Mac – unable to partition the disk during system installation on your MacBook, it could be due to several reasons, including:
File Vault is enabled: If File Vault is enabled on your MacBook Pro, you may not be able to partition the disk during installation. To disable File Vault, you can boot your MacBook Pro into Recovery Mode by holding down Command + R while restarting your computer. Then, open Disk Utility, select the startup disk, and click on the “File Vault” tab to disable it.
Disk errors: If there are errors on the disk, such as bad sectors, the disk may not be able to be partitioned. In this case, you can try repairing the disk using Disk Utility by booting into Recovery Mode and selecting the “First Aid” option.
Insufficient space: If there is not enough free space on the disk to create a new partition, you may not be able to partition the disk during installation. You can try freeing up space on the disk by deleting unnecessary files or transferring them to an external drive.
Partition map is damaged: If the partition map on the disk is damaged, you may not be able to partition the disk during installation. In this case, you can try erasing the disk using Disk Utility by booting into Recovery Mode and selecting the “Erase” option.
If none of the above solutions work, it could be a hardware issue, and you may need to take your MacBook Pro to an authorized Apple repair center for further assistance.
