I upgraded to MacOS Sierra recently, since then, my Mac Mini needs to strat befor 5 times actually implemented, why?

Mac Mini (mid-2011), 2.5 GHz mid-range Core i5, 16 GB 1600 MHz DDR3, 256 GB Solid State Drive Storage

10.12 MacOS

I upgraded to MacOS Sierra recently, since then, my Mac Mini must start 5 times before it actually starts.

It starts and restarts in the middle of the boot process, 4 times.

Why?

I have experienced a similar curiosity, but often with messing around on a Linux partition. I do not have a definitive answer for you, but check on this thread (MacBook Pro will restart several times during the boot process) and maybe here further (oots http://apple.stackexchange.com/questions/88213/how-to-find-cause-of-repeated-reb)

I hope this helps!

  • after upgrade to macOS sierra cannot connect to citrix receiver apps

    I use Citrix receiver apps to make my day to day work. The same citrix apps are also accessible via a web browser (Safari) and everything worked fine until the version IE Capitan.

    After upgrade to macOS sierra I can't you connect/launch of citrix apps. I tried with receiver and citrix via web browser as well, but its not connecting.

    Is anyone else facing the same issue or know the fix.

    Earlier, I thought that maybe some problem of connectivity, but after a lot of troubleshooting it still did not work and shows the same error "failed to initialize." (attached image).

    Then clicked on suddenly to mind that I just upgraded my MacBook OS. In order to confirm if his new problem of macOS or anything else, I have installed Windows 10 on vmware fusion and tried to connect to citrix receiver and it worked only! without any operation of additional troubleshooting, it is confirmed that the issue is again macOS.

    So as a temporary workaround, you can use virtual windows OS on top of the operating system Mac OS page sierra to launch citrix applications.

    But apple needs to fix in the Sierra.

    This seems to be, in part, a browser problem.

    Have you tried, since El Capitan or Sierra, another browser?

    And it would move from Citrix to make their applications compatible with OSX.

  • Impossible to upgrade usb macos sierra

    Hello!

    Created a USB Sierra installer in accordance with the old guide: create a bootable OS x - Apple support Installer

    The command used is:

    sudo /Applications/Install\ macOS\ Sierra.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume --applicationpath /Applications/Install\ macOS\ Sierra.app 

    USB is supposed to be successfully created, and I get the icon 'Install macOS Sierra' on the desktop after inserting/editing of the USB. I then open it and run the Setup program, it tells me it takes about 6 minutes, and then it tells me to restart in the sierra of macOS. After the reboot, I'm still on El Capitan!

    What I am doing wrong? I would like to install from USB to avoid having to download each of my Macs! It would be very unhelpful in my time and my bandwidth!

    As soon as it restarts, try to select the installer from USB as a boot using Boot Manager device - an Option button and selecting this device.

    Please read an external USB (Mac Intel) - storage device from Apple Support.

  • Upgrade to MACos Sierra now all my 'saved' go to the wrong folders

    I was wondering if someone else has upgraded to the beta version of MacOS Sierra. Now, when I save a file, it goes in the wrong folder.

    For example if I have a folder with the 6 files in there:

    Folder 1

    Folder 2

    Folder 3

    Folder 4

    Folder 5

    Folder 6

    And I chose to save it in the folder 4. When I go into the folder 4 it isn't here, but if I look in other files, he sometimes recorded on file 2, sometimes 6 file is in the right area, just in the right folder.

    Anyone experience anything like this?

    better to demote, still beta beta

  • Photos edited in Photos App is missing after upgrade to MacOS Sierra

    After updating to Mac OS Sierra, all my versions published of my photos is missing.

    Updated to:

    MacOS (10.12) Sierra

    App photos (Version 2.0 (445.1.15))

    It is said:

    -Update of El Capitan Sierra.

    -When the update, I started App Photos and update the library (260 GB).

    -A took the Photos App in the meantime round.

    -After all the thumbnails update was missing, but the pictures would be accessible by clicking on them.

    -Photos App must rebuild now all the thumbnails, but the photos I edited is still missing and even can not be seen by clicking on it (like the non-edited).

    -The missing files are a .jpeg and raw (.nef) from Nikon files.

    Have you tried:

    -Existing photo editing works

    -Edit photos (previous edition) missing persons, sometimes shows the missing picture, but it is not always a new tile.

    Any suggestions of how to make the pictures to update modified pictures?

    Did you turn on your mac to remove duplicates or similar cleaning applications?  Some cleaning tools are not safe to use.

    How do you change the photo in question? She has been published with adjustments to Photos or have you used an extension of photo editing?

    -Edit photos (previous edition) missing persons, sometimes shows the missing picture, but it is not always a new tile.

    Have you tried to take pictures with missing tiles to the original version in the control panel?

    And pictures can be exported from Photos or you get an error message?

  • MacOS Sierra runs smoothly in my mac?

    Hey everybody,

    I use a MacBook Pro (15-inch, mid-2012) with the following configuration:

    RAM: 4 GB 1600 MHz DDR3

    Intel HD Graphics 4000 1536 MB

    The latest version of the OS will work in a smooth way, or it may cause some problems and be slow? :/

    It should be good. You may consider upgrading the RAM, but if you run not usually intensive tasks on your Mac 4 GB should be OK.

  • Question of WebGL on macOS Sierra

    I upgraded to macOs Sierra and since then, I've noticed a degradation in performance of Webgl.

    I have a 13-inch early 2015 rMBP and any program I write (or open on the internet) is able to go beyond 40 fps.

    I don't know if it affects OpenGL too... Am I the only one that has this problem?

    I have this problem as well. I also have a 2015 13 "Macbook Pro and I can use is more TinkerCad, because it's useless now."

    This should probably be posted in the Group of Sierra of macOS.

  • update problems since macOS Sierra to iMovie

    Hi everyone, I hope someone can help me out here because I'm starting to get really frustrated.

    I have a MacBook Pro and yesterday I upgraded to macOS Sierra and I regret it now because when I wanted to work with iMovie today he is more worked how it used to. I make youTube videos for a living and I'm already a day behind my schedule download because of this problem. Basically what is happening, it's only when I imported my video files to my SD card into iMovie files seemed normal, however when I put them in a project and began to play them I noticed that the color was distant, it almost looks like there is a misty overlay. At first I thought that maybe my DSLR camera has broken out and checked the files on the SD card (played files to QuickTime) but they seem quite normal and how they should look, iMovie for a reason any turns them... I have no idea how to solve this problem, because I'm not even sure what really is the problem. Can someone help me please?

    Hi, Anny,

    I don't know what is happening with the change of color in your timeline.   Whenever there is an upgrade of the operating system there always is the possibility of conflicts with specific applications until the bugs have been worked.  So, it is possible that your question is related to your recent update to OS Sierra - hard to say.  I'm not aware of anyone who still displays with your problem.

    Given that the problem appears only in your timeline, maybe media are complex and your computer is hard to deal with in the time line or keep in touch with your editing.

    You can see if the problem is linked project by creating a new project with the same or different media.   Is it possible to have a color filter activated inadvertently?  You can also try to reopen iMovie while maintaining the option and command keys and selecting Remove preferences.  Sometimes, it allows to launch iMovie in a different account, as your guest account, in which case there is a conflict with your current user account.  If none of the works above, you can try to create a new library on your boot drive or disk formatted Apple iMovie and see if your projects are working properly.   Another possibility is to restore your old operating system from Time Machine.

    In any case, I think that once the film is shared out he will play with his normal colors.  Try sharing file on your desktop to confirm that.   If he plays well, at least you'll be able to keep your schedule download then you want to solve your problem.

    Best,

    Rich
