How to back up before erasing yosemite

I'm going back to apple store next week and they are going to erase the computer to get off the yosemite and put back mavericks. They said i am going to lose some applications if i dont back them up. i saw the time machine in the support area and it said it backed up files but not applications that i could see. i had assumed i would be making an external back up. I'm not really sure what i'm suppose to do now. This is a second hand computer and i don't have any of the codes/eceipts/etc for the applications that were purchased. Any suggestions or recommendations? i am a very
new mac owner, had only used it a month or so before i unfortuantely upgraded to yosemite.
also i had started a post a few weeks ago about yosemite and don't know how to find those or keep them bookmarked. i would have added this to those if i could have
thanks Claudia

Mail will not recognize mailboxes backed up before erase and install.

Since my computer was starting to slow down, I figured it was a good time for the old erase and install. Rather than backup the whole "Mail" folder in the library as I should have done, I only backed up the "Mailboxes" and the "POP-address@..." folders. I also backed up the plist folder to go in /preferences/mail.
Now mail won't recognize my old mailboxes. The preferences list clearly worked, and my mailbox folders even appear on the left in mail, but none of my messages are there. When I try to use the "import mailboxes" command in mail, it says that "No valid mail for mac os x were found." The messages are clearly in these folders because if I double click on an individual message, I can see it.
Please help me to get back to my former world. I miss IMAP.

This doesn’t make sense. com.apple.mail.plist, if that’s what you mean, is a file, not a folder, and it should be in ~/Library/Preferences/, not in “/preferences/mail”.
When I try to use the "import mailboxes" command in mail, it
says that "No valid mail for mac os x were found."
Pay attention to the instructions that Mail displays when choosing Mail for Mac OS X as the data format. In the next step, Mail wants you to select the folder that contains the mailboxes to be imported (i.e. the folder where the .mbox folders to be imported reside), not the .mbox folders themselves nor the Messages folders within them. If you select the wrong folder, Mail says “No valid Mail for Mac OS X files were found” because it cannot find any .mbox folders within the folder you’re selecting.
Yes, sorry, the file is in library/preferences.
Your suggestion about paying attention to the folder that the mailboxes are IN worked like a charm. The only problem is that now I accidentally deleted my trash mailbox and can't figure out how to create a new one.
Thank you so much for your help, and I apologize for my ineptitude.

How to back to maverick from Yosemite

I have iMac2008 & 2007. In 2007 I still have Maverick but I have changed the 2008 to Yosemite.
I would like to transfer Maverick from 2007 to 2008 iMac because ever since I changed to Yosemite my computer crashed.
Therefore; I would like to go back the 2008 Mac to Maverick.
Is anyone know that I can do that?

if the recovery disk is already at Yosemite it will restore it to Yosemite.
if the mac was originally purchased on mavericks if you do an internet recovery then it should revert back to the os that it was originally purchased with this can be done by holding command + option + r
it will boot into internet recovery and follow the process the same from there

How do I know my contacts have been backed-up before I update to the new software? i tunes tells me I have to erase and restore, I'm afraid of loosing contacts.

How do I know my contacts have been backed-up before I update to the new software? itunes tells me I have to erase and restore, I'm afraid of loosing contacts.

you can sync your contacts and things under your own itunes and your wife can have her own... or both in one as long as you have it synced in the same computer they will be there
if you name ur phones its easier to tell which is which
my husband kids and i all have our names and then iphone next to it and it creates a different backup for each and then we update and we restore from there it lets you choose which backup you want...
hope it helps!!

I was syncing everything to itunes and I tried to do my contacts, not knowing quite how. I ended up erasing all of them from my phone without any of them syncing to my computer or itunes. Is there any way I can get them back? I really need them all.

There are lots of ideas floating on the web for this particular issue - all of which I tried. I had the same problem and it turned out to be my USB cable. I thought the cable was fine as it would charge my phone and play but the data transfer pin was bent. I replaced the cable and it fixed the problem. Worth a shot as it is an easy fix!

IMac will not start-up, do not have a backup, any way to back it up before erasing the drive?

Our iMac will not start up, it goes to the flashing question mark screen. I have tried the different steps listed at http://support.apple.com/kb/TS1440, but they have not worked, as it says the disk is not repairable. It says I need to erase the disk and reinstall OS X. However, I do not currently have a back-up of the hard drive, so is there any way I can back it up before erasing and reinstalling, even though the iMac will not start up? Thanks.

I also tried downloading Snow Leopard onto an external hard drive and boot from there, but it just comes up to the choose a language screen everytime.

When i update my IOS7 i lost my all pic from my IPAD2 how to get back those pic? and i don,t think so i did kept back up before i did that. can anyone help me for this issue?

When i update my IOS7 i lost my all pic from my IPAD2 can anyone suggest how to get back those pic? and i don,t think so i did kept back up before i update ios7. can anyone help me for this issue?

The photo's in your camera roll would be in a backup, if you have one (iCloud or iTunes). If you did not keep a backup somewhere, they are gone. Sorry, but that is the way of any data - if you don't have a backup of it somewhere, there is nothing to restore it from.
All other photo's should be on your computer somewhere anyway - whereever you had them to sync to the device originally.

Typically, How many back and forths with Creative Support before they acknowledge your questi

Typically, how many times does one have to go back and forth with Creative Support before they acknowledge an issue or question?
This is ridiculous.
I'm on the forth reply now.
All I want to know is if there is a?64-bit ASIO driver for the X-Fi Titanium on 64-bit Vista?
They will not answer me.
All of my testing indicates that there is not a 64-bit ASIO driver for Vista, but they will not confirm or deny.
:angry:

dRe: Typically, How many back and forths with Creative Support before they acknowledge your question?U I don't know what Creative would have written if you asked SUpport these days?
I assume, they lied when they wrote this. There are several walkarounds for XFI cards
with beta drivers. In releas drivers they exclude the ASIOx64, but in beta it's included!
Creative has a very awkward marketing strategy. This was with Vista not having EAX on Audigy as
the said it is impossible. The newer X-FI was able to?do it and after a few weeks the Audigy also could-
after paying for it. The same with DolbyDigital Li've... and now with x64 ASIO. They reduce features
in cases the cheaper card had same possibilities as the more expensi've EMUs...
Shame on them. I?baught a creative Card for the 4th time (SB, SB AWE32,Audigy2, and now Titanium).
I'm going to thinking about selling it...

How to delete photos that i backed up before in all of my devices?

How to delete photos that i backed up before in all of my devices?

Same way they got there, through the iTunes sync process. Your phone connected, iTunes running, under the Photos tab, remove the check marks next to the folders/albums you don't want on your phone, hit the apply/sync button.

How do I restore text erased from a .txt document, named and saved frequently, and on Yosemite OSX?

How do I restore text erased from a .txt document, named and saved frequently, and on Yosemite OSX?

1. I have no reason to doubt it, the task is pretty simple.
2. You should realise that these are not rewrites but progressions. PDF 1.7 adds just a little to PDF 1.6, and so on. Early versions of Acrobat would always update the version number to the latest version, whether or not they needed to do so. More recent versions have got smarter. Sounds as if XI is smarter still and is writing the version number actally needed rather than just the highest number it knows. People have strange ideas about PDF version numbers and sometimes want to do things like "open and save in the latest version" but this is not just useless but meaningless.
3. In many cases the first line of the PDF contains the version number (but not the extension number), but this need not be accurate as a later piece of information (much later and harder to find) can override it.

You can't. If there was a way to get into the phone and backup data without a passcode, what would be the purpose of the passcode?
Either think harder, or prepare to lose all your data.
