Syncing iPhone with more than one Mac

Up to now I've synced my iPhone with just one of my Macs, the main desktop machine that sits at home. However, when I'm away from home for more than a few days I miss the ability to sync podcasts, applications and do backups.
Is there a way of syncing the phone with a second (or third) Mac without having to have the full iTunes library on those computers? I would like to be able to backup the phone, sync apps and podcasts. Music and videos do not matter as long as the sync doesn't wipe existing copies from the phone. Incidentally, I use MobileMe for syncing calendars and contacts, so that isn't an issue. Any guidance would be appreciated.

I think that without the steps in that 'minefield' the iPhone will detect a change of Mac and even if all the content is on the other Mac, it will all have to be re-loaded onto the phone. Probably not a good idea to keep the library remotely, I expect. But, copying the whole library may work - if you have the time, it's worth a try. Just sync the iPhone to your desktop machine first so the backup is updated, then copy over the library to the portable, then try syncing there. If it works, great. If not, you can Restore the iPhone from the desktop if you need to.

Sync iPhone on more than one mac and deleting app

Hello everyone,i have two mac, a laptop and a desktop that are in two different places and not connected to the same network, I would like my Iphone it synced automatically with the itunes of both and that my content was present equally in all 3 equipment: music and app. How can I do?
A second problem concerns the app: when I delete an app from the iphone is not deleted directly from the itunes mac and I must go among all the app hope to remember which one it is and delete it manually, is there a way to do that once deleted from iphone is also automatically delete on the mac itunes?
Thanks in advance

You can't. By design, iPhone syncs or manually manages with one computer at a time. Each time you change computers, all iTunes content gets erased from your phone.

Sorry, no way to do that either.

Sync iPod/iPad/iPhone with two computers
Although it isn't possible to sync an Apple device with two different libraries it is possible to sync with the same logical library from multiple computers. Each library has an internal ID and when iTunes connects to your iPod/iPad/iPhone it compares the local ID with the one the device normally syncs with. If they are the same you can go ahead and sync...
I have my library cloned to a small 1Tb USB drive which I can take between home & work. At either location I use SyncToy 2.1 to update the local copy with the external drive. Mac users should be able to find similar tools. I can open either of the local libraries or the one on the external drive and update the media content of my iPhone. The slight exception is Photos which normally connects to a specific folder on a specific machine, although that can easily be remapped to the current library if you create a "Photos" folder inside the iTunes Media folder so that syncing the iTunes folders keeps this up to date as well. I periodically sweep my library for new files & orphans with iTunes Folder Watch just in case I make changes at one location but then overwrite the library with a newer copy from the other. Again Mac users should be able to find similar tools.
As long as your media is organised within an iTunes Music or Tunes Media folder, in turn held inside the main iTunes folder that has your library files (whether or not you let iTunes keep the media folder organised) each library can access items at the same relative path from the library folder so the library can be at different drives/paths on different machines. This solution ensures I always have adequate backups of my library and I can update my devices whenever I can connect to the same build of iTunes.
When working with an iPhone earlier builds of iTunes would remove any file not physically present in the local library, even if there was an entry for it, making manual management practically redundant on the iPhone. This behaviour has been changed but it will still only permit manual management with a library that has the correct internal ID. If you don't want to sync your library between machines on a regular basis just copy the iTunes Library.itl file from the current "home" machine to any other you want to use, then clean out the library entries and import the local content you have on that box.

Can I use a magic trackpad with more than one Mac at a time?

I am attempting to pair a MTP with a second MacBook Pro. So far I can't get system preferences to find the MTP.
I am wondering whether the MTP can be paired with only one Mac at a time, and that this is why my MBP won't find it.
The reason I am thinking this is because the little booklet that comes with the MTP says 'after you pair your MTP with a Mac, you can pair it again with a different Mac. To do this, you first remove the existing pairing and then pair the trackpad again'.
Can anyone advise, please?
If it can be paired with more than one MBP at a time, any suggestions why my system preferences search for the MTP is not producing any results?
Thanks

Yes, your keyboard, mouse or trackpad can be paired with multiple Macs. You can even have multiple keyboards, mice or trackpads paired with one Mac. The caveat is that the device can only be connected to one Mac at a time. The device can't be paired or connected with a Mac while it's currently connected to another.
Pairing a device with 2 Macs will be troublesome if the Macs are located within 33 ft of each other. The device will connect with the first available paired Mac and then unavailable to the second. If the Macs are located outside the 10meter range, it's quite easy to power off the keyboard (forcing a disconnect) then walking the keyboard to Mac 2 and powering the keyboard on. I do this with a keyboard from my iMac to a Mac Mini in another room.

Synching with more than one mac?

I want to synch my Touch with iCal and Address Book on more than one mac. Is there a way to do this? Can I somehow rename the iTunes on each mac the same name so it thinks all the macs are the same mac?
Thanks.

This is kind of annoying. Well, actually it is VERY annoying. I admit I don't quite understand this concept.
So if I go to my friend's house for a party and I want to play my tunes on his computer I, how does that work? I have to erase my iPod to be able to talk to his computer?
I know I could travel around with a cable with a mini plug at each end but sweet marie. My iPod Classic can speak to whichever computer I please.
If I had actually paid for my iPod I would take it back.
Am I over reacting?

Syncing iphone using more than one computer

Does anyone know how to get iphone to sync to more than one computer? I activated my wife's iphone from my computer (after having logged into her itunes account) but when I try to sync from her computer (logged into her account) nothing happens.

You can, but you can only sync one type of information with each computer. Here are the instructions I followed to sync my two computers. Hope they help.
How to Sync with Two Computers
You can sync your iPhone with only ONE media library. However, it is possible to sync the media library with one computer (like your home computer), and the contacts/calendar information with another computer (like your work computer). I have this working on two PCs with Windows XP. I have read posts of folks doing it with two Macs, and with one Mac and one PC.
This is not sanctioned by Apple, so I dont know if these steps are "correct". I only know that these are the steps I followed and worked for me. Your mileage may vary.
1. Select "Disable automatic syncing for all iPhones" under Edit / Preferences / iPhone in the iTunes menu.
2. Uncheck "Automatically sync when this iPhone is connected" in the Summary tab of iTunes.
3. Check "Only sync checked items" in the same tab.
4. On the computer you want to sync contacts and calendar, check the corresponding boxes in the Info tab. UNCHECK everything else in the MUSIC, PHOTOS, PODCASTS and VIDEO tabs.
5. Sync your iPhone with this computer FIRST.
6. On your other computer, follow the same steps above (1, 2 and 3). Then, UNCHECK everything in the INFO tab, and check everything else on the other tabs.
7. When you sync with this second computer, you may get a message that the iPhone has already been synced with another computer, and that the media library will be deleted. Fine. There should be NO media library on the iPhone since you unchecked all the media items on the first computer, right?
8. Sync. Then you can sync on both computers and each will sync what is checked and not overwrite the rest.

Can you sync Ipad with more than one computer?

I am just curious, can I associate my Ipad with more than 1 computer. I have a desktop and a laptop both with itunes and same library. Can I sync the Ipad on both computers without it totally erasing the Ipad or should I only sync it on one computer?
Than kyou in advance for the help.

In theory - If the libraries are identical, yes it should work. Keeping the libraries identical might become a little challenging. You may want to make sure that you always manually transfer purchases whenever you sync to each computer to make sure that all content is always being transferred into each iTunes library and I would think that you would want to backup each time you sync as well. And you might want to sync with the one computer right after you sync with the other computer so that all of your data remains intact in the backups of both computers.
You can always check by giving it a try and see of you get the "this iPad have been synced to a different computer" message and see what happens. If the message pops up, just cancel and don't sync.
However, I wouldn't recommend doing this unless you absolutely have to for some reason.

Can i sync my iphone with more than one itunes library without erasing content?

So i just got a replacement iphone yesterday, and restored from a backup all my contacts and stuff.
I dont have my own laptop so when it comes to music i get all of my mine from other computers...this has never been a problem with my phone or ipods, but i guess it is now...when i click on manually manage it says:
"An iPhone can be synced with only one iTunes library at a time. Erasing and syncing replaces the contents of this iPhone with the contents of this iTunes library."
so i cannot go to a second device and take songs from them without erasing the ones from the previous comp.
they used to be able to authorized on up to 5 comps right? is this a new strict setting, or is there a way around it??
thanks

No. An iPhone can be synced with only one iTunes library at a time. Erasing and syncing replaces the contents of this iPhone with the contents of this iTunes library.
Basically you'd want to get the music to the library first, then sync it to the phone after you get it set up in your library. iTunes will not transfer songs off the phone that were not purchased through the iTunes store, so they need to be in your library beforehand. You might consult with the googles if there are other third party ways to do that.
The 5 compy authorization is for iTunes account authorization, which means transfering music bought through itunes, apps, etc.

Syncing iPhoto '08 with more than one mac

I have recently got a macbook and would like to ensure that the photos I have on my iMac at home are the same as the photos I have on the macbook.
I have a .Mac account with some photos on their and would like them to appear in iPhoto on my macbook.
Is there a simple way to do this?

PHarris
No, there's no simple way to do this.
While it is perfectly possible to copy a library from one machine to another, syncing them - where you're trying to update each library with the other's contents - is not possible. No app can parse the library file, and so syncing them will cause corruption of one, other or both libraries.
Some possibilities: if you only import and organise on one Mac, then simply copy the iPhoto Library from the Pictures Folder on that Mac to the same location on the portable.
You can use iPhoto Library Manager to copy files/events/albums from one library to another. This is the only way to move files and metadata from one library to another.
I have a .Mac account with some photos on their and would like them to appear in iPhoto on my macbook.
Are these files simply loose on the .Mac account? Then import them.

How does syncing apps with more than one iPhones work?

Me and my girlfriend both has a iPhone. I was wondering do I have to purchase the app twice for both iPhones?are apps tied with my computer, the phone or my iTunes account? Assuming I purchase it from my mac there's no way to say which iPhone it is for so I assume I can use of on both phone? But what of I bought it from the phone?

Yes you can do this. It works just like music, you do not have to purchase an app twice if, for example, you purchase an app and then would like to also put it onto your husband or wife's iPhone. You can authorize up to five computers to "hold onto" the app and allow it to be synchronized down to the iPhone. I did this with two computers, mine and my wife's, synching to two iPhones, mine and hers. There's probably a limit of 5 iPhones too, but I don't know for sure.
You can simply email an app, or put it onto a CD or external storage device to move it to another computer, and then authorize it on the additional computer.
Here's what you need to know:
Go to iTunes on a computer that has the app. Top left, Library menu, click on Applications to display the applications which are on this computer. You'll get a big screen that says IPhone and IPod Touch Apps, and icons for each. Right click (Control-click if you have to) to get the contextual menu, and select "Show in Finder." All of your apps should be residing in the resulting folder. Grab one or more of them and email or copy to a CD or external drive (or transfer by network) to get the app onto the additional computer. On my computer this is the "Mobile Applications" folder in my iTunes Library; this appears to be the default location. Of course you need to put the app into the correct default folder on the new computer.
Once the app(s) is on the new computer, it may not show up in iTunes (look in the same place; in other words, open iTunes, go to "Library --> Applications" top left). If it's not showing up in iTunes, then simply go back to the folder (the actual app in the finder) and right-click and select Open With --> iTunes. That'll force it to show up. Your goal is for the app to show up in iTunes on the "new" (additional) computer. Once it shows up, you are almost there, although it is not yet authorized, so if you go ahead and sync with your iPhone on this additional computer the transfer will fail.
To authorize it, simply double click on the app IN iTUNES, right there in the Library -->Applications view. A window will pop up and say you are not authorized to play this (just like it does when you try to play a song you originally purchased on a different computer). The user name that is displayed will be the user name of the original purchaser. Enter the password of the original purchaser. You are good to go. If you added multiple apps, they will all become authorized on this additional computer with this single authorization action, you do not have to repeat the authorization for each of them, as long as they all were purchased by the same user.
Proceed with syncing the additional iPhone using iTunes on the additonal computer. You are done. Enjoy!
This will work with no regard to AT+T accounts, it's not related to them at all. You can have five authorized computers, including the one which originally purchased the song or app. You can send an app to a friend who lives in a faraway place and allow him to authorize his computer to play your apps and songs. Note that he will be able to play all of your apps and songs forever until you deauthorize his computer. This does not mean he will have access to your account in any way; simply that he will have general authorization for any songs or apps you send him; he won't need to re-authorize any new things you send him. In order to allow you to maintain control (change your mind) there is an option in the iTunes Store (Account button) which allows you to deauthorize ALL computers on your account, if you wish to reauthorize individual computers again.
The apps and songs are simply password protected. If you send one to someone they won't be able to use it unless they know your password, and you can allow this up to five times (for five computers).
