• After the upgrade to El Capitan cannot insert CD/DVD in external drive

  Hello

  I have a Macbook Pro (mid-2014 retina) and I have this problem since I upgraded to OS El Capitan. Now I have the last 10.11.5.

  I can't insert a CD/DVD in the external DVD drive. It gets stuck at the end when it is like 80% already.

  I searched on the web before and there was a workaround solution that you put the CD in and reboot and it would work and it is indeed, but it's a pain that every time I work on the Macbook and in the middle of something and I want to insert a CD that I have to close everything and restart to get the disc inside!

  Once I do that, it works fine and I can eject and insert it again normally, but the first time I have to restart first, and since it's an external drive, I have connected it all the time, so whenever I connect it, I have to redo this same process.

  I was hoping with the last update that this problem could have been resolved for me obviously it's a software problem because it came with the upgrade to El Capitan, I've improved in later, but still problem is there. I hope that someone would have reached a permanent solution for this and I would be really grateful to know it.

  Thank you!

  The external drive does the same thing on a different computer, be it mac or windows? Also is what brand?

• El Capitan loaded on my external hard drive disturbed my system preferences Maverick on my drive internal

  I currently use the most recent version of Maverick from an internal hard drive on my iMac. I needed to download the demo of Final Cut Pro X or under of El Capitan Yosemite and due to a limitation of version of FCPX. As I had an another Maverick boot on an external drive, I've decided to upgrade this drive to El Capitan. A few hours after the installation was successful, and I was able to download the trial of FCPX. So I planted my system and restarted with my boot Maverick my internal drive. So far so good, however, to my surprise, I can't the system preferences window because it gives me the following message appears "Unable to open the preferences system because of a problem.". Similarly, I get the same message when I load a DVD and the DVD player will automatically load.

  I need to go to my applications and open the program individual (Preferences system and DVD player to do what I want to accomplish.

  I restored tOSX recovery Mignot, but nothing has changed. I believe that El Capitan installation on another drive has created conflicts.

  I also discovered that my backup should be completely redone (i.e. backup lull in my go 530)... beautiful!

  Someone has a similar problem?

  If I can't solve this problem, I have to install El Capitan on my internal drive and maybe the problem will be solved.

  I would eject the external hard drive with the installation of El Capitan and see if it helps.

  FWIW, I have never known or seen reported when an installation on an external drive also changed the preferences on the internal drive.

  I suggest that you eliminate problems in your user folder by checking in the comments or in a new user.

  CREATE A NEW USER

  Go to system-> Preferences, create a new user in users and groups.

  Place in the new user by logging in under the Apple in the menu bar.

  Log in to the new user.

  You can ignore connect them with one identifier Apple. Hit continue and then jump.

  Only applications Apple will be on the dock.

  Go to Applications to open other applications.

  You still see the issue?

  If Yes, then the problem is with your core files.

  If not, then the problem is in your user folder.

  You have the time Machine and internal backups of your disk clone?

  I have a 27 "iMac Intel i7 El Capitan running. I also have a still-good G5 that I use every day. I want to (re) install 10.5.8 on the G5, because he had a hardware failure and start the system has failed. I removed the hard drive to start the G5 chassis, put it in an external hard drive enclosure and that connected to the iMac. Disk utility indicates that the drive is OK. The idea was to make the external start G5 drive temporarily, install the OS then remove the external hard drive chassis and put it back into the chassis of the G5. USB external hard drive boot G5 drive is loaded right now is, I don't have the installation provided with my G5 discs.

  I have a 10.5.8 install image I d / Apple editing, but when I run it, he said "this software requires Mac OS X 10.5 to install.

  How can I convince the i7 iMac install 10.5.8 on this external drive?

  You need a compatible installation DVD to perform the installation on the G5 and connect the drive to the computer internally or through FireWire.

• El Capitan and the external drive is no longer compatible. Why?

  El Capitan upgrade is complete. Now Mac does not recognize my "WD Book Essential external drive" which is not complete. Tried 20 times. Icon WD Book appeared on the desktop once. Bkup began, it stopped! Time Machine displays "Unable to complete backup" and cannot get the icon to reappear on desktop. Stop Mac, unplugged, used different usb port, different electrical outlets... what else?  The USB cords very well. Y at - it an upgrade of Mac to run the connection? Cannot test it on another computer, none are available. BK in last place on 12 / / 15. Help, please!

  It may be a physical problem with the drive. Try this...

  Launch/Utilities/Terminal and copy & paste this command at the command prompt:

  diskutil list

  Press return.

  If it sees the drive, note the number of the disk (left column) that you want to mount.

  Then enter this command:

  Mount /dev/ (number of disk)

  Put the number without parentheses.

  Press return.

  Also can try

  mount/dev / strength (number of disc)

• Cannot read iphoto library stored in an external drive, after the installation of el capitan and photos

  What size is the drive? How are you connected to it?

• Can I make a backup of my time on a second external drive capsule

  It is perhaps an exaggeration, but as I have a Seagate external drive, I thought it wise to make a second backup. Is there a procedure that I can set up to automatically duplicate what I save on my TC.

  I run a 27 inch mid 2011 iMac with the last OS of El Capitan. I use my Time capsule using the airport on 12 hours automatic backup.

  Can I make a backup of my time on a second external drive Capsule

  Yes, you can... but the procedure will not "auto".  Connect the hard drive to the USB port on the Time Capsule and use the Archives in the utility AirPort.

  

  This copies everything on the Time Capsule on the USB.

  Upside down... you have a copy of all of your backups on the Time Capsule. Downside... you must check manually... and... f there are problems with the backups on the Time Capsule, these same questions will be copied on the USB.

  IF... connect you the player to the USB port on the Time Capsule, rather using the manual function Archive... you don't have the opportunity to have Time Machine backup automatically at a time Capsule of time and the USB on the Time Capsule.  Time Machine automatically alternates backups from one disk to another.

  Even better, more reliable and much faster would be to connect the USB directly to your Mac and have Time Machine automatically backup the disk in addition to the time Capsule.

  There are other options of backup as well, but they would not be using Time Machine.

• After installing macOS Sierra. There is no disk external drive appears on the desktop.

  The external hard drive still works on macOS El Capitan, but after I installed the new operating system the drive doesn't appear on the desktop. But I found it appears on disk utility. How should I solve this problem?

  • I used the iMac (mid 2011).
  • I tried to restart but still problem.

  

  Is the option to display external drives on the desktop yet activated in Finder preferences?  Check the Finder preferences.

  

• Independent external drive for Time Machine backup

  Can I save two external hard drives independently in two separate backup drives?

  2 TB DHM supported with a 2 to DHM

  and

  5 to DHM supported with a to 5 DHM

  The 2 TB drive holds the content inventory which changes often but never amounts to more than 300 GB.

  5 TB disk holds archived folders which adds, with about 30 GB of data, once a month.

  Time Machine is not really suitable for this. The only way I can see it could do would be to an installation to be excluded from the backup disk, then do the backup Time respective Machine. Then return the exclusion so the opposite road is excluded, then backup to the backup Time opposite Machine.

  This should be clear would be a completely manual process, in fact you realistic would switch off the Machine in time to avoid that it auto backup on the drive bad between manual backups.

  However other backup programs more sophisticated pourrait be configured to do this automatically.

• Copy of iPhoto/iTunes to external drive for upgrade

  I would like to transfer my iPhoto (5.0.4) and files iTunes (9.2.1) of my old iMac G5 (running 10.4.11) to my new iMac (El Capitan running).

  My iTunes library is now on an external drive (and iTunes is headed there), and I would like to copy my iPhoto on the same drive - to move together on the new iMac while maintaining the structures of files etc.

  Can someone tell me what is the best way to do this? I'm not clear what iPhoto files files, I need to move or copy on the external hard drive to retain the current structure of the organization/etc folder or the process then bring them into the right place on the new machine.

  Simply drag and drop them where you want libraries to reside. As iPhoto is plu included you will use the Photos app. You can learn how to move the library iPhotos to Photos for Mac on http://osxdaily.com/2015/04/17/move-iphoto-library-to-photos-mac/.

  Insofar as your iTunes library, yet once just drag and drop. 'Teach' iTunes where the library is simply double-click the library and iTunes will find it and then "know" where the library.

• Could not open any project or external drive backup files

  Hello world

  The way I got things set up, is that my final cut pro project has been saved on the external drive. Whenever I open it, it picks up from the external hard drive. Recently, I had a power outage that stopped my external drive and crashed my FCP X. When I turned things on, I kept getting an error that the FCP closes unexpectedly. I have the option to ignore or to reopen. I tried to open my backups, but I get the same error. Sometimes he was telling me to save it to the internal drive and it would actually open, but I get a lot of lack of links to files. My mac doesn't have a lot of space, so I need to be stored on the external hard drive.

  I thought that maybe it's my sharing and permissions of the drive in the menu get info, then I have everything given access, but does not work. I tried trashing the preference of the FCP, but that did not work.

  I have version 10.2.3 and on Mac OSX 10.11.6 El Capitan

  Could someone help me please? I don't know what else to do.

  If outside go up OK, can find you the library problem, right click on the library icon and select

  Display the contents of the package.

  You can post a page please?
