Delete Mac Partition without deleting data

How to remove a Mac partition without losing data ? Mac users search for this question whenever they need to merge data of two or more volumes. Me too have experienced this situation and fortunately, got a working solution for the issue.

In my Mac, there were three volumes – Macintosh HD, Patition A and Partition B. Usually , when there was anly one volume, it was smooth but, after creating multiple partitions its performance started lagging. Now, it was very risky to go back and reduce the number of partitions.

There was a risk of losing valuable data while deleting a partition in simple way. So, I decided to first move my important data from Partition B to A and then remove Partition B.

Fig1. explains the exact situation.

Macintosh HD Size: 200 GB Free Space: 100 GB

Partition A Size: 150 GB Free Space: 10 GB

Partition B Size: 150 GB Free Space: 100 GB

I wanted to move 50GB of data to partition B there was no enough free space to to hold new data. Now, resizing was the task to accomplish first. I used Stellar Partition Manager to resize my Mac volume.

It offers options to Add, Format, Delete, Hide and Reveal a Mac partition. The GUI is much easier to understand and use than that of Disk Utility. I simple dragged the partition A towards B and its done.

Macintosh HD Size: 200 GB Free Space: 100 GB

Partition A Size: 210 GB Free Space: 70 GB

Partition B Size: 90 GB Free Space: 40 GB

Just copied all my content from Partition B to A and deleted the Partition B. Here is the pic.

Partition A Size: 210 GB Free Space: 70 GB

Free Space: 90 GB

The next task was to merge the free space of 90 GB to Partition A to create a single volume. I did it with Stellar Partition Manager by expanding its size.

Finally, I deleted Mac volume without deleting data in it. For details and more features of this Mac partitioning software visit Mac Partition.
