If your macbook acting up and you think reinstalling macOS might help, don't worry about losing your stuff. Here's a simple guide to reinstalling macOS without saying goodbye to your data.

If your computer’s acting up and you’re thinking about reinstalling macOS to fix things, you’re not alone. Many people worry about losing their data and the hassle of starting over. The good news is, you can actually reinstall your macOS without losing any of your stuff. It’s a quick process that can help with everything from minor glitches to major slowdowns. If this sounds like what you need, just follow the steps below to get your Mac back on track.
What’s macOS Recovery, and how does it do its thing?
macOS Recovery is like a handy helper tucked inside your Mac’s system. It’s there to assist when your Mac is acting up, especially if it won’t start up normally. The cool thing is, macOS Recovery has its own little space on your computer, away from the main operating system. This means it can still do its job even if your regular OS is having a bit of a meltdown.
In macOS Recovery, you’ve got a couple of useful tools, like one for restoring from Time Machine and another for managing your disks called Disk Utility. But the real gem we’re focusing on is the OS reinstallation tool. This nifty tool allows you to reinstall your macOS version and get all the latest updates, and the best part is, it won’t wipe out your data. So, if you’re dealing with OS-level issues, this tool can be a game-changer without the stress of losing your files.
WARNING – Reinstalling macOS without losing your data is a good trick, but it’s not foolproof. Whenever there’s a system update or upgrade, there’s a chance you might lose some data. So, if you can, it’s smart to make a backup before you go ahead and reinstall macOS. But we get it – if your macOS is not booting up at all, making a backup might not be doable.
