Hello, yesterday Apple released macOS 10.13.4: I still have to upgrade, meanwhile I wonder if the slow boot issue on Macbook with SSD has been solved. My MacBook Pro 13" with SSD 850 EVO stops at about 75 % of startup launch bar, waits for 10-15 seconds, then keeps back booting. This with 10.13.3. How about this new update? Bye!
