    Hi There,


    I don't appear to have the Library/Application Support/Address Book directory.  Should I have? I've tried everything else detailed on this topic, but the **** thing keeps coming back and reducing my MBP to a 10 year old Windows '95 machine!!


    Please Help!

    I believe you may be looking in the wrong "Library". You need to look in your User Library not the one listed if you just select you Mac HD. From the finder menu bar hold down the "Option" key and select "Go". You should see "Library" appear. Select it. From there select /Application Support and now you should see /Address Book.

    Any other options to fix this? I don't actually use iCloud to sync my address book, and I don't want to. Even logged out of iCloud and MobileMe, AddressBookSourceSync continues to rear its ugly head.

    Hi Nate and all. Thanks for all the info it was the same problem I was having + the slowing down. Thank god I found this link, however Library is not listed where you mentioned. Don't know why. Checked all library folders and none contains the info and also could not find any folder like the ones referred. I have a mid 2010 MBP. Any ideas? Thanks !

    Hi Guys, found the answer to my question https://discussions.apple.com/thread/3384296?start=0&tstart=0

    I have a question on this (in fact several).  Thus far, Apple Tech Support have proven to be useless, and have no clue (or claim to have no clue) about this issue which I find remarkable.



    Do any of you folk out there experiencing this problem have multiple email accounts synced to your computer?  E.g. A Microsoft Exchange account as well as gmail account??


    I am having major issues with AddressBookSourceSync slowing down my iMac in the office (which runs an Exchange email account only using Outlook for Mac), but also at home where i use mail with THREE email accounts set up - the exchange account from the office (remote access), gmail and my icloud email account.


    Apple seemed to think it was an issue with Outlook for Mac but it cannot be if I am not running this application on my macbook at home......that said, it might be an issue where Mac is trying to Sync contacts from an Exchange email account that it cannot access for security reasons......


    I am not smart enough nor technical enough to figure this out, but hope someone at Apple is able to come up with a solution very soon, as this is killing my producitivity.


    Also, another possible problem somewhere is that my Itunes account is registered to a gmail account, not a mobile me account - - a whole different set of issues in itself.

    Hi Dancsg,


    I also had the problems with AddressBookSourceSync. The 8GB memory of my iMac got eaten up until the machine came to a stillstand. It was impossible to work. Since I know of many people having the same problem, I do not understand why APPLE does nothing to help or cure the cause. Here is a serious memory leak - and Apple ignores it. This is very disappointing.


    Finally I got rid of the problem by following the advice of ISDAY from October 10th. This really works, and the memory eater won't show up again. I still have not understood why, but it helps.


    Certainly, this memory problem has nothing to do with your many email accounts nor with MS Exchange. I don't work with MS nor do I sync many mail account; I just have my iCloud mail account and was badly hit by AddressBookSourceSync.


    Since I made these "corrections" everything regarding sync over iCloud works just fine.


    However, I observe another issue: Also Apple Mail is slowly eating memory during my workday, until the hog is 3GB big. Apparently, here is also something wrong. This does not affect me too much since I have enough memory, but most certainly, this is not he way an iMac should operate.


    I hope this helps.

    ISDAY - I have run your instructions on both my iMAC in the office and my MacBook.  Addressbooksourcesync still seems to run, but is far more stable and not eating my memory.......


    I will monitor it as I am frequently adding contacts etc.


    I really appreciate your input above as this is the only solution I have come across anywhere close.....Apple have not been able to assist me at all with this matter, which is quite concerning.

    Hi Dancsg,


    You will still see AddressBookSourceSync appear in your task list as long as you don't have AddressBook active. But it will no longer eat up your memory. As far as I understood, AddressBookSourceSync does the sync job while the AddressBook task is not active. When Addressbook is active, you will not see AddressBookSourceSync.


    I still wonder if Apple ever will say something to this - perhaps 10.7.3. will cure the issue.

    Isday well deserved. Happy 2012 to everyone.


    By the way I'm bringing one more issue that I'm sure is related. All working ok since, but now when I'm using my address book on MBP under the Icloud contacts using the search option on the top it simply does not browse the list. Not working. Tried everything. It was working before and it ceased. Works fine under the options: all contacts and on my mac but not on Icloud. I have to go and scroll to the desired contact. Very annoying and troublesome.  Anyone having the same issue? Any ideas? Thanks!

    Completely agree Lenskiz.....I've been waiting for weeks for a senior technician from Apple to get back to me....he even sent me his email address, and said 'any further problems sir, just email me directly as we are monitoring this for you'.....ZERO! NO response, nil, nada, nothing.  Six chaser emails later, still no response. So I call and make a complaint.  That was weeks ago - still no response.  Nice to know our Apple Care dollars are being well spent.  Don't get me wrong, I am still a huge advocate of the company, and the products, but when thousands of users (and almost 3000) have now viewed this discussion group, and we, the apple customers discover what I can only assume are massive bugs, and Apple do not even have the courtesy to respond, it's pretty frustrating...


    Isday should be given a medal!  I cannot believe than nobody (out of ten+ engineers) I spoke to at apple could find any materials on their internal support database pertaining to this problem......what utter rubbish.


    HUGELY disappointing.  Up your game Apple.  Steve may be gone, but your customers aren't.

    It seems like everyone else was able to use iCloud again after following lsday's instructions.  When I restarted the sync with iCloud addressbooksourcesync got back upto using 60% of my CPU.  Did I do something wrong?
