I did disk first aid and tonight, tried to do a reinstall in Recovery Mode. I went into Recovery Mode, but nothing after that I said to reinstall Sierra (in fact he said that he would check if I was eligible, then I hit Continue, and nothing's happened over an hour when I left).  I also downloaded from the App Store, reinstalled Sierra and have exactly the same problems. But I'll try fortunately once again in a day or two after your specific guidelines, and it would be nice if it worked.  (I had all of your problems. Mine were the window of the mail attachment issues (opens and closes quickly or opens but not completely, so I can not upwards), network goes offline after I wake the computer from sleep, sleep sometimes takes three tests since the first time I try to sleep, he wakes up immediately.  But I'll give it a try and thanks to you and khati for the info.

  • IMAP Yahoo problem with macOS Sierra

    Salvation and for reading.

    After having upgraded to Mac OS Sierra, I got the following surprises:

    All my IMAP from Yahoo email account are not synchronized more when stocks are made on my mac.

    IE: if I delete an email on my iPhone, it is deleted on the mac aswell. If I delete an email on my mac, this email remains on the iPhone as no action has been taken.

    Of course, it's a big problem because I get tons of emails that I proceeded normally on my mac.

    Any help please?

  • MacBook Pro (15 inch, end 2013) with MacOS Sierra 10.12: kernel_task maxing out CPU with external display

    I have a maxed out end 2013 the MacBook Pro Core i7 to 2.6 GHz, 16 GB of DDR3 RAM, 1 TB SSD, NVIDIA GeForce GT 750 M 2048 MB, Intel Iris Pro 1536 MB.

    Also, I have a DELL P2415Q Display 24 inches (3840 x 2160) using Thunderbolt, are involved through the headphone jack and use a USB for lightning to recharge my iPhone.

    I upgraded to macOS Sierra the day he is released and had no problems until this morning. I unplugged my external screen and speakers and used my laptop for about 15 minutes, the battery, and then returned to my office and plugged my Thunderbolt, rear speakers display in and my CPU shot at 100% and never came back down. My Mac is essentially useless because kernel_task is eating all my CPU and to prevent another asks to enter the CPU.

    I have since audited equipment - everything was fine, reset the NVRAM and I tried to erase IOPlatformPluginFamily.kext .plist files but I couldn't on my Mac (trying to follow this guide, started in Safe Mode and everything then went to try and find the file and my Mac just does not have it). When my external screen is plugged if I'm doing anything CPU intensive (videophone, opening of Chrome, etc.) then my kernel_task gets mad again, and the only way to move is to unplug my screen. Connect my iPhone to charge the tips also my kernel_task as well. I followed my internal temperatures, and nothing was out of the ordinary, to cold currently at about 140 °.

    At this point, it seems that any time that puts something on the charging system and increase the temperature internal internal components of my Mac kernel_task maxes my CPU, which brings my Mac to its knees.

    Any ideas how to fix? Is this just a major bug in 10.12?

    So I got my new Motorola Droid 3 back in August 2011, I think that I don't really remember the exact date. But since I got it I really have not had any problems with it. A few times he has not desire to market even if it was fully charged I jumped all simply the back opened and removed the battery, then put back to solved the problem.

    I did not really send picture messages since I got my phone, of course I sent normal text messages but just not been sending images to third parties or received no more. Well yesterday my good friend sent me a picture and for me he gets up and shows the message size, and has two buttons indicating the download and the other one that said reject and then he said: the date it will expire. So I clicked on the download button, the text turned gray and says download. So I waited... and waited and waited some more more, but nothing appeared. I thought maybe it was the message, but today at my mother and sister tried to send me picture messages and that they would not open either. He comes to say download I waited thirty minutes for each message today and nothing.

    It upsets me and I don't know what to do or how to fix. There, can someone help me? Give me some information or give me a solution? Should I just go to Verizon to ask them for help? Or y at - it an easy way to solve this problem.

  • I can't solve this problem: "Error loading C:\WINDOWS\awuvomas.dll the specific module is not found." Can help you!

    Original title: cannot find awuvomas.dll

    I can't solve this problem: "Error loading C:\WINDOWS\awuvomas.dll the specific module is not found."  Can help you!

    It is sometimes easy to get rid of the error message by doing something like disable the startup item in msconfig (if you can still find), but I suggest you fix the problem and difficulty not only the symptom of the problem by simply deleting the startup message.
    I would also not recommend you start digging in the registry to try to find the startup item and remove it unless you have a backup of your system or at least a backup of your registry, because there is no 'Cancel' or 'quit without saving changes' option in regedit.  If you make a mistake, that's all.
    These ideas relieve 'rapid' and sometimes risky of the symptom if they not even work at all, but they can't actually solve the problem.  Also, I'd be suspicious of ideas that begin with the words "try."  You don't need to try things, you need to fix things.  You don't need to try ideas that might work, you must do something that will always work all the time.
    Here are the detailed instructions that protect you and solve your problem in the 'right' way.
    There is very little. DLL files that should be loaded from the C:\WINDOWS folder and is not one of them.  If you do not have a good explanation for the name of the file in a Google search, the chances are good that your system is currently or has been infected by malware.
    A "Cannot find...". ', ' Failed to start..., "Could not load..." ». "Might not work... "" Cannot run ""error loading... ". "or"specific module could not be found"message at startup is usually related to the malware that has been configured to run at startup, but the referenced file has been removed after a malware scan, leaving behind him a startup item or the registry entry pointing to a file that does not exist.
    It might be a removal of malicious software or an application not installed.  The entry may have a curious looking name since it was probably generated at random when the malware was installed. If you search your system for the referenced file, you may not find.
    Windows attempts to load this file but cannot locate because the file has been deleted for most probably during an analysis of the malware. However, an orphaned associate of remainders of startup parameter or registry entry and tells Windows to load the file when you start or connection.
    So you should delete the referenced entry Windows stop trying to load or run the file. It may or may not be included in the registry, but you can find it.  Autoruns (see below) you get the elements no matter where it is.

    You must be sure to solve the problem and not just fix the symptom of the problem by simply relieving your message - system is not a fix (there is a difference).

    If you just locate and uncheck the item in msconfig, which disables the element but does not remove the reference to the element of false starting your computer.   The msconfig program is not a Startup Manager, that's a troubleshooting tool.  Disabling things in msconfig to put an end to the messages and think that your problem is solved is short-sighted and leave behind him a sloppy XP configuration.  Just disable the display of a start-up error message should not count as a 'solution' to the problem.
    If you are comfortable editing the registry, you can find and remove the reference directly from there or remove it using a popular third-party tool called Autoruns.  The problem can always be found in the registry well.
    Before making any changes to your registry by hand or with third-party tools, don't forget to first make a backup of the registry
    . There is no cancellation or exit without saving the option in regedit.
    Here is a link to a popular registry backup tool:
    You can also use the Autoruns to find the element of start remains little matter where he's hiding.  Autoruns does not install anything on your computer.  It will display all startup locations where the reference may be then you can turn it off or remove it completely.  Here is the download link for Autoruns:
    Run Autoruns.exe and wait that he at the end of the filling of the list of entries.
    When the Autoruns is finished scanning your system, it will say "Ready" in the lower left corner.  Autoruns can be a little intimidating to first if you have never seen it before because it displays a lot of information.  You are really interested only a few sections.
    The problem is usually to start the system or the user startup entries, then click the connection tab and see if the startup item is there.
    Scroll through the list and look for a boot entry associated files in the error message.
    If you can't find on the connection tab, look in any tab.
    You can also click file, search to search for logon, or any tab for all or part of the name of the element.
    Right-click on the offending entry and choose Remove.  If you are not sure what it is, you can just turn it off, restart and if the problem is resolved and things are functioning normally and everything works fine, then remove the offending entry.  If you don't see it in Autoruns, you may edit the registry and remove the item from your startup folder it.  Autoruns shall display the same information however.
    Given that your system has or has had an infection, follow up with this:
    Perform scans for malware, and then fix any problems:

  • InDesign CS5 will work with MacOS Sierra?

    Has anyone tried to see if InDesign CS5 will work with MacOS Sierra? I have creative cloud and CS5 on my machine, but due to some of the things that I have to work that only work with CS5 to CS6 I have to keep my old software. I hesitate to upgrade to Sierra until I know if InDesign CS5 will work or not.

    If anyone has tested this, I would be recognizing the return flow, thank you.

    It really depends what you do with it, and a large part of the framework has changes in the operating system for how the application is designed to run in. Your workflow can cause problems when the application works for others or you might be able to use it, but keep in mind has more no support for CS5 Adobe or Apple, so do not expect to solve any problems that you can discover.

    How communicate you with a real person who can help set up my Photoshop CS6 license from a computer Windows to a new Mac?

    Hello

    My son has Adobe Photoshop CS6 when he attended a school for dyslexia and disorders on the autism spectrum with software for students in the United Kingdom.

    He has used with success of this edition.

    I have the codes on the box but didn't post here not sure of what?

    He moved to one-sixth of the Collyers in Horsham college and had to buy a new laptop. The College being all Apple we brought a pro IMac.

    He studied art, graphics and media education.

    It is a challenge for a person with an age of 7 years in reading! Spell checking in the Photoshop really helped his presentation work. The IMac has the recognition voice very good text.

    It will be if everything's going to be all right on to art College to study graphics.

    The problem is that he must now get his Photoshop on his new laptop computer and the version that he only works on Windows.

    It is possible to send a new code for the CS6 works on his laptop?

    In the future it will need to Photoshop and Illustrator professionally, but at this level, we cannot justify paying a monthly fee for the latest version.
