On September 20, the Mac world went from OS X to macOS Sierra, presumably the first in a new line of operating system versions from Apple Inc. It’s been exactly a week since macOS Sierra was released to the public as a stable version, so it’s time to look back and see what went well and why some macOS Sierra users are clamoring to get back their beloved OS X Yosemite and El Capitan. The first set of issues is with the installation itself. Users have been facing multiple issues including installer download errors, authentication problems, WiFi slowing down, app errors, errors with some Logitech mice and so on. We’ve listed the top 3 problems here and outlined what you need to do to fix those problems quickly, without that dreaded trip to the Apple Store.

One final note before we dip into the issues: Sierra is undoubtedly superior to any version of OS X, and most users can seamlessly move to Sierra without problems. These issues listed below may be restricted to a few users, but it should help make the transition easier. #1 macOS Sierra Problem – Sierra Won’t Download This error comes in mainly two forms – a download error or an ‘already downloaded’ error.

If you’re getting a download error such as “Failed to Download” or “An Error has Occurred”, or it shows the status as “Downloaded”, that means either the macOS Sierra installer failed to download correctly, or you have downloaded a previous version of Sierra such as the beta version or the GM build that were released prior to September 20. In both cases, you’ll need to find a file called “Install macOS Sierra” and delete it. Once you’ve done that you can repeat the download process on the App Store and it should download just fine. Do check your WiFi connection to see if it’s stable because intermittent or weak signals tend to affect downloads. In some cases files may get corrupted in the process as well. The safest thing is to delete the installer and download it again.
