Assuming your startup is successful and you are using OpenCore, you can avoid "verbose" booting (that display) by opening your config.plist in PlistEdit Pro (for instance) and then selecting "NVRAM/Add/7C436110-AB2A-4BBB-A880-FE41995C9F82" and looking at "boot-args." In the "Value" column, delete "-v" and save your config.plist. Again, if your system is successfully booting, you can delete "keepsyms=1" also, and just leave the "boot-args" string value blank.
(Of course, if your boot process was hanging at that point, you will just lose the information on your screen, and your system will still not boot.)
