iMac will not be stopped after installation of El Capitan

My computer shuts down after upgrading to El Capitan. I did some research and discovered that I have to remove avid CoreAudio.plugin of my plugin folder, but when I opened this file is not there. Is there another solution to this problem?

Try resetting the SMC reset management system (SCM) controller on your Mac - Apple Support

If you need to force close to the bottom of your iMac do it now the power button for about 10 seconds.

    ===========================================

    Think about it an absolute must - manually update your drivers.

    Vista and Windows 7 updated drivers love then here's how update the most important.

    This is my generic how updates of appropriate driver:

    This utility, it is easy see which versions are loaded: run DriverView - set
    SEE drivers to hide Microsoft - update those with Dump in their names. (Also
    updated the BIOS and drivers from the chipset on the site of the constructor/the system motherboard).

    -Free - DriverView utility displays the list of all device drivers currently loaded
    on your system. For each driver in the list, additional useful information is
    Poster: load address of the driver, description, version, product name,.
    company that created the driver and more.
    http://www.NirSoft.NET/utils/DriverView.html

    For drivers, visit Maker as replacements and system manufacturer of device which are
    the most recent. Control Panel - write - graphics card - device manager
    the brand and complete model of your video card - double click - tab of the driver-
    Note the version information. Now click on UPdate Driver (this can do nothing
    MS is far behind the certification of drivers) - then do a right click - Uninstall - REBOOT
    This will refresh the driver stack.

    Repeat this for network - card (NIC), Wifi network, sound, mouse, and keyboard
    If there are 3rd party with their own software and drivers and the other main device drivers
    you have.

    Now, go to the site of the manufacturer of system (Dell, HP, Toshiba as examples) (restore)
    and site (Realtek, Intel, Nvidia, ATI, for example) and get the manufacturer and device
    their latest versions. (Look for the system to update the BIOS, Chipset and software updates
    Site of the manufacturer here.)

    Download - SAVE - go to where you put them - right click - RUN AD ADMIN -.
    REBOOT after each installation.

    Always check in the Device Manager - drivers tab to be sure the version you are
    installation actually appears. This is because that some rollback of drivers before the
    later is installed (particularly that audio drivers) so install a driver - reboot.
    Make sure that it is installed and repeat if necessary.

    Repeat to the manufacturers - BTW to the device makers DO NOT RUN THEIR
    SCANNER - check manually by model.

    Look at the sites of the manufacturer for drivers - and the manufacturer of the device manually.
    http://pcsupport.about.com/od/driverssupport/HT/driverdlmfgr.htm

    Installation and update of drivers under Windows 7 (updated drivers manually using
    the above methods is preferable to ensure the latest drivers from the manufacturer of system
    and device manufacturers are located)
    http://www.SevenForums.com/tutorials/43216-installing-updating-drivers-7-a.html

    If you update the drivers manually, then it's a good idea to disable driver facilities
    in the updates of Windows, which leaves on Windows updates, but it will not be installed
    pilots who are generally older and cause problems. If updates provides a new
    driver then hide it (right click on it) and then go get new ones manually if
    you want.

  • I accidentally deleted iPhotos after installation of El Capitan and were not able to download or reinstall.

    I accidentally deleted the iPhoto app on my new mac after installation of El Capitan and are not available for download, except the updates, which obviously doesn't work. How can I get that back?

    You can probably not - most likely, you will need to switch to Photos (what would happen sooner or later anyway)

    Have you looked under purchases in the app store?  Can't update iPhoto because it is not available in the App Store

    If it is not there you can try reinstalling iPhoto 11 of the original source and the upgrade to 9.6.1 but I doubt it will work

    Or you can try to restore your backup from just before you shape did this error

    Good luck

    Thank you

    Mel

    Okay, so you didn't get very far in the installation.

    Here's how to reset a forgotten password.

    Do you have a backup before the upgrade, such as a time Machine backup?   (Keychain is not containing the administrative password, unfortunately.)   You remove the login keychain, all stored passwords in Safari and in fact be lost.)   If you have, I would recover the set of connection from there.

    If you don't have a current backup, it's the first think you get.

    There could be a problem with the disk or of protection structure, or with the disc itself.    Creating a new keychain cannot be blocked, short error permissions or a drive problem.    Disk utility and check the drive and see if there is something to do.   (Unfortunately, some of these steps require an administrative password.)   You can try the repairs or a backup to disk by booting from the recovery partition - that won't require no administrative privileges - and attempt a repair or recovery from here, or save the entire drive disk external work.

    You have another Mac around, where certain tools can be generated and can then be used here?
