Migration: Can I use Time Machine to move apps from MacBookPro to MacPro?

I've outgrown my laptop and have "graduated" to a MacPro <insert big smile>. I know I can use Time Machine to bring everything from an old laptop to a new one, but can I do the same to bring files from the laptop to the MacPro?
Sure would be lot easier than re-installing everything.
I have the original discs for all the important stuff, but wondered if I could bring over those myriad apps that I've downloaded.
The laptop is being "retired" - the screen is getting darker and darker - soon will be unusable...

The first time you boot your new Mac is the best time to migrate everything in "Setup Assistant".
If it's not the first boot, funny things happen. For just the applications I'd use Migration Manager to get them from the TM disk, or from your connected laptop. Since you've already booted up I wouldn't try to migrate in your Home folder that way.
For your own data you can drag to copy, or for application support data here's a user tip for that.

HT1178 How can I use Time Capsule to move music from one computer to another?

I want to move all the music I have on my old laptop (macbook) to my new macbook pro. How can I do this? Easy, simple, steps would be greatly appreciated!

Are you moving the itunes library?? That is entirely different to moving just music.
Apple have specific instructions for moving libraries..
And there is no need to use the TC.. other than as a switch and router.. share the folder in one Mac to copy to.

How can I use time machine to back up and play media?

I just bought an external hard drive that I wanted to back up some media files onto (music and photos). I also want to stove videos/movies on the hard drive and play them from there. A few questions:
1. Is that the same as backing up with time machine or is it referred to as something else?
2. Can I use time machine to add new files, or should I do that manually?
3. Once the files are on my hard drive, can I remove them from my computer or should I keep them there?
I know that these questions may seem obvious, but I'm concerned about losing files because I don't understand what time machine actually does. Please feel free to ask me questions if you need to understand my question better. Thanks!

Time Machine makes a backup of your hard drive, which you can restore from, but not use as a repository of data.
Time Machine automatically makes incremental backups as you change things on the Mac HD.
Time Machine is not an archive, meaning if you make a backup, and then delete the originals from your Mac, Time Machine will eventually delete the copies it has made.
However, if you copy the files directly to the external, then you can remove them from the computer. But, those will be your only copies. If that disk dies, they'll be gone. So, that's really not a backup. It's the only source.
You can back up to Time Machine and also store other files on the same disk.

Can't use time machine due to corruptness even after reinstalling snow lepoard how to fix?

Yes, someone stole my original apple id in 2009. Now i bought another iphone in late 2012 , Created another apple id due to Apple not being able to help me access my original apple id. Which now since 2 months ago someone or company, or bank stole my second apple id. My iphone 4s with Sprint has no celluar connection supossedly due to no internet that is what sprint said but I looked it up on apple and it stated that there is a cellluar block on my iphone4s.
So I guess I will have to go in person to Sprint so they can explain that to me and why I was lied to on the phone earlier. Back to my 2nd stolen apple id that I registered my macbook,airport express router, and iphone4s and apple TV. So who ever stole this apple id obviously took over all my mac products I had registered to it. Enough about that back to trying to use time machine....Everytime i do, my macbook just starts acting all screwed up. I bought a WD external drive for Mac but I believe someone must have claimed it too. Since there is 75gb on it that I can't access. Kind of like my Macbook stating I can't save or have access to the Root . That is another thing after reinstalling snow lepoard which works great until I update it. Which is a problem because everytime I update it to 10.6.8 All the permissions are changed the graphics look horrible and I get redirected so bad its not funny. The email account is a joke. Also I notice my stationary for email is in Spanish not sure why and on Iworks the document samples are also in spanish. Now I dont speak any other language except ENGLISH AND HAVE LIVED IN UNITEDSTATES MY ENTIRE LIFE. But my internet provider Fibrant which swears they are local shows it is in the UK also when i try to access my email for that account it states it is not safe , certificate is expired and someone might be trying to impersonate my server. Needless to say it is getting old. I had this same problem with Timewarner and Att except att would just remove my ethernet driver then laugh when i would call and ask what the problem was. Then later I find out when I had DSL that somehow the phone number they had listed was change to being a digit off from my DSL account which again they laughed and thought it was funny. Enough about that. I need to know how to get access to my Apple id. I gave up on the first one but the second one I did have access to until I registered all my apple products. What is up with every thing I have with a usb port being corrupt. I have also notice anywhere in town where I live my phone is English until I come home it is arabic,hebrew , spanish any language except English. Shouldn't I be safer in my home??????????????? But I am not I am safer in town or anywhere but my home. EVerything states international in my home and this has been going on since 2009.....No one can tell me why. My power from Duke reads that OTHER Is costing me the most $$ every month what ????? This is a joke. But yet no one can tell me why or how to fix the problem. Going on 5 years , I have been cut off from everyone I know. Can't keep contacts on a phone or email accts. They all disappear. All so I am in Eastern time zone but all my computers and tv seems to think I am in pacific timezone. No one can fix this problem either. So if anyone has any suggestions on how to fix at least one of my 5 year problems I would be grateful. I try to create a new email account but either I am locked out right after or someone turns it into an alias account which doesn't help me. When I was layed off in 2009-2010 I went back to school/college. Needless to say they took my School email acct too.
Back to my iphone 4s problem. My icloud email account gets alot of spam starting about 2 months ago and I can't stop it. I try to foward it to Spam @ me but it hasn't helped.My iphone can only connect to the internet with wifi. Sprint swears that there is not a block but according to apple there is.
About my macbook and apple ID how can I upgrade my Macbook from 10.6.3 to 10.6.8 with out all the permissions being changed and corrupt?? I have tried several times and it is always the same. I won't to connect my iphone to itunes to try to restore it but it states I have to update it to 10.6.8. When I do that my computer is alot worse off. Also how can I use TimeMachine with out my Macbook getting messed up? Something in my house has taken over anything with a usb port actually years ago and probably now something kept turning all my computers and phones or any electronic I owned it to a printer. I actually can't even use a printer in my home thats the funny thing. When I try to connect one when I used windows it stated I had no rights to it and couldn't use it. Since I switch to Mac not much better. When I try to print a test page it is all crooked and too small of half off the page. So it is upsetting that I can't use a printer but something keeps turning all my electronics into printers. If anyone knows how to fix this problem that would be great or to stop all this international stuff going on in my home that would be wonderful. I try to buy brand new pcs but soon as I start them up something had already taken over. This is with nothing electronic in my home on. Turn everything that a power switch off or unplugged it. Still I lost rights and access to anything in my home. Now if I am away from my home and try to use one of my laptops they look completely different and almost usable. Unfortunately I can't afford to move. I thought about it but I am still in bankruptcy and don't have the money. In the last 4 years I have not been able to reinstall in backups that I have created. Not sure why oh wait it states I have no rights to do that. My macbook I lost access to a week after I bought it and connected my iphone too. You don't know how many times I wish I had never backed my iphone 4s to my Macbook. Right after I could not log into it. Even used the disk to reset the password nope still couldn't log into it. Try to type the formula for resetting the password and nope it didn't work either.
Any suggestions would be appreciated---Need to gain access to my apple Id that would be a great start

If you look at the User Tips tab, you will find a write up on just this subject:
https://discussions.apple.com/docs/DOC-4053
The subject of buying/selling a Mac is quite complicated. Here is a guide to the steps involved. It is from the Seller's point of view, but easily read the other way too:
SELLING A MAC A
Internet Recovery, and Transferability of OS & iLife Apps
Selling an Old Mac:
• When selling an old Mac, the only OS that is legally transferable is the one that came preinstalled when the Mac was new. Selling a Mac with an upgraded OS isn't doing the new owner any favors. Attempting to do so will only result in headaches since the upgraded OS can't be registered by the new owner. If a clean install becomes necessary, they won't be able to do so and will be forced to install the original OS via Internet Recovery. Best to simply erase the drive and revert back to the original OS prior to selling any Mac.
• Additionally, upgrading the OS on a Mac you intend to sell means that you are leaving personally identifiable information on the Mac since the only way to upgrade the OS involves using your own AppleID to download the upgrade from the App Store. So there will be traces of your info and user account left behind. Again, best to erase the drive and revert to the original OS via Internet Recovery.
Internet Recovery:
• In the event that the OS has been upgraded to a newer version (i.e. Lion to Mountain Lion), Internet Recovery will offer the version of the OS that originally came with the Mac. So while booting to the Recovery Disk will show Mountain Lion as available for reinstall since that is the current version running, Internet Recovery, on the other hand, will only show Lion available since that was the OS shipped with that particular Mac.
• Though the Mac came with a particular version of Mac OS X, it appears that, when Internet Recovery is invoked, the most recent update of that version may be applied. (i.e. if the Mac originally came with 10.7.3, Internet Recovery may install a more recent update like 10.7.5)
iLife Apps:
• When the App Store is launched for the first time it will report that the iLife apps are available for the user to Accept under the Purchases section. The user will be required to enter their AppleID during the Acceptance process. From that point on the iLife apps will be tied to the AppleID used to Accept them. The user will be allowed to download the apps to other Macs they own if they wish using the same AppleID used to Accept them.
• Once Accepted on the new Mac, the iLife apps can not be transferred to any future owner when the Mac is sold. Attempting to use an AppleID after the apps have already been accepted using a different AppleID will result in the App Store reporting "These apps were already assigned to another Apple ID".
• It appears, however, that the iLife Apps do not automatically go to the first owner of the Mac. It's quite possible that the original owner, either by choice or neglect, never Accepted the iLife apps in the App Store. As a result, a future owner of the Mac may be able to successfully Accept the apps and retain them for themselves using their own AppleID. Bottom Line: Whoever Accepts the iLife apps first gets to keep them.
SELLING A MAC B
Follow these instructions step by step to prepare a Mac for sale:
Step One - Back up your data:
A. If you have any Virtual PCs shut them down. They cannot be in their "fast saved" state. They must be shut down from inside Windows.
B. Clone to an external drive using using Carbon Copy Cloner.
1. Open Carbon Copy Cloner.
2. Select the Source volume from the Select a source drop down menu on the left side.
3. Select the Destination volume from the Select a destination drop down menu on the right
side.
4. Click on the Clone button. If you are prompted about creating a clone of the Recovery HD be
sure to opt for that.
Destination means a freshly erased external backup drive. Source means the internal
startup drive.
Step Two - Prepare the machine for the new buyer:
1. De-authorize the computer in iTunes! De-authorize both iTunes and Audible accounts.
2, Remove any Open Firmware passwords or Firmware passwords.
3. Turn the brightness full up and volume nearly so.
4. Turn off File Vault, if enabled.
5. Disable iCloud, if enabled: See.What to do with iCloud before selling your computer
Step Three - Install a fresh OS:
A. Snow Leopard and earlier versions of OS X
1. Insert the original OS X install CD/DVD that came with your computer.
2. Restart the computer while holding down the C key to boot from the CD/DVD.
3. Select Disk Utility from the Utilities menu; repartition and reformat the internal hard drive.
Optionally, click on the Security button and set the Zero Data option to one-pass.
4. Install OS X.
5. Upon completion DO NOT restart the computer.
6. Shutdown the computer.
B. Lion and Mountain Lion (if pre-installed on the computer at purchase*)
Note: You will need an active Internet connection. I suggest using Ethernet if possible because
it is three times faster than wireless.
1. Restart the computer while holding down the COMMAND and R keys until the Mac OS X
Utilities window appears.
2. Select Disk Utility from the Mac OS X Utilities window and click on the Continue button.
3. After DU loads select your startup volume (usually Macintosh HD) from the left side list. Click
on the Erase tab in the DU main window.
4. Set the format type to Mac OS Extended (Journaled.) Optionally, click on the Security button
and set the Zero Data option to one-pass.
5. Click on the Erase button and wait until the process has completed.
6. Quit DU and return to the Mac OS X Utilities window.
7. Select Reinstall Lion/Mountain Lion and click on the Install button.
8. Upon completion shutdown the computer.
*If your computer came with Lion or Mountain Lion pre-installed then you are entitled to transfer your license once. If you purchased Lion or Mountain Lion from the App Store then you cannot transfer your license to another party. In the case of the latter you should install the original version of OS X that came with your computer. You need to repartition the hard drive as well as reformat it; this will assure that the Recovery HD partition is removed. See Step Three above. You may verify these requirements by reviewing your OS X Software License.

Can I use Time Machine to back files on an External Hard Drive

My MacBook Pro hard drive filled up with movies, pictures, and music, so I bought a 2TB Time Capsule. I have a external hard drive that is about the same capacity as my MacBook hard drive. Sine the Time Capsule is by far the largest drive I have, I moved all my movies, music, and pictures to the Time Capsule and am using it as an external hard drive. I attached a 500GB external hard drive to the Time Capsule and I use that as the backup drive for Time Machine. However, the problem I am encountering is that I can't seem to direct Time Machine to include all of my files on my Time Capsule in the back up on to the other external hard drive.
Can I use Time Machine to backup data that I store on my Time Capsule to a external hard drive? If not, what is hte best method for backing up my files that are on my Time Capsule?
Thanks,
David

You need to use a different utility .. eg CCC or Chronosync to backup from the TC to yet another drive.. the problem is, that drive should be connected to the computer.. if you use a USB drive on the TC.. the file copying will be slow as slow as you will not believe.. all files are copied to the computer, then back to the TC.. it cannot copy directly to the TC..
As Neil said.. one way or another you need to use an external drive on the computer, even if you don't use it all the time.. the danger of course is not doing regular backups.. and forgetting their importance.
A true NAS will have automated backup incrementally of the files stored.. The TC is not a NAS in that sense.. it is a backup target for TM above and beyond anything else.

I have a powerbook G4 with macosx10.5.8 (as far as I know the latest possible OS with powerPC). Can I use Time Machine to restore my data on an Intel Macbook?

I have a powerbook G4 with macosx10.5.8 (as far as I know the latest possible OS with powerPC). Can I use Time Machine to restore my data on an Intel Macbook?

Well the newer TimeMachine model as stated in current Support pages isn't directly compatible on OS X 10.5 now, as noted in above link provided.
What OS X does your newer MacBook have running in it? (Not linux?)
With the current setup you have there may be a way -among other details in the support page- to do the migration of data from Mac, including a subnote on Time Machine, in a section below the main article with triangle by it, from links here:
•OS X: How to migrate data from another Mac using Mavericks 10.9:
http://support.apple.com/kb/HT5872
•OS X: How to migrate data from another Mac using Mountain Lion 10.8 and Earlier:
http://support.apple.com/kb/ht4889
In the support articles there are various troubleshooting and help items about the technology, some data back some time and whatever still stands would be there. Some archives are no longer current and say so.
Perhaps someoone still using older PPC Macs and Leopard 10.5, will say how to backup into a G4 PowerBook, from a Time Machine.
Unless the TimeMachine backup from the older PPC G4 PowerBook is used in the migration process of transferring personal account files from there to a new MacBook running (?) OS X. This probably could be done. You may be able to access older libraries, such as iPhoto, iTunes, etc and import them from the archive, to a newer Intel-based MacBook.
Sorry for any confusion.
I'll more carefully reply in the future.
Good luck & happy computing!

Can I use time machine to get rid of Lion?

Lion has been a total disaster for my iMac. After installation, everything went very buggy very quickly. Now it is freezing every few minutes. I just want rid of it. Can I use time machine to restore the old system? If so, how? Will my files be OK? thanks.

I point you to Pondini's TimeMachine restore page however you should also printout my instructions as something may go wrong and you need to do it the hard way.
http://web.me.com/pondini/Time_Machine/14.html
Back to Snow Leopard from Lion install method
Read and print out these instructions, your computer is going to be offline and you wil be cutoff from help until your machine is restored.
Clear the Desktop, Downloads and Trash of anything you wish to keep by placing their files in the respective Documents, Music, Pictures, Movie folders.
Disconnect other drives except the sole backup drive.
Backup ALL your Users folders (Documents, Pictures, Movies, Music etc) manually (drag and drop methods) to a (not TimeMachine) external powered drive (HFS+ journaled formatted in Disk Utility) and disconnect, your going to be wiping the entire boot disk of ALL DATA.
(warning, everything will be gone and not recovered, OS, programs, files, Windows etc all gone.)
Note: You might want to hold c and boot off the 10.6 installer disk and use Disk Utility to format the new blank external drive instead of using OS X Lion if that's hosed. Then reboot into Lion and copy files, may be safer that way.
Here we go!
Hold c and boot off the 10.6 installer disk that comes with your computer and second screen in just STOP there, don't install OS X yet.
Look at the Utilities Menu for Disk Utility.
On the left is the name of your hard drive maker, click it and Erase (format HFS+ Journaled), give it the same drive name as before, and click Erase...
(note: if you want to "scrub" the drive of old files that haven't been overwritten yet, then use the Security Option > Zero Erase, takes a lot longer)
This should wipe the drive of ALL partitions (GUID, OS X and 10.7 Recovery, Windows if present)
When it's done, quit and install OS X 10.6. Then install all your programs from fresh sources and validate/update.
When you setup a first account, use the same user name as before, this way you can simply drag and drop the content of your previous Users folders from the external drive right back into the new Users folders and everything should work peachy. Links in iTunes to music, playlists and iPhoto links especially.
Update OS X to 10.6.8 using the Combo Update for best results.
http://support.apple.com/kb/DL1399
(Note: If your original machine had 10.5 and you want the free iLife that comes with the disks with the computer, then you'll have to install 10.5 first using the same c boot/erase/format methods as above, then update to 10.6 via the disk, then Combo Update 10.6.8)
Final step optional but highly recommended.
A lot of people use a Carbon Copy Clone of their boot drive to a new HFS+Journaled external drive (used only for this purpose) as a "hold the option key" bootable backup in case something goes wrong with their boot drive or need to restore to a previous OS X version.. (in addition to TimeMachine drive for more immediate backups.)
It's not advised to have a Bootable Clone and a TimeMachine partition on the same external drive, as two drives gives hardware protection in case one fails.

How can I use time machine to recover my iWeb09 files?

I read that iWeb stores one's website pages in the domain folder which can be located at ~/Library/Application Support/iWeb. Can I use time machine to recover my iWeb09 files? If so, how? -I tried. I entered my Time Machine back up, and went back in time and brought the domain file forward but it opened only my current site pages, not the ones I am trying to recover. And it says the Domain file was last modified in October 2007 which is crazy because I've been using iWeb a lot and have published many pages. It seems like the uncorrupted pages, which I am trying to recover, existed somewhere on my computer at one point in time and space, less than a week ago, becuse I just published my site to a new hosting service since Apple will soon stop web hosting. So why can I not find them using time machine?

I continued searching and read another person's advise to down load an app named "Find File," then search for .sites. She said spotlight doesn't always find all files. So I did and sure enough, when I searched for .sites I found another Domain package, which I have no idea how it was created but which, it ends up, was the one actually being used by iWeb. So I went to that package then did the time machine and went back to before my web pages became corrupted. I had to delete corrupt blog pages out of my website menu to get iWeb to upload the other page changes even to a local folder.
So I went to that newly found Domain, went back in time, then brought that forward and as you pointed out the domain package had the parts of the pages, the files and jpegs, but not the structure/layout of the pages. So, I guess I gave up on finding the old pages.
Those pages still exist on the Apple hosting server but iWeb doesn't not reverse publication. Cyberduck would bring back the files and bits and peices but again not the pages as a total entity. I'm preparing for the end of Apple website hosting (next month?) and am republishing my old site. I decided to use a new domain name. So my entire original site is still totally intact on the web under the original domain name, on my mobile me site, I guess it will be there till sometime in June?
My problems started when I tried to publish my website to the new server. It just would not publish the whole website in one session. So I decided to do it a few pages at a time. Some pages went up, but as I added more, for some unknown reason the, blog pages, (about 70 subpages), which had aleardy uploaded just fine to the new server, became corrupt and locked up iWeb. Of course once I deleted the corrupt pages I didn't want to continue publishing the site to the host until I found and reinserted uncorrupted pages, knowing publishing changes would delete the already published pages.
At first I thought it was the hosting server's fault, but when I discovered that it wouldn't publish even to a local fold I was able to locate the cause within iWeb, deleted those pages then tested by publishing to a local folder. iWeb worked locally, so I knew I had found the problem pages. Well this is way more than you wanted to know. Thanks for your advise but I'll just start the blogging pages over.

Can we use Time Machine to back up data on Time Capsule from the outside of network?

I have Time Capsule at home. Can I use Time Machine to back up data of portable nootebook when I am working at office?

If you mean over the internet, you can but it will be so slow and more than likely so unreliable it is a poor method to use. Remember all internet is limited to upload speed.
Lion does a temporary backup onto local hard disk.. which is useless of course if the hard drive is damaged.. but helps if you delete an important file. Then when you go back home and it discovers the TC is available it will then backup again from where it left off.
I think it is only a major issue if you are away from home for major lengths of time, weeks or months.

HT201250 Can I use Time Machine on two different Macs to back up to one external drive?

Can I use Time Machine on two different Macs to back up to one external drive?
I have one 1T Western Digital backup drive that works well with Time Machine and my MacBook Pro. I now want to back up my wife's MacBook Air using Time Machine on her Mac and want to know if I can use the same WD external drive or if I need to get a 2nd back up drive? If I can use one external drive for the two Macs do I need to do something special on the drive or will Time Machine do it automatically?

Yes. You will need to configure Time Machine preferences on each computer to backup to the same drive. Note that you cannot connect the backup drive to both machines at the same time.

I am going to buy a bigger hard drive. i am operating on Lion. how do i install my os on the new disk? i can't use time machine.

i am going to buy a bigger hard drive. i am operating on Lion. how do i install my os on the new disk? i can't use time machine.

Plug this new drive as an external drive, boot from lion recovery "command-R" more info here: http://www.apple.com/macosx/recovery/
Open disk utility, format and partition the disk at your will (allways Mac OS plus...) and go ahead with the install, don't care if it tells you to whait thousands of hours, I did get installed in 2 hours and a half last week.
If you can't plug the disk as an external one, you'll have first to do an USB disk recovery utility, as easy as download the recovery utility and install it in an USB disk, you can find anything from the link above, plug the disk as a single master, and boot from the USB you created before.
Tell me how it went!!!

Can I use time machine to back up via a hard drive connected by USB to a HomeHub router?

Can I use time machine to back up via a hard drive connected by USB to a BT HomeHub router? Is there a better way to back up and store files than via the USB port on my new MacBook Pro? I'd like storage to be accessible from my earlier version MacBook too.

I think you want to make backups without connecting a hard disk via USB. In other words, you want to have the data storage be shared in your home wirelessly.
If this is the case, I recommend using a Time Capsule.
Time Capsule works great with Time Machine. You can set up all your devices to automatically make backups on the Time Capsule wirelessly and effortlessly.

Can I use Time Machine to retrieve mail that was in Trash on my MacBook Air, after I emptied Trash?

Can I use Time Machine to retrieve mail that was in Trash on my MacBook Air OS X Yosemite, after I Emptied that Trash?

Interesting question. I don't think you can because Time Machine would have deleted the data in subsequent backups because it was removed from the computer. But you never know about these things until you actually try it, which I've never done. So, why don't you give it a try. Worst that can happen is it's not there and you're no worse off than now.
If you need help with restoring mail from Time Machine: Please visit Pondini's Time Machine FAQ for help with all things Time Machine. Also open Mail and select Mail Help from Mail's help menu. Search for 'restore mail' and see if you don't find some instructions there, too.

I am trying to get an answer to whether or not I can successfully use Time Machine with an external HDD connected to an airport extreme? Some forums say yes, some say no.

I am trying to get an answer to whether or not I can successfuly use Time Machine with an external HDD connected to an airport extreme. Some forums say yes, some say no. I'm also curious about formatting the hard drive to work both on my wife's MacBook Pro and my PC. Any help would definitely be appreciated.

You may be going on a recollection, that I share, that at one time Apple stated this would be possible:
In fact, Apple’s Time Machine Web page touted this very capability as recently as last Tuesday, as you can see from Google’s October 16 cache of the page
Effortless meets wireless. With a hard disk connected to your AirPort Extreme Base Station, all the Macs in your house can use Time Machine to back up wirelessly. Simply select your AirPort Disk as the backup disk for each computer and the whole family can enjoy the benefits of Time Machine.
But if you look at the current Time Machine page on Apple’s Web site, that text is nowhere to be found.
That was a long time ago, it has never been officially implemented, and at present they specifically say it cannot be done.
In summary, it may work, but probably won't, and even if it does it may not be reliable.
