HT204476 So what happens if I accidentally delete the Migrated Aperture Library?

Just read the Help note on Apple's site about how Photos doesn't actually take up additional space on my hard drive. To be honest, that wasn't clear to me when I was looking around my Pictures directory this morning and I almost deleted the original Aperture Library.
What happens if I do?

I think I misread your question.
The way In understand it is that the hardlinks when associated with multiple folders result in more than 1 folder referencing the same files - so long as 1 folder is referencing the items the original files do not delete - where are they? - I suspect to the user that is hidden and if you get rid of Aperture library the original files stay somewhere in the file system but remain associated to the Photos library.
I agree for those of us who worry about things like this there's a concern we'll inadvertently delete originals, but I believe TD's advice is correct.
Either way, I would probably make a backup of any library I was about to delete to an external drive plus/minus Time Machine to be on the safe side.
Unless you really need to delete Aperture library might be as well just to leave it and ignore it until you're happy Photos does what you need.

TS2755 What happens if I accidentally delete messages

So i accidentally deleted messages of me and my best guy friend and i tried restoring my phone hoping they would come back but they didnt. is there anyway to get them back

Unless you had those messages in a backup, there is no way to restore them once deleted. You can try looking into third party computer programs that might help but there is no official Apple way.

Am I able to delete the "migrated photo library" after I convert from iPhoto to Photos?

I've recently converted to the new Photos app in OSX and have noticed there is a large library with the iPhotos library logo (52.1Gb). I'm wondering if I can safely delete this without losing any pictures from my Photos library. or if not, what is its purpose and why is it so large?
Here are some screenshots of an OmniDiskSweeper sweep of my home drive and of finder:
Any help is greatly appreciated as I have very limited disk space!

I have! And it seems that iPod cache is quite large. I think I'll go ahead and delete that and see if it reduces in size if I resync my device (I have reduced the amount of pictures I sync)
I have also deleted some files and events since trasferring to Photos (in an attempt to clear disk space). Would those changes reflect in the iPhoto library or is that a snapshot of my iPhoto library at the time of trasfer? I'm satisfied with my Photos library, so I may go ahead and delete the iPhoto one since its larger (I also have a backup on a drive of the full library before deleting)
Here is the memory distribution in both libraries:

/var is a hidden folder, so you mustn't remove the folder.
The only solution is to reinstall OS X. If you have OS X Lion or Mountain Lion, use OS X Recovery > http://support.apple.com/kb/HT4718
Hold Command and R keys while your MacBook is starting and reinstall OS X. You won't lose anything. If you have a backup, you can restore it after starting in OS X Recovery instead of reinstalling Mac OS X, so you will save a lot of time

Reinstall OS X.
Reinstall Snow Leopard without erasing the drive
1. Repair the Hard Drive and Permissions
Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. 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 installer.
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.
2. Reinstall Snow Leopard
If the drive is OK then quit DU and return to the installer. Proceed with reinstalling OS X. Note that the Snow Leopard installer will not erase your drive or disturb your files. After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.
Download and install Mac OS X 10.6.8 Update Combo v1.1.
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.

I accidentally deleted the Package Contents of Image Capture

I accidentally deleted the Package Contents of Image Capture. When I went to delete Image Capture itself it said I needed it. Not sure what for as I've never opened it.
What is it for?
If I do need it, can I just put the Package Contents back where they belong?
Where does it belong?
Help!!!

Your Mac has a Recovery partition instead of a disk, using it will let you reinstall OSX.
While they were in the trash you could have tried the 'Put Back' command but if you have moved them from the trash it is too late now. Please don't try things out unless you know what is going to happen.
And maybe you should take your Mac to an Apple Store.

HELP! I Accidentally deleted the iTunes folder in the My Music folder

HELP! I Accidentally deleted the iTunes folder in the My Music folder so I lost the two files
iTunes Library.itl
iTunes Music Library.xml
As I understand it, these files contain all the play counts, ratings, etc. and I've spent weeks getting this info the way I want it and don't want to lose it.
I have all my mp3 files on my desktop computer HD under a seperate directories, so I'm not worried about loosig origninal music files. I don't have iTunes copying the files when I add them to the library and I do have "Keep iTunes Music folder organized" checked. I have not relocated any of the original music files.
I have not auto synced my iPod, and I can open the iPod in iTunes and all my songs, with play counts, ratings, etc. are there. I just want to get the playlists, play counts. ratings, catagories, etc. back to my PC.
Is there any way to get the playlists, play counts. ratings, catagories, etc. from the data on the iPod and recreate the .itl & .xml files on my PC? I see there are many files on the iPod two of which look promising "iTunesDB" & "iTunesPlaylists".
Can someone please tell my how to recreate just the .itl & .xml files by using the info on the iPod itself? Again, I have not relocated or lost any of the original music files, I just want to get the playlists, play counts. ratings, catagories, etc. back that are stored in the .itl file.
I really don't want to have a software utility copy the info over as then I will have two copies of my music files and I've spent a lot of time organizing and naming the mp3 files just the way I want (not the way iTunes wants).
I've read many posts and it seems many have screwed up recovery by trying things without clear direction.
Thanks for the help in advance.

Try some of the more robust recovery/trnsfer programs. Several can recover the playlists, and metadata of the songs on the iPod. Do some reading on the respective websites.
These links will give you several methods of recovering whatever songs remain on your iPod; some free, some third-party software, some more comprehensive for restoring Playlists, Ratings, Play Counts, etc. Read them and their associated links before deciding on a strategy that works for you. There are many various third-party software programs that will offer a more robust process, or an easier GUI. Do a Google search for them if the links below leave you wanting…

iPodRip Software
PodUtil Software
Senuti (Mac OS X v10.3 or higher Recovery Utility)
XPlay (Software For Music Recovery &/or Cross-Platform Functionality)
XPlay Photo Browser (For recovering Photos)
After recovering your song files, strongly consider developing a thorough backup strategy for just this type of situation.
You need at least two full sets of your music, not including what is on the iPod:
-- One full set on the PC within iTunes (on internal HD or ExHD)
-- One full set on an separate external backup medium (CD/DVD/ExHD/other)
-- One (full or partial) set on the iPod
Music files on just the iPod and only one other medium is not considered having any backup.
If you cannot store your complete music files on the computer’s internal HD, then create and maintain at least two external sets (any multiple combinations of ExHDs, DVDs, CDs).
Backup both the music files and the Library database file (iTunes Library.itl). What are the iTunes Library files?

What does it mean by deleting the Content of the setup table when LO cockpi

Hi all:
what does it mean by deleting the Content of the setup table when LO cockpit ? why should we do it? why set up tables ?
Thank you very much!!!
Edited by: jingying Sony on Jun 7, 2009 4:46 AM

Hi Jingying Soni,
Data sources in LO cockpit have a seperate exctraction source during full update mode and delta update mode.
During delta update mode(when an transaction is posted in any particular application - like SD - sales orderm delivery) data is posted in application tables and updated alongside to the update table/extraction queue.
From the extraction queue this data is further transfered to the delta queue using periodic background jobs.The data is then upladed in BW. The delta lad always reads data from this delta queue.
However, when a full load is requested from the BW, the data is sourced by the set up table of the corresponding application.
The setup table is loaded/initalized first. In this initialization process , it reads data frm the corresponding application tables and stores it within this table. Later BW reads from this set up table whenever full/initial load is requested.
The process of filling set up able before full load request frrom BW is called set up run.
Before you run a set up to fill the set up tables you need to check that the set up table is empty.
If it is still containing data that was previously loaded in some other set up run. This data will als get loaded in BW unitinetionally/accidentally.
So, you need to ensure that you only get the intended data in BW. This can be done by proper selections to transfer data from application tale to set up table and from setup table to BW.
Along with this you hae to ensure that the set up table is either empty or you are using a disparate selection in the set up run and BW load which does not overlap with the previous set up runs data.
Hope it helps,
Best regards,
Sunmit.

I accidentally deleted the applications: Mail, Safari

I accidentally deleted the applications: Mail, Safari & iTunes from the launchpad. I also emptied the trash by accident.
Is there a way to reinstall these applications without reinstalling the Mac OS X?
Will upgrading to Mountain Lion resolive my problem?
What is the best solution?
Thank You,
Mrs_Yu

If Spotlight is unable to locate your apps, use the install disc that came with your computer to custom install. On screen directions will guide you. Once this is done, use Software Update to update Safari, iTunes and Mail if necessary.

[Solved]Oops, I accidentally deleted the "Beginner's Guide" wiki page.

It seems like everybody and their hot sister heard of this Beranger person except me
Update: can't say I checked any of his older posts but I guess I've seen part of his 'dumping linux' blog post -- most likely the one that 'angried' people and said sisters. I can only ask myself: what the big deal is? Who actually cares? Personally I never understood blogs nor the need to have them .. but it was my opinion that these unfortunate inventions were supposed to be destined for your friends (+sisters) to read. So I can't understand this: why does anybody else in the world -- care -- about what that guy uses/doesn't use? What makes him so important / such a(n) hero.

HELP! I saved a document. Copied the document. Went to delete some extra characters. Accidentally deleted the entire document. Now I can't find my document. When I open the saved document, the page is blank. Does Pages save copied text anywhere?

I saved a document. Copied the document. Went to delete some extra characters and accidentally deleted the text of the entire document. I did not save a blank page. I cannot recover the lost text. Please Help. I'm NEW to Pages.

Hi Jan,
Copied text (or other copied material) is on the Clipboard, but only until you copy something else or log out of your account. If you act before doing another copy, you can paste the copied material back into the document. If you don't act right away, you may still have a path back.
One of the most useful keystroke combinations on the Mac is the "Oops! key," as a friend of mine once named it. That's command-Z, also known as "Undo". In some applications it will let you undo only a single step, but in others, including Pages, you can do repeated undos, so it's not quite so essential that you act immediately on making an error. Undo, done via the Oops! key, or via the Edit menu takes you back one change at a time. You can't skip any steps, so to get back to the state before the accidental deletion, you'll have to undo any work you've done since then. The memory of what to Undo disappears when you close the document or quit the application.
At that point you're at the mercy of your backup plan. If you've had Time Machine running, you'll be able to enter Time Machine and go back to an earlier, saved version of the file.
All these are in addition to the steps Ian suggested above.
Regards,
Barry
PS: Best piece of advice I can give a new Pages user (beyond Backup early and often) is to download and read through the first few chapters of the Pages '09 User Guide, available through the Help menu in Pages '09. Mostly pretty easy reading, and will get you through the basics without much trouble.
