Distnoted and Time Machine problem

Since the update to El Capitan, I had a real problem with the stability of the iMac.  From time to time - a couple of maybe days, three times a day, maybe - it would just freeze with BBOD on the login screen.  So, in general, after wake from sleep or screen saver.  Execution of SSH on the iMac would show distnoted clocked at > 380%; kill that process would be to release all.  He seemed to be repercussions for this purpose - for example, Time Machine, notifications would stop appearing - backups work (depending on the Console) would simply not be notified.

Anyway, I actually had my TM drive disconnected for more than a week now, and the problem occurred.  So it seems to be one of the three possibilities:

  • bad interaction between distnoted and TM or processes
  • defective drive.  It's a mobile hard drive from Lacie P9223 (but I also have a second desktop Lacie drive that causes the same behavior).  Disk utility shows no problem with either of the readers.
  • bad driver/firmware.  Maybe... in light of the same manufacturer.  I tried the update of the LaCie firmware but it just does not recognize the plugged into readers - I assume that the update is for one or more different models.

Short run out and buy another drive from a different manufacturer - and who knows how different the internal components are really - someone has an idea how I could continue this?  Everything was ok before the upgrade; I remember that with a previous version of OSX external drives popular of some manufacturers stopped working, I had this problem at the time.

Determine if the same problems occur when running in "safe" mode: OS X El Capitan: start in safe mode

  • External hard drive to format HFS + (not OS x) and Time Machine boot

    Hello, I have a MBP of 2014 (10.11.2).  Have a 2 TB external drive SG was NTFS but reformatted using THE HFS + and created two partitions of 1 TB (Yes, for my intended purpose in hindsight should have apparently formatted to a ready drive "Time Machine").  But just went with HFS + and Time Machine is ready to use one of the partitions to backup nonethelss.

    Hmm... but 1) TM do not encrypt, and more important again, I wonder if TM 2) can perform full restore from a drive WITHOUT the OS X on the ext drive (no matter the format HFS + appropriate)?

    (FYI, I received a warning when you use CCC related attempt to clone the drive to this disc hard ext, but received a warning "not re-bootable from any OS X").  Thank you!

    HFS + Mac OS Extended is what should be the disk.

  • Difference between Seagate Plus backup and Time Machine?

    Can anyone tell me what the diff between backup and Time machine?

    I started and this next screen (see below).  This means that the Seagate Plus backup will replace Time Machine?  Or he supplement TM?

    I'm afraid that if I select "Use as backup drive", I might regret it... then I would understand.


    If you use Time Machine with your Seagate hard drive, say Yes.

  • Problem restoring stuck MacBook Pro system and time machine

    This morning my retina MBP (El Cap 10.11.4, updated about a week ago) has frozen. It was working fine yesterday, but wake from sleep this morning nothing would go, apps wouldn't start, nothing, so I rebooted. He got about a third of the way between the progress bar white on black screen and hung with a spinning wheel.

    Then I tried to secure boot and made me to the login screen, but it still turns after that I entered the password. (The guest account and the other I put in place but rarely use seem to work well, it's just me hanging). Reset NVRAM made no difference.

    Then I went to recovery mode and has conducted an audit of disk first aid, who reported no problems. So, I used the disk utility to make a disk image to backup to an external drive and then to the Time Machine system restore. However, it asks for the password for 'System administrator' and rejects everything I try. The TC is configured as "Discs safe with accounts" (not ' device password') and there are two custom accounts and the wifi password. I can't check my backup settings now, but I think that it is only for my account, so I wonder if even is a system restore file. I would try to change the airport disk access settings but I'm afraid it will just trash my backups.

    Suggestions for free my Mac or enter the system restore (or restore just my account) until I try a reinstall?

  • The airPort Extreme (2007) and Time Machine

    Hi all

    I read the info "how to ask a good question" and apparently you need details. I'll try and be concise but informative with my problem. It has been a long journey to get to where I am, but hopefully, with a little help from this amazing community, I can get to my destination.


    To produce a backup solution Time Machine for the family spending as little money as possible and using the BRIC and broc, I already have.

    Equipment available

    I have a House with some ethernet cables for most rooms that through switches to allow a variety of, most entertainment devices to communicate. It is:

    1 x NAS/Media (ReadyNAS Duo v2) server,

    2 x TV (Samsung),

    2 x TEU (Beyonwiz),

    2 x Apple TV (a 2 nd generation the other is the latest version)

    2 x DVD players,

    1 x iMac.

    2 x 8-port switches,

    1 x 16 switch ports,

    1 x AirPort Extreme (2007).

    1 x Airport Express (age unknown but older than the extreme)

    1 x Fritz! Box 7490 Modem/Router

    Courses in place

    All the associated TV stuff are connected in 2 rooms through ethernet via switch 2 x 8 ports switch 16 central port and then to the Fritz! modem/router box.

    There are also all the usual WiFi going on with mobile phones, iPads and laptops.

    Remarkably, it seems just to work!

    However, I want to add some backup data on our computers. I tried to do by using the ReadyNAS as it is supposed to support Time Machine, but I can't it to appear as a backup destination. So, I thought, as I have AirPort Extreme, I add it to the network and attach a USB HDD for Time Machine since it is supposed to be easy. However, I've been home for hours and cannot make the HARD disk appear in system preferences/Time Machine.

    I plugged the Airport Extreme in one of the switches 8 port said to create a wireless network with the same details as the Fritz! The box according to another article of the support (Airport Extreme wired AND expand network - need of entry). Airport utility shows me Wi-wired connections and seems to work.

    I look at the AirPort Extreme disks tab and can see the attached USB drive here. However, it does not appear as a choice of drives available for backup in Time Machine preferences. I tried 2 different discs with the same result.

    The Question (finally)

    How can I get Time Machine preferences to show the USB disk attached to AirPort Extreme as a valid choice for backups? If anyone can give me a little help in the right direction, I would be very grateful.

    Thank you for reading this,


    Unfortunately, the key here is that the version of AirPort Extreme you have does not officially support Time Machine backups on a drive to the USB port of the device.

    The only version of the AirPort Extreme, which will officially support Time Machine backups on a drive in the USB port on the airport is the 802.11ac current version that looks like a "tower". Older versions of 'flat and square' of the AirPort Extreme don't support Time machine with a USB drive attached.

    To check, please see "Time Machine in charge of USB drives" in this Apple support document... AirPort base stations: discs on USB - Support Apple

    Support for time Machine to USB drives

    OS X Time Machine supports compatible USB drives encrypted, related to the time Capsule (802.11n and 802.11ac) AirPort and AirPort Extreme (802.11ac).

    Given that the average life of most wireless routers lasts about 5 years, and your AirPort Extreme seems to be about 9, your AirPort Extreme did very well for you... much better than the average. It might be time to start thinking about a replacement who will be responsible for backups Time Machine... either a time Capsule (i.e. an AirPort Extreme with a built-in hard drive) or another AirPort Extreme.

  • External hard drives G and Time Machine

    The issue of the 'readers G' does not complete the back-ups to Time Machine has been resolved?

    You will need to contact G-Technology in this regard. It is not a known problem of Time Machine. Do you repartition the drive using the GUID and the reformat Mac OS Extended journaled? You will need to do if you want to use with Time Machine, otherwise it will try to use the backup software pre-installed.

  • El Capitan and Time Machine

    First my setup. I am El Capitan running on my Mac Mini. My House is hard wired Cat 6 for a central switch. I have a 1st gen Time Capsule to the location of the switch to connect the Ethernet switch and he also manages the wi - fi for my wireless devices.

    With the previous operating system, I was always able to perform a backup Time Machine to my Time Capsule via Ethernet. I've always had the WiFi on my Mac Mini turned off.

    Given that the upgrade to El Capitan, the only way for me to make a Machine time back to the time Capsule is to have the Mac Mini wi - fi and the Time Capsule wi - fi enabled.

    I would go back to just having the wi - fi Time Capsule as the single active wireless. I don't know what the settings changed with the new OS install or if Apple changed something. I'm not so sure that the Mac Mini is using Ethernet or wi - fi to access the internet. I can unplug/turn off either and access still works, but on the Time Capsule backup only works if the WiFi is enabled to the Mac Mini.

    Hope someone can solve this problem for me.

    Thank you


    Is the time Capsule also your router home, or just a Wi - Fi access point?

    If only an access point Wi - Fi, it is configured in Bridge mode?

    If you have another home router, and the time Capsule is not in addition to the bridges, it also acts as a router with its own subnet.  This can interfere with the ability of the Mac mini to connect to the time Capsule.

    Just a thought.

  • Formatting the HD and Time Machine backups

    My drive external hard Time Machine seems to be failing am so anxious to save my TM backups. I've already lost a few videos which was on a 40 GB partition, but backups on the 'main' score seem ok. In another thread, I discovered that the problem I have copy backups TM externally to another drive on an iMac is a problem because my MBP is formatted Mac OS X extended suburbs and the iMac is formatted Mac OS X extended (journaled).

    So, if I have reformatted the HD (journaled) MBP could reinstall Mt? or TM comes with original formatting?

    I think I have my answer. Looking through the guide of TM of Pondini I see that there is NO possibility of progress as I'd hoped.

    Since it is my laptop computer (MBPro) and information/data cannot be compromised, then it's time for a backup to disk somewhere image. It's just about 200GBs, then I'll have more information TM and hopefully again in the disk image.

    Once I have done disk image I'll reformat the hard disk, reinstall El Capitan and drag/levitate things of the image and/or the TM to backup and I hope have my machine back as is (but with good formatting).

    It is difficult for me to believe that 5TBs of storage here and there and it is not enough.

  • Upgrade to Snow Leopard and Time Machine

    Hello. I found this topic in an old topic, but it has been blocked so I couldn't answer. Here is a new.

    I have a fairly old MacBook Pro... mid-2007. Provided with Tiger. Upgrade to Leopard in 2010 or more. I want to now upgrade to Snow Leopard and make a complete installation where I have completely clean the existing hard drive.

    I did the Time Machine backups for about four years on my external hard drive. When I install Snow Leopard on my MBP, I can just do simple drag and drop the kind of things from my external hard drive on the hard drive of the MBP?

    For example, once I've erased the hard disk of the MBP and do a new installation of Snow Leopard, can I then connect my external hard drive, open a certain folder and something like Pages slide window of the HD to the window of the Applications on my MBP?

    Thank you!

    Drag and Drop could be a problem, because these applications and files will not be usable unless they are properly updated. It would be better to have a clean install of Snow Leopard and then use the Migration Assistant to transfer files from your Time Machine backup. Note that Snow Leopard will ship with the Apple apps so they do not need to be transferred. You can check with 3rd party developers to ensure the compatibility of their software and upgrade options.

    It is with the Migration Wizard:

  • Sierra Mac OS and Time Machine?


    Since the update for Sierra, time machine takes really long in the "preparation of backup." I was not able to save my mac since. Can someone tell me why this is happening and if I'll ever back on my mac?

    The first backup after that an upgrade of the OS can take a long time, leading people to think something is wrong. Sometimes, something is wrong - maybe it's a coincidence, but I think it's during these periods of preparation time that a TM backup is more likely to stall. So the first thing to try is defined the computer don't not sleep and manually start a backup of the day after. If this good return. If this is not the case, the second thing (if you can't wait go to this step) is to open the TimeMachine backup and open the backup.backup folder and the folder of the computer to find the actual backups. You should see a file called 'ongoing' remove it. (I open open TM preferences and turn off TM before doing this.)

  • QNAP and Time machine

    I have a QNAP NAS and iMac running El Capitan 10.11.

    I can't get time machine to connect to my SIN more, I read that apple has stopped supporting it.

    If someone can confirm this?

    Apple continued to support NAS. There is, however, apparently a bug rearing its ugly head from time to time between updates of El Capitan. Apparently started in 2015 with the release of El Capitan 10.11.3 and continue for SOME users. Some report that they must manually 'connect to server' to get the mounted SIN. The best advice at this time are to ensure that you are on the last update of El Capitan that is 10.11.6. Search these forums for other users have developed workaround solutions.

  • Airport Extreme and Time Machine

    Two questions:

    I have a 2nd generation (I think) Time machine. Network performance is slow throughout the House. MacBook Air, iPad, iPhone, etc. In addition, we have internet high speed ugly (country life). The new Airport Extreme upgrade will speed up my network? Also if I buy AE without Time Machine can I use always current Time Machine for backups and not as a router? Running Mac Mini end of 2014.

    If the seed is limited by your internet provider then a new router will not help.

    Try to connect to a Mac via a cable (Ethernet). That will help determine if update will help your wifi router with internet high speed.

    An Airport Extreme includes NO storage. Apple's time Capsule incorporates an Airport Extreme and a hard drive for storage in a single package/case.

    Even if you bought a time Capsule you sill use your existing storage unit for your Time Machine backup

  • Time Machine - problem of reformatting drive


    I recently started to use a new external drive for Time Machine with encryption. I want to encrypt another drive that I used for Time Machine for several years without encryption. So, I went to Disk Utilities etc and reformat the drive. Everything seemed to go well, except that when I open the time Machine (and he does this thing 'Dr Who' from the 1970s!), it seems to be 'remember' some previous backups, even if she won't let me access it. Surely, the reader could not have been formatted properly.

    I advice in public services, watch the disc has two 'levels', both of the same name--as if 'a folder in a folder '. I guess that this concerns the drive with a partition, but I'm not sure. The "bottom" element can be reformatted, but cannot be the top element. I want to delete all of the disk and start over. Please can anyone advise me on what to do / what am I doing wrong?

    Related to this: I noticed that the disk can be encrypted in the disc utilities when formatting, even though I had ignored that and it costed in Time Machine instead. Does make a difference?

    Thank you!

  • Several laptops, external wireless and Time Machine

    I have three MacBooks, I want to connect it to Time Machine, but getting three external wired systems is not going to work. In my family, no one sits in a single place that would connect to a device.

    However, I'm trying to find out if I have three machines use a single external for three different instances of Time Machine. My first thought was that I could divide a disk into three partitions of 1 to 3 TB, but I called their customer service and they said that partitioning would not work. However, I can create three separate 'folders' that work with the separate MacBook. I didn't think it was possible. When I used TM in the past, and I use it connected to a G5 tower, he formatted the drive especially for the backup. And I have not found any instructions on the use of sections of a player.

    Before that I have to spend money, I wanted to make sure that it is possible to what they describe.

    You can bind Time Machine in specific folders on an external?

    If someone has a different suggestion, which would be also welcome.

    Thank you.

    You can bind Time Machine in specific folders on an external?

    Yes. I save 2 computers in a time Capsule that is not partitioned.

    Apple officially supports the time Capsules for network backups. If you look in the section updated the Apple store, you can get one for a reduced price with the same warranty as a new one. After trying a few other brands for the backup of network backups, I went to all the time Capsules and in my experience, they work.

  • Spotlight and Time Machine


    Recently I re-indexed my hard drive using Spotlight, after that it went all blue for a TM back upward. The result wasn't perfect, but it was close.

    The Mac went to Apple yesterday for diagnosis and spent all the things. Hard disk, file system, etc. I went home after that and a few updates for iTunes, Pages, Safari.

    As TM had new things to watch over it, each drive took about 20 minutes.

    Then, about this Mac then showed 20 GB of apps after a report of 10 GB (I have less than 9 GB system apps). I went home at lunch to work, ran a TM until I stop, as always, now, Apps 24GO shows about this Mac. It seems to move the 'other' "apps".

    I know that the GUI is often false. But, as before, it seems to change after I run Time Machine.

    Any wisdom out there? The last re - index held well for a few months until all updates and diagnostics yesterday at Apple.

    Thank you
