macOS installer won't accept my password

The answer to the question is that the password error prompt may be caused by keyboard layout, case recognition, or installer source. The macOS installation interface uses an American English keyboard by default. The input of non-English keyboards may not match. It is recommended to switch layouts or avoid special characters; the password is case-sensitive, and it is recommended to check the CapsLock status or try all lowercase; if the installer comes from another Mac, you need to enter the Mac password to make the installer; you can also try to re-download the installer through recovery mode, confirm the administrator account identity, or format the disk with disk tools first.

How to partition hard drive for Windows installation

Partitioning is crucial to installing the system. Good partitioning can improve the system operation efficiency and data management convenience. First of all, you need to know that there are up to 4 main partitions, and logical partitions are required if there are more than UEFI. The new computer recommends that the GPT format be started with UEFI, and the old machine uses MBR; the system disk is reserved at least 60GB. It is recommended that home or office users be divided into 2 to 3 zones: system disk (60 to 100GB for disk C), data disk (remaining space for disk D), optional backup/tool ??disk (approximately 50GB for disk E), dual systems require additional partitions. During installation, operate the partition on the "Custom Installation" page, and be careful to delete the old system partition to avoid confusion. In terms of details, the default NTFS format is maintained, the SSD is turned on AHCI mode, partition first and then install the system, and disk management can be used to adjust the partition size but avoid it.
