• Office sync with two Macs leads to duplicate the files/folders

  Hi all

  I m using MacOS Sierra sync with desktop (and documents). Logged into my account, are two Macs (Air and a MB Pro). No I find in my iCloud drive a documents folder (it's good and the documents of the MB Air folder) and in this case a "Dokumente - MacBook Pro mg" folder which is the folder documents of my MB Pro (this is not so good). This isn't what I expected, I expected to have a documents folder which is identical on both machines. Does anyone know what I need to adjust to get things clear?

  Greetings from the Germany

  Mike

  I posted an article that explains all this to http://www.quecheesoftware.com/iCloud.html . This is a downloadable PDF file.

  Basically, you add to the folder Documents after activation of the synchronization of the files will be synchronized as you expect. But the files that were in your Documents on several Mac folders when you switch on for the first time on the synchronization will be placed in specific subfolders to your new folder of Documents iCloud Drive device. Apple apparently felt that he could not predict how each user would want their old files organized in the folder of Documents Drive iCloud, so Apple left to each user to reorganize the file later.

  I have now moved all my own files on the first level of my folder of Documents Drive iCloud and trashed the duplicate of the other device-specific folder. Now, everything syncs between computers, as expected. I left the two subfolders of specific to the device in place, either two empty for now, in case in the future that I might want to keep some files associated with one of the devices - for example, the alias files do not work on the other Mac. They will always sync in another subfolder, but at least I know to use it only on their own device.

  Apple certainly could have documented it better.

• Firefox problem on one of the two Macs running Mountain Lion

  I just upgraded to Cougar on my two Macs. On the MacBook Air using Firefox 14.0.1 some pages in 'my account' on Amazon site and the portal my.yahoo.com (when connected to the account) are flawed. Note: the portal of my.yahoo.com page seems perfect if you are not connected. It gets only scrambled if you try to display the personalized home page for your account. It is similarly of the Amazon. the general site seems perfect; It is only when you try to view deep pages, such as 'my account '. I've seen problems similar to some other sites, as well. All sites are fine in Safari. Text superimposed on the paragraphs, missing images, etc.
  No problem on the MacBook Pro, also run Firefox 14.0.1

  The reset Firefox feature can solve a lot of problems in restaurant Firefox to its factory default condition while saving your vital information.
  Note: This will make you lose all the Extensions, open Web sites and preferences.

  To reset Firefox, perform the following steps:

  1. Go to Firefox > help > troubleshooting information.
  2. Click on the button 'Reset Firefox'.
  3. Firefox will close and reset. After Firefox is finished, it will display a window with the imported information. Click Finish.
  4. Firefox opens with all the default settings applied.

  Information can be found in the article Firefox Refresh - reset the settings and Add-ons .

• Two Macs can connect to a URL, another on the same network may not

  So far, I can connect this behavior to a unique URL only - but of course, it's an I need to get in order to save some software on this particular machine.

  I emptied the cache, flushed the DNS cache and checked that I use valid DNS servers. It isn't Safari, chrome this brings. Two Macs reached the URL without any problem, but this new model Mac Pro simply will not reach it and traceroute expires after a few jumps. All three machines are on the same network, all three use the same DNS servers. I rebooted several times.

  All three Mac running the latest El Capitan. The two reach the URL are a MacBook Pro and a Mac Mini Server.

  I'm puzzled.

  Please note that a traceroute on all three machines reveals the slowdown even at the same jump in the chain, but only the Mac Pro seems to have trouble with it.

• Can I connect a drive hard thunderbolt to two Macs?

  I have an iMac and my main storage device is a disk hard thunderbolt (double disk RAID).  I also have a mac mini as a server and I would like to set up the service of time machine, but only if it can store backups on the same drive external thunderbolt.  I know there are two ports thunderbolt on the disc, but I guess it can be used only with one computer at a time.  Is this true? Or is it possible to connect the disc both computers at the same time? (Even if it is only used for the service of time machine).

  That's right the led drive only be attached to a single Mac.

  You can have backups from two Mac on disc one hard, if you share the Mac disk drive that is connected. The second Mac then backup over the network to the first Mac who will write the data on the hard drive.

  I was using my MacBook today and it crashed and the dock turned silver, I restarted the mac and it was always the same, then I loaded the disk utility and checked the disk and it says disk is fine. It flashes inconsistently gray and the dock has transformed money! I tried to restore Mac OS and then also the same!
  OS El Capitan

  This can help:

  Reboot safe mode (it is a slow process):

  -stop of the mac

  -Start up the mac in shift, press and hold until you see appear it to progress bar, so you can let go

  -When everything started, connect

  -Once connected, stop the mac once again, nothing else is necessary.

  -restart normally.

• I forgot to turn off to find my Mac

  I erased my HDD on a 15 "Macbook Pro retina to sell to Gazelle. I forgot that I had to stop to find my Mac. I have sign in iCloud online & remove the device from the list of my devices. The unit starts at this point until the configuration screen. Is it enough to turn off to find my Mac? I would prefer not to have to reset the Mac upward again to disable find my Mac only to have to turn around & clear again. I know that there may be a delay to the Gazelle when you sell something to find my Mac power; but I think I did the repair by singing in iCloud & remove device it. The only thing that confuses me is that iCloud reported that if the device goes online again, it will reappear in my list of devices... which it should not. (It's perhaps just a warning for devices not erased after losing, etc.. This is not the case with the MacBook, I sell, of course).

  Can anyone confirm that I did what I should and that things will be OK? (I called Gazelle; but the person tech I spoke with that does not understand the question.) She gave me a link to check the status of an iPhone activation.)

  Thank you

  Robb

  After erasing the iCloud.com device, you should have the option "delete account", this will ensure the new owner has no problem with finding my phone.

• Two Mac license?

  Hello

  I currently have two Macs. At work and at home. Is - this in anyway that I can extend my license on both platforms, I use both on them on different parts of the day. I read up on your message forum adobe it's possible: how many computers can I install my creative cloud apps on?. But when I tried it myself he still wants me to another buy another license.

  Kind regards

  Andre Venter

  Hello

  Adobe license can be activated on 2 machines using the same Adobe ID, but can be used only at a time.

  Please see Licensing FAQ: where can I find the terms of membership and the terms of use?

  You can also see Troubleshooting FAQ: what should I do if I have a subscription, but my application acts as if I had a trial? if you are prompted for the trial.

• VMware device with 2 network cards claiming the same IP address with two MAC addresses

  Hello.

  I see messages intermittent my gateway network two MAC addresses associated with a virtual machine running on a 5.5 ESXi host for the same IP address.

  The virtual machine is a MiTel 3300 controller for a VOIP system. the system is configured with two IP addresses, one on the local network and another with a public IP address in the DMZ. In the network configuration of the 3300, I assigned the address LAN IP at 00: 0C: 29:30:B2:B2 and the DMZ IP at 00: 0C: 29:30:B2:BC (Mac for network devices presented by the ESXi host virtual machine).

  On the host, I configured a vSwitch with exclusive access to two physical network adapters on the host machine. The vSwitch is configured with two machine virtual port groups, LAN and DMZ, with access to the physical network interface cards. Tab grouping of groups vSwitch port NIC, I replaced the order of failover of the switch to activate an active NETWORK card only for the Group of LAN ports and the other card NETWORK only for the DMZ port group. (I don't know how the content of the column of networks is determined. Neither is correct for the traffic on the physical switch. If these are configurable, please advise and I'll change the settings). The relevant parameters of vSwitch, groups of ports and VM are distinguished below.

  On the virtual machine itself, through the VMWare host, I assigned 00: 0C: 29:30:B2:B2 for the Group of LAN ports and 00: 0C: 29:30:B2:BC to the DMZ group port (best I can tell, anyway, since the MAC address field annoyingly obscures the last two digits of the MAC address - break if I invert the mapping) (, but all seems OK).

  The goal here is to make sure that MACs of ports vSwitch the 3300 is listening and sending always correspond to the physical ports that are VLAN Tag by the physical switch to ensure the routing. Generally speaking, it seems that what is happening but, intermittently, we cross one-way calls that suggests a problem of routing between us and our SIP trunk provider; coinciding with these incidents, I get an email along the lines of "the security in the network device has detected a conflict of IP address with two or more devices. The period of INVESTIGATION "DMZ. DMZ. DMZ. DMZ' is claimed by the following clients with MAC addresses: ' 00: 0C: 29:30:B2:B2' ' 00: 0C: 29:30:B2:BC'. »

  I did something in the configuration that would lead to this kind of collision intermittent? Have a hacked together a way to do something that could be accomplished in a way that is simpler and more reliable?

  Thanks for any idea that you can offer.

  Kind regards

  J.

  

  

  

  I probably don't fully understand your configuration, but it seems that you are not interested in using the collection of NETWORK adapters in the virtual switch of the VM MiTel 3300.

  If it is correct, why not create two virtual switches, each with a group of port (LAN and DMZ) unique and with a separate connection of (vmnic2 and vmnic1)?

  In general, collection of NETWORK adapters may be used to share traffic between uplinks and ensure that if one of the uplinks connect fails, a virtual machine still has access to the network.

• My iMac freezes during a turn on and between two switching user accounts

  My 2011 iMac has been crashing for weeks. Usually, it freezes when I turn it on, connect to switching user accounts or user accounts.

  I upgraded to Sierra yesterday and I continued using for hours and it was fine.

  I turned on today; some of the Apple applications do not work... Mail, App Store, Safari (this is what I tried). Responsible mail application, saw a list of emails, but when I click on a particular message, the message will not load. Safari cannot load a Web page at all (I'm now using Chrome). AppStore cannot load anything too.

  I asked for help here before the crash but I was reluctant to share the report of being. Now, I've read about it and understand how it works. The report says "failed".

  Appreciate the help of the community. Thank you.

  It is slow since updated for Sierra.

  A part of which is related to the upgraded Photos app. If you have lots of photos (in thousands), it will take a lot of time for it reach to analyze your photo library. The best thing to do is to let him finish, as long as it could be. 1 hour per 1000 photographs as a rough estimate. When it is finally over, the performance of your Mac will be back to normal.

  Definitely get rid of "Trusteer" however. As a needless "anti-virus" garbage is still installed on your Mac, it is unreasonable to expect it to work the way it was designed to work. Safari won't work. Mail will not work. A lot of other things that you really need to work just won't work. Please read of effective defenses against software malware and other threats.

  Leaving the current Extension is OK but it does nothing.

• Sierra on two macs

  HHas somebody Sierra download experience on two different macs. Mainly the iCloud and office operation of works document? It creates two folders different funds in iCloud?

  Hi, 1192tom!

  Thanks a lot to reach out by Apple Support communities. After reading your post, I understand that you have questions about the operation of the office and Documents with iCloud drive on two separate Macs both running macOS Sierra. iCloud Drive is a great feature to synchronize with multiple devices help content. I definitely want to make sure that you have an understanding of how everything works so you can use it!

  The following article will give you information on how iCloud drive works and help you get set up on all your Apple devices.

  Add your Documents and Desktop files to iCloud drive

  Enjoy the new macOS Sierra!

• can not turn on icloud drive on Mac

  I'm turning in icloud drive on my devices. He succeeded on my PC and iPhone (photo below showing all my folders sync to the iphone).

  Come on in/preferences/bar side of the Finder and check iCloud Drive under Favorites.

• iTunes sync between two Macs

  Newby here: must be a current situation... I have an old iMac from 2004 still purring along and I use it only for iTunes, fuelled an amp for home.  There are about 20 GB of songs.  My 'new' baby is an iMac 2012 also with about 20 GB music.  A large part of the songs are common to both, but many are not.  I would like to sync the two so that both machines have all the songs.  Is not its too difficult for me.  Please tell me it's easy!  That would be a backup for my music.  Otherwise, I need to find all the songs on the new Mac that aren't on the former and copy it on the old iMac for use through the amp.  Please people if you can help.

  No, there is no easy way, especially with one of the Mac's so old and do not have all the characteristics of a new iTunes such as sharing at home or iCloud.

  The only way to merge them is to copy the folder Media from one computer to another (using a flash drive if necessary), add files to iTunes, then spend a day treaty duplicates.

  It would help if you provided more details about the computers, their versions of the operating system, versions of iTunes, if they are connected in a network.  The only way I can think of making some work is if once you have support all in one place, you run separate iTunes library files that correspond to the versions different iTunes you are using, but they point to the media in a central location.  However, they will always have different playlists and adding or removing media must be made by the two libraries individually.
