OK. Don't kill me for not studying better before posting. I'm a Mac Pro guy. Professional music studio where I also do video FCPX. I have MP 2019 7,1 and two 2010 5,2. But I'm about the throw in the towel and get the new Mac Studio. IDK anything yet about these "new" M4 Silicon Macs. Are they upgradeable? Can I add more ram? Can I expand the internal storage? I'm keeping my 7,1 for networking and storage since I have bogs of SSD in it. Also a lot of external SSD and spinning drives for backup and storage, I'm about to ull the trigger but I need ot know that, like in previous Macs, if I buy basic ram I can upgrade with 3rd party memory. For now I've picked M4 chip with 16 core CPU/40 Core GPU/16 Core Neural Engine. Whatever that is. Or will I be sorry for not going for the M3Ultra chip 28 core CPU/60 core GPU/32 core NE? I have the Apple Pro Display XDR. I hope I'll be able to use this!
