Applications do not work after the update!

Last night, I got a notification from the App Store that my MacBook needs to restart to complete the installation of updates. It is fairly common, so I clicked restart and let it do its thing. Some time later, I noticed from upward and go to my office. It was late, I therefore closed my screen and fell asleep. This morning I woke up and went to the pros use, and when I tried to open Mail dock I get the error "Cannot open"Mail"because it may be damaged or incomplete" and the icon has changed to this little pencil 'symbol' I tried some other apps, and it's the same thing. It seems that there is not a single application, I can open it. Every single app gives me this error message. When I open the Finder (the only thing I can open it) and go to the Applications folder, the only two things that are there is an icon of mail (changed on the small pencil symbol) and a folder called "utilities".

To make things worse, Time Machine worked right for about a month, so I do not have a recent backup. I keep a sense repair or find a better backup program, but I don't have the time. My main concern is that all my music (from iTunes) files are still there. When I browse it in the Finder, it seems that all the files are still there. He Spears is only my applications that don't work... but he's literally all alone! Is that what I can do about it? Please let me know if anyone has an idea of what's going on!

If you want to keep the data on the boot disk, and it is already saved, you must try to save now, before doing anything else. It may or may not be possible. If you don't care the data, you can skip this step.

There are several ways to back up a Mac that is not fully functional. You need an external hard drive or other storage device to store the data.

1. start the recovery partition, of the recovery of the Internet or a local time Machine backup volume (button option key at startup). Launch the disk utility and follow the instructions in this support articleto the title of the "Instructions for the backup on an external hard drive via disk utility". The article refers to the start of a DVD, but the recovery mode procedure is the same. You don't need a DVD if you use OS X 10.7 or higher.

If you use FileVault 2, you must first unlock the boot volume. Select its icon ("Macintosh HD", unless you have given it a different name.) It will be nested under another icon of the drive, usually with the same name. Select open in the file menu. When you are prompted, enter your login password.

2. If method 1 fails because of disk errors, then you can be able to save some of your files by copying them in the Finder. If you already have an external hard drive with OS X installed, the start of it. Otherwise, if you have access to the Internet, follow the instructions on this page to prepare the external hard drive and install OS X on it. You will use the installation program of recovery, rather than download it from the App Store.

3. If you have access to a working Mac, and she and the non-working Mac FireWire ports or Thunderbolt, start the Mac non-working in target disk mode. A MacBook to the retina (2015 or later) with a USB - C port can also be started in target disk mode and connected to another Mac using a USB cable and an adapter.

Work Mac to copy the data to another drive.

This technique will not work with USB (except on a MacBook of the retina), Ethernet, Wi - Fi or Bluetooth. Note that a MacBook Pro (with Thunderbolt) retina is distinguished by a MacBook to the retina, and it cannot be connected to another Mac via USB in target disk mode.

4. If the internal drive of the non-working Mac is replaceable by the user, remove it and climb into a docking station that is pregnant or an external drive. Use another Mac to copy the data.

This procedure will remove some temporary and cache files. The files are generated automatically and do not contain any of your data. Sometimes they can become corrupted and cause problems like yours.

Please, back up all data.

  • Delete buttons do not work after the update of 10.11.16.

    Delete buttons do not work after the update of 10.11.16.  The delete button works if I pointed out and then delete, but not if I use the "back" button or try a removal of uniqueness.  It is a problem in all applications.  I tried it in textedit, search google chrome, safari search and find finder engine.  There seems to be a 'problem' of the keyboard' as far as I know nothing happened to my keyboard, IE the spilt coffee, that recent warming has been updated to 10.11.16.  I use an iMac (27-inch, late 2009) with i5 clocked at 2.66 GHz, running OS X El Capitan.

    Any suggestion would be appreciated.

    Greetings, r.fromstouffville!

    It seems that the 'Delete' on your iMac keyboard key works as it is supposed to be after update to OS X 10.11.6. I'll be happy to help you get these keys working again.

    Reset of the controller management system (SCM) on your Mac - sometimes it's a matter of simply resetting your iMac SMC. Open this article and scroll down to "Reset the SMC on Mac desktop" section and follow the steps there.

    Try safe mode if your Mac does not start -even if your iMac, safe mode startup make sure it starts successfully.

    How to test one question in another user on your Mac account - use this article if restarting in safe mode did not help.

    Use Time Machine to back up or restore your Mac - if your keyboard does not always work as it should, I recommend you save your iMac to ensure that your personal data are safe. It is always better "to have" a backup for a backup "need."

    On OS X Recovery - if you have reached this point, you encounter the same problem in a test user account, that would mean it is a system-w. Start your iMac into Recovery Mode and reinstall the operating system.

    Thank you for the communities of Apple Support!

    Hey delittle632, this is probably due to the recent update of the plugin to version 11.3 adobe flash. It has caused similar problems for many other users (chrome & IE get provided with a different version of the plugin by adobe).

  • TOSHIBA DVGW/HD TS-L802A-ATA do not work after the update to Vista SP2

    Hello

    I run Microsoft Fix It (http://support.microsoft.com/gp/mats/?ln=en) + "your CD or DVD drive cannot read or write media.
    But it has not solved the problem.

    I download and run the Microsoft devcon command-line utility.

    I guess that this lower filter of "tdcmdpst" (the writing of TOSHIBA motor filter driver) is the issue.
    But I can't remove the filter 'tdcmdpst' even with admin rights.

    DevCon has failed.

    How can I remove this filter to upgrade Vista SP2?
