How to install macOS Mojave from scratch

Today has definitely been the day that macOS users have our new OS for Macs. After seeing how the rest of the systems of Apple products were updated a week ago, iOS, watchOS and tvOS, Today it's finally up to us Mac users.

Finally we have here the new version and it is the day of doubts about the installation on our Mac. Doubts and questions for various reasons: Will it work well on my Mac? Will everything install ok? Do I install over or remove everything and start from scratch? In short, a good handful of doubts that are common and that obviously have a different answer for each case.

The first thing is to see the compatibility of the new system with our Mac

While the Mac to be compatible with the new macOS Mojave Do not have a single doubt to update. This is something that does not even arise when our team has the possibility of updating, it is always the best option, we will be more secure against third-party threats and we will receive system news. So first I will advise on compatibility and then do not hesitate, update.

Backup

We know that we are heavy with this but the most important thing once we are clear that our Mac is compatible with macOS Mojave, is to make a backup. Either with Time Machine or directly with an external disk the most important thing now is to have a "backup" of the system, so don't forget and hit it.

Upgrade or install from scratch?

Apple has been managing system updates well for years and we can say that it is no longer so important to update our Mac from scratch. Although it is true that every time we change the system and not the number (macOS Sierra, macOS High Sierra, macOS Mojave) we can install from scratch for our peace of mind. I repeat, this is no longer so important today and it is more due to the desire you have to do this installation from scratch than to eliminate bugs or problems from previous versions.

My personal recommendation if you have time and possibility is that you install from scratch in each new version, but I already say that this it's more of a personal habit than a "you have to do it" yes or yes. The current macOS are similar systems and therefore it is no longer necessary to carry out this installation from scratch on our Mac since system changes are usually minimal. Of course, if we have not carried out an update from scratch for many years, we can do it, which is not so complicated.

We can use two ways to perform the clean installation, through Terminal or through Diskmaker X, in this case what we are going to do is from Terminal. In both we need an external USB or an SD card of at least 8GB, In the case that it is a USB stick, keep in mind that it is of quality is important to carry out this process. Nothing happens if it is an advertising USB or similar, although it is always better to have a good USB for these cases.
