At the end of October, Apple presented new Macs with an M4 chip. In addition to the MacBook Pro, the Mac mini and the iMac have been updated by the Apple brand. All three computers havethe new M4 chip, already seen at the start of the year on the iPad Pro.
Although the performance of these Macs is no longer in doubt, they nevertheless encounter a major problem. It actually seems impossible to launch a virtual machine with an old version of macOS on your computers. The problem was noted by Csaba Fitzl, a computer science researcher. Since then, numerous testimonies have come to confirm his version of the facts.
Every time a user tries to launch a virtual machine using a version earlier than Ventura 13.4, the ordinary encounters a problem and displays a black screen.A problem that seems to only affect Macs equipped with an M4 chip.The use of virtual machines (VM) was possible on other Apple brand devices.
A fix in sight?
Although using a VM on a Mac is not a classic use of your computer, this practice is nevertheless quite widespread. The issue affecting M4 Macs appears to affect the kernel boot process, the point at which the virtual machine initializes its virtual core. The activity monitor spots a vulnerability at this time.
According to computer researchers who looked into the problem, Apple could fix this bug by releasing new IPSW files. A practice far from common at Apple. Given the number of people who usevirtual machines, the Apple brand could keep this bug without offering solutions.
As great as they are, these new machines should therefore be avoided if you use VMs on a daily basis. As a reminder, the new Mac M4s have been available for sale since the beginning of November. The Mac mini M4 starts at €699. It costs €1499 for the iMac M4 and €1899 for the MacBook Pro.
