In the Apple environment, the concept of resizing containers is typically associated with managing disk partitions. Disk Utility, a built-in macOS application, allows users to resize, add, or remove partitions on their drives. This is important for users who need to allocate more or less space to different partitions without losing data. This article will guide you through the process of resizing disk partitions on macOS using Disk Utility.

Examples:

1. Resizing a Partition Using Disk Utility GUI:

   • Open Disk Utility: You can find Disk Utility in the Applications > Utilities folder or by searching for it using Spotlight (Cmd + Space and type "Disk Utility").
   • Select the Drive: In the Disk Utility sidebar, select the drive that contains the partition you want to resize.
   • Partition Tab: Click on the "Partition" button in the toolbar.
   • Adjust the Partition Size: In the pie chart that appears, click on the partition you want to resize. Drag the resize handle to increase or decrease the partition size. Alternatively, you can enter a specific size in the "Size" field.
   • Apply Changes: Click the "Apply" button to resize the partition. Disk Utility will process the changes, which may take some time depending on the size of the partition and the amount of data.

2. Resizing a Partition Using Terminal:

   • Open Terminal: You can find Terminal in the Applications > Utilities folder or by searching for it using Spotlight (Cmd + Space and type "Terminal").
   • List Partitions: Use the diskutil list command to list all the partitions and identify the one you want to resize.

     diskutil list

   • Resize the Partition: Use the diskutil resizeVolume command followed by the identifier of the partition and the new size.

     diskutil resizeVolume disk0s2 200GB

     Replace disk0s2 with the correct identifier for your partition and 200GB with the desired size.

   • Verify Changes: After resizing, you can use the diskutil list command again to verify that the partition has been resized correctly.
