Liquid Glass is pretty much the talk of the town regarding WWDC 2025 and with good reason. That’s not the only thing Apple announced at WWDC though and I think one of the more interesting pieces is their new containerization framework (written in Swift).
Docker for Mac has historically (and I would say currently but it’s getting better) had subpar performance especially when dealing with the filesystem. One of the reasons for this is that Docker for Mac runs a lightweight Linux virtual machine using tools like Hyperkit (past) and Apple’s Virtualization Framework (current) and this layer of indirection introduces several layers of overhead.
Docker has been working to improve the performance on Mac such as acquiring Mutagen, introducing VirtioFS, and using Apple’s Virtualization Framework on Apple Silicon. All of these things have moved the needle but the underlying challenge remains: Docker on macOS is essentially Docker-on-Linux-in-a-VM.
If Apple’s new containerization framework solves these issues then it’s going to be a very welcome change for anyone that run containers on a daily basis.
For more information Apple has a video on their developer site.
