  Parallels Desktop 18 liberates M-series chips, measured how much faster it is on Mac Studio   Unknowingly, it is the season of the annual Parallels Desktop release. This time, Parallels, as usual, launched the latest version of Parallels Desktop 18 before the official release of the new macOS 13 Ventura. Many people may have similar questions: Parallels Desktop (hereinafter referred to as PD) releases a new version every year and then needs to re-purchase or subscribe. Is it necessary? In fact, the answer to this question is not difficult. In addition to adding new features that year, PD will be optimized for the latest version of macOS to be launched every year (for example, macOS 13 Ventura in 2022). So you can first see if this version of PD has new features to attract you to buy, or if you want PD to be optimized for the latest version of macOS you use, and then make a decision. In addition, according to my experience, usually after a single purchase of PD, there will be no problem in executing across the next generation of macOS. For example, PD 17 can theoretically run normally on macOS 13 Ventura, and this year’s latest PD 18 should also theoretically run on macOS 14 in the future, but there will be no way to support new features. Of course, the limitation of CPU and RAM does not mean that if you use PD, it will always only use up to 4 CPUs and 8GB RAM. This limitation is the upper limit set in "each virtual machine". For example, if you have an 8-core CPU and use the standard version of PD to open 2 virtual machines at a time, although each virtual machine can only have 4 vCPUs, PD will automatically balance the load of the two virtual machines on all 8 physical cores. In addition, the small print at the bottom reads: "Up to 62GB of RAM and 18 CPUs on Apple with M-series chips." That is to say, even if you have the current top Mac Studio M1 Ultra 128GB RAM, you cannot allocate all 128 GB of memory to the virtual machine, the maximum is 62GB for a virtual machine.
