    Since the installation of EL CAPITAN, I can't open pictures and iPhotos with PHOTOSHOP CS6, nor my mails with office Word

    Hi denisb,

    If you are not able to open the Photos App images directly in Photoshop then, this is the expected behavior as App Photos does not allow for any third-party application interact with it directly.

    You must export images from the Photos App and then open in Photoshop.

  • I can not proceed with the installation of EL Capitan after downloaded because my same unaccepted Apple ID if the correct password overlay

    Salvation;

    I tried to upgrade my macbook pro OS Yosemite to El Capitan, but I can not proceed with the installation of EL Capitan after downloaded because my ID Administration Apple not accepted even if correct password entry.

    By navigating through ' assistance from Apple is in charge to retrieve the Apple ID, I deleted the keychain, now the problem is I can't add the new keychain.

    Please help as I am now hung the message not found "Login" keychain... then reappear.

    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?

    Since the installation of El Capitan, my streaming to my Audioengine DAC D2 cut after 12 minutes (the default duration of sleep). It will restart by pressing the space bar. When I change the duration of sleep, the cut outs are becoming more frequent and intermittent. Help?

    I checked the wifi and changed frequency (new modem, frequency change made no difference). The Board battery seems fine - all updates well. My computer is an iMac (2011), 3.1 GHz Intel Core i5, 8 GB 1333 MHz DDR3, with a new AMD Radeon graphics card. I recently installed a State strong 1 TB SATA drive and fitted with a LaCie Porsche 4 to USB for backup and a 4TB disk storage RAID LaCie drive.

    I'm frustrated, having to come in my computer since my living room every 12 minutes to continue to listen to Spotify on my stereo system.

    My guess is there a bug in the software of sleep in El Capitan, which disrupts his (I've tried different USB ports connect the Audioengine sender and same thing).

    Should I go back to Yosemite?
