Reinstall Mac Os Catalina Without Losing Data

How to access and use the Internet Recovery mode on Mac computers?

Apple computers are well-known as stable devices with good performance and hardware specifications. The Mac operating system also includes various self-diagnosis and repair tools. Bear in mind, however, that these features might be susceptible to failure. When built-in tools or software-based solutions do not work, the last and most efficient solution is to reinstall the operating system. All modern Mac computers contain two separate methods to reinstall the operating system (by 'reinstall', we mean installation of a fresh OS X version). You can choose to install the operating system from a startup disk or via Internet Recovery.

  • If you had not backed up, you’re your Mac with Time Machine before upgrading to Mac OS Big sur; you can still downgrade to Mac Catalina. The other option is using the bootable installer to reinstall Catalina. Go to the Apple App Store and download Catalina. Follow this procedure to install Catalina using the bootable Catalina.
  • To reinstall macOS, including the latest Big Sur, Catalina, Mojave, without losing data, you can follow the professional guide to update the OS, which will not cause data loss in most of the case. If you still have worries, back up your Mac in advance or recover the lost files with EaseUS Data.
  • Reinstall a previous version of the Mac OS using the appropriate Mac OS Installer. Use Time Machine to restore from a date when your Mac was using a previous version of the o perating system. With any of the downgrade methods, you’re going to lose all the data currently on your Mac.

In this article, we describe the second method: Internet Recovery to install the operating system version that came with the version of your computer. If your computer was released with OS X Mavericks, using Internet Recovery will install this particular version, while reinstallation from the recovery partition will result in a fresh version of the current operating system. Therefore, if you perform the reinstallation process via the Recovery utility, you will receive the same operating system version that existed prior to reinstallation. The Internet Recovery method is useful if you wish to downgrade the operating system. A big advantage of this method is the ability to bring back the computer to full functionality when software is corrupted. Note, however, that stable internet access is required to perform the reinstallation process via Internet Recovery. An unstable Internet connection can lead to the process crashing and no access to the computer. Therefore, you are advised to use an Ethernet network, rather than Wi-Fi. In this article, we walk through the entire Internet Recovery method.

Step 4: Reinstall Mac OS X without Losing Data. When you get the macOS utility window on the screen, you can just click on the 'Reinstall macOS' option to proceed. Afterward, you simply need to follow this basic drill to reinstall macOS on your system. A confirmation message will appear, informing you about the reinstallation details.

Requirements to access Internet Recovery Mode

Ensure that the Mac meets the minimum requirements to access Internet Recovery mode. All compatible computers are listed below. Bear in mind that some earlier versions of Apple devices might also use this feature. Apple state that Firmware updates grant access to Internet Recovery mode. If your device is older than the machines listed below, check the Apple firmware updates list here.

  • MacBook Pro (13-inch, Early 2011)
  • MacBook Pro (15-inch, Early 2011)
  • MacBook Pro (17-inch, Early 2011)
  • iMac (21.5-inch, Mid 2011)
  • iMac (27-inch, Mid 2011)
  • MacBook (13-inch, Mid 2010)
  • MacBook Pro (13-inch, Mid 2010)
  • Mac mini (Mid 2010)
  • MacBook Pro (15-inch and 17-inch, Mid 2010)
  • iMac (21.5-inch and 27-inch, Mid 2010)
  • MacBook Air (11-inch and 13-inch, Late 2010)

If you wish to reinstall the Mac operating system, your network must use DHCP and WPA/WPA security methods. All authentication methods listed below are incompatible with macOS installation via Internet Recovery. If your network uses one of the methods listed, change the setting to a compatible configuration (at least for the purpose of the installation process).

  • WEP
  • WPA-Enterprise
  • Certificate-based authentication / 802.1x
  • Proxies (where specific proxy servers must be configured in network preferences)
  • Captive Wi-Fi networks (where you click an “Agree” button to access the Internet)
  • PPPoE (where there is no router handling the PPPoE connection)

Reinstall operating system by using Internet Recovery mode

When you are sure that the Mac is able to access Internet Recovery mode, there is another important task before installing the fresh operating system version. After a successful reinstallation process, the computer will contain only the default software (which is delivered with macOS). All personal data and applications that you have manually applied to the hard disk will be erased. To protect your personal data, create a backup with Time Machine or similar software. Finally, when you are ready to reinstall the operating system, click the Apple logo in the menu bar at top of the screen and select Restart or Shut Down. Once the system starts booting and you hear the startup chime, hold down the combination of Command, Option (Alt), and R.

Keep holding these keys until the animated globe appears with the message below stating 'Starting Internet Recovery' and 'This may take a while'. Note: If you are using a Mac laptop, use the built-in keyboard to access Internet Recovery Mode, since keystrokes might not register properly on external keyboards.

Next, select the Wi-Fi network. If you are not using an Ethernet network, click the drop-down menu and select the desired network. You must confirm access to a Wi-Fi network by entering the password. Then press Return on the keyboard or click the checkmark symbol on the screen to continue.

After successful authentication to achieve the network connection, the Mac will begin to download a recovery system image from Apple's servers. You will see a progress bar monitoring the status of the download. Depending on your internet connection, this process may take some time. Ensure that the computer is connected to the power adapter.

When the image is downloaded, the OS Utilities window will pop-up, giving access to the usual features, such as Restore from Time Machine Backup, Reinstall OS X, Get help online, and Disk Utility. From this point, the process will be similar to the reinstallation via recovery partition. Detailed information about how to install the macOS can be found in this article.

A very small price to pay to be able to reinstall Mac OS without losing data at any time. How to recover any Mac files quickly You might not think about it right now, but it’s likely that at some points you’re going to lose some of your files.

Macs are generally known for being very dependable machines that produce little bugs, have a secure sandboxed space to fight off any intrusions (especially so since macOS 10.15 Catalina), and usually present minimum problems for the whole duration of their ownership.

However, occasionally, Macs do allow clashing processes to result in bugs, accumulate too much cache files from resource-intensive apps, and even let in a rare piece of malware if you’ve given it your admin access credentials (please don’t do it).

So there might be a time when you think that your Mac is not the same as it used to be and you probably want to queue a Mac reinstall OS process to start anew. To do that, you need to launch the Mac Recovery Mode.

What’s Mac Recovery Mode?

Chances are you might’ve never even used your Recovery Mode Mac feature before. So what is it?

Mac Os Apps On Windows

Recovery Mode is an essential part of macOS utilities and lets you get out of precarious situations when your Mac is seriously stuck or some process is invading your system so much that regular Mac restarting doesn’t seem to help. A thing to do then is to boot Mac in Recovery Mode, which only allows for a few core features to operate.

In such system restore Mac environment, you’re able to:

  1. Restore from Time Machine backup

  2. Reinstall macOS

  3. Get help online (browse Apple’s documentation)

  4. Disk Utility (repair or erase your hard drive)

The natural thing to try and do if you see that your Mac is not working as expected is to go ahead and reinstall OS X. But before you proceed with the Mac system restore process, let’s see if you can fix your Mac using more accessible tools.

How to optimize your Mac the easy way

You can think about the Mac reinstall OS procedure as some heavy artillery you have at your disposal but that’s reserved for true emergencies. For most situations — Mac slowing down, files piling up, and apps spreading leftovers — a good Mac optimization software should be more than enough.

How To Restore Mac Os Without Losing Apps Windows 10

  1. To speed up your Mac, head to the Maintenance tab under Speed

  2. Select Free Up RAM, Run Maintenance Scripts, Speed Up Mail, Reindex Spotlight, and anything else you find interesting

  3. Click Run

How to boot Mac in Recovery Mode

In some rare circumstances, your Mac might become seriously unresponsive, in which case you need to know how to reinstall Mac OS X to pretty much return all system processes back to their default settings.

Best Mac Os Apps

Another important time to do a Mac reinstall OS is when you’re planning to sell your Mac and want to wipe out all your data completely or perhaps you’ve bought a Mac with someone else’s stuff on it.

In both situations, the process for going into the Recovery Mode Mac feature is the same:

Reinstall Mac Os Catalina Without Losing Data Connection

  1. Turn off your Mac and start it back up while holding ⌘ + R

  2. The Recovery Mode Mac menu will open. You can then choose the appropriate course of action. If you experience some systemic problems, you can just choose to reinstall macOS. If you have a Time Machine backup available, choose that. If you’re about to sell your Mac, use Disk Utility to erase your hard drive first and then start your Mac with ⌘ + R again and reinstall OS X. Click here to know more about how to use time machine on mac.

  3. Click Continue and follow the directions for the chosen option

How to install another version of macOS

When it comes to using the system restore Mac functionality, most of the time you’d just reinstall macOS you’ve had before. A lesser known trick is to use Mac Recovery Mode to install an older (or in fact the newer) version of the operating system.

Data

So while you use ⌘ + R to go into Recovery Mode for the same macOS, you can use Option + ⌘ + R instead to install the latest compatible macOS or Shift + Option + ⌘ + R for the possibility to get the original macOS that your Mac was shipped with or the oldest available version after that.

Why would you ever need to run an old operating system? Mostly because you might find that some software you depend on is not yet compatible with the latest version of macOS.

How to connect to WiFi in Recovery Mode

Before you go into the Mac system restore environment, it’s good to check that your WiFi is stable and fast or, better yet, connect to a wired connection via Ethernet.

Still, if your WiFi has broken down for one reason or another while you’re in Mac Recovery Mode, there’s a way out:

Reinstall Mac Os Catalina Without Losing Data
  1. Find and click the WiFi icon in the menu bar

  2. Select a WiFi network

  3. Enter the password if needed and press Return

How to properly backup your Mac

Talking about your Mac malfunctioning and all the important macOS utilities that help you with its recovery, it’s impossible to skip the notion of conducting frequent backups — the only thing that stands between your sanity and losing all of your files in an accident. But backups are boring and not something most people would want to bother themselves with, so automation is key.

Get Backup Pro is the most flexible solution for keeping your files safe, regardless of what happens with your Mac. It offers you easy ways to synchronize your Mac with another device, to clone your hard drive to an external one, to establish a scheduled versioned backup routine, and even to do frequent incremental backups of the most important files. Even better, you can mix and match, and create multiple clones of the same files or break up your hard drive in different ways for extra security. A very small price to pay to be able to reinstall Mac OS without losing data at any time.

How to recover any Mac files quickly

You might not think about it right now, but it’s likely that at some points you’re going to lose some of your files. Maybe it’s because you’ve overwritten changes on the same document, you’ve accidentally deleted an important file, or your Mac just simply crashed. A robust backup solution would be your first go-to, but what do you do if you need the last version of the document that hasn’t yet been saved anywhere?

Disk Drill is an essential Mac recovery app that can quickly scan your affected hard drive and extract all the recently deleted information in seconds:

Reinstall Mac Os Catalina Without Losing Data
  1. Open Disk Drill and wait for it to display all the connected drives

  2. Click Recover next to the hard drive with deleted files and follow the guide

Note: Even though Disk Drill is able to recover old files in most circumstances, it shouldn’t replace your comprehensive backup strategy. Think of Disk Drill as an uber-important tool of last resort.
