The only issue I've experienced with VMware Fusion Pro is that it doesn't register correctly with the main macOS system, causing repeated notifications about background installations. This is a minor inconvenience.

VMware Fusion is good, especially for the graphical user interface. However, it would be beneficial to have a more developed command line interface to deploy solutions. This would allow scripting for launching specific Virtual Machines. Additionally, enhancing the API interactions could improve the ability to manage VS and deploy various kinds of guests.

Fusion is not meant to be scalable as it runs on desktops and laptops. For scalability, ESXi is the right solution.

The solution is quite heavy in terms of resources like RAM and CPU. They should minimize the number of resources. Also, the installation process could be simpler for end users to understand. 

They should make it compatible with Windows and Linux. Presently, it works well only with Mac systems. In addition, they should enhance essential security features.

VMware Fusion's licensing cost needs improvement.

I would like to see newer and updated cloud functions.

The way they handle snapshotting can be improved. One time, I moved a machine from one to another, and I tried to pull it up on the second machine, but it didn't work. This was because I had not cleaned up the snapshot before I deleted it and moved it across. So, when I tried to pull it up, it wouldn't let me bring it up. 

The backups for the VMs themselves can also be improved. I pretty much have to rely on Windows backups and not something on VMware. That's where it needs improvement.

I am able to upload from my Fusion into the ESXi easily. I'm able to spin something up on Fusion and push it into the big arena, but the reverse is not as easy, that is, trying to pull something down from that. I would love to have a functionality where I could pull something from the VMware infrastructure into Fusion, but I'm not sure if I can take something from ESXi and pull it into Fusion. 

The solution could be a little more stable.
