We recommend using the NativeDSD Downloader, available here. It will be an easier, smoother process instead of .zip downloads, which can get very large, and fail.
Before you start
You have enough free disk space to complete the download / unzip.
You do not move or unpack the zip file before download is completed.
You have enough FREE disk space on the volume on which you are downloading and decompressing the zip package to.
Unzipping on Windows
For windows user we recommend unzipping the package using a free app called 7 zip. It is available here: http://www.7-zip.org/.
Make sure you have plenty of available free space on the drive where the unpacked files will be saved to.
Unzipping on Mac
If you use a Mac, you will have more luck with decompressing using this free app rather than the Mac’s own Archive utility.
Make sure you have plenty of available free space on the drive where the unpacked files will be saved to.
