How To Do Clean Install Of Mac Os
Nearly Windows users reinstall their operating arrangement at some indicate, but this isn't as common a step for Mac users. While at that place are less invasive ways to make an old Mac feel like new, reinstalling macOS tin can prove useful in some cases.
Whether you're having a major problem and want to start fresh, or plan to sell your Mac and need to reset it, reinstalling macOS is a relatively painless process. We'll walk you through it.
Note: I performed this process using a mid-2012 MacBook Pro running Os X 10.seven Lion and ended with macOS Loftier Sierra. The process may look slightly different on your machine.
Before You lot Starting time: Back Up!
Presumably, you've used this estimator for some time and have personal information on information technology. Reinstalling macOS will wipe everything on your system, then it'southward vital that you support starting time. Before y'all back up, you lot might desire to gratuitous up space past getting rid of old files y'all never use.
The easiest manner to support is using Apple's built-in solution, Fourth dimension Machine. We've covered how to utilize Time Machine to back up your Mac; you'll need an external hard drive to take reward of it.
If you lot don't want to apply Time Machine or don't have an external hard drive, you tin can look at alternate Mac fill-in solution. Some of these offering cloud backup, and then you lot won't need any extra storage handy. However, cloud backups almost always require a paid subscription.
If you lot only accept a small amount of files, you lot might wait at syncing your most important files to Google Drive or other cloud storage. Another alternative is copying your vital folders to a USB flash drive.
Whatever you cull to do, remember that this process will erase everything on your Mac.
Sign Out of Apps

Sign out of iTunes by opening it and choosing Business relationship > Sign Out. Yous tin sign out of iMessage by opening Messages and choosing Messages > Preferences. Cull your account on the left sidebar and choose Sign Out.
Finally, sign out of iCloud by visiting System Preferences > iCloud and choosing Sign Out.

In the old days, you could reinstall the OS through the DVD that shipped with your Mac. But since new Macs don't have an optical bulldoze, we'll apply the built-in Recovery Way to exercise so. This volition work on any Mac running Os X 10.7 Panthera leo or later.
Close downward your Mac. Concur the Cmd + R keys (ane of many Mac startup key combinations) and plough the power back on. Continue holding these keys until you see the Apple logo. After a moment, you'll encounter a macOS Utilities (or Os Ten Utilities) folio with several options.
If this doesn't work (possibly your computer freezes at the Apple logo as mine did), yous'll need to start the internet Recovery manner instead. This runs the recovery environs from the internet instead of a partition on your difficult drive. Concord Cmd + Option + R at startup to access this. You'll see a spinning globe instead of the Apple logo.
Connect to a Wi-Fi network if you're not already. Then wait a chip while your computer downloads the recovery environment. You'll need to select your linguistic communication to enter Recovery fashion proper.
When using internet Recovery mode, the system may reinstall a dissimilar version of macOS than you were using. Mine installed Mavericks, even though I was running Lion to start with.

To properly reinstall the Os, you'll showtime need to erase the deejay. To practice this, select Disk Utility from the menu.
Next, select your internal hard drive (normally labeled Macintosh Hd) from the left sidebar. Switch to the Erase tab on the right side. Make sure the Format is set to Mac Os Extended (Journaled). The default name of Macintosh HD is fine, unless you lot prefer something else.
Click Erase and confirm the operation. In one case it's done, you're ready for a fresh install of macOS. Press Cmd + Q to quit the Disk Utility.
Step 3: Reinstalling macOS
Back on the macOS Utilities menu, choose Reinstall macOS (or Reinstall OS X). Click Continue to continue; Apple will verify your computer'due south eligibility to install the OS. You may see a prompt to enter your Apple tree ID every bit part of this process.
Accept the license understanding, then click your difficult bulldoze to select information technology for installation. Click Install to commencement the procedure. Depending on your reckoner's specs (and internet connection speed if using net recovery), this will have some time.
In one case you meet the Welcome screen, your Mac is back to manufactory defaults. If you're selling or giving away your Mac, you tin can press Cmd + Q at this point. You lot'll get a prompt to shut downward your Mac; the adjacent owner tin proceed with setup later on.

Next, ostend your keyboard layout and striking Continue once again. You'll then need to connect to a wireless network (you can skip this for at present if needed).
Continuing on, y'all'll see the Transfer Data to This Mac screen. Here you can select From a Mac, Time Motorcar backup, or startup disk to import the information you lot backed up earlier. Choose Don't transfer any data now to skip this; you can become through the process later.
Your Mac volition then prompt you to sign in with your Apple ID.

If you want to use a local account, choose Don't sign in. Yet, this will prevent you from using the App Store, FaceTime, and like.
Accept the terms and weather, then create your computer business relationship if you didn't sign in with an Apple ID. From here, give your computer a moment to set, and you'll be greeted with your desktop.
