Time machine question when installing Mountain Lion

I have a 2010 iMac running OS X 10.6.8 Snow Leopard.
I am preparing to install Mountain Lion, and can't find any instruction about what to do
with my Time Machine which is on an external hard drive.
Do I eject it before I install Mountain Lion and then just plug it back in afterwards?
Will I still be able to see the older backups?
Thanks

No, and yes.

I am getting error "The disk is used for Time Machine Backup" when installing the new OSX Mountain Lion upgrade"

I am keep getting this error "The disk is used for Time Machine Backup" when installing the new OSX Mountain Lion" when doing the upgrade to newly OS.

The folder would be at the root of your hard drive. Double-click Macintosh HD and look there.
If it isn’t there, I’m not sure what it is seeing.

Can I use time machine to revert to Mountain Lion from Maverick?

In spite of everyone saying how great Maverick is, I have poblems with slow operation, hard to use mail addresses, problems with iPhoto, etc. So I want to go back to Mountain Lion. Can I use Time Machine to restore back before Maverick was installed?

Only if you have a full backup of Mountain Lion on your Time Machine backup drive. Then you can boot to the Recovery HD that is on the Time Machine backup drive, erase your drive, then do a full Mountain Lion restore. But if you have already used Time Machine to backup your Mountain Lion system, then this won't work. You will need to erase the drive and reinstall Mountain Lion separately. Then you can restore your Home folder from the Time Machine backup.
Or you can avoid all the above by trying to fix the problems with your Mavericks system. You will need to upgrade iPhoto.
Try these in order testing your system after each to see if it's back to normal:
1. a. Resetting your Mac's PRAM and NVRAM
    b. Intel-based Macs: Resetting the System Management Controller (SMC)
2. Restart the computer in Safe Mode, then restart again, normally. If this doesn't help, then:
     Boot to the Recovery HD: Restart the computer and after the chime press and hold down the
     COMMAND and R keys until the Utilities 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.
3. Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the Utilities 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. Select Restart from the Apple menu.
     Reinstall the 10.9.3 update: OS X Mavericks 10.9.3 Update (Combo).
4. Reinstall Lion/Mountain Lion, Mavericks: Reboot from the Recovery HD. Select Reinstall Lion/Mountain Lion, Mavericks from the Utilities menu, 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.
Reinstall the 10.9.3 update: OS X Mavericks 10.9.3 Update (Combo).

How do I make a back up on Time Machine before upgrading to Mountain Lion?

A detailed process would be greatly appreciated. I've heard I should use time machine before upgrading to Mountain Lion for reasons I cannot remember.
Thanks!

Connect an external drive to your Mac. Open Disk Utility, it is in the Utilities folder in the Applications folder, and see if the external is formated Mac Extended (Journaled) and if it is not you can either use the Partition tab to Re-partition it as one partition and format it Mac Extended (Journaled) or you can use the Erase tab to Erase the drive and format it the Mac format. Name it anything you like.
Once that is done close Disk Utility and open System Preferences and go to the Time Machine Applet. Once that is open, If OS X doesn't ask you if you want to use that external as a TM backup disk, select "SelectBackup Disk" and select that external as a place to store backups. Then move the slider from Off to On and then TM will start the process of making a backup of your system. Once it is finished I suggest you turn it back off.

Error when installing Mountain Lion. I'm stuck...

I'm trying to install Mountain Lion to my iMac. After getting the instalation under way I returned to see an error. I tried to reinstall in and had no joy. I read a few things on the discussions and so have tried to repair my disk in DU - after verryify disk the repair option is greyed out. I've tried to erase my disk and start over, but I can't get it to 'unmount'. I've tried to restore from my time machine but get an error message about volume's being used. I've read the info in the little operations manual about repairing, restoring and reinstalling and tried that. Nothing.
I'm stuck.
Any ideas?
Thanks very much.

This says Snow Leopard, but it applies to Lion as well.

Can't back up Time Machine since upgrade to Mountain Lion

When auto back up would be starting, I get an error message "Can't access the backup disk...TIme Capsul" (OSSStatus error 89.)
None of the usual "go to settings" etc. are leading me anywhere useful.
Do I need a patch to make Time Machine/Time Capsule compatible with Mountain Lion?
Di I need to use iCloud as my back up method? (Have not been using iCloud for anything so far).

Time Machine and the Time Capsule is compatible with Mountain Lion. Look in Time Machine Troubleshooting for a solution.

Time machine back up in mountain lion

I have just installed mountain lion on my iMac. I am using a Seagate 1Tb hard disk for Time backup. After some time the computer just disconnects the hard disk and I have to remove the cable and reinsert to get back the hardisk and restart the time machine. This is the problem with my iMac as well as my macbook. What is the solution so that I may have continous, uninterupped back up?

Below is a full log from my latest time machine back up. Migration assistant still cannot see it. Any thought would be grateful

When installing mountain lion on my computer, why does it say "OSX Mountain Lion couldn't be installed, because the disk \ is damaged and can't be repaired."

I'm unable install mountain lion on my computer. Every time it says "OSX Mountain Lion couldn't be installed, because the disk \ is damaged and can't be repaired. Click restart to restart your computer and try installing again." So I press the only button listed as an option, it restarts, and the same screen comes up again. I can't make mountain lion go away...I've tried many times. What is wrong with my computer? It's stuck like this and I can't even get snow leopard back on there if I wanted to because I can't get away from the same screen. Please help : (

Insert your OS installer disk in the optical drive. Power the Mac down by holding down the power button. Then power back up and hold down the 'c' key so the MBP boots to the installer disk. From Disk Utility you should do a Repair Disk. If DU successfully repairs the disk quit the installer and reboot your Mac. You should update to 10.6.8 prior to upgrading to ML.

Then do your ML upgrade install.

Time Frame for re-installing Mountain Lion?

I decided to completely re-install Mountain Lion using the reboot and holding down the command and R keys at the same time. The Download of the OS took about 1.5hrs-2hrs but the actually installation is still going.
It's literally getting to about 9 hours since the actual install has begun. It is EXTREMELY slow. Each time frame that it gives me is inacurate. by the time it goes from "15 minutes remaining" to "14 minutes remainig" it's already been 30min-1hr. It's been at "about a minute" for almost an hour now.
Am I doing something wrong or is this normal???
I'm using a Macbook Pro that I just bought from the Apple store about 4 months ago. 500GB HDD and 4GB RAM.
This is so frustrating. I've never had this type of issue with a PC before. 9+ hours to install an OS? That's laghable. $1500 paperweight sitting just infront of me.
And the reason I decided to completely reinstall the OS is because my computer was slowing down and freezing. Found out it might be the indexing it was doing out of no where for spotlight but even after turning off indexing it still was running slow. Apple wanted to charge me $20 to fix the bugged "functionality".
And also I have checked the HDD to make sure nothing is wrong with it.

Wow, glad so many folks have read it but no one has replied except myself, I posted it. Guess no one knows out there and Apple reps aren't responding.
Lots of folks complaining about slow issues but no fixes from Apple.
Not good.

Encrypted Time Machine Backup Lost in Mountain Lion Install?

Hi,
Operating 10.7.4, I make use of 'time machine' encrypted backups to an external HD. If I wipe the HD and do a fresh install of 10.8, will I lose the encrypted backup? Of course I know my passwrd and I don't rely on the keyring, but if there is some certificate exchange between OS and TM, there is a possibility that installing a fresh OS, I will lose access to the disk? Is there any official documentation that addresses this concern?
Thanks, cheers.

No. It's password only. You can even access it on a different Mac (Lion or ML) with the password.

Restoring files from time machine backup made using Mountain Lion

Hi Guys
I have trawled through the Internet and found many sources of help for some of my headaches but still can't help the problem. So here I am.....
I have an early MacBook Pro 13" that came with snow leopard. I immediately updated to lion which was a disaster being so slow etc. Then I upgraded to mountain lion which was pretty good. I always upgraded and never clean installed.
I have been running time machine on a Qnap nas (model 212) which I must add has been a headache to get going in itself.
Anyways I recently upgraded to mavericks which made my MacBook grind to a halt. I mean even the beachball was struggling. To the point after 2 weeks I couldn't get anything done on it!
So I decided to do a clean install. Did that and then tried to do restore files using migration assistant at first log in. Turns out my back is corrupted!
Now I know I have a good complete backup of my mountain lion system just 2 weeks old on my nas. Only problem is that mavericks won't let me get to that when I try to upgrade from that drive as it just says no OSX backup available.
Now I am trying to install snow leopard cleanly and the try and upgrade to mountain lion hoping that it would recognise the mountain lion backup on my nas.
Can you please let me know if I am going in the right direction?
Any help appreciated guys.
Thanks

Everything since the fresh install, has to be done manually from my Backup drive. Wasn't, or isn't TM supposed to do that automatically (for example restoring iTunes, is it supposed to restore just the application or all the folders with it as well?). Why, when I select a folder with many subfolders in it (and eventually the files I want within) does it say that the original whatever doesn't exist anymore at that location, then I have the option to choose a new location or to recreate the enclosing folders? I Click on recreate but when I do, just the top level shows (the first folder, for example, garageband). No more folders are shown inside, despite there being plenty of files in my backup version. Am I misunderstanding TM's powers/capabilities here? Is it supposed to be this frustrating and difficult?
Everything that I want has to be done manually it seems. I don't understand it. The other thing is that it denies me access (I don't have the privileges or whatever it says) to move the files directly via the mounted disk on the desktop rather than entering TM. So, I can't go into TM and click restore, I can't manually open the mounted drive and drag files (denies me permission). The only way I've been able to do anything successfully is to archive the **** folder/s or files.
Any help or direction, or a manual on how to use or tutorial on Time machine would be great. Someone point me in the right direction please, this is highly annoying and I am debating switching back to Leopard (having issues with iChat in Snow Leopard).
Thanks

How do I fix Time Machine from crashing in mountain lion

Hi,
I recently had to wipe my SSD on my rMBP as I couldn't partition the drive in order to install Bootcamp. I managed to eventually erase the drive and setup a new partition for Windows. I then reinstalled Mountain Lion via the internet and hooked the computer up to my Time Capsual to do the restore. Restore did not restore to my latest backup and when I go to time machine to do a restore I am getting 2 things happen:
1) Dates of retre points are all listed in Purple.
2) Unable to select any of these dates as the software appears to freeze.
Anyone know why this is happening?
Thanks

Another option to check your backups is through the Finder window.
Connect the external HD to Mac - or connect to the IP address where the HD is connected to (GO-Connect to Server).
-In the HD you will find the backups.backups folder - folder of your Mac - folders of each back up.

"Repair disk" when installing Mountain Lion

I was just upgrading to Moutain Lion OS X right now when it tells me my disk needs repair. I tried, but it says "Macintosh HD couldn't be verified properly" (might not be exact wording, it's in Norwegian for me). When I click the "repair disk" button nothing happens, it just gives me the same message.
What are my options? I do have a back up (time machine), BUT it's from 2 years ago and thus I'd be losing a lot of files I have on here since after then, and that would really suck..

Then quit the Mountain Lion installer. Do you have a bootable system on your external hard drive? If so, then boot from it as follows:
Boot Using OPTION key:
Restart the computer.
Immediately after the chime press and hold down the "OPTION" key.
Release the key when the boot manager appears.
Select the desired disk icon of the external HDD.
Click on the arrow button below the icon.
Once you have booted from the external drive do the following:
Repair the Hard Drive and Permissions
Open Disk Utility from the Utilities folder. After DU loads select your internal 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.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
Restart the computer. Locate the Mountain Lion installer in the Applications folder. Now see the following before proceeding if you want to make a bootable USB flash drive installer:
Make Your Own Mountain/Lion Installer
1. After downloading Mountain/Lion you must first save the Install Mac OS X Mountain/Lion application. After Mountain/Lion downloads DO NOT click on the Install button. Go to your Applications folder and make a copy of the Mountain/Lion installer. Move the copy into your Downloads folder. Now you can click on the Install button. You must do this because the installer deletes itself automatically when it finishes installing.
2. Get a USB flash drive that is at least 8 GBs. Prep this flash drive as follows:
Open Disk Utility in your Utilities folder.
After DU loads select your flash drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
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.
Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
Click on the Erase button. The format process can take up to an hour depending upon the flash drive size.
3. Locate the saved Mountain/Lion installer in your Downloads folder. CTRL- or RIGHT-click on the installer and select Show Package Contents from the contextual menu. Double-click on the Contents folder to open it. Double-click on the SharedSupport folder. In this folder you will see a disc image named InstallESD.dmg.
4. Plug in your freshly prepared USB flash drive. You are going to clone the content of the InstallESD.dmg disc image to the flash drive as follows:
Double-click on the InstallESD.dmg file to mount it on your Desktop.
Open Disk Utility.
Select the USB flash drive from the left side list.
Click on the Restore tab in the DU main window.
Select the USB flash drive volume from the left side list and drag it to the Destination entry field.
Drag the mounted disc icon from the Desktop into the Source entry field.
Double-check you got it right, then click on the Restore button.
When the clone is completed you have a fully bootable installer that you can use without having to re-download Mountain/Lion.
Note: The term Mountain/Lion used above means Lion or Mountain Lion.
As an alternative to the above you can try using Lion DiskMaker 2.0 that automates the process.

New macbook pro with mavericks but time machine back up with Mountain Lion

Due to an incident with a cup of coffee my 2009 Macbook pro was unexpectedly destroyed. However I now have (thanks to Insurance) a new Macbook Pro which runs Maverick. I have a back up of my Mac from Time machine however my latest back up was using Mountain Lion, am I going to be able to re-install this back up onto my new computer? If not how can I get my data out of Time Machine onto my new mac?

You need to erase and format the new HD as OS X Extended (journaled), restore the TM backup onto it, and then reinstall Lion to put on the Recovery HD. Best is to do all of that in an ext HD enclosure, ensure that it boots the MBP, and then put it into the MBP. Once that's done and, if the MBP supports it, upgrade to Mtn Lion, which is what Lion should have been when it shipped.

What do I need to watch out for when installing Mountain Lion from scratch?

I feel like it's a good moment to erase everything from my computer and reinstall Mountain Lion. I'd like to know which things I should watch out for.
Most of my important stuff is located on an external hard drive. Some of the applications are located there as well, the other ones I can simply re-downloading, I don't mind this.
I have my whole iTunes library and my iPhoto library which obviously I'd like to keep. I'm also concerned about my text messages on my iPhone -- they're very important to me. And so are also my Notes, Reminders, and Contacts.
The thing is, I do not want to do a fresh install and then reload a backup. What would be the sense of making this? None I guess... I'm doing a fresh install becuase I believe there's lots of useless files and maybe even dangerous files on my Mac that I'd like to get rid of. I guess that if I would load the backup, they would all be here again...
Is it maybe possible to load only certain things from Time Machine, for example my iPhoto or iTunes library?
Maybe someone can help me here, totally new with this...

Alright, I'm slowly getting ready to do this. Apparently I do not need an install DVD but I can just press CMD+R to get to the option to do a fresh install, that's why my Mac didn't come with an install DVD (that's what I've read and what I've been told at least).
Now I'm wondering... do I need to copy those items from the User folder at all? I mean, I have a complete backup on an external hard drive. I could just go there in the folders and select what I would like to copy to my Mac again, suchs as my music library or photo library. Is there any risks? I'm worried about even the smallest things, like creation dates changing and stuff like this. They mean something to me
