Sierra of loading

I tried to update Sierra on my mac pro book, but I don't have enough memory. I have returned to the old operating system and have cleaned memory. But now, I don't know how to re install Sierra. Can anyone help?

I'll assume that by 'memory' you mean disk space rather than the amount of RAM you have. Also, I'll assume that you have downloaded the installer of Sierra, but he refused to run because there was not enough disk space to install on.

If this is all true, the installation program, called 'Install macOS Sierra' should be in your Applications folder. Find it and double-click it to start the installation process. But you might want to do a full backup first in case you need to return to your current installation.

On the other hand, if your upgrade was successful, but then had trouble running (explaining the reversion), the Setup program has been deleted automatically, you will need to download from the App Store again. You can find in the section "purchases".

  • Down the new OS Sierra of loading

    I am trying to download the new Sierra... download tell me it will take more than 24 hours to download.  Is this typical?  Modernization of the previous system has taken a few hours... but more than 24?   Just curious.

    No, this is not typical. Should be approximately 30 to 40 minutes on a broadband connection high speed.

    If installed, disable the anti-virus software, and then try again.

    Hello gregor gregor gregor.

    Thank you for using communities of Apple Support. It's my understanding you are needing help with upgrading to Sierra, as the Mac App Store gives more the possibility to download. I want to assure you that you can upgrade and enjoy Sierra successfully.

    If you quit the Installer do not click on continue, you can open it later in your Applications, Launchpad or Spotlight folder. Looking for a file named Install macOS Sierra. During the installation, your Mac may restart several times. It performs then a few initial configuration in the background tasks. Although these tasks are ongoing activities such as the use of Spotlight or Mail may not seem as fast as they were before.

  • On macOS Sierra - Parallels Desktop 12 - error unable to load Parallels driver - error ID 352

    I have updated at 10.12 some weeks ago, with no problems.

    I used 10 Parallels and put Windows 7 access every day. My Mac software was 100% up-to-date.

    After a few weeks, I started Windows and Parallels showed the error "Failed to load the driver" and KB Parallels, I found that I may need to upgrade. As I was planning to upgrade anyway, I upgraded to Parallels 12 and got the same error.

    I contacted Parallels support - they responded with this:

    Failed to load Parallels driver. Problem ID: 352

    Cause

    The problem is in the bundle /System/Library/Extensions/IOPCIFamily.kext from Apple. In the bundle's info.plist is damaged due to some reasons.

    Resolution

    If please contact Apple Support team and send them system.log and corrupt /System/Library/Extensions/IOPCIFamily.kext/Info.plist.

    The person wrote that if Apple can't help, we will try to help "."

    Is anyone able to help please?

    Thank you.

    It is a user to user forum, not a team of Apple Support forum. In any event, it sounds like a problem of Parallels as it is unlikely that multiple versions of the operating system have defective or damaged kernel extensions.

    For what it's worth, I use Parallels 11 without problem on macOS Sierra to access Windows 2000, Windows XP, Windows XP64, Windows 7 and Windows 10 of virtual machines. I think you should go back to parallels Support. I've avoided Parallels 12 because of all the problems users are reporting

  • Sierra and Photos: unable to load library of pictures located on a NAS

    I have a 300 GB photo library located on a NAS.

  • Installation of macOS Sierra results in the error message "load installer has no signature verification.

    I tried to recreate the USB key with a new download installer.

    The first Apple support guy that I talked to said to make a recovery of the internet. The problem here is tries to install El Capitan, but never finished. The countdown reaches 0, then goes up to about 30 minutes back. It just keeps doing hours and hours.

    The second Apple support guy that I talked to said to do a regular restore (CMD + R), but it always goes to the recovery of the internet. I'm guessing that there is no restore partition.

    The computer has 10 Windows installed on a Bootcamp partition, and that seems to work very well. I can't installed macOS.

  • USB disabled after the update of the Sierra (a short circuit and a work)

    Hi, when I bought my mbp 13 inches mid2012 (used, not new) I noticed that a USB port did not work. In the Yosemite sometimes I noticed that a USB port consumed too much energy and have been disabled. (I think because the usb port has been short-circuited. Year when it was time to update the mbp to El Capitan I had a few panic the kernel and the newspaper was shown as the last driver loaded the USB driver, so I kept the mbp with Yosemite. A few days ago, I updated for Sierra but only usb which used to work stopped working. It has enabled and turned on but Finder and disk utility does not see the drive. In an Apple dealer they said that could be established relationships with some oxide and next week will take it and see what the problem is.

    If there is someone with the same problems, please tell me what to do! I don't want to put in the trash my mac just for a flash drive... but I need!

  • iMovie crashes after Sierra upgraded.

    I have a MacBook Air and yesterday I upgraded the OS to Sierra. After that, iMovie crashes as soon as it load and continued to do so throughout the day. I can't access a video of work I had done and really need to send it to my client to download on their website. I repeatedly sent reports to Apple and restarted my laptop 3 times. I can't force leave them, because the program is still not open long enough to do something.

    I also tried to get a fix to remedy the situation, but there doesn't seem to be available.

    Does anyone have a solution to this? My laptop is less than 3 years.

    Hi nybor99,

    I understand that you updated your MacBook Air to macOS Sierra and now the iMove application is not responding.

    You did it to Time Machine backup your computer before updating?  You install iMovie version 10.1.2 after update to macOS Sierra?  Have you restarted your computer?  You try to access a project in iMovie or did you finish the project and export a video file (film)?

    Try these initial steps to solve your problem:

    1 launch the App Store on your Mac app, click updates, and then click the button next to iMovie update.

    2. restart your Macbook Air.

    3. open the Finder.  Open the Applications folder.

    4. right click on iMovie and choose read information.   Check the version 10.1.2.

    5 double-click on the iMovie application to open it.

    If the problem persists please reply to this thread with an update, including error messages that you may encounter and we will study further with you.

    Take care.

  • After the installation of Sierra, calendar does not work

    After installation of Sierra, when you open the calendar on my Mac, missing entries and the screen is frozen with the comment 'Moving calendars to the server account.' I signed that I the cloud to see if it would help, but I still have this problem.

    Hello and welcome to Apple support communities, Stanley Star.

    If I understand your message to the right, at the opening of the calendars for the first time after upgrading to Mac OS Sierra, you are missing calendar events and the app is frozen with a message saying "moving to Server account schedules. Calendars, this is one of my apps used on my Mac, so I certainly understand the importance of having the opening and operating as usual. I'm happy to help you to turn it on again!

    Icloud and a signature was an excellent step to try. Here are the steps I recommend to do next:

    1. Check that the date and time are correct in your Mac by following the steps in macOS Sierra: set the date and time on your Mac.
    2. Close the present calendars on your Mac. If you are also reminders, close that as well as reminders and schedules work together. If the calendars close normally, will not force close it by clicking the  in the upper left corner of your screen, select force to close, select the calendars in the list of open applications, and then click the button close Force.
    3. Go to System Preferences > iCloud and uncheck the boxes next to the calendars and reminders.
    4. Restart your Mac.
    5. A times restarted, open again your calendar application, select "Calendar" in the Apple menu bar in the left corner of your screen, select "Add an account", choose iCloud and sign in with your Apple and the password.
    6. Give your calendar some time to sync and charge all your data. Once it is loaded successfully, and you can see all your events, open the reminders and do the same steps for signing in iCloud there are also well.

    Thank you for using communities of Apple Support.

    Take care.
