Summary of current problems encountered when starting the Mac mini external hard drive

For some preparations for those who want to use external hard drives, welcome to add. 1. As long as the read and write speed of the external hard disk increases by 3000/s, it will not affect Apple Intelligence 2. When the external hard disk is booted, the kernel extension cannot be rebuilt correctly, and software that requires kernel extension such as Paragon NTFS cannot be used. 3. If you use an external multi-disk 3.5-inch hard disk box with 10Gbps usb3.2, as long as there is a system hibernation, the hard disk box will follow the hibernation function. You cannot use TimeMachine to back up after turning off the monitor, because the Mac will also perform TimeMachine backup, and if the hard disk box is also hibernated at this time, an error will be reported, prompting: Time Machine has not completed the backup because some files are unavailable. The backup will continue after the Mac is unlocked. The solution is ` sudo pmset-a sleep 0 ` to turn off Mac hibernation. If you use a 5Gbps usb3.1 hard disk box that sleeps for 10-15 minutes without access, it will have no impact.
