I am already upgraded to macOS Sierra from scratch, do I install a Time Machine backup?

This is another one of those questions that we tend to answer quite frequently once a new version of Apple's operating system is released and the answer to it is usually quite simple. The truth is that sometimes I personally have installed an Apple operating system from scratch and then loaded the backup that the user had made so as not to have to enter everything manually and so on, but it is advisable since we have performed a clean installation on the Mac is that everything we install is from scratch and manually so as not to drag the failures of the previous backup.

And the main reason to perform a clean installation is to leave the system as if our Mac had come out of the same box With which Apple gave it to us and little by little we have been adding programs and applications that are necessary to us on a day-to-day basis and more.

That is why the recommendation in this question is that we only directly transfer the iCloud data of contacts and the backup copies of those documents that do not directly affect the operation of the Mac, so it is important to put aside the backup and especially considering that at this point the installation in general has been a success.

On the other hand, and as I said at the beginning of this article, if we install the backup made before the clean installation, nothing happens and it can be done without problems, but we will drag the errors and possible garbage that we have since the last time we performed an installation clean and this is not what we are looking for with this type of updates from scratch, We are looking to start with a new Mac and spending a little time to carry out the task is infinitely better.
