Mountain Lion Locking Up

Hi
I'm having an issue with 10.8.2 (well since 10.8 onwards) where the OS just locks up a couple of times a day. I can move the mouse (as the beachball), bring the dock up, but I can't actually open anything, eventaully the dock sticks in the up position and this is normally where I hold down the power button to switch off, as I can't select the usual shutdown. While this is happening I also can't bring up force quite or the activity monitor, so I'm not really sure how I go about finding out which software is to blame.
I'm also noticing a general slowness... system prefs takes anout 20secs to open up, switching between programs often brings up a beachball. I have pleantly of ram in both my mac pro (16GB) and macbook pro (8GB), but it still happens on both machines.
I use Thunderbird and sometimes this freezes a lot... but how do I go about finding if it is the issue. Some of the other programs I use are;
Adobe CS6
Coda 2
Dropbox
Skype
LittleIpsum
OpenOffice
If anyone has any suggestions on how I can figure out the issue, please let me know.
Thanks
Wayne

Are there any more details you can provide? I would have included the following if I were asking the question:
iMac model (e.g. early 2008)
Amount of RAM memory installed
A detailed description of "lockup" (e.g. "It locks up every time I launch iPhoto") and whether it's consistent or sporadic.
If this iMac has multiple accounts, does it happen with all of them?
What I've already tried to correct the issue
Of course, there may be folks here with better telepathy skills than I possess.

Mountain Lion locks up after sleep, mouse is frozen on screen, requires hard reboot with power button

I have a 2007 Core 2 Duo 2.4ghz macbook pro with Intel 320 160gb SSD installed, and 6GB of Patriot RAM. Machine was working perfectly under Snow Leopard, NO ISSUES AT ALL FOR MONTHS!
After installing Mountain Lion the computer frequently locks up, requiring a hard reset holding down the power button.
The lock ups occur about 10-90 seconds after waking the computer from sleep. Everything will appear normal, i can click through some appliations, start typing somewhere, reading an article, or start watch the ipad mini launch video on apple.com, doesn't matter. Then all of a sudden the computer is just completely locked up. Nothing on screen is working, the mouse isn't even moving the system is completely locked up, and does not recover even if left for several hours. I have checked the logs and there's no sign of a kernel panic.
I have tried creating a new blank user profile, reinstalling from the recovery partition, and the issue persists. I've basically stopped closing my computer when i can avoid it, and the rest of the time i have about a %50 chance that i'll be able to work when i open my computer instead of having to do a hard reset.

With the 2007 macbookpro the optical bay was IDE. One of the upgrades i had made was an IDE to SATA adapter that held another sata hard drive in place of the optical drive(which had died). Even though this setup worked flawlessly under snow leopard, the IDE to SATA adapter seemed to be causing some issues with moutain lion when resuming from sleep. After removing the adapter and second hard drive, i have not had the computer lock up on me since.

Mountain Lion locks up during iTunes Airplay

Mountain Lion (10.8.0) - MacBook Retina - Clean Install (Not upgraded)
While using Airplay in iTunes I've had two incidents today where the computer will lock up. No screen corruption, but there is no response to the mouse and keyboard. The only thing that can be done is to hold the power button and restart.
Upon restarting there is a message stating that the system was shut down due to an error. The message gives the option to re-open the applications that were open at the time of the crash. The first time this happened all the applications did reopen, except iTunes. The second time they all did. ("They" being Chrome, Mail and iTunes.
Interesting woes. :-)

Perhaps your third-party software is not compatible and require updates (including iTunes.)
Or, you had a dysfunctional system to start, so try:
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. (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 click on the Repair Permissions button. 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.

After upgrading to Mountain Lion on my 2011 27" iMac, my Mac occasionally lock-ups.

After upgrading to Mountain Lion on my 2011 27" iMac, my Mac occassionaly locks up while using Safari, Mail or Dreamweaver and I have to d a force-quit, then restart my Mac. Anybody having similar probelms?
I am thinking about doing a clean install of Mountain Lion. Would I be able to restore my applications and data from Time Machine after the re-install?

My 24 inch iMac... 2.8 GHZ dual core (Early 2008) is having the same problem. After it sleeps, I go to use something... and the beachball of death occurs. This happens multiple times a day... and let me tell you... it is annoying... and I am the one who is being annoyed!
It could possibly be revolving around safari... as that is really the only thing that is running consistently. I don't use iTunes on this iMac as I have so many other Macs up and running in the house... and I never consume media on it... so I kind of dismiss iTunes being the culprit.
This is majorly affecting my Mac... in terms of reliability and uptime... which coincedently is the main reason why I switched to Mac in 2008. This is my only Mac that could upgrade to ML... so I don't know how widespread this is... but I hope that this problem can be solved...
I agree with another person who commented on this issue... do we really need a 10.8.1 update already... to fix this?

Locked out of macbook air after updating to mountain lion? please help

i finally finished downloading and installing mountain lion this afternoon. i went to restart after install and now im locked out. i seem to be locked out by an old find my phone 4digit pin. iv tryed holding cmd and r when booting but it brings up another password which i dont know. please can someone advise me on what to do.
many thanks
Alex

Things like this always happen to me :(
I can remember locking it at work when my mate was playing on it so I locked it as I didn't want him on it and he knows my login pin. However it's been fine ever since this was done 5/6 months ago.
I need it for work in the morning :(
If I call apple with my serial number do you think they can help?

Since I've installed Mountain Lion, I am having lock up issues with multiple programs. MS Outlook has crashed and I've lost all my folders. HELP?

Since I've installed Mountain Lion, I am having lock up issues with multiple programs. MS Outlook has crashed and I've lost all my folders. HELP?

okay I've finally been able to get tor and all the other programs to work according to my plan the only thing that's still making problems is that iptables doesn't work as I want it to, when I start chromium without proxy settings privoxy doesn't seem to forward the information to polipo.. do I need to add another rule to iptables.rules in order for the program to know it has to reroute the information again or how can I get this to work? and is there any way to run rtorrent with proxy support?
anyway, problem 2 and 3 are still to be solved.
and does anybody know where i can get a good dansguardian blacklist that was not designed for 6 year old children and for which I don't need to subscribe? I'm still getting these partypoker popups -.-
//e: with iptables it's the same thing as described in the first post. https works, http doesnt. I get the output "Invalid header received from client." on http sites. still no idea why though.. (and the https-version of torcheck.xenubite says i'm tor unprotected while starting the browser with iptables)

Installing Mountain Lion from Snow Leopard, Install failed and HD write-locked

I recently downloaded the mountain lion installer from the App Store and I ran the installer. Stupid person as I am, I did not have any backups for my file and I naively assumed that an apple OS installer would be without flaws. Boy, was I wrong. I need every bytes of my data (or close to every bytes) but the installer failed.
Mid installation, the installer stopped and said that the installation failed and that I need to repair my disk. So I restarted the computer and I ran disk utilities (my start up disk was the OS installer and the installer allows me to run several programs, including terminal, disk utilities, and by the way, when I held option while starting up to see which start up disks I have, I only had the OS installer as the start up disk. Also, the installer allows me to run a program called "Startup Disk" when I click on the apple logo on the top left corner, but it doesn't allow me to startup my computer using Macintosh HD) and noticed that when I highlighted Macintosh HD, my "Repair Disk" button was grayed out. So first things first, I ran the "Verify Disk" button but after a minute or so, Disk Utilities said that verification failed and that Macintosh HD needs to be repaired. But the "repair disk" button is grayed out! So I went to the Mountain Lion installer again and ran it. Of course, it failed again so I restarted the computer.
So I tried to first back up all files in Macintosh HD to an external hard drive using Disk Utilities, and I used features such as "New Image" and "Restore" but they both ended up in "Input/Output error". I tried many methods with Disk Utilities but they resulted in errors.
After some research, I noticed that some people's computers worked after they reset their PRAM. So that's what I did. I held command+option+P+R when computer started up and I reset the PRAM. When the start up disk (which is the OS installer, not the normal operating system) loaded, I was greeted with choose languages option and then I was back in the Mountain Lion installer state. I again ran the installer again, hoping something would be different, but then it was different. But not in a good way. When I was told to choose where I would like to install Mountain Lion, I noticed that Macintosh HD was grayed out. Last time, I was at least able to run the installer but this time, Macintosh HD was grayed out. The installer said that my Macintosh HD was locked. After some research, I learned that apparently, the Mountain Lion installer write-locks Macintosh HD mid installation.
So now I am stuck and I am thinking of two things (plus some questions)
1. I am wondering if there is a way to unlock Macintosh HD. But even if I can unlock Macintosh HD, there is no guarantee that the installer will successfully install Mountain Lion, am I right?
a. so how can I un-write-lock Macintosh HD?
2. More realistically, I am thinking of borrowing someone else's macintosh computer and use it as the backup center. I have a firewire cable and a terrabyte external hard drive. So what I'm thinking is that I'll hook my computer in target mode to my friend's computer and I will also plug in my external hard drive to my friend's computer and then I can download and run Carbon Copy Cloner from my friend's computer to copy all data from my Macintosh HD to my external hard drive. And then I will erase my Macintosh HD, freshly install Mountain Lion onto it and then copy all data back from my external hard drive. But I am not sure about few things.
a. it looks like my Macintosh HD is write-locked. Can I still use Carbon Copy Cloner to copy all data from Macintosh HD (in target mode) to my external hard drive?
b. will my computer allow me to erase (or format) Macintosh HD?
c. will my erased/formatted Macintosh HD able to install + be installed Mountain Lion OS?
If you are here, then you have read my long long problem. Thank you very much and I would really really really appreciate your answers and opinions. Thanks

I'm not sure where you read that about the disk being "write-locked." That doesn't make much sense, given that the major task an installer like this must achieve is writing a whole bunch of files to the hard drive. I think your source was mistaken.
As to what happened, it sounds like your hard drive was badly corrupt to start with, or possibly was on the edge of failing and is now in the process of dying entirely. If you don't have backups of your data, that does not bode well for you, unfortunately. If you can manage to use target mode to copy your data, do that.
Once you're sure you've got all your data, you need to start up from your Snow Leopard install disk and repair the hard drive. (Since it sounds like the Mountain Lion installer didn't work, I wouldn't trust the recovery partition that Mountain Lion installs.) Or, even better, just erase the hard drive entirely and reinstall Snow Leopard. Then, once you're back up and running, with all your data back on the system and with Snow Leopard updated to the most recent version, try installing Mountain Lion again. If any of that fails again, the problem is likely to be a dying hard drive, and you'll need to replace it.

Is there a way of locking a word document in ios mountain lion so that it cant be printed or changed?

Is there a way of locking a word document in mountain lion so it cant be printed or changed?

You can print because it's your document. Others shouldn't be able to. But then it's easy enough to unlock them altogether.
Easiest is to get encryption software and just encrypt the document. Or create a small encrypted disc image with Disk Utility and store the document in the disc image.

Downloaded Mountain Lion from App Store, but it says by disk is locked and won't let me choose the hard drive for installation

I'm struggling to get Mountain Lion installed on my machine, but what is worse is that it has essentially rendered my computer useless (and of course I need to use it urgently). After downloading and installing from the App Store, I have run into some significant problems.
On install, when prompted to "select the disk where you want to install OS X" the hard drive is greyed out and a message comes up that says "The disk is locked."
So when I back out of the install, I am given the option for Disk Utility, Reinstall OS X (same results as before) or Restore from Backup (not backed up).
On the Disk Utility, I can hit Verify Disk and it names an error and says to hit Repair Disk. The error is an "Invalid Sibling Link. The volume Macintost HD was found corrupt and needs to be repaired." Unfortunately, Repair Disk is greyed out and I can't hit it.
What I want to do is just forget the entire process at this point and scrap the upgrade until I have time to figure out what is going on. Is there a way to abort at this point?
Thanks for any help!

Your welcome!
You should always have and keep an up to date backup.
Sounds like you need something a little stronger than Disk Utility. At this point I have no way of knowing if Disk Warrior can or will help.
Depends..!
If you do format and install, then Yes it will.
If you reinstall OS X, then No it will not.
Problem is that according to the Disk Utility message, I don't think that you will be able to install either 10.6 or 10.8.
Those are very good questions. The only bad questions are the ones you have to ask yourself.

The disk is locked when I tried to download Mountain Lion

I have macbook air which is less than one year old. So few days ago, I turned on the computer and there is this flashing folder with a question mark on it. Went to the service centre, and they concluded that everything is okay except that there is a software error and suggest I reinstall the OS through internet recovery. The internet recovery systen require me to have disk to download Mountain Lion. Tries to use my 8 Gb usb drive and it says that it requires to be in gpt format. Finally, made my usb drive to be in gpt format using my windows computer. Then tried to use it again but now it says that my usb drive is locked. Anyone knows to fix this problem? I don't have another Mac so I can't fix it using Mac.

I wasn't able to load to Disk Utility using commad R. I could go back to the main menu of the internet recovery and select Disk Utility to make any changes to the USB drive like making it GPT formatted. Thanks!

I've reset my PPAM before to get around Firmware lock, but I've upgraded to mountain lion and now need to do the same thing, but I can't reset the PRAM. I've heard of the chip that is on the post 2011 macs, but I must not have one? What to do?

I've heard of the chip that is on the post 2011 macs, but I must not have one? What to do? Also, I can not get start up chimes unless I have the factory startup disk in. Can the PRAM be reset with the factory startup disk in or must the mac boot from the hard drive? Need help.

Mountain Lion 10.8.2 (Hosts File Locked)

In OS X Lion 10.7, I had edited my Hosts File to prevent certain web-sites from loading and would like to access them again, however I have noticed that in the latest update of Mountain Lion 10.8.2 the "/private/etc/hosts" file is locked and cannot even be modified in terminal using vi, nano or pica. Does anyone know a way around this? I even tried logging into to the repair volume of OS X to try to no luck. Has anyone been successful?

Okay, after a ton of researching terminal commands, I finally found the solution to my own question.
1) First you need to log-in as the Root User in Terminal using the following command:
sudo su -
2) Then you need to remove the "sticky" lock assigned to the hosts file that prevents people from modifying it:
chflags nouchg /private/etc/hosts
3) Then you can edit the hosts file as per usual via the following command:
sudo nano /private/etc/hosts
"Control O" to Save
"Control X" to Exit
4) Then in Mountain Lion you should flush your cache to ensure the new hosts file is current:
sudo killall -HUP mDNSResponder
5) Go ahead and reapply the "sticky" lock so the hosts file doesn't modify itself:
chflags uchg /private/etc/hosts
I hope this helps!

How to stop files from being locked in Mountain Lion?

In the last week, I have found several of the files that I have generated or downloaded have become locked. Since Apple has eliminated the Auto locking feature that use to be in Time Machine. The files include PDFs, PHGs, TXTs, etc. How do I stop files from being locked? How do I unlock the ones that are locked? I can not emtpy my Trash.

When I went to "Get Info" on one of the locked files [a TXT file] per your steps, I noticed that the there was a Locked box checked. I unchecked that box and was then able to remove the files from Trash without any further action.
Do you know why it got locked in the first place since Mountain Lion does not automatically lock files as the older OS X version did? Do you know how to prevent it from happening again?
I want to thank you for your suggestion.

After updating to OS X Mountain Lion, there is a password locked pdf document in the Downloads Stack. Does anyone know what password is required to access this file?

Hello, if your install disk is locked (I assume with FileVault) there is no way to change the password. If it weren't locked there were at least two solutions. As far as I know, the only solutions now are:
- contact your dad
- erase and reinstall the OS X clean
Let us know.

What happened to auto-lock in mountain lion? I need it back.

I had my whole company upgrade to Lion, so we could use the well thought out source control features of the desktop. One of the key features was auto-lock. This prevents someone from accenditally changing a document without commiting to it. The auto-locking made the other changes such as duplicate make sense.
Now these are gone in Mountain lion. Which also makes the other changes to the file system like duplicate superfluous.
How do we get them back? Do we have to be stuck in Lion forever? Who puts in new features in an OS, just to remove them wihtout an option in the next cycle? That is inane.
Is there any way to turn this back on?

Go through each of the sources Music, Movies etc. and select Playlists. Use the elipsis ... to enable sources. Apps, Tones, and Internet Radio don't have a Playlists button, the others do and remember your selection. Not exactly the same as the old sidebar, but not too different.
