I probably can (although I purchased audio hardware I've purchased specifically because Firewire is dead on the new Macs). What would I be waiting for though? Are we expecting a great leap forward with the M5?
If I were you, I’d buy a base Mac Mini M4, and spend the next 6 months learning Linux.
Multi-Core utilisation of all music apps is pitiful at present, and the blame-game is currently in full swing.
M3 Ultra Studio owners complaining of performance spikes at 27% utilisation. Windows even worse.
Then, if you’ve bought UAD hardware, you’ve got another can of ugly worms with Mac OS - with yet another blame-game going on.
To be honest, this is the worst year to buy a computer for music, ever. Not that any year is good for UAD in my opinion!
You haven’t cited your musical preferences. If it’s orchestral, then RAM is needed - lots of it.
If not, then single-core performance is crucial. A base M4 Mini will do 117 tracks of audio, with a 24-bit full Drumkit, and multitudes of plugins.
The M5 might be 4.6Ghz over the M4’s 4.46Ghz. You’ll hardly notice. But RAM speeds, RAM frequencies, RAM bandwidth, and Neural Engines are going to be increased on the newer M5. This you will notice, if you require thousands of Orchestral samples loaded in, and fired from RAM. At that point, external Thunderbolt speeds become moot, as 7GB/sec is a drop in the ocean, compared to a full 24-bit Concert Orchestra firing out of RAM with ambient stereo-mic placements, and a 120dB dynamic-range - with a 72-piece choir, and 72 instances of Antares Autotune!!
The M4 Max 16-core Studio is one hell of a machine, and even tops the M3 Ultra in some areas. But if you want more than 512GB of RAM, then neither will cut it. Possibly the M5 Ultra will be configurable with 1TB of RAM? But also possible that there might not even be an M5 Max, or Ultra.
You might find prices of digital storage hit the roof, and M4 Max stuff becomes hard to find, as M5 prices are suddenly a joke.
Let’s simplify it.
If you do sample-based Orchestral - then grab an M3 Ultra, from 96GB upward.
If you do Rock, or whatever - then grab an M4 Max 16-core Studio, with 64GB upward.
For live recording of a huge number of tracks - you can do your own research, but I’m betting it’s the Ultra. Or maybe 4 Ultras linked together?
Whichever way, unless you’re running in Linux, then the whole thing is tedious with the current state of core-utilisation. There are 3rd-party workarounds on Mac OS. You could use Audio Gridder for instance?
Or you could turn off Core 0?
Would be helpful if you state your musical intentions, ability-level, and whether this is a professional installation or not. Then I might have something more positive to give you.
