If i upgrade my current OS X version to the latest version, can i go back to previous version via the time machine backup?

If i upgrade to yosemite which the majority of ratings are poor (thats probably my answer) can i revert back to lion via the time machine back up I have on an external hard disc?
***So if I upgrade my OS X and dont like it, can i jump in my time machine and go back in time to my previous OS X?***

Yes, you can restore back to a previous OS that you backed up on Time Machine prior to upgrading.
If you're not sure you will like Yosemite, why not create a 2nd partition on your internal drive or to an external drive and install Yosemite there. This way you keep your current system in tact and get to try out Yosemite.

Time Machine only shows the current copy of the file I am trying to restore. There is none of the time machine backup histories shown. I am running OSX 10.7.5. I see the backup files on my external Time Machine hard drive. Help

Upgraded to FF5 a week ago, nothing but problems since; can I roll back to previous version!

I notice on the Help files that I am not alone in having problems with FF5. I have tried running in Safe Mode and am now stuck in this mode! Nothing including re-booting will shift it. PLEASE - how do I get back to previous version - 4.nn

'''For those that really need an earlier version of Firefox''', find your system and the Firefox version you want in releases, download and start the install.

Time machine backup of mavericks gone after yosemite upgrade

I am a podcaster and enjoyed the podcast format in garage band. However, after upgrading to yosemite, my garageband is gone. So (annoyingly) I had to buy it again.
However, after doing so, I learned that in the latest version (10.0.3), podcast formats are not supported. I know I have the old garageband (10.0.2, I suppose) on my time machine back up of mavericks.
I figured I would just pull that single application out of the backup and throw it into yosemite. Not happening, because whenever I pull up time machine, it has marked the date that I made the backup, but it wont let me access it. It doesnt even tell me I can't. It's as if its not there, but then when I open my External HD in finder, there it is, the time machine backup file.
I read somewhere that when you first plug in the HD after upgrading, it has to "index" the HD, but after leaving it plugged in awhile, there appears to be no change. I've messaged apple about this over a week ago, and no reply whatsoever. Their customer service has really hit the fan these past few years.
Anyway, any advice would be appreciated. I'd like to get back to my podcasting. I should have never upgraded, but now I cant go back to mavericks because I can't access the **** back up.
Regards,
Colin

Yes, backups should be accessible.
I've been running Time Machine since it was launched (Leopard, I think) and have upgraded through all iterations of OS X and am currently on Yosemite. Whenever I've needed to restore a file (not often, but it does happen) that was created whilst running an earlier OS X they have restored as expected when running Time Machine from the latest OS.

Can't reconnect to Time Machine backups after upgrade to Yosemite

I did a clean install of Yosemite and restored the user accounts from my time machine backup. I reconnected to the time machine backup on my time capsule and performed a backup. That went fine.
Now I can't access any of the backups made before I upgraded to Yosemite. They all show up in the history bar on the right in time machine but when I click on a backup nothing loads. I've run a verify on the backup and it passes. Looking at the backup file it has 400GB of data, the same as before the upgrade to Yosemite.
Any ideas why I can't access the backups?
Thanks,
Marvin

While in Time Machine, press the key combination shift-command-C. The front window will show all mounted volumes. All snapshots should now be accessible. Select the one you want and navigate to the files you want to restore.
If you need to restore from a backup of the hidden user Library folder, first select a snapshot, then press shift-command-G. A Go to Folder dialog will open. In it, you'll enter the path to the folder. The dialog will help you by automatically completing the parts of the path when you start to type them.
The path begins with slash character ("/"). Enter that. The rest of the parts will be separated by slashes.
The next part is the date and time of the current snapshot. Enter a "2", and the rest of the date should be filled in automatically. Press the right-arrow key to jump to the end of the path. Enter a slash to start the next part.
Next is the name of the volume (usually "Macintosh HD" unless you gave it a different name.) Start to type that, then jump to the end and enter a slash.
The next part is "Users", followed by a slash.
Next is your (short) user name, which is also the name of your home folder.
Finally, enter "Library", then press return. You should now be in the Library folder. From there you can get around as in the Finder.

Upgrade leopard to snow leopard with preexisiting snow leopard time machine backup

I was using an old desktop Mac that had been upgraded to snow leopard from leopard a few years ago. Disk utility said I needed to repair my hard drive using the installation discs. I didn't have the snow leopard installation disc but still had the leopard installation disc which I used. When the computer re-installed leopard onto my hard drive, it created a partition: one with my hard drive running snow leopard, and then a new one with the space left over, running leopard. I got my replacement snow leopard installation discs and would like to delete the leopard partition, and go back to what I had before with the snow leopard drive. I do have a time machine backup (somewhat incomplete) and am making a copy of the physical snow leopard drive. I cannot access the most recent time machine backup since I'm back to running leopard and the time machine backup was made under snow leopard. I'm not sure how to proceed from here to upgrade to snow leopard. When I try to upgrade to snow leopard, I'm asked which destination drive to use. I don't want to use the snow leopard drive, since it would get deleted. So, would the leopard drive be the answer in this case? And what would happen to the contents of my old snow leopard drive? Would I end up with two partitions, both with snow leopard, but one being current (nothing on it) and the other being my old drive? Would I be able to get rid of the current drive and then use only my old drive? Thanks in advance for any help.

First of all, it's unclear to me why you cannot select the old Snow Leopard partition.
I also think you should have been able to repair hard disk using the leopard CD disk without actually installing leopard OSX by using the Utilities only.
Also, Why is your Time Machine backup incomplete? Is that under Leopard or Snow Leopard?
Now you have two partitions with two different OSX (Leopard and Snow Leopard). Your goal is to get back to Snow Leopard.
I going to assume that the original Snow Leopard partition is inoperable (this is also question?) I would upgrade the Leopard partition to Snow Leopard. Afetrwards, use the Migration Assistant to bring in your data, documents, app, and settings. Once complete, you should be able to see your Time Machine backups. If all is ok then you can delete the original Snow Leopard partition.
This is a somewhat complicated situation, so I am issuing a caveat that is my opinion only. Wait until another expert provides input regarding your situation to determine the best course of action.

Time machine backup between OSX versions?

Hi,
I have a 2006 Mac Pro with OSX10.7 installed, I decided to upgrade as the newest versions of OSX aren't supported. My question is could I restore my OSX 10.7 time machine backup to OSX 10.8? Or would it change the OSX version to 10.7 on the new machine? If so is there anyway to restore the time machine backup without losing OSX 10.8 or having to buy and reinstall it?
Thanks, Tom

Once you have bought a version of Mac OS X, you may re-download and re-Install it as often as you like without paying again -- provided you use the same Apple-ID to do so.
A 2006 Mac Pro cannot run 10.8, so I do not understand the rest of your query. That Mac is stuck at 10.7 as the highest it can run. If you attempt to download 10.8 to it, it should refuse to do so, offering instead the highest purchased version that can actually run on that machine.

Restoring Time Machine backup to older version of OS X

Hello all,
I'm fairly sure I know the answer to this, but I'm not finding anything definitive so I thought I'd turn to the experts here. I accidentally posted this to the Mac Pro forum and I'm not sure how to delete it there. Figured I'd post it to the correct place anyway.
I support a school district using MacBook Pro laptops. We are licensed for OS X 10.6 on these machines. A teacher upgraded on his own to 10.8, so I have to wipe his drive and start over with 10.6. He's doing a Time Machine backup to restore his files once he's back on the correct version of the OS, but I'm thinking that because the Time Machine backup was done on 10.8, it won't restore files to an older version of the OS. Is this correct? Thanks for the help.

A, why or where is the master system restore image?
B, Wipe and install
C. Clone the system once installed for future restore
D, support for 10.6.8 for some security updates continue but for how long
E. 10.6.8 can be run in a Parallels or other VM under Lion or later (if it has the processing and RAM to handle a guest VM)
F. TimeMachine - moving between versions and backward does have some challenges, and once it was updated for ML I assume no go
G. Don't have just one backup drive - they could have pulled the old (and probably is old by now) and start fresh with a new backup set and drive.
http://www.apple.com/support/timemachine - best bet would be the FAQs there and the actual subforum for Mac OS. This forum? is for workstations rather than notebook line.

How do i determine system version on time machine backups

I want to restore Leopard to 10.5.5 as I am having a lot of problems with Mail with 10.5.6. I did the Mail update but that didn't work and I had to reimport all my mailboxes and now I have a mess. I don't remember the date I upgraded to 10.5.6 so I would have to reinstall December 14th backup which is the first I have and I know that Apple released 10.5.6 on the 15th of December. but I may have installed it much later--is there any way to read the system version number off the time machine backups?

when you are using full system restore utility on the leopard install DVD it will display the OS version next to every restore point.

How can I restore my old iTunes Time Machine backup after upgrading to Mavericks?

I previously had Snow Leopard, and am wondering how I can simply restore ONLY my iTunes library from my Time Machine backup, last made only a few days ago when I had Snow Leopard. However, I seem to be unable to access anything backed up before I installed Mavericks. Any help would be great, because I'd hate to have to struggle to locate 160GB of music manually.
Many thanks!

Your choice really. Either way will work. Retaining the older backups gives you a way to restore older files. When I upgrade from 10.8 to 10.9, the backups continued without errors. Depending on what you upgraded from, in 10.8/9 you have the option to backup to 2 separate drives thus giving you some protection in case one drive fails. You can either copy the old backup to a new drive (Disk Utility/Restore seems to work best) or start a new one.

Trying to upgrade to Maverick but my disk has Time Machine backup so it cant and will not intall. How do I get around this problem?

I have a 13-inch MacBook Mid-2009 running on IOS X Lion and am trying to upgrade to Mavericks but after the download and starting installation the point where you choose which disk to use it says my hard drive is being used for Time Machine backups so it can not be used. I have turned off the Time Machine but do not know how to remove the backups from the hard drive. What do I do to get rid of the Time Machine backups I no longer actually need and install Mavericks? I have moved all my files to a separate terabyte hard drive but that drive does not have the GUID partition scheme to be used for installation. So I am stuck with one internal hard drive I cant use due to Time Machine and an external hard drive I cant use due to this GUID partition problem. How can I work around this and finally upgrade to Mavericks?

Since upgrading to Lion, my time machine backups are failing - error message: The backup disk image "/Volumes/Jackie Scanlon's Time Caps/Jacqueline Drabczynska's MacBook.sparsebundle" could not be accessed (error -1). Any ideas?

Since upgrading my Macbook to Lion, the time machine backups are failing - error message: "The backup disk image “/Volumes/Jackie Scanlon's Time Caps/Jacqueline Drabczynska’s MacBook.sparsebundle” could not be accessed (error -1)." I have rebooted the TIme Capsule and it worked OK, but don't want to do that every time. Any suggestions? Thanks

Any new info on this?
I had the exact same problem and went crazy and spent a hecka lot of time trying to deal with my brand new 2TB Time Capsule and almost brand new MacBook Pro. Then I thought I fixed it...and I tried SO MANY things, I don't really know what did it...except taking out any apostrophe's in names of stuff that Apple puts in there...BUT...now it's back.
Grrr...

Are files in "Latest" folder in Time Machine backup full versions

I need to transfer several gigabytes of files from a Time Machine Backup of an older iMac to a new Mac Mini. Can I just connect the external drive with the Time Machine backup on it to the Mac Mini, open the Backups.backupdb folder and copy all of the files in the "Latest" backup? Will these be full versions of the files? I spoke with a couple of Apple Support techs and one said that all of the backups were "threaded" together, thus my concern about getting full versions when I just drag and drop from the Backups.backupdb folder rather than going through Time Machine or Migration Assistant. The other tech said yes, the files in the "Latest" folder in the Backups.backupdb would be full versions, but I'm still not convinced.
Would prefer not to go the Migration Assistant or "restoring" through Time Machine. In some of my tests I wasn't comfortable with the way it worked.
Has anybody done this before - copying files directly from the Backups.backupdb folder rather than "restoring" through Time Machine?

Upgraded to Mavericks and time machine backups keep failing.

I upgraded to Mavericks a few days ago and now I find my time machine backups keep failing. I first tried turning off the power to the time machine then turning it on again and I managed to get one complete backup but that took over 20 hours to complete.
The time machine backup mode never seems to get beyond " preparing backup" then showing the message "backing up failed, disc already in use"
The time machine backup worked fine before I upgraded, is there a way round this problem or will I have to go through reloading the time machine as if it were a new piece of equipment?
My wife's iMac is still on mountain lion 10.8.5 and the backups on the same Time Machine work fine.
Any help would be gratefully received

Hi,
I have exactly the same problem.
MBP 2011 running 10.9 named "ebook"
MacMini running 10.8.5 server with TM share
everything works fine UNTIL for some reason the MBP is interrupted during a TM backup ...
After that I get the disk already in use error !
Rebooting the MBP wont help, but I narrowed the problem down ...
Looking on the Mini server I noticed :
- the TM backup user stays connected over AFP, even after several hours of inactivity and a couple of reboots of the MBP. Killing the AFP connection works, But problem stil continues !
- looking on the MBP with "lsof | grep ebook" showed me that the SparseBundles were still in use by the AFP process ... Using the Server control panel and restarting AFP solved that ...
After restarting the AFP process the remote TM Backup started to work again !
A couple of days later, the same problem occurred again, fixed it by this work around ...
I hope there will be a more permanent solotiun for this !

I am using I Photo 9.2.3 with OS 10.6.8 When I upgraded to current I photo some of my Iphoto books i put together disappeared. Cant find them anywhere, including in the time machine...I photo cant open older files...How can a find th book entitled "Mom"

I am using I Photo 9.2.3 with OS 10.6.8 When I upgraded to current I photo some of my Iphoto books i put together disappeared. Cant find them anywhere, including in the time machine...I photo cant open older files...How can a find the book entitled "Mom" ? Does Apple keep ordered books on file?

Apple keeps books for a short time (used to be 40 days. I've not seen a recent time frame)
What version did you have?
Books do nor exist except in the iPhoto database so you can not "find" a book vista TM. You restore a previous library (be sure NOT to overwrite your current library) and switch to it
