This implies you'd run more than one Mac Studio in a cluster, and I have a few concerns regarding Mac clustering (as someone who's managed a number of tiny clusters, with various hardware):
1. The power button is in an awkward location, meaning rackmounting them (either 10" or 19" rack) is a bit cumbersome (at best)
2. Thunderbolt is great for peripherals, but as a semi-permanent interconnect, I have worries over the port's physical stability... wish they made a Mac with QSFP :)
3. Cabling will be important, as I've had tons of issues with TB4 and TB5 devices with anything but the most expensive Cable Matters and Apple cables I've tested (and even then...)
4. macOS remote management is not nearly as efficient as Linux, at least if you're using open source / built-in tooling
To that last point, I've been trying to figure out a way to, for example, upgrade to macOS 26.2 from 26.1 remotely, without a GUI, but it looks like you _have_ to use something like Screen Sharing or an IP KVM to log into the UI, to click the right buttons to initiate the upgrade.
Trying "sudo softwareupdate -i -a" will install minor updates, but not full OS upgrades, at least AFAICT.
- eurleif 10mo agoI have no experience with this, but for what it's worth, looks like there's a rack mounting enclosure available which mechanically extends the power switch: https://www.sonnetstore.com/products/rackmac-studio https://www.sonnetstore.com/products/rackmac-studio
- geerlingguy 10mo agoI have something similar from MyElectronics, and it works, but it's a bit expensive, and still imprecise. At least the power button isn't in the back corner underneath!
- wlesieutre 10mo agoFor #2, OWC puts a screw hole above their dock's thunderbolt ports so that you can attach a stabilizer around the cord https://www.owc.com/solutions/thunderbolt-dock https://www.owc.com/solutions/thunderbolt-dock It's a poor imitation of old ports that had screws on the cables, but should help reduce inadvertent port stress. The screw only works with limited devices (ie not the Mac Studio end of the cord) but it can also be adhesive mounted. https://eshop.macsales.com/item/OWC/CLINGON1PK/ https://eshop.macsales.com/item/OWC/CLINGON1PK/
- crote 10mo agoThat screw hole is just the regular locking USB-C variant, is it not? See for example: https://www.startech.com/en-jp/cables/usb31cctlkv50cm https://www.startech.com/en-jp/cables/usb31cctlkv50cm
- wlesieutre 10mo agoLooks like it! Thanks for pointing this out, I had no idea it was a standard. Apparently since 2016 https://www.usb.org/sites/default/files/documents/usb_type-c_locking_connector_specification_rev_1_0_20160309_0.pdf https://www.usb.org/sites/default/files/documents/usb_type-c... So for any permanent Thunderbolt GPU setups, they should really be using this type of cable
- TheJoeMan 10mo agoNow that’s one way to enforce not inserting a USB upside-down.
- timc3 10mo agoIt’s been terrible for years/forever. Even Xserves didn’t really meet the needs of a professional data centre. And it’s got worse as a server OS because it’s not a core focus. Don’t understand why anyone tries to bother - apart from this MLX use case or as a ProRes render farm.
- crote 10mo agoiOS build runner. Good luck developing cross-platform apps without a Mac!
- jeroenhd 10mo agoPractically, just run the macos-inside-kvm-inside-docker command. Not very fast, but you can compile the entire thing outside of the VM, all you need is the final incantations to get Apple's signatures on there. Legally, you probably need a Mac. Or rent access to one, that's probably cheaper.
- colechristensen 10mo agoThere are open source MDM projects, I'm not familiar but https://github.com/micromdm/nanohub https://github.com/micromdm/nanohub might do the job for OS upgrades.
- rsync 10mo ago"... Thunderbolt is great for peripherals, but as a semi-permanent interconnect, I have worries over the port's physical stability ..." Thunderbolt as a server interconnect displeases me aesthetically but my conclusion is the opposite of yours: If the systems are locked into place as servers in a rack the movements and stresses on the cable are much lower than when it is used as a peripheral interconnect for a desktop or laptop, yes ?
- 827a 10mo agoThis is a semi-solved problem e.g. https://www.sonnetstore.com/products/thunderlok-a https://www.sonnetstore.com/products/thunderlok-a Apple’s chassis do not support it. But conceptually that’s not a Thunderbolt problem, it’s an Apple problem. You could probably drill into the Mac Studio chassis to create mount points.
- broretore 10mo agoYou could also epoxy it.
- badc0ffee 10mo ago> To that last point, I've been trying to figure out a way to, for example, upgrade to macOS 26.2 from 26.1 remotely, I think you can do this if you install a MDM profile on the Macs and use some kind of management software like Jamf.
- 827a 10mo agoThey do still sell the Mac Pro in a rack mount configuration. But, it was never updated for M3 Ultra, and feels not long for this world.
- ThomasBb 10mo agoWith MDM solutions you can not only get software update management, but even full LOM for models that support this. There are free and open source MDM out there.
- cromniomancer 10mo agoVNC over SSH tunneling always worked well for me before I had Apple Remote Desktop available, though I don't recall if I ever initiated a connection attempt from anything other than macOS... erase-install can be run non-interactively when the correct arguments are used. I've only ever used it with an MDM in play so YMMV: https://github.com/grahampugh/erase-install https://github.com/grahampugh/erase-install
