If you have complaints like “I updated my Mac and lost everything” or “Mac update deleted everything”, the best possible solution is to get things back from Time Machine backup.
Time Machine is a backup utility built-in to macOS, allowing you to back up your entire Mac. As a result, it’s possible to easily recover documents, apps, music, photos and other data missing after Mac update. Below are two facts.
Step 1. From the Apple menu, select System Preferences, and then choose the Time Machine icon. Select the Show Time Machine in menu bar checkbox.
Step 2. Choose Enter Time Machine from the Time Machine menu. You'll be taken to the Time Machine window. Then you can navigate to the file or folder you'd like to restore.
Step 3. Select a file and press Space Bar to preview the file. Find the one you need to recover and click Restore to restore the selected file, or Control-click the file for other options. Time Machine will copy that file back to its original location on your hard disk.
Tip: You can also use the timeline on the edge of the screen to see the files in your Time Machine backup as they were at that date and time and use the onscreen up and down arrows to jump to the last time the contents of the window changed.
With the macOS update, some people lost a part (or worse, all) of their photos. Also, users of iPhoto find that the iPhoto app itself along with the photos has gone. With both cases, it’s very likely that the photos are still there, safe and sound, and you just need to make them reappear again. If so, there is an easy fix, which doesn’t require backup or any third-party tool.
Before getting started, let’s talk a little bit about iPhoto. Despite being discontinued for years, iPhoto is still available for use after the year of 2015 when it was replaced with Photos app. It can still run on Mojave. However, with the release of macOS 10.15, it’s not usable anymore. That’s the reason why users lost the iPhoto app after upgrading to Big Sur.
The solution is easy. Switch to Photos and load your iPhoto library.
Step 1. Launch the Photos app while holding down the option key, which will bring up the Choose Library window.
Step 2. Select iPhoto Library. Click Choose Library.
The app will start preparing Library. Once the process is completed, you will be able to see the lost photos again. It’s that easy to retrieve lost photos after Mac Big Sur or Catalina update.
