Can't free up space for Sierra install

After downloading mac os Sierra, I started to install it. I forgot to check my disk space. now I'm stuck in this message:

Mac OS could not be installed on your computer - there is not enough free space on - to install.

I tried to go into safe mode. no luck just a white screen. tried to erase some files in the terminal it says that it is read-only. tried to change the permissions chmod 777. no change. I don't know what to do.

Hi Hzmajin,

Thank you for downloading Mac OS Sierra! I understand that you are now stuck in the installation due to a lack of disk space on your Mac. Great way to try to start in safe mode to resolve. Given that it did not work, I start up your Mac in recovery then try a reinstall of the OS X earlier if possible. If you made a back up with Time Machine, you can restore the Mac since this backup or you can use to clear the drive completely and then reinstall OS X. After you upgrade to Mac OS Sierra, you can then manually restore your data from the backup of your Mac. If you do not create a back up before you tried to upgrade and archive and reinstall does not work, try using target disk Mode to access the disk drive on the Mac and remove the unwanted data in this way. The links below will help you with the suggestions I provided.

How to reinstall OS X

OS X can be installed on the same version or an earlier version of Mac OS X, without deleting your data. You don't need to remove or disable the existing system first.
Boot to OS X Recovery now command-r immediately after start-up or you restart your Mac. Release the keys when you see the Apple logo. Start-up is finished when you see the OS X Utilities window.

If you do not want to wipe your drive before reinstalling OS X, open utility disk from window OS X Utilities, and then use disk utility to erase the drive. Quit disk utility when done.
Erase the disc is not necessary unless you transfer your Mac to a new owner, the partitioning of your drive for use with Boot Camp, or attempt to solve the problem as disk utility cannot repair.

Choose to reinstall OS X OS X Utilities window, and then follow the instructions on the screen.
This installs the latest version of Mac OS X, which has already been installed on your Mac.

Restore from a backup

If you have a Time Machine backup of your Mac, you can restore this backup the OS X. This erases the disk you restore, then replace everything on this disc with OS X and other data from the backup. To continue, OS X Recovery starting, then choose restore from the backup Time Machine and follow the instructions on the screen.

Share files between two computers with target disk mode

These steps should help you in obtaining Mac OS Sierra installed on your Mac with success. Please use the Apple Support communities to post your question. Have a great day.

  • How can I free up space on my C drive without dumping files I need to power my computer? Windows XP 2002

    How can I free up space on my C drive without dumping files I need to power my computer? I have currently 40,4 GB used and I don't know how or what is out there that I don't need? I have a backup of system restore that takes a lot of space, but Im saying that I can not remove it by a pop-up box that says access denied even though I have since transferred it on my external backup hard drive. Can someone please help? Thank you

  • Can't free up space from Oracle

    Oracle version:
    Platform: Solaris

    In the bdump directory, I saw some big files with name like this < SID >arc1< PID > .trc. I tried to free up space by running cat/dev/null >
    .TRCarc1< PID > < SID >, but it seems the files are not narrowed. Can someone tell me how can I free up space in these files without having to restart the database?

    Thank you

    On Unix, when someone delete a file if the file is always written by some processes, space occupied by the file is not released. This is because the file is always opened by the process and the counting of this file is different from zero.

    For free space, you may have to let the process close the file explicitly or kill the offending process.

    Hi Billy,

    Try a clean boot (Vista and W7) If the problem goes away then it's just a matter of tracking down the culprit at the origin of the problem. Follow the procedures described in the article. Once found, remove, delete, disable or uninstall. Once don't forget to reset your system back to the normal state, as described in the procedures. If the problem occurs in clean mode then just restore the system to normal and reboot - this solution will not work. If you are using XP, see and

  • I ran out of free space on the hard drive how can I free up space

    My pc is freezing or locking up when I run a desktop wallpaper animated, so I defragment a saw that I was up to 20% freespace

    You can create more free space in C in carrying one of the measures suggested below.

    The default allocation for the restoration of the system is 12% on your C partition is more generous. I have them would be reduced by 700 MB. Make my computer right click on your icon, and select System Restore. Place the cursor on your C drive select settings but this time find the slider and drag it to the left until it shows 700 MB and output. When you get to the settings screen, click on apply and OK and leave.

    A flaw that might be useless which is for temporary internet files, especially if you keep no copies on the disk offline. Setting the default value is 3% of the walk. Depending on your attitude to copies offline, you could bring it to 1% or 2%. In Internet Explorer, select Tools, Internet Options, general, temporary Internet files, settings to make the change. At the same time, look at the number of days, the story stands.

    The default allocation for the basket is 10% of the disk. Change to 5%, which should be enough. In Windows Explorer hover over your Recycle Bin, right click and select Properties, Global and move the slider from 10% to 5%. However, try to let you become so complete that if it is complete and you delete a file by mistake it will bypass the Recycle Bin and have gone forever.

    If your drive is formatted as NTFS another potential gain arises with your operating system on your C drive. In the Windows directory of your C partition you will some uninstall files in your Windows folder in general: $NtServicePackUninstall$ and $NtUninstallKB282010$ etc. These files can be compressed or not compressed. If compressed text the name of the folder appears in blue. If these files are not compressed you can compress. Right-click on each folder and select Properties, general, advanced, and check the box before you compress contents to save disk space. On the general tab, you can see the winning amount by deducting the size on disk size. File compression is only an option on an NTFS formatted disk partition / partition.

    Select Start, all programs, accessories, System Tools, cleaning disk to emptying your trash, delete temporary Internet files and other selected options. I recommend also you click Other Options, System Restore and delete all but the last system restore point. Run Disk Defragmenter.

    Using the system restore option is most appropriate when your system is slow and you need to increase the free disk space on your C partition. If you have errors that could be solved by using the system restore to your system settings back to before the error occurred initially do not use this option.

    If more than one person uses the computer and they have their own user log you need to run Disk Cleanup in each user profile that you want to delete all the unwanted files.

    A better program of disk cleanup is cCleaner. Delete System Restore points may be important if you have little free disk space. The ability to delete them is one of the tools options. You can selectively remove those created in less important moments.

    cCleaner comes with a registry tool. Do not use this tool as any registry cleaner could lead to the creation of very difficult to resolve system errors.

    Hi Luis Sarubbi,.

    The recovery drive is there for one purpose and that is to store the recovery image. You shouldn't have anything else on this drive other than the recovery files. As the space for the recovery disks is relatevely small the only way to free up a space is to move the files to another drive or deleting files. Why is it necessary that you free up space on this drive? Unless you know exactly the name of the recovery of all files, you might end up deleting or moving something that is necessary for recovery. If you end up doing it any subsequent recovery may fail.

    Unless there is a specific reason for needing to free up space on this drive, for example, you have been storing document on disk files, then I season you quit well.

    I'm having a problem using top too much disk space on my (vista) C drive on my satellite L500, now that I've filled with iTunes music files. I want to use a part of the E drive to 'Add' on the C drive space. Is this possible?

    1 delete all the files and unnecessary programs from the disk: C to the freed space.
    2. move all the movies, photos, music on the disk E;
    3. If you use the Download Manager to download files, you can change the path where to save the downloaded files in your local case: E

    You can change the size of the partition in administrative tools in Control Panel. However, I prefer to use a partition manager paragon to resize partitions on my computers. Before add/create partitions, make sure that you have made a recovery disk.
