Is it possible to downgrade to mountain lion with the help of a time machine backup after having updated to Mavericks?

Just to be clear, if by downgrade you mean uninstall, then the answer is technically, no.
You can't uninstall an OS. You can erase and re-install the old OS, but if you don't have a prior backup of your data, you'll lose it during the erase procedure.

Where do I find the Library in a Time Machine backup after Lion installation?

Where do I find the Library in a Time Machine backp after Lion installation?

You can access the backups of another computer by holding down the option key and selecting "Browse other Time Machine disks" from the Time Machine menu in the menu bar. As for getting to the Library folder, you would have to use something like the free application "Tinker Tool" (not "Tinker Tool System") to make hidden files visible in the Finder, then enter Time Machine.

Is it possible to downgrade to Mountain Lion on the 2013 Mac Pros?

Obviously came with Mavericks, but would like to know if it's possible to run 10.8.
Thanks!

While that is typically the case, I've noticed the new MacBook Air and Mac Mini will allow you to install Mountain Lion
That is because both models were released before Mavericks was available. Mountain Lion is their original OS.
The 2013 Mac Pro can not run anything lower than the custom build version of 10.9 it shipped with.

Mountain lion mac osx 10.8.3 time machine backups are not visible in time travel window. Why?

Time Machine shows that it's backing up every day. It recognizes my selected backup drive. The backups appear in that external drive.
However today I opened the Time Travel Window and it says, No Backups Available.
Whazzup?

Unmount and remount the drive. Same thing?

Time Machine Backups after recent upgrade to Mountain Lion

Basically to keep a long story short - i need to take my computer in for repair tomorrow. I recently did an upgrade to Mountain Lion a day or two ago. I haven't done a Time Machine backup until today (a couple days after i upgraded to Mountain Lion) because i wanted to make sure that my previous TM backup (Snow Leopard 10.6.8) was the most up to date and best update that i could revert back to if i had any issues with Mountain Lion, or any application compatibility, etc etc.
I don't have any broken applications and it seems like Mountain Lion is running better than Snow Leopard. However, as i said - i'm taking my computer in for repair tomorrow, i would like to know that i have the most up to date Time Machine backup with the new Mountain Lion so that when i restore it back from my Time Machine backup after i get it back from repair, i won't have any issues with the migration, which could potentially lead me into more technicalities.
I have a 500GB Harddrive, with about 70GB left of free space....I did the initial backup prior to upgrading to Mountain Lion, and it upgraded 400+GB of info, now, since Mountain Lion - the first backup with Mountain Lion initially said 46GB - then it went down to 14GB by the time it was all said and done....so what exactly did it back up?
Did it back up all the necessary files to keep Mountain Lion running smoothly when i restore it back to the way it was after i get it back? Did it not back everything up that it needs to? Is it safe to erase my internal drive and do a clean installation so i can take it in, and not worry about not being able to migrate things back over or applications not working correctly?
When i get it back, i presume it will come with Mountain Lion back on it and i can just boot up into the Recovery Disk and restore it from a Time Machine backup that way, correct?
Thanks for the help.

I received the same error and experienced the same issue that you have described but after performing a Time Capsule soft reset and then toggling the TM Off and then back On I was able issue a backup now and see my previous backups.
Here is the link to where I posted my fix; https://discussions.apple.com/message/19069543#19069543. Someone else had success using a different method. The only comment / complaint that I have since the ML OS X upgrade is that TM now takes at least 20 to 30 seconds before I can click/select a backup.
I hope this helps.

Imac keeps crashing in time machine backup after upgrade to mountain lion

2008 imac kept crashing (shutdown and restart) during first backup after upgraded to mountain lion. The backup size was about 10GB but time machine crashed after a while (at most 2GB) and never completed backup. So, I don't have any backup since right before I upgraded from Lion. Any suggestion?

Something strange happened. I was able to get time machine to work by going out to the login screen (the account kept logged in) and let it run the backup with the screen off (screen auto off after a few min). I tried it on two different external drives and that did the trick on both. Since the initial Mountain Lion backup was huge (155 GB), I was quite surprise that it worked at all. I assume your MBP was a Lion to ML. I also just did a 2012 MBP upgrade but that one was smoother. I did not recall having crashing issue. One thing I did find during this was that my WD passport USB drive was corrupted. Not sure it was the cause or not. I had to erase and reformat to get it back to work. Maybe do a verify disk to confirm. Good luck.

Can't restore Time Machine backup after iMAC (Lion) Refresh

I recently did a refresh of my iMAC with OSX Lion. I have been using time capsule to back up my iMAC as well as my Mac Mini for the last 6 months with what I perceived to be no issues.
When I got to the part in the MAC start up to restore from backup it couldn't seem to find the iMAC backup, only the Mac Mini backup so I skipped that part. I then tried to use Migration Assistant later and the same thing, I couldn't find it. I used finder to locate the Time Capsule and was able to find the backup, but when I double clicked on it said "Mac OS X can't repair the disk "Time Machine Backups". you can still open or copy files on the disk, but you can't save changes to the files on the disk. Back up the disk and reformat it as soon as you can".
Even though it said that it open a new finder window and I was able to find the backups and I proceed to copy of the files over. All seemed well until I opened iPhoto and it wouldn't open (just hung). I did a library restore/repair by clicking Option + Command when opening and after it ran iPhoto opened. When I browsed around though some recent pics that I uploaded either weren't there or corrupted and all my faces were gone.
I did a fresh install again and tried all over and the same thing happened. Any help on getting back my old backup? Seems to be corrupted or something, but I'm not sure.
See previous post before this... I was told to post my problem here - as I originally posted on the iPhoto forum before I realized I had a time machine / capsule problem.

Help would be appreciated.

Hi there,
I had a look through and I tried to do option A5 - which is repair or verify disk. I dragged the sparebundle for the mackup to disk utility and after trying to do a repair I got the message "disk utility stopped repairing "Time Machine backups".
Does this mean that my backup is corrupted and useless for a restore with time machine?
Yes.
And that also means copying via the Finder may not get everything. Corrupted is corrupted.
Assuming you copied from the most recent backup, you might want to try copying just the iPhoto Library from an earlier one -- that might not be damaged. If you have room, put it somewhere else, like your desktop. Or if you have an external HD, that would work.

Can't install Lion This disk is used for Time Machine backups

The Lion installer, downloaded from the app store, won't let me select my internal hard disk, it says "This disk is used for Time Machine backups" which it isn't.
Any ideas?
Thanks
Neil

I was sure that I had trashed the Backups.backupdb folder from the top level - it did require me to enter my Admin password.
Yes I had tried several times to go back to the terms of agreement screen and click agree once again, but still had the problem.
I had external HDs connected, but disconnected them and the problem persisted.
I restarted my mac and now the message has gone away and I am having no problems installing.
Thanks everyone

Error-1 time machine backups after lion upgrade

I upgraded to Lion on both my computers. My iMac Time Machine Backups are fine - it's connected by firewire to an external hard drive.
BUT my Macbook Tim Machine Backups are wireless using our Time Capsule and the backups are stored on the Time Capsule.
Since upgrading, The backups fail & I get this error: The backup disk image “/Volumes/Brunnertime/LittleOne (2).sparsebundle” could not be accessed (error -1).
Just like so many other unhappy Lion users.
One positive abberation - Last night, I went into Time Machine Preferences, re-selected the appropriate backup disk (our Time Capsule), entered the password, started a backup and VOILA it backed up fine. All night long, it did hourly backups.
This morning? Once again, the backups are FAILING with that same error - The backup disk image “/Volumes/Brunnertime/LittleOne (2).sparsebundle” could not be accessed (error -1).
Plus, now there are NO backups on the disk. Huh?
At this point we are disgusted that both Lion and iCloud (that's another longer story) were released before they should have been. Too many bugs.

Hey, finally I found a permanent fix for this issue. I read about it at another Apple Discussions Forum, but right now I don't remember where.
It worked for me at least. In my case it seems that some Western Digital (WD) software was causing the issue. I just uninstalled WDSmartWare from my iMac using that application's own uninstaller, rebooted my Mac and, finally, after months of calling Apple Support with no luck, it all started to work normally again, so check if you have some WD software running on your Mac. In my case I didn't even need that WD software, as I had it because I used to back up to a WD Drive which I don't use anymore since I bought my Time Capsule.
Feel free to reply if you require any further assistance.
Good Luck.

I upgraded to Mountain Lion and now I'm having trouble with Time Machine. It appears that since the upgrade Time Machine is not recognizing the external hard drive. When I go to Time Machine and select Disk for the current HD I am left with one of two options: "cancel" or "remove Disk." I am worried that I will loss my backups.

Is this a usb drive?
It will probably never recognise that drive ever again.. Mountain Lion has this little bug where it cannot recognise some USB drives.. I don't understand it.. but it just happened to me and a quick google shows it is not uncommon.
Your backups are not lost.. they are just not accessible.. you need to plug the drive into a computer with a better.. older OS. Find a new USB drive that Mountain Lion can actually read.. and even write to.. and copy the files across.

Why would upgrading from Lion to Mountain Lion more than double the size of my Time Machine backup?

I have a 500GB Time Capsule that has 248 GB used. After upgrading from Lion to Mountain Lion, Time Machine reported that there was no longer enough room on the TC to complete the backup. Surely the new system files aren't taking up over 200GB? Does it somehow want to copy all of my user files again, even though the vast majority of those haven't changed since the previous backup?
I'd like not to have to upgrade to a larger TC just because of a system upgrade.
Thanks in advance.

If it is working as expected, what do you need with the old backup?
If you want to be able to go back to where you were prior to an upgrade, isolate that backup and don't use it again. As far as Time Machine can tell, the whole drive changed.
The link I posted contains probably everything that anybody knows about Time Machine and how to manipulate it to work as you would like as opposed to how it was designed to work. There are FAQs to continue a backup as opposed to starting fresh, but I wouldn't recommend it for the reasons above. Pondini probably doesn't, either.
If you are going to do a wholesale upgrade of the OS, I would create a bootable clone using something like Carbon Copy Cloner or Super Duper. A bootable clone on an external drive can have you back up and running instantly if the upgrade fails in any way. If the upgrade goes fine, store it away in case you find the current system isn't to your liking.

Cannot Access Earlier Time Machine Backups After Upgrade To Mountain lion

I went into Time Machine to recover some past emails. It shows that it had backed up my emails for the last year, however it will not let me recover anything before my upgrade to mountain lion. Does anyone know of a workaround for this problem. Thank you.

Once it does finally recognize (after a good while) it simply says "Error, time machine could not complete the backup"
There should be more to that message. See #C2 in Time Machine - Troubleshooting. It will show you how to locate the message(s) that describe the problem, then help you fix it. If that doesn't help, post back with details, including all the messages, your setup, what you've done, and the results.

Is it possible to play videos or clips with the appletv from an Time Capsule direct without other hardware?

I want to play videos, movies and music-clips (either mp4, other formats or out of an itunes-db) on my appletv without using other hardware than the apple tv an the Time Capsule (except the tv ;-) ). Is it possible to stream direct from the Time Capsule? With other and even cheaper NAS-Storages is it possible, eg. with the ps3 ...Thanks for help.

The TC from the day it was introduced until today.. has got a bigger hard disk and gained dual band wireless.. but nothing substantial.. it is not a NAS and has never been more than a target for TM mostly laptops as any desktop Mac can have an external drive for backups cheaper and faster than TC.
Many people were disappointed that Gen4 was a nothing upgrade. it is just a Gen3 with a different wireless card. Don't know if there will even be a Gen5 as Apple seems to see Cloud as the answer for remote storage. I would not be surprised if it was dropped completely. But who knows.. Apple sure don't let any secrets out of the bag.
And for the AppleTV 3 there is no JB or other things possible at this moment?
Not yet.. we are awaiting as some major effort is being expended. There is a hack just recently for the ATVv2 with v5 of iOS.. so the v3 may not be far behind.. v2 are commanding high prices at the moment on ebay though.. near to double purchase price when they sold out before v3 arrived.. as people discover their TV watching plans are now in tatters. Or their library of movies is no longer accessible.

I've been locked out my MacBook Pro, I was able to lock the MacBook with the find my iPhone app but I'm unable to unlock it with the app or by punching in the code directly to the MacBook, so far the apple store or reps over the phone can not help. I've called a third party retail store for assistance and the tell me I have to pay, even if I get it to work or not... So far nothing these apple "genius" will do to help with this product solution.
I know my passcode/password but I am not able to log in....
Is there anyone that can help?

I would guess the fan is the cause of the noise. Suggest you take a look at it.
This site has a wealth of information about getting inside a Macbook or Macbook Pro.

Downgrade to 10.6.6, then how to use Time Machine backup?

Due to multiple problems I'm having with PDF files, Word 2011, and printing, I've now decided to downgrade back to 10.6.6. I don't know the best way to do this.
1) If I use a TimeMachine backup, I know I can restore the system back to when I was still running 10.6.6, but how do I retain all the email, documents, apps, etc that I've saved or installed since that time? And is there an easy way to tell which backup was the last backup done while still running 10.6.6? In other words, how can I use TimeMachine to roll back to 10.6.6 without losing anything else?
2) If I use my SN install disk to reinstall the OS and then run the 10.6.6 Combo update, will all the user files be retained? If eveything would work properly, would I lose anything other than 10.6.7?

Instead of downgrading, maybe updating would fix your problems? A Snow Leopard Font Update was released earlier this week: http://support.apple.com/kb/HT4605
