Can I trash "Previous Systems" after Archive and Install?

For details leading up to this question, please see my previous post entitled "Not recognizing password after OS install". Basically I want to know if I can throw out the "Previous Systems" folder that was created when I did an "Archive and Install" re-install of my OS.
Thanks.

For more information about the previous system folder and what is saved, you can check out Mac OS X: About the Archive and Install feature. Probably the most important piece of information is that the Previous System Folder contains a copy of the /Users folder. If you thought that something was missing from your home folder in the new system after the upgrade, you could copy it from the /Users folder. But, if you selected the option "Preserve User and Network Settings" when you did the Archive and Install, this should not be necessary.
Personally, what I would do is to leave the Previous System Folder be for a couple of weeks. If you don't find anything missing, then it should be okay to delete it.

Problem Deleting Previous System after Archive and Install

Earlier in my time with this wonderful iMac, I did an Archive and Install to try and resolve a slight problem. I read all the docs beforehand and knew it would save the previous system in its own folder and saw that I could likely delete that folder afterwards.
I have waited months since then, (almost forgotten about this folder) but have never had reason to want anything there, so today decided to delete it.
I dragged the entire previous system folder to trash and tried to empty trash. It deleted most of the stuff, but kept one package DownloadReader7.pkg complaining of locked files.
I have used Pacificist to look at the contents of this package and it says it is a receipt. It contains elements of Adobe Reader Download Manager.app
I have looked on my present working system and can not find an equivalent.
So two questions...
1. Is it safe to delete this package (if I knew how)?
2. If it is safe to delete it, HOW do I, when it appears to have locked elements when I try to empty trash?

It's safe to delete any files in the PSF.
Usually all you need do is press the OPTION key before selecting Empty Trash. If that doesn't work the next thing to try is restart the computer after you've dragged the file to the Trash. If neither works then visit The XLab FAQs and read the FAQ on resolving Trash problems.

How do I restore previous settings after archive and install?

I had to do an archive and install (with the box unchecked about users) on Friday after I had a kernel panic issue, but now I don't know if there is a way to restore my previous settings and access my previous files. I found the "previous system" folders, but it restricts my access to almost all of the folders, and I can't even find all of my music (iTunes) files or my stickies. I also can't find all of my bookmarks and internet settings. I'm totally panicked...there is a lot of information for my business that I really can't afford to lose. Please help me!

See the following:
http://docs.info.apple.com/article.html?artnum=107297.
The following can also apply to locating and moving data from a Previous System Folder. The "Home" folder will be /Users/shortname/ where "shortname" is the user account name you created.
Because you did not transfer the users accounts when you did the Archive and Install you may have created a new user account and password that is not the same as the one you previously used. This means the PSF has different permissions associated with it.
<font "size=+1">Folders You Can Move to Your new Mac
From the Home folder copy the contents of Documents, Movies, Music, Pictures, and Sites.
In your /Home/Library/ folder:
/Home/Library/Application Support/AddressBook (copy the whole folder)
/Home/Library/Application Support/iCal (copy the whole folder)
Also in /Home/Library/Application Support (copy whatever else you need including folders for any third-party applications)
/Home/Library/Keychains (copy the whole folder)
/Home/Library/Mail (copy the whole folder)
/Home/Library/Preferences/com.apple.mail.plist (* This is a very important file which contains all email account settings and general mail preferences.)
/Home/Library/Preferences/ copy any preferences needed for third-party applications
/Home /Library/iTunes (copy the whole folder)
/Home /Library/Safari (copy the whole folder)

Can't open Virtual Machines after "Archive and Install" of Snow Leopard OS

Hi all,
Please bear with me while I provide a bit of background info for my issue:
I just installed a copy of Adobe Photoshop CS5, during which I was actually forced to archive and install my Snow Leopard because of an installation error. So, I inserted my Snow Leopard disc and let the OS X installer do its thing. I remember, somewhere along the way, an admonishment that this process may somehow corrupt any virtual machines that may be installed, but throwing caution to the wind, I went ahead anyway.
Well, turns out it did indeed corrupt my installation of Parallels 6 somehow, and now none of my VMs work. When I open Parallels, and select File -> Open, then select whichever VM I want, a screen flashes so quickly I can't see it (I assume it says something like "Opening XYZ Virtual Machine"), and then.......nothing.
Thus far, I have tried to uninstall and reinstall Parallels 6 (using the KB article that directs you to delete a bunch of files via Terminal after running the packaged uninstaller) and I deleted my VMs and restored backup copies of them from several months ago.
I'm now at a loss - any ideas what I can do to get Parallels to function again? I don't know if somehow permissions were modified, or if there are any other particulars that the reinstall of Snow Leopard may have made to cause parallels to be unable to open my VMs.
Appreciate any advice in advance!

I think I would look at if you have the latest Parallels;
clone and backup your system and files before doing anything;
boot off 2nd hard drive and run Apple First Aid + (Disk Warrior or DG3 or TechTool Pro 5).
Always be prepared to be able to restore your system to prior point, that could even mean keeping 10.6.4 around for a month until you know 10.6.5 and 3rd party software and drivers all play nice together.
Bottom line: invest in two backup sets and methods; a copy of SuperDuper or CCC; and Disk Warrior.
I've used VBox, Fusion but not Parallels, plus Windows XP Mode, VHDs and VMs under Windows Vista/7.
I'd go back to ERASE and INSTALL and then do all your updates, then start on 3rd party with main packages first (CS5 and others). Off load, save, backup everything and anything you might need first of course.
Last but actually #1: a small 30GB OS X 10.6.5 drive volume (can take the 30GB from one of your backup drive is fine) so you can run the latest DU plus other system maintenance (DVDs get old, out of date, slow to boot, can't use Finder and other programs).

Restore "Previous Systems" after 'archive and reinstall'.

Hi,
Long story short, I moved a crucial file and couldn't reboot... so I performed an 'archive and reinstall'.
This failed the first time, and worked the second time.
Now I can boot (into a fresh install), I moved the file back into the correct folder inside the "Previous Systems" folder.
Is there any way for me to revert/re-bless/boot back into this 'fixed' "Previous Systems" install?

Neither one of those files should affect your system and should be automatically rebuilt when you restart. There's no need to move them back. If things work properly in a newly created admin user account, then I suspect further plist corruption in the original account and suggest the following:
While logged into the newly created admin account, backup the bad account's folder, delete the bad account, selecting the save data option, recreate the bad account using the same username/password combo, log out and back into the recreated original account. If the problem's solved, open the saved data dmg file in /Users/Deleted Users/, open the /Library/Preferences/ folder from the saved data, open the current /Users/restored account/Library/Preferences/ folder, and slowly copy plist files from the saved data folder to the current one that don't exist in it. Log out and back in to ensure there's no conflict and things still work correctly. Resolving conflicts or identifying corrupt plist files is a laborious process. Good luck.
See http://discussions.apple.com/thread.jspa?messageID=4703015 for more details on this process.

How do i find previous system after save and install mac os x

The title pretty much describes my question. Due to the fact that my machine was irritating slow, I re-installed the operating system Mac OS version 10.5.6.
I choosed the option 'save and install' and followed the prosedure. Afterwards, I got the message that the old system was in a newer version and that I had to upgrade the mashine before I could get hold of the old files. So I upgraded to 10.5.8, but still couldn't and can't find any previous system-map. I then transferred programmes and files from an old PoweBook G4, and the programmes seems to have been transferred all right, but documents are gone and the photos are not recognizable.
I regret doing the re-installetion! and wonder if its ever possible to recover files from the previous system.
Oops, I discovered another problem: The word-program doesn't function properly.

I've just had a look through the MindNode Pro support site, which did actually help (thank you), because it reminded me that Mobile Documents is in ~/Library. I was able to open iCloud files from the Terminal at least (once I remembered to add the .mindnode suffix). MindNode, however, brings up the same error as before. I tried using TextEdit to open a link to a TextEdit document stored in iCloud, and exactly the same thing happened.
I don't know why this happens, but it seems strange that you can open documents from Terminal in this way, but not from the applications themselves (or cross-application). I've just noticed that the error message I described in the initial post substitutes things like %20 or %22 for certain characters: could that be what's causing the problem, or is that just the way the link is displayed by the error itself?

Finder not responding after Archive and install

I recently encountered my first problem ever with my mac(new in '05) This is the first mac I have owned; I have worked on G3's and G4's in the past. After reading through many message boards and support pages I don't believe my problem to be similar but different to previous posts.
My problem started off with an OS problem that I was able to diagnose in the "help" book I purchased when Leopard came out. It said I should Archive and Install to remedy the problem and keep my files. I ran the archive the install (it gave me no options to preserve user or network settings). After Archive and install my computer started up alright, but I got the permanent beachball and the finder does not work. it is constantly non responsive. I can relaunch finder, but after it restarts it goes non responsive immediately once again. So I can't actually access my "previous system" folder to move anything over. I checked my dock items and finder, they opened, but my itunes asked for an update. I list of update items came up; I did the non-restart items first. they updated fine, (my itunes old itunes playlists are viewable but not playable now) then I did the items that required a restart. That is when I found out that I could not shut down or restart my computer with std. procedures.
Currently I can only access my spotlight or apple pull down menu if I am in a functioning dock program (safari or itunes, quicktime. etc.) after reading some more support pages it looked like the common thing to do was check permissions and verify disk. I did, I repaired two permissions and the disk was OK. I did look at the HD files, they were as I remembered, but unaccessible (greyed out) and the "previous system" folder was present. +It didn't look like I would expect. The HD looked same as it used to just with a previous system folder.+ After checking the permissions and verified the disk I tried a hard restart. It came back the same as before, unresponsive finder and only the few dock items worked along with spotlight. I checked permissions and disk verify again and everything was OK.
Sorry to be long winded I am trying to be thorough...In short, My finder does not work after doing an Archive and Install to fix my original problem (which has been fixed)...the remedy for an unresponsive finder is to do an archive and install. Is another archive and install really going to fix my problem? Can I archive and install OSX 10.4 and work my way back up to 10.5.6?
Secondly is there a way to restart my computer without doing another hard restart?

It won't let me add a new account. I am locked out and when I try to unlock it gives me the beachball and becomes non responsive after it tries to authenticate.
I looked at the log file, I am not sure what exactly to look for. I am no programer. I see an awful lot of negative wording. I see some errors like "error (-4956) locating menu extra but they are mostly under system preferences...I see some stuff in the loginwindow that says is not a full path... Otherwise, the only reference I see to the finder is when I have force quit the finder.

Recover mail after archive and install

Hey there good mac people,
I recently archived and installed on my ibook g4. It was successful, my problem is that I forgot to backup all the mail I had in my osx mail app.
The previous system folder (library<mail<mail accounts<com.mac.mailaccounts<English.lproj< file, but I don't know if this will help restore or not?
Some of the mail is still on the server, but it is set to delete from the server once a week, and thus only a weeks worth at best is still on the server.
Does anybody have any suggestions?
In the future, what's the best way to back up mail?

Hello art-is-work.
I don't understand your problem. Archive and Install should have preserved all your data, unless you told it to do otherwise. Did you?
Mail stores most preferences and all account settings in ~/Library/Preferences/com.apple.mail.plist. Everything else, including all your messages and mailboxes, is stored within the ~/Library/Mail/ folder.
If the problem is that you told the installer to not Preserve Users and Network Settings, then Archive and Install should still have saved a copy of your entire home folder in /Previous Systems/Previous System N/Users/, where N is a number. The old Mail folder and preferences file should be there. You can just copy them to the appropriate location of your current home folder, or follow the somewhat convoluted procedure described in the following article to safely restore them:

Note: For those not familiarized with the ~/ notation, it refers to the user's home folder.

Where is mail stored after archive and install?

Hello All,
I need to know where my old mails are stored after archive and install. To give a bit of background... This is a work computer. Its a MacMini which came with 10.4 installed. Before I joined the company boss upgraded to Leopard and thats what I have been using all this time. Recently it blue screened and I had to do an archive and install after trying various other options.
I only had the original install discs with 10.4 in them and not the Leopard discs. Since I needed to my computer up and running, I used those discs and did an archive and install.
I have all my old documents, etc but I couldn't open mail from the previous systems folder because its a different OS.
Is it possible to retrieve my old emails without having to install Leopard again?
Any help is appreciated.

When I started the computer up, instead of the login page with the account names coming up, there was just a blue screen. There are lots of articles that gave suggestions to try but nothing worked so I had to archive and install.

Cd inserted but unrecognized after "archive and install"

After "archive and install" OS X.2 and clicking on "save settings", everything works fine, except sound cds are not recognized when inserted. iTunes works fine with the original files on hard disk, but doesnt see the cd (it did before).
I repaired permissions. I deleted the "previous systems" folder. still nothing.
I did notice that the "previous systems" folder has an "audio" file in it but the current "system" folder doesnt. I tried copying this audio file into the current "system" folder but I get the notice that it cant be changed.
I need to hear cds on this computer. Any ideas?
(It isnt a speaker problem as the itunes files play fine).

Thanks, ali, but I did that early on. Didnt put it in the post. On insertion of a CD I have it set to open iTUnes.
I found a further problem which is that the midi set-up no longer locates my external keyboard. I will check the discussions under audio for this one, however. (I did check about the CD problem in the audio discussion but nothing there.)

Can I copy newer system (10.6.8.) from previous system folder after archive and install with (10.5.4)?

Rightyho,
had trouble with extensions in 10.6.8 and had to re-install with original disks 10.5.4.
Did an archive and install.
In my (dated) Previous System Folder are Appl / Library / System / User folders.
Copied my User folder back no problem.
Can that also be done with the newer system? No info in support.
Time Machine won't migrate because of newer system and I have only a disk image of Snow Leopard and can't burn double layer DVDs.
When I tried to order SL DVD from Apple they told me it'll take 3 weeks ...

After archive and install--I have a previous system folder

Hello, I had a corrupted system file and I had to do an archive and install, which used the system discs I got with my laptop to reinstall OS X.
Now I have a previous system file on my hard drive. Is this still needed? Can i just delete it? What can I do?
Thanks

This is simply an archive of your previous system.
Although system was corrupt, you may be able to look through the folder and retrieve any data which you would like to keep.
But the answer is no, you definately don't need it.

After archive and install, can you go back to old system?

After some trouble with permissions, I decided to do a clean archive and install from 10.2.8. Too late I realized that the install would be 10.2.
The permission trouble did not go away, and now I have additional trouble with upgrading everything, the combo upgrade to 10.2.8 does not work, error messages etc.
Is there a way I can undo this and use my old system 10.2.8 again which is saved in a folder?
Thanks.

Hiltraut:
As ali brown has already pointed out your iMac does, indeed, have 2 Firewire ports. Depending on which optical drive you have (the computer shipped with CD-RW, DVD/CD-RW, or SuperDrive) you can install Tiger directly.
Since you have an older version of Jaguar, and since it does not seem to be very co-operative, I suggest that you seriously consider upgrading to Panther or Tiger. To install Panther your computer will need to meet the minimum system requirements for Panther. You will need to purchase the Full Retail version of Panther.
To install Tiger your computer will need to meet the minimum system requirements for Tiger. You will need to purchase the Full Retail version of Tiger.
You can purchase universal installer versions of Panther, guaranteed to install, or Tiger on CDs, from applerescue. Please note that Computer specific or upgrade versions should be avoided since they are optimized for the computer to which they are specific and will therefore, very likely, cause problems during or after installation. On the legal side, it may be a violation of the Software License Agreement which statesThis License allows you to install and use one copy of the Apple Software on a single computer at a time. This License does not allow the Apple Software to exist on more than one computer at a time...
If you decide to go that route please post back for assistance with how to proceed.
Good luck.

How do I do back to previous system folder after archive and install?

Did an archive and install (retaining my existing user account), only to discover it was unnecessary. (Turns out the problem was hardware-related.)
How do I go back to using my previous system folder?

Huh. Hardly seems to be worth "archiving" if you can't go back to the archive.
The purpose of an *Archive & Install* is to install a fresh, known-good copy of the OS, while preserving in the archive all the files from the previous copy of the installed OS that you might potentially need for some reason. (This is why it is called an Archive & Install.)
However, since any of these archived files might have been damaged in some way since they were installed or created, or in some way conflict with a freshly installed OS, they cannot be considered "known-good" without further testing & should not be reintroduced haphazardly into the "live" system.
The value of this install method should be obvious if you consider that if the OS is sufficiently damaged it will not run the computer, either at all or well enough to recover from whatever damage is done. Without this option, you would have to erase the existing startup disk completely (with the *Erase & Install* method), losing everything created or installed besides what is contained in the OS installer.
The closest equivalents to the kind of archive that you can "go back to" are cloning the entire drive or using the 'restore from Time Machine' option from the installer DVD's Utilities menu, assuming you use Time Machine.

Previous System folder vs. system folder after archive and install

Hi there - I am very new to mac but love the products and am excited to be a part of the culture.
Because I am having battery-type problems I was told to do an archive and install to see if it was a software problem.
My question is, I followed the instructions apple gave for doing the archive and install. And it says that you can delete the previous system folder if everything is the same or you can move stuff over.
The problem is I want to delete the previous systems folder but it is very different than the new one and I don't even know what I would copy.
Briefly, the new system folder just has one folder inside called library with a bunch of folders inside of that.
The previous system folder called previous system 1 has folders entitled application, library, mach.sym, private, system, and users. Why are they different and what can I do?

The previous system, in most cases can be safely deleted. You can't revert to it anyway, so there's no fall back option to worry about. If you've saved everything in your user folder (or home folder - same thing) your data is safe. The previous system may have some preference files for apps you run, perhaps even registration data for apps that require serial #'s when you install them. If everything runs fine, and your data is where it's supposed to be, you can safely delete the previous system. I'd suggest making sure everything runs OK for a week or so, make sure all your apps work and all your data is there, then delete the previous system.
