Today we will tell you how to roll back from a new APFS file system to HFS + on a MacBook or iMac.
Apple for years used the Mac file system HFS + in Mac, and until recently it was used in iOS. However, it was recently replaced by the new APFS system. This is a modern file system developed for modern memory drives, therefore some of the disadvantages of HFS + in it have been eliminated.
But everything is not so smooth. APFS is still incompatible with FileVault 2 or Time Machine. Because of this, some users would prefer to return to the HFS + system. You can do this if you have the skills to work in the Terminal program. We will describe all the necessary commands for this purpose below. If you are careful, then you will succeed.
How to roll back from APFS to HFS +
Step 1: Open Terminal on the Mac whose file system you want to roll back.
Step 2: Run the following command - diskutil list . The Apple _ APFS list of the GUID section appears. You will need to write down the partition ID. As an example, we use "disk2s0".
Step 3: After that, you will need to delete the partition and all its contents. Introduce the command carefully.
diskutil apfs deleteContainer / dev / disk2s0
Note: If an error occurs, simply start over from the first step.
Step 4: Again, run the command below and make sure that the partition is now called Apple_HFS.

Step 5: Finish with the following command:
diskutil eraseDisk JHFS + Untitled / dev / disk2s0
Now you must have an empty HFS + file system!
