Run Mac data recovery in macOS recovery mode with Internet
If your Mac is connected stably to the Internet, use the method below to run Mac data recovery in macOS recovery mode.
Step 1: Start your Mac into Internet Recovery mode.
If your Mac was introduced before 2018:
- Turn on your Mac by pressing the power button.
- Hold down the "Option+Command+R" keys immediately until you see the spinning globe on the screen.
You will see the spinning globe instead of the Apple logo because here you're starting macOS Recovery mode via the Internet.
If it is a T2-secured Mac (introduced in 2018 and later):
- Turn on your Mac.
- Press and hold the "Option+Command+R+Shift" key together until the spinning globe appears, which boots your Mac into macOS recovery mode.
For Apple Silicon M1, M2, M3 & M4 Macs:
- Press and hold the power switch (Touch ID) until you see Loading startup options.
- Click “Options” to enter macOS Recovery Mode.
The appearance of the "macOS Utilities" menu indicates that your Mac is in macOS Recovery Mode.
Tips: In the macOS Utilities > Reinstall macOS, you can see which operating system is installed in the Recovery Mode.
Step 2: Connect your Mac to the Internet.
Step 3: Open "Terminal" from the “Utilities” drop-down menu. 
Step 4: Run the following command to launch iBoysoft Data Recovery for Mac:
sh <(curl boot.iboysoft.com/boot.sh)
If you want to recover data from a Fusion Drive, run the command below:
sh <(curl http://boot.iboysoft.com/fdboot.sh)
Step 5: Wait a moment to launch iBoysoft Data Recovery for Mac in macOS Recovery mode.
Step 6: After this tool is launched, select the Macintosh HD (or macOS) volume and click "Search for Lost Data." If you see there is a Macintosh HD-Data (or macOS - Data) volume, please select this one. 
Note: If you lost data from the Fusion drive, which is split to SSD and HDD, please select "Fusion drive" from the left side of iBoysoft Data Recovery for Mac.
Step 7: After your data is found, preview the files and see if they are recoverable. 
Step 8: Connect an external storage device to your Mac.
Step 9: Tap on the "Recover" button and select the external storage device to store the recovered files.
Here are some tips that may be helpful:
- There are two spaces in the above command, one space after sh, another space after curl.
- If you see a message "No such file or directory" after running the above command, it means you entered the wrong command; enter the correct one and try again.
- If you see a message "Could not resolve host: boot.iboysoft.com" after running the command above, it means your Mac has not connected to the Internet. Please connect your Mac to the Internet and try again.
