Duplicate Email Alarms When Syncing Multiple Computers

I have iCal set up on multiple computers, a desktop and a PowerBook. Both are syncing via .mac, which is ideal because I can add an event on either computer and it updates both.
This however causes a problem. Email alarms from both computers end up sending me the same reminder. Resulting in my inbox receiving the same alert several times.
How can I stop email alarms from but one computer?
What adjustments do I need to make?
Regards,
Ed

Good for you.

When syncing multiple Google calendars to iPad, switching event to different calendar on iPad creates a duplicate in Google. Ideas?

When syncing multiple Google calendars to iPad, switching event to different Google sub-calendar using iPad creates a duplicate in Google.
Using Google account with the Exchange setup on an iPad mini. iOS up to date. I have a secondary calendar in my Google account for some appointments, and when I create the event on the iPad and it defaults to my main Google calendar, changing the event to the secondary calendar caused the following:
1) at first, the event totally disappeared from my iPad. Scary! Reappeared when I went into Gcal on the web, opened the event to edit, and re-saved. Phew.
2) Failing to re-create error #1, I switched a new event from primary to secondary calendar, and it then appears correct on iPad, but is duplicated on the web. The duplicate remains even after deleting the changed event on iPad, refreshing Gcal, etc.
Just curious if anyone else is having this problem or has discovered a workaround or fix.

When you open the Calendar app, tap the button at the top-left corner (Calendars). That should reveal all the calendars you have available, and you can select/ un-select any or all of them.
If you don't see your 2nd GMail calendar listed, go into Settings/ Mail/ (account name) and make sure you've turned the calendar ON for this account.

Sync multiple computers?

Is there any way to sync multiple computers at the same time? Let's say my eMac is used as my main computer...but I also want all my music on my MacBook (which I have not bought yet but will soon)....is there a away to do this at the same time as i Sync the music to the iPod? Or would I have to connect the 2 macs together and do the addition manually? Or is there a way to do it over an airport network?

I do something similar to what you want to do. I used a wired LAN to connect three computers. iTunes on each computer points to the same location for the library, an external hard drive connected to my "main" computer. When I add an album or song I do it on the main computer and then I have to go to each computer and use Add To Library and point to the file(s) created by the main iTunes.
There is also Playlist Sharing, but you can only play songs, not organize them, on any computer but the sharing computer. Any computer can see and play all playists that are shared from any computer.

Duplicate email alarms sent when syncing iCal on multiple computers

Hi, I have iCal set up on my laptop, my work computer and my home computer and they all are syncing using .mac, which is great because I can add an event on any computer and it updates everywhere. The problem is that when I have an event that has an email alarm all three computers end up sending me a reminder. As a result my inbox looks like a plate of spam. Is there a way I can suppress email alarms from all but one of the computers?
Thanks in advance.

I sync my iPhone with two different computers. This appears to be something new & unique for the iPhone.
My "Info" data (contacts, bookmarks, calendar, mail) comes from my iBook. My "Media" data (music, podcasts, video) comes from my desktop PC.
I don't believe you can mix the sync data beyond that. In other words, you can't sync podcasts from one computer and music from a second.
When I started doing this, I recall getting prompted to erase all data before continuing the sync in the traditional iPod method of 1 computer to 1 iPod. But hitting Cancel to that question actually continued the sync without deleting the iPhone resident non-synced data. You may have to do that on both systems (the Cancel), but now it seems automatic. The iBook just touches the Info data & the PC just touches the media data.
I also turned off 'auto-sync' in both iTunes for the iPhone. I'm not sure if that made a difference for the dual sync. I just prefer to kick off the sync manually in case I'm downloading new podcasts or just need to charge the iPhone and don't want to go through a sync at that moment.

ICal will not sync multiple computers

Wow, this has taken a lot of my time today. Mighty unfortunate too. I was extremely busy at work, I have a busy job and my hands in a lot of places. As you can imagine, I live and die by iCal (although I'm liking Things a lot better lately). So I was pretty shocked when I realized that iCal syncing with my iPhone was behaving very strangely - and it took me a while to figure this out but I've since proved it on multiple machines running similar software - MERGE INFO IS ACTING LIKE REPLACE INFO. Since I had some calendar info on one computer, some on another I had to painstakingly go thru each day and match the data. NOT FUN. So I got iCal finally set manually on one computer.
Now before I continue, let me note that both computers are running iTunes 9.2 and 10.6.4, matching data. iPhone is running latest iOS4.0.1. This should work. I have been using this method successfully for two years. I don't really like the merge info option, I wish there was a general SYNC, but that's another story. So I was shocked when I upgraded to iPhone 3GS / iOS4.0.1 (both happened the same day) and my calendar is screwed up beyond belief and won't sync. I'd previously been running iPhone 3G / iOS3.1.1 quite successfully in this manner.
So I got everything manually set on my MBP, and synced my phone. Merged info. Worked.. all info synced over to iphone - Yay! So then I needed to get this info over to my work computer, an iMac, same specs pretty much as my MBP. So I tried the usual merge info... it REPLACED the info on my iMac.
read that? MERGE INFO IS REPLACING INFO ON MULTIPLE MACHINES.
At first I thought something was wrong with my iMac. I went thru forums and tried suggestions, removing preferences, cache, etc. Didn't work.
So I tried the same thing on another machine... Mac Pro at home. It did the same thing as the iMac... hitting Merge info Replaced all my calendar info. Thankfully, my laptop isn't pulling this maneuver.
Why is this happening, what can be done?

Why is this happening, what can be done?
Why: You have a damaged calendar database or corrupt data in SyncServices (the database that handles syncing) on one or more of your devices or on MobileMe. I assume you are syncing using MobileMe?
What: Replace all the calendar data on all devices with one good working copy.
A good read before proceeding is this article on advanced sync troubleshooting: http://support.apple.com/kb/TS2481
How (Read all the way through before attempting. Make backups of all computers before attempting):
__Make one iCal on one computer 100% correct the way you want it to look. This will be your Master calendar.
__Make a backup of this good calendar by clicking on each calendar on the left and going to File > Export > Export, making an ICS file for each calendar. Reserve these incase things go wrong.
__Go to each computer and set syncing to Manually: Apple > System Preferences > MobileMe > Sync > Manually
__Go to each iPhone being synced and delete the MobileMe account being used from Settings > Mai / Contacts / Calendars > Accounts -- Remove the calendar data if prompted.
__On the computer with the Master calendar go to Apple > System Preferences > MobileMe > Sync > Advanced
__Click on each computer in the list at the top of the window and choose "Unregister". Continue this until the window is blank.
__Click done.
__When prompted, delete your unused sync data > Calendars
__Login to me.com and ensure that the Calendars are indeed blank. This can take up to 15 minutes to refresh.
__Once MobileMe shows blank for calendars, on the computer with the Master calendar go to Apple > System Preferences > MobileMe > Sync and turning syncing on for Calendars and set to Sync manually
__Follow this article to reset sync services on all computers affected: http://support.apple.com/kb/TS1627
__On the computer with the Master calendar Go to Apple > System Preferences > MobileMe > Sync > Advanced and click on Reset Sync Data.
__Make the reset go from this computer to the MobileMe cloud.
__Replace the data on MobileMe with the Master data on the computer
__Login to me.com and check to make sure the Calendar now appears online and looks the way it should. This can take up to 15 minutes to appear.
__Once the calendar online shows the correct data, go to each computer being synced and go to go to Apple > System Preferences > MobileMe > Sync > Advanced and Reset Sync data from MobileMe down to the Mac. This will bring the Master calendar down to these computers.
__Re-add the MobileMe account to your iPhone so it too will bring down the Master Calendar.
Hope that helps.

Duplicate Email Forms When Dragging PDF

Don't know if this happens to other computers, but I can repeat it at will on mine....
Create a document and save it as a PDF onto your desktop. Close all windows, then drag the PDF onto the Mail icon in the Dock to create a new email message with the PDF attached to it.
On my system, with several different PDF files, when I do this, I get an email form with the PDF attached to it...and another blank email form just behind it with no attachment.
For some reason, dragging the PDF onto the Mail icon in the Dock creates 2 mail forms.
Anybody else seeing this?

unfortunately it DOES happen to others... there is another longer thread here about the problem. no solution found yet.

Problems with email addresses when syncing with MS-Exchange

When I sync with MS-Exchange, everything is great except for the email address. I get IMCEAEX-o=BlahMail_ou=BlahUS_cn=Recipientscn=[email protected] I tried to play with the email address in exchange, but it is always doing some auto-lookup to the person and never taking just the text.
Thanks for any help.

It seems the imceaex is Exchanges "IMC Encapsulated Address Exchange". Something for simulating X.500.
Anyone have any idea?

When syncing multiple iPhones iTunes resets configured contacts

We have 3 iPhones (2 3GS, 1 3G) that sync with iTunes on one computer using the same iTunes account. Every once in a while, after one iPhone syncs the next iPhone to sync gets the contacts from the first iPhone. So my wife and daughter both sync contacts with separate Yahoo address books. When my daughter synced her iPhone last night, iTunes synced with my wife's address book. My daughter lost all of her contacts. We got them all restored from the backup so we were able to recover. When we later looked at the contacts configuration, iTunes was using my wife's address book with my daughter's iPhone. Is this a bug in iTunes?

Your best option is to set up multiple user accounts, one for each member of the family, and enable Fast User Switching to avoid this.
The iPhone will sync with only one Address Book hence the reason you keep overwriting each others' data.

(r)sync multiple computers, howto delete files?

Hi All,
I would like to use rsync to sync my home directory across multiple machines. When I invoke rsync like this, I get the new and modified files from the server
rsync 192.168.x.y:/home /home
Then with a second rsync command, I push my new and modified files to the server:
rsync /home 192.168.x.y:/home
This works perfectly when I'm only adding and modifying files, but when I remove a file from my PC, and then sync with the server, the file is restored. I don't know a way to delete a file without the other workstation restoring it.
I can also invoke rync with the --delete flag. But this does not work well when I sync from a second PC with the server, the 2 workstations will then delete the new files the other machine has made on the server.
So my question is: How can I remove a file from a set of sync'd machines? I have heard about clustered filesystems, but I think this is a bit overkill for the 4 PC's that I and my wife use :-)
Suggestions are much appreciated.
Regards,
Cedric

Maybe having /home on the server so you can mount and access it from any of the PCs would be easier?
Keeping stuff on the server is indeed more easy, but for me, it has a few drawbacks:
1) The data is further away, On my desktop I now have my data on a fast ssd, accessing it over the network will be a bit slower. The situation is worse on my laptop, it's wlan is only 1.5MB/s. But this is not a big problem, as the data will be cached in RAM on the clients.
2) The server has to be always powered. When my server is not powered, I cannot access my data. I do not like the idea to keep a server running when it's not used, eg. when all the clients are off. Ideally, the server would only run when one or more of the clients are online. I can imagine this can be done by letting the server ping the clients periodically, and then power-down when nobody replys, and let the clients send wake on lan packets when they want the server back. But then the user has to wait until the server is back online before he can access his data.
3) There always has to be an internet connection between the server and the clients. When I take my laptop to a place where I don't have internet, then it would still be nice to be able to show somebody pictures, or listen to some music.
Best regards,
Cedric

How can I keep one of my audio tracks stationary when syncing multiple tracks?

I am trying to edit a video that has external audio from an H4N recorder and internal audio from 2 Canon DSLRs. The internal audio is just there to help my sync everything and will be muted during output. From the H4N I have one long, continuous recording, but from the cameras I have shorter clips, not all of which happened exactly after the previous one.
Here's the issue I'm having: when I sync the two video clips & the external audio early in the timeline, everything lines up (using the automatic synchronization based on waveform). However, when I am syncing clips later in the timeline, sometimes Premiere chooses to pull the external audio track FORWARD (thus bringing it out of alignment with the earlier video), rather than pushing the video tracks BACK (which is what I need).
Is there some way to tell Premiere which tracks should and should not be moved during sync? If I lock the track, then I cannot use the sync function on it at all. I basically need a way to specify that one track should be used as the "anchor" and that others should be moved forward or backward as needed, without moving the "anchor" track.

Cut up the 4n audio clip and synch it to its respective clips.

Sync multiple computers with the same mailbox

Hello all,
I am using a Bold and syncing with MS Outlook 2007. I have it on both a desktop and my laptop (laptop being the first computer I used). I have tried to sync but am having issues with the calendar as I am getting multiple items, some items are being deleted randomly and others aren't syncing.
Any suggestions please? I have tried changing the default device and that made it worse!
Matt

what Niel said is correct.
however, there might be a (semi) workaround. check this thread for pointers: http://discussions.apple.com/message.jspa?messageID=11524444#11524444.

Podcast play count reset when syncing multiple devices

I have noticed some odd behavior since upgrading iTunes to version 10. My wife and I each have an iPhone, iPad, and an iPod nano. I have several playlists that I sync to each of my devices. The problem comes when I play some podcasts on one device, and other podcasts on another device. I sync one device, the play count updates. I sync one of the other devices, and the play count updates on some songs, but is deleted on others. I can tell which tracks have been reset because they still have a Last Played Date. It appears that the device with the most advanced time overwrites the play count in the library.
Anyone have any ideas on how to fix this behavior?
Doc

After much faffing, I have finally found out what to do. I've been stupid. Or maybe the whole sync thing isn't clear or intuitive, but probably I've been stupid.
I'm posting this because I couldn't find a definitive answer anywhere and because lots of people had similar questions to me.
The following settings work as I would expect them to. That is:
1. I have all my iTunes content on my iPod touch (not just some tracks, but all 8186 of them)
2. When I rate a track on the iPod, I expect that rating to copy into iTunes when I sync
3. I don't expect all 8186 songs to be wiped from my iPod and replaced again every time I sync; i.e. I only want any new ratings/artwork/tracks in iTunes to be duplicated on my iPod
So, here are my settings which work for me, at least:
1. In *iTunes Preferences*, on the Devices tab, *Prevent iPods and iPhones from syncing automatically* is unchecked
2. When the iPod is connected to my Mac, when clicking the iPod in the sidebar;
a) on the Summary tab, *Open iTunes when this iPod is attached* is unchecked
(I'm not sure if this makes a difference, but I usually already have iTunes open when connecting the iPod)
b) on the Music tab, *Sync Music:* and *Entire music library* are checked
3. I then click Sync at the bottom of that tab and, lo and behold, everything syncs properly.
Prior to this, I did have to go through that tedious process of having everything removed from the iPod and replaced, but it seems that that was a one-off chore and now things seem OK.
If you're syncing Apps, Calendar, Contacts, etc. too, then those settings can be checked in the Applications and Info tabs and that seems to function properly as well.
This may seem basic and obvious to some, but there does appear to be a lot of confused folks out there!

Send eMail via Thunderbird with filled "Email information" when using multiple profiles

Hello.
I hope you can help me.
We are using two Thunderbird profiles:
"Sales" and "Purchases".
We have thunderbird links for both of them on the desktop:
This is how we call start the firefox profiles:
Purchases: "C:\Program Files (x86)\Mozilla Thunderbird\thunderbird.exe" -no-remote -p Purchases
Sales: "C:\Program Files (x86)\Mozilla Thunderbird\thunderbird.exe" -no-remote -p Sales
(-no-remote is needed to start Thunderbird with two instances at once, -p <Profile> is to choose the profile)
Everything works so far.
Now we have an application which calls the "write"-dialog of thunderbird. (the dialog where you can send eMails)
When calling the "write"-dialog, the fields of this dialog (from, to, subject, and the text body) should be filled by parameters.
The application uses following call:
thunderbird.exe -compose to=[email protected],subject="example subject line",body="this is the example body" -no-remote -p Sales
That means that the send dialog of the Sales-Profile-Thunderbird should be opened with the "sales" profile.
(email receiver is filled with "[email protected]", subject is "example subject line", and the text is "this is the example body")
The Problem:
This works only if thunderbird with the "Sales" profile is not already running. If Thunderbird with the "Sales" profile is already running, Thunderbird is telling that the process is already running and should be closed first.
Before adding the second profile "Purchases", we only used "Sales" profile, and we started thunderbird without "-no-remote -p Sales".
With only one profile and without "-no-remote -p Sales", every worked well.
But with 2 profiles, the user always have to close thunderbird first before calling the "write"-dialog from our application.
Is there something I can do? Maybe changing the call used by our application to show the write-dialog?
If you need more information, or something is not clear enough, let me know.
Best regards
M. Jaeger

command line arguments here https://developer.mozilla.org/en-US/docs/Mozilla/Command_Line_Options
Perhaps the issue here is your desire for a separate profile for sales and purchases. That looks to me to be where the rot starts. Now your trying to start a third instance.
So how about you explain what it is your trying to achieve, as you can not be the only person in the world wanting to use email in a business.
I see a reference to a write dialog from your application. Is it your writing an application and trying to make Thunderbird work the way you have designed your application and it simply does not do that?

Sync Multiple computers to aTV

Ok...let me get this right (I hope I'm not right so PLEASE correct me if I'm wrong)...........
1) We can only sync one computer to the aTV but we can stream up to 5... My husband has a PB and I have an iMac and different movies on both. In order to get them sync'd to the aTV we have to move them to one computer first??
2) Even though your aTV may be sync'd with your computer, DON'T erase them from your HD and/or iTunes because they'll be erased from aTV as well.
That being said, here's my delemma: My SuperDrive has officially died in my "lampstand" airport-cardless iMac and I have 3 seasons of LOST and 6 movies. I only have 3GB left on my HD without any way of backing them up to DVD. ANY solutions would be wonderful

couldn't you just attach your iMac to your router via ethernet... then create a sharing folder (or add the iTunes folder as a sharing folder..) (http://docs.info.apple.com/article.html?path=Mac/10.5/en/17131.html) and then access the files on the iMac from the PowerBook? PowerBook can be attached via ethernet or wirelessly to the router.

Syncing itunes on multiple computers / devices

Not really a question, more like a suggestion for itunes developers.
I have iTunes on PC and iMac computers, and use an iPhone and iPad. I would like to have one itunes library that all the computers and devices see. This doesn't seem to be possible because the itunes lib is computer-specific == that is, the itunes on my PC is not aware of the itunes on my iMac (and don't get me started on AppleTV!!)
Now perhaps this is a DRM issue, and music publishers won't allow the sharing. Maybe. It's just frustrating that I can't modify a playlist or whatever and have it show up everywhere, regardless of where the change was made. Perhaps the answer is to lose the iMac and only do itunes on PCs? Would syncing multiple computers work if they were all PCs?
Apple has a reputation that everything just works. Sadly that doesn't seem to be as universal as it may once have been, but then it was just a reputation after all. If there's a way to make this just work that I haven't figured out yet, I'm eager to learn it. Bottom line is, I would like to have an iTunes library that can be displayed on any device I want, that can be modified from any device, and will appear the same on any device. Is such a thing possible?
Thanks for letting me vent.

Hello,
You can share your iTunes library between machines and devices when connected to your local network. Additionally, iTunes Match is a service which allows you to store your Music "in the cloud" and access it remotely.
