys early in restart, later in restart, keys on either side of the keyboard, cmd + alt/option + R but still can't get to the OS X Utilities.
2. Having given up on 1 I've tried to download ML from my purchase history in iTunes. I can see the purchase recorded but there appears to be no way to get to a reload option - at least not in the iTunes loaded from Snow Leopard
3. I tried downloading ML updates, hoping that might allow me to bypass 1 and 2. The download wasn't recognised by my machine.
4. I've be willing to just buy the **** OS again from scratch but iTunes won't allow me to do that either, at least not using my current Apple ID.
Does anyone have any bright ideas? I hate bloody computers.

Do you have any suggestions why I can't open OS X Utilities.
Thanks,

How old is your Mac, if it came with 10.6 installed it is too old to have Internet Recovery (command-option-R) And as it has a new hard drive you won't be able to use Recovery (command-R) either until a new copy of Mountain Lion is installed and ceates a recovery partition on the drive.

Can I get mountain lion on disc

Can I buy Mountain Lion on disc?

Hi
Restart or start up your mac and hold down Command + R keys
Cheers
Incidently, you can create a bootable Mountain Lion USB Installer from the Installer you purchased and downloaded from the Mac App Store, if you haven't already installed the OS, after which the installer will disappear, but you can always re-download the installer again.
Having a USB installer saves you the time to re-download the OS installer, if you want to install on another mac, and also lets you boot from the USB installer.
Here's how:
1. Downloading/Re-downloading the installer
http://www.macworld.com/article/1167855/installing_mountain_lion_what_you_need_t o_know.html
2. Creating a bootable installer
http://www.macworld.com/article/1167857/how_to_make_a_bootable_mountain_lion_ins tall_drive.html
It is very good advice to keep a USB installer at hand whenever and wherever you need it.

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.

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.

I recently purchased an iMac from a friend who factory reset it, and now I can't reinstall Mountain Lion?

     As the title says, I can't reinstall Mountain Lion. When I turn on the iMac, it send me straight to OX X Utilities. When I click on Reinstall Mountain Lion, it asks for my ID, but then states I did not purchase Mountain Lion. How do I fix this issue? I've tried asking Apple Support, but to no avail. I don't think the guy I spoke with understood what was going on.
I cannot get around OS X Utilities. There are only four options for me.
Reinstall Mountain Lion
Back Up (tried, nothing comes up)
Get Help Online (which is what I'm doing here)
Erase or Restore Utilities (I've checked this, it says my disks are not malfunctioning)
     My friend suggested signing into his ID to reinstall but when we did, it also said this ID has not purchased Mountain Lion. We logged into Apple Support went to registed devices and there was nothing there. I think he may have used another ID which is he searching for the info for. If we get the right ID, then maybe it will let us sign in on his name and reinstall Mountain Lion. But if he can't, or Apple won't take his ID, then I'm at a loss for options.
     So now I'm here, hoping someone else who bought a used iMac from a friend who factory reset it and needs info on how to reinstall Mountain Lion can help me. I don't know what else to do. If I can't get this thing sorted out, I'll have to drive to the apple store. The closest one is 60 miles away, so I'm not looking forward to that. Is that my only option now? What can I do?
tl;dr I bought a used iMac from a friend who factory reset it, and now I don't know how to reinstall Mountain Lion. What are my options?

If the system didn't ship with Mountain Lion originally and you didn't purchase Mountain Lion yourself, then you will need to purchase. A purchase by the system's original owner cannot be transferred to you.
Unless you have another system on which you have purchased Mountain Lion, you will need to first install Mac OS X 10.6.8 on the iMac, for which you'll need either the original installation disks, if the iMac came with 10.6, or a retail copy of 10.6. Install 10.6 and upgrade to at least 10.6.6, and then you can buy Mountain Lion from the Mac App Store, presuming of course that the imac can support Mountain Lion. See:
