Has anyone here used UTM?

I had a sudden yen to play a few of the ancient games I used to play under OS9 and Snow Leopard, so I assumed that on asking Google the question, I'd be proplelled towards Sheepshaver or the like - names I've seen many times in the past, but never dipped my toe.

This time, Google returned "UTM" as an alternative - up front, it looks incredibly simple to use, with the emphasis on "incredibly". Is anyone here familiar with it?

I have SheepShaver running Mac OS 9 emulation on my M1 Mac (it will aso run on Intel Mac of course). But SheepShaver can't emulate Mac OS newer than 9.

I've just recently created an Alpine Linux VM using UTM on my intel Mac and it runs very nicely. You should be able to create OSX VMs using it. Alternatively you could also use the free version of VMware Fusion, Parallels and
VirtualBox. I've got a Mojave VM running using VMware Fusion on my Intel Mac. --

You probably know this but Parallels is subscription based but has a 14 day free trial.

I use it quite a lot for linux VMs and it's really fast and very light
weight. Not used it for any macOS or OS9 emulation

It's pretty nice. I made a one-click download link like this:

utm://downloadVM?url=https://example.com/My-UTM-VM.zip

People can click the link in their browser, and it downloads the VM image
and loads it into UTM and starts it. From experience with a few hundred
users it's a lot smoother than the equivalent setup on Windows using VirtualBox.


UTM uses QEMU under the hood. QEMU is very powerful but getting it to
emulate specific hardware (like older PowerPC needed for OS9) can require
some tweaking of settings. However it seems like that's already been done:

https://appleinsider.com/inside/macos/tips/how-to-run-mac-os-9-on-apple-silicon-using-utm

and so you can just use their pre-built OS images.

For other MacOS versions it looks like somebody has pre-built the configs: https://github.com/adespoton/utmconfigs

but you have to supply your own MacOS installer and do the install in the VM like you would when installing a new hard drive in the Mac.

UTM used to have an option to download a prebuilt Mac OS 9 VM on their
website but it disappeared a while ago. However the AppleInsider article
you referenced looks interesting especially as my SheepShaver setup crashes frequently.

I've also used the links Theo gave; I have MacOS 9.2 and several shades of OSX all running fine. Must give System 7 a go.
Obligatory old fart observation: got to say those old versions look increasingly well-designed in the context of recent Mac OS's.

OS 9.22 up and running via UTM :) Ah, the nostalgia ;-)

Not sure you can do that with UTM? Basilisk II might be best for 7.

You can always have a play with this:

I think it was Jaimie who pointed out that site some years ago.

I'd forgotten about that! Quite an amazing feat. And Oscar the Grouch is there waiting to be installed :)

No, you just zip up the .utm directory (found in ~/Library/somewhere where
UTM puts its saved VMs), put it on a website and make up the link.

What is UTM?
UTM is a security solution that combines multiple security features into
a single platform or device. It is designed to simplify network security management by integrating various protective functions, such as:

Firewall: Filters incoming and outgoing network traffic.
Intrusion Prevention System (IPS): Detects and blocks attacks in real time. Antivirus/Anti-Malware: Protects against malicious software.
VPN Support: Enables secure remote connections.
Content Filtering: Blocks access to unwanted or dangerous websites.
Spam Filtering: Filters out unwanted emails.
Why Use UTM?

Centralized Management: All security functions are controlled through a
single interface.
Cost Efficiency: Reduces the need for multiple standalone security
devices or solutions.
Ease of Maintenance: Updates and configurations can be managed centrally.
UTM solutions are particularly popular among small and medium-sized
businesses (SMBs) because they provide comprehensive security without
requiring complex infrastructure. If you have more specific questions
about UTM or a particular product, let me know!

I eventually got an OS 7.5.3 emulation running via Basilisk II on my
M1 Mac. It's just the basic OS currently but worth having a play with
on those wet, windy winter days when I've nothing better to do!
