Synchronizing files on multiple computers with 1 usb stick

i would like to synchroze a number of different files and folders on 2 or more machines with a usb stick. each folder exists normally only on 1 machine and the usb stick, so the stick should synchronize different folders when connected to different machines.
as an example; on computer 1 i have files a, b & c of which i would like to have a current backup version on the usb. on computer 2 i have files d and e.
so on the stick i have files a, b, c, d and e.
every time when the stick is used with computer 2, i want to synchronize files d and e only. every time when the stick is used with computer 1, it should synchronize files a, b and c only.
instead of installing just any synchronization software on every machine that i would use, i would prefer to have the program installed only on the usb stick and run it from there.
theoretically it whould then find its settings in ~/Library/Preferences where it will find settings specific for that machine (whether to synchronize files a, b and c or files d and e)
all machines i'd be using for this run various versions of os 10, but all 10.3.9 or later
so far theory - is there anyone who's done this? with how many machines? any experiences? things to do or to avoid?
thanks

No problem. Post back with any questions. We'll see what we can come up with...
Playlists can be exported and imported between iTunes setups. Not sure you can truly 'merge' the embedded meta-data in the IL file. Only what is stored within the song file itself.

How to synchronize multiple computers via usb stick?

I have three computers on which I work most of the time and I have some files, that I have to access/change on all three and thus I have to sync these files. I would like to do this using an usb stick. To do so, I formatted a partition on my usb stick as ext4 (without journaling) and then use unison to synchronize the files from one computer to the usb stick when I'm done working on one computer and before I start, I do the same.
Unfortunately, I have different uid and gid on the different computers (and I cannot change that as I'm not admin on every one). Unison can still take readable files from the usb stick and store them with my `correct' local uid, but unfortunately it cannot create new files/folders on the usb stick, as the folders are often with rwxr-xr-x permission.
There are some suggestions, such as here to simply change the ownership of all files recursively, but since I'm not root, I cannot do that. (Additionally this solution does not feel optimal, as I would have to change the permission bits with every mount -- and this is probably not the best to do to an usb stick(?).)
So after the whole lament my actual questions:
o Is there a file system, that can store permissions (such as redable/writable with user and group support), but that I can mount with changed permissions (e.g. translate uid=1023 to uid=17011 while mounting but leavin the actual bits set) and that is suitable for use with an usb stick?
o Is there a tool to mount/remount the usb stick with `translated' permissions?
o Is there any other solution you could think of to accomplish my syncing? (Keep in mind, that sky/cloud drives are no possibilities, as not all of my computers have internet access.)
Note: The permissions (which file is rwx and which is only r--) is actually something I want to preserve during this sync-process -- that's why I used ext4 in the first place.

I don't want to change the permissions stored on the usb stick. I just want identical files on all my three systems (also with the permissions set correctly), but I want to use my local uid instead of the uid stored on the stick. So that the mounting system does not see ``uid=1023 has rwx for file /mnt/foo'', as it's stored on the usb stick, but I want it to see ``uid=17011 has rwx for file /mnt/foo''.
I Imagine some tool like a table that links the actual, stored, uid on the stick (1023) to the one, I want my system to perceive (17011).
If I make a file executable, I want to keep that information. If I store that file on a fat, it's lost.

ARD won't save multiple computers with same IP and different port!

I'm trying to access multiple computers over the internet behind a firewall with port forwarding.
I can access each computer, but ARD won't save the IP address and port (in IP Address column of ARD 3.1) of multiple computers with the same IP address. It will only save ONE. I've tried 'add by address', adding a list for each computer or adding a list for all those computers. Nothing has worked. ARD will actually change the first computer's IP address to 0.0.0.0
Example: Static IP address
Computer 1 xx.xxx.xxx.xxx:51 (public port 51 is forwarded to port 5900 on computer 1)
Computer 2 xx.xxx.xxx.xxx:52 (public port 52 is forwarded to port 5900 on computer 2)
Computer 3 xx.xxx.xxx.xxx:53 (public port 53 is forwarded to port 5900 on computer 3)
Has Apple really overlooked this or am I missing something? Isn't this how most people would remotely manage multiple Macs offsite?
Thanks

ARD cannot do this as you're asking. If your
workstations get their addresses from an NAT device
rather than being "real", the ports also need to be
forwarded in the router to the workstation's internal
IP address. ARD uses port 3283 for the reporting and
updating function, so if your Macs are getting their
IP addresses through NAT, since you can only forward
a port to a single workstation, you can only get
reports, push package/files to etc. for a single
workstation.
ARD uses the VNC protocol for observation and
control, though, and there are a range of IP
addresses for that protocol, starting with 5900. ARD
uses 5900 by default, so that port would be forwarded
to the first workstation. You would, I believe, need
to install VNC servers on the systems (since the ARD
client cannot listen on any port other than 5900
while VNC servers can be set for other ports such as
5901, 5902, etc. You would then forward 5901 to the
second workstation (and on to 5902, 5903, etc.). You
can then use the following information:
Remote Desktop 2: How to specify a port number
for a VNC client
to connect.
The only other options are: 1) to run the ARD
administrator on a workstation on the network, and
then take control of that system from outside, either
via VNC or another copy of ARD, or 2) set up a
virtual private network (VPN) so that when you
connect from outside, your admin system is officially
part of the local network.
Hope this helps.
That definitely helps. I have ARD installed on my MBP and on a workstation on the LAN. I have used ARD from the MBP to control ARD on a workstation on the local network, but it can get a little tricky. I already have VNC setup on all the workstations. I used to use COTVNC prior to purchasing ARD 3.1.
I guess what I'm really asking is...
How do I add a list of workstations and save the settings (same IP address for each workstation with different ports?) to control/VNC via ARD?
I simply want a list that shows each workstation, so I can control/VNC them using ARD offsite.
Name: Computer 1 IP Address: 123.123.123.123:5901
Name: Computer 2 IP Address: 123.123.123.123:5902
Name: Computer 3 IP Address: 123.123.123.123:5903
I don't want to have to manually type in the IP address into ARD every time.
Will ARD simply not add another computer to the list if it has the same IP address but different port number as a computer already on the list? I haven't been able to find a way to make ARD do this.

Is it possible to use Adobe Illustrator in multiple computers with the same account?

Hi guys,
So our company is a small designing tile company,
we wanted to purchase the Adobe Illustrator and was wondering if it was possible to use it in multiple computers with one account, as we have two computers that are frequently use for designing, or do we have to buy two separated Adobes Illustrators for each computer?
Thanks

ITunes on multiple computers with shared external library?

Hey guys. I thought I might pick everyone's brain here. I just purchased a MacBook Air with just 128GB SSD but that should be fine as far as local storage. I have an iTunes library that is over 350GB and it grows everyday so even the 256GB storage wouldn't have been enough for me. I have multiple computers and also have an iPod, iPad and iPhone. They all sync via my MacBook through an external hard drive right now and this is the only computer I currently sync to.
Since I have a Mac Mini as well as a iMac, I want to see if there is a way that I can wirelessly share the external hard drive with the itunes library in it and all the computers would be hooked up to it going off that one source and itunes library. I buy music from not only itunes so I import music all the time to itunes and also want to make sure that it will update to the computers that are connected to the library automatically as I wouldn't want any inconsistency's when I need to sync one of my devices to one of my computers.
I hope there is a way to do this, and if there is can you please help me out and explain or point me in the right direction at least to where I can find out about this?
It would be much appreciated. Thank you!

Just a thought. Should I somehow open iTunes on MBP2 using MBP1's Library file??
both Macs can access the same library file, however, only one at a time !
to do that, you would ideally have the entire iTunes folder (not just the iTunes music folder) on the external. then, on one Mac after the other, launch iTunes while holding the option key, click on +choose library+ when prompted, and select the iTunes folder on the external.
or, you could have two separate libraries and keep those in sync using third party tools such as Syncopation, TuneRanger or SuperSync.
for purchases from the iTunes store, you could set up _*Home Sharing*_ - it can be configured to automatically transfer new purchases to home shared libraries.
Can I create a script to have MBP1 always save the iTunes Library file on the shared hard drive?
no need.

Resource fork et al deletion with usb stick drives

I know there are lots of discussions about 'extra files' not used by other operating systems (such as resource forks and .Trashes and .DS_Stores and spotlight files and and whatever) so I hope this doesn't bore people but....
I use a usb stick a lot, mostly to share data cross-platform. I want to get rid of the unusable files to make my colleagues' life easier and unclog my life. I know I prevent some of them over network connections, but that is only some of them, and that is only over network connections.
I can't disable the creation of these using the method that applies to network connections (Article: HT1629).
Can I just go to terminal and go:
cd /Volumes/USBStick
rm -fr .*
This is seeming to work. I get an error about not being able to delete the . file and the .. file, but it happily goes ahead and gets rid of the rest.
Seeing that it appears to work, can I dispense with paying for BlueHarvest (at least for my situation)? Or have I inadvertently destroyed essential data and should expect imminent falling of the sky upon my head?
thanks all,
diddles.

Definitely a yawn here. As your wonderful machine is the source of this important data that's transferred over to that 'other' platform, convince your colleague that his life will be easier still if he buys a Mac. Thereafter, the invisible files will be just that.
An expensive solution, but I think a good one.

Install an app on multiple computers with the Creative Cloud membership?

I have the Creative Cloud membership. Can I install an app on multiple computers? I wouldn't use the app on different computers at the same time.

You can install on as many machines as you like, but the account can only ever be active on 2 machines at any given time. If you need to move to anotehr machine, you need to sign out with a full deactivation on one of the two machines in use.

Multiple computers with iPod

Hello, I'm new to the forum, hope you folks can holp out. I am planning to purchase a new iPod video. I want to sync it with tunes and photos here at home on my iMac. In a few months I will be going overseas for at least a year and will be getting a laptop once I am there, not sure yet but most likely a pc. I will then want to load things from that new pc to my iPod, adding them to what will be there from my iMac. Can this be accomplished and how? Thanks!

Using iPod with Multiple Computers.
Since you're using two different operating systems, it would be best if you formatted the iPod for Windows, since that would allow it to be used on both a PC and a Mac.

Think M72e start windows 7 with usb stick inserted

I know in the scheme of things my M72e annoyance is pretty minor,but I am more curious than exasperated.
If I try to start the machine with a usb stick in any of the ports it won't boot into windows 7and I get a "No bootable partition in table" message and the machine just hangs there.
If I remove the usb stick and restart, it boots to windows 7 fine.
Obviously, i figured that the machine is trying to boot off the usb stick before the harddrive. So I went into the bios but there is no option to boot off the hardrive first.
I can press F12 and it gives me a one time option to boot off the hardrive but I don't want to have to do this everytime.
Anybody know why Lenovo in its wisdom hobbled the boot choices in the bios?
Thanks,

Strange behavior with USB stick

I was using gnome-disk-utility in order to format a USB stick when I mistakenly clicked on the button which puts the stick offline.
Since then, it refuses to mount on USB 3.0 ports on my computer, but works perfectly well on USB 2.0 ports...
I have got another stick which is the same model, and it works great on USB 3.0 ports. This is really weird...
I tried to re-format it completely, but it does nothing.
Also on "demsg" I notice that usb does a loop, saying:

And so on...
Does anyone have a suggestion?
Any idea what's going on?
Thanks in advance.

Is the bug present also in kernel 3.10 lts ?
Because it doesn't work with it either... Maybe it's related to the stick itself.
I think I'm going to send it back.

IOS4.2 kills Camera Kit operation in combination with USB-Sticks and more

Hi guys,
When I decided to go for an iPad, one of the main reasons why not to stay with Microsoft was the connectivity in combination with cameras and USB-sticks.
Well then, the update to iOS4.2 killed this because the software seems to lower the max.current limit from 200mA down to some 20mA. This "unfriendly" action by Apple is in my opinion fraud. I bought a lot of accessories to work with the iPod and all of them I can now dump into the trash cane, because Apple is doing the same ignorant "politics" to consumer just like their biggest rival Microsoft.
This is company arrogance in excellence....
...never again an Apple product, that was is, over

I'm experiencing the same problem and Apple is jacking me around. A great product but behind the phone are no customer service.
Bring back the true IPAD and apple fix the problem.
Apple can read the Dissuasions and do something about it.
Unhappy customer too

Odd free space issue with USB stick

I'm wondering what may be the cause of this. I have a 2 GB USB stick that 10.6.3 tells me has 2.02 GB available, yet I get an insufficient space error when attempting to move a 831 KB file to the stick. Could there be hidden files mucking up how the OS reads the stick?

I couldn't guess the cause but why don't you try reformatting the stick?

Can time machine backup multiple computers with encryption?

I want to use the encryption option with Time Machine, using a single portable drive between multiple computers. Will this work; does it encrypt the entire drive, or each individual backup? If it does encrypt the entire drive, can the other computers make use of it?

Although the documentation says you can copy Time Machine backups in the Finder, it sometimes doesn't work.
Launch Disk Utility, open the built-in help, and search for the term "Duplicate." Follow the instructions.

Talking amongst multiple computers with only one .mac acct

We have multiple computers but only one .mac account. We would like to isight/ichat with our home-based computers from our laptops (ie: talk with the kids at home while we're on the road...) but can't figure out how to make it work. Do we need to set up SEPARATE .mac accounts ("Family Plan") in order to isight/ichat amongst our computers or can we arrange it all, using only one account?

Magpie is right.
You can get FREE AIM Name(s) here.
You can also get additional free dot mac names if you like. The names will continue to work as iChat names after the free trial (and other dot mac features) expire.

Multiple computers with iPhone 3GS

Everyone,
perhaps someone can answer this question for me. I have two main computers I use with my new iPhone: one at work and one at home - each computer (Windows XP) with its own library. I used to manually manage an iPod mini between these two computers with no problems. I could add/delete songs to the iPod from each of the libraries. With the new iPhone I noticed a different behavior, although I am manually managing the music. Everything is fine with the work computer. But with the home computer, all my songs on the iPhone are grayed out and cannot be modified. iTunes is asking me to sync with the new library, which I don't want to do since it will erase the content of my iPhone. Is this normal behavior, even for a manually managed iPhone? If it is, is there a workaround to be able to use the iPhone on both computers without having to delete contents while doing so?
Thanks for any advice,
Toni

The iPhone does not support disk mode as is supported with an iPod, which is required for this even with manually manage music and videos selected for the iPhone's sync preferences.
In regards to iTunes content, an iPhone can be synced or manually managed with an iTunes library on a single computer only, and photos can be transferred from a single computer only.
