Don't lose your files. Here's how to regularly back up or restore your Mac using Apple's handy, built-in Time Machine tool.
t’s a good idea to periodically back up your computer. You want to make sure your documents, photos, and files are protected in case of hardware failure, software glitch, or malware attack. Apple makes this process easy for Mac users with the built-in Time Machine tool that lets you back up your entire system and then restore individual files or the entire drive.
You can trigger manual backups or set them to run automatically. Backups can be stored on an external drive, another Mac, network storage, or an AirPort Time Capsule. Time Machine has not changed in years, so the process is the same no matter which version of macOS you’re running. The initial steps differ based on your backup media, so we’ll cover each type separately.
In the case of an external drive, plug it into your Mac and make sure its icon appears on the desktop. Open System Preferences and go to Time Machine > Select Backup Disk, then select the drive and click Use Disk.
If the disk isn't formatted to support the Mac and Time Machine, you’re asked to erase the disk first. The drive is then prepared for backup.
To use another Mac as your backup destination, you’ll need to create a shared folder on it to serve as the backup location. Apple can walk you through the steps. You then connect the two computers by opening Finder on the Mac you wish to back up and double-clicking the destination Mac listed under Network.
Enter the username and password for the destination Mac and click Connect. You should then see the shared folders on that Mac, including the backup folder you set up.
Open the Time Machine preferences on the Mac you want to back up. Click Select Disk, then choose the backup share on the destination Mac and click Use Disk. You’re then asked by Time Machine to enter the username and password for your destination Mac.
Backing up to a network attached storage device (NAS) can be tricky because Time Machine works only with certain volume types. If you own a Synology NAS, Synology supports Time Machine and provides a support page on how to use your NAS for backups. For other types of NAS drives and network storage, you may have to contact the vendor to find out if and how it can be used for Time Machine backups.
If you’re able to use your network storage, open the Time Machine preferences on the Mac you want to back up. Click Select Disk and choose the backup share on your NAS or other network device. You’re then asked by Time Machine to enter the username and password for your network share.
By default, the backups are set to run automatically. Time Machine keeps local backups based on available disk space, hourly backups for 24 hours, daily backups for a month, and weekly backups for all the past months. The oldest backups start to get deleted as you run out of space on your backup media.
If you don’t want the backups to run automatically, uncheck the option for Back Up Automatically. You can also check the box next to Show Time Machine in menu bar for quicker access.
To view and control more settings, click the Options button. Here, you can choose any partitions that you don’t want to include in the backup and decide whether or not your Mac should be backed up when on battery power.
To perform a manual backup, click the Time Machine’s menu bar icon and select Back Up Now, or hold Ctrl and the icon for your backup drive and select Back Up Now. Your system is then backed up in the background.
Now if you click the Time Machine icon in the menu bar, you can see the progress of the backup. Keep in mind that a backup run over a network will take much longer than a backup to a connected drive. You can stop the backup by selecting Skip This Backup. A notification will appear on the screen when the backup is completed.
Restore Individual Files
To restore an individual file or multiple files from a backup, click the Time Machine icon in the menu bar and select Enter Time Machine. Several cascading windows pop up, with each window pointing to a different backup. Notice the two arrows to the right of the windows with a label that says Today (Now). This indicates the folder is the most recent version.
Click the up arrow to go back in time to find a previous backup that has the files you need. Once you find the correct backup, select the folder with the files you wish to restore, then click the Restore button. The files are then restored to their original location.
Restore Your Entire System
To restore your entire system from a backup, connect your Time Machine backup disk to your Mac. If the backup is on a network share, make sure your Mac is on the same network. You’ll then need to reinstall macOS as part of the factory reset process.
Once the operating system is reinstalled, you can then transfer your existing data using the Migration Assistant. Choose From a Mac, Time Machine backup, or Startup disk from and click Continue.
You then select your Time Machine backup media and click Continue. Confirm the information to transfer, deselecting any content you don’t want restored, then click Continue. Create a password for your account and click Continue.
The information from your backup is then transferred and restored. You will see that the migration is complete. Click Done, sign back into your Mac, and finish the setup.

Does your Chrome browser feel like it's running a bit slower than usual? These tips and tricks can help you give Google Chrome a speed boost
Check Your Internet Speed
Before you blame Chrome for your slowdowns, make sure your internet connection is up to snuff. Run a speed test like to see how your connection measures up. It's possible you're just experiencing a slowdown in your area, or you're on a crappy public network. (Or maybe you just need to pay for faster internet.)
Update to the Latest Version of Chrome
Each new version of Chrome contains new features, security fixes, and—often—performance improvements, so it's possible updating to the latest version may help your speed woes. Even if it doesn't, it'll keep you safer from online threats.
Chrome updates itself automatically, so chances are you're already on the latest version, provided you've closed the browser recently. If you're behind, Chrome will display a yellow or red arrow in the upper right-hand corner of the browser.
This means an update is waiting for you, so all you have to do is close out the browser window or click the arrow and choose Update Google Chrome to restart and get the update. It probably won't make any night-and-day speed differences, but it's a good place to start nonetheless.
Run a Malware Scan
Before you go digging into Chrome's settings, you might want to ensure you don't have any malware on your system. Run a scan with your anti-malware tool of choice and make sure there aren't any nefarious actors running in the background. These can shove extra advertisements into the pages you visit or track your behavior, which require resources—and thus can slow down your browser and computer.
Run the Chrome Cleanup Tool
Google developed a program called the Chrome Cleanup Tool, which would detect potentially unwanted programs (PUPs), like toolbars and other automatically installed extensions that your antivirus may not be designed to catch.
Google has since integrated this directly into Chrome, and you can run it by going to Settings > Advanced > Reset and clean up > Clean up computer. Run the tool and it'll check your computer for any software that might be slowing down your browser.
Uninstall Extensions You Don't Need
One of the best things you can do to speed up Chrome is slim it down. Extensions and tabs are the biggest resource hogs, and the fewer you have, the snappier Chrome will feel.
Let’s start with extensions: you can see which ones are taking up the most CPU and RAM by pressing Shift + Esc on your keyboard, which will bring up Chrome's Task Manager. Check out which ones are hogging the most resources, and which ones aren't crucial to your workflow.
Uninstall extensions by right-clicking on their icon in the toolbar and selecting Remove from Chrome. Or go to chrome://extensions and remove them from there. The more you get rid of, the more of a speed boost you'll get (not to mention a security boost, since extensions can be hacked or sold to adware companies).
Close (or Unload) Tabs You Aren't Using
If you're the kind of person who opens 19 tabs and leaves them running for later, it's a good bet your slowdown is coming from having so many sites open in the background. Chrome can discard tabs if it runs out of memory, but in my experience, it isn't very aggressive about it.
Close any tabs you don't need (once again, Shift + Esc is your friend), and bookmark them for later. You can also grab an extension like Auto Tab Discard, which allows you to automate the "unloading" of certain tabs based on different criteria and keep them in your tab bar, which you can then reload as you need them.
Yes, I realize the irony of installing an extension when we just told you to uninstall as many as possible, but depending on how many tabs you tend to keep open, the result may still be a net positive speed increase for this particular case.
Wipe the Slate Clean
If you still can't get Chrome to cooperate, it may be time to go nuclear and reset the browser to its original defaults—no extensions, custom search engines, or other saved settings. This can be a pain, but if you discover Chrome goes back to being zippy after resetting, you might be able to keep it tidier and prevent it from building up extra cruft (or at least determine which extension or settings caused things to slow down later).
To perform a reset, head to Settings > Advanced > Reset and clean up > Restore settings to their original defaults > Reset settings. Of course, it may not be Chrome's fault at all—your computer may just be getting a little long in the tooth.
