How To Reinstall macOS On ANY Mac

Hey folks today , I'm going to teach you how to reinstall the operating system on your Mac .

That's coming up next on Tech Talk America .

Hey folks and welcome to the class .

There are a few different ways that you can reinstall the operating system on your Mac .

The good news is it's really easy , but the best method for you depends on your set up .

All the different methods that we're gonna be going over today will safely reinstall the operating system so that your data is preserved .

Now , that being said , it's always a good idea to have a backup before proceeding and keep in mind reinstalling the operating system won't help if your Mac is experiencing hardware failure .

So here's how this video is gonna work .

You remember those adventure books when you were a kid ?

Well , this video is about to feel like one in a moment .

I'm gonna describe four types of Mac setups .

Then you're going to fast forward to the time code that I'll flash on the screen you ready .

Let's begin .

If you're on any type of Mac laptop with an Intel chip , skip ahead to that time code .

If you own an Intel based imac Mac mini or Mac Pro and you do not have a way to plug your keyboard into your Mac .

Skip ahead to that time code if you own an Intel based imac Mac mini or Mac Pro with a wired keyboard or if you have a wireless keyboard that you are able to plug into your computer .

And by that , I'm referring to the one that comes with some of the more recent models , which you'll see pictured here .

Skip ahead once again to that time code .

If you own any Mac with apple silicon , skip ahead to that time code .

Hey , group one .

The first thing you need to do is shut down your Mac .

After it's completely powered off , you're gonna press and release the power button and then immediately hold down one of the three following combinations of keys .

If you hold down command and the R key that will reinstall the latest version of Mac Os that is presently installed on your computer .

Now , please note that does not mean it's up to date .

It's just the same version that you've been running .

If you hold down option command and the R key that will upgrade your Mac to the latest version of Mac Os .

If you hold down shift option command , R that will reinstall the operating system that originally came with your Mac or the closest version that's still available .

If you're not sure which of those three to go with my recommendation is that you go with good old command R .

Now , you'll need to hold those two keys down until you see the apple logo with a progress bar .

At this point , you may be asked to enter in the administrator password to your computer and then you'll be brought here to the utility screen .

Now , just follow the prompts and you're good to go .

The reinstallation process takes somewhere around an hour depending on what type of Mac you're using .

Hey , group two .

How are you ?

No way to plug your keyboard into your Mac .

No problem .

You've got two options .

Now , forgive me , I can't completely simulate this first solution because it only works on older operating systems .

So I'm going to show you part of this and I'll verbalize the last couple of steps .

If you go to the Apple icon at the top left , then go into system preferences , then you can click on start up disc .

You'll notice on my screen .

It only says Macintosh HD .

But on yours , you may see a second partition that contains the installer , select that partition and click restart .

It basically walks you through the entire rest of the installation .

If you're on a map that is running an older operating system , I'll include a link in the video description to this page on Apple support's website .

From here .

You'll find links where you can download older operating systems dating all the way back to Yosemite heads up .

If you live outside of the US , you'll need to scroll down to the bottom and change the region to your country before clicking those links .

Once the operating system is downloaded , it automatically launches and walks you through the entire installation process .

If you own one of the newer macs that comes with one of the apple silicon chips , including M one or M two , here's how you can reinstall the operating system first , you'll need to shut down your computer .

Then after it's totally turned off , you'll need to press and hold the power button .

Don't let go until you see this screen where it'll show you Macintosh HD and options , select options and press continue .

You should now get an Apple logo with a progress bar and after a moment or two , you'll see the Mac Os utility screen .

Click on reinstall Mac Os , follow the prompts and you're good to go .

Thank you so much for watching everyone .
