Last week I bought an M4 Pro Mac mini with 24GB RAM to use as my “beta testing” machine. I don’t want to use my main machine for beta OS testing, so figured this config would be perfect for that.
However, there have been several times when running Xcode 26 on macOS Tahoe, along with a simulator or two, that memory pressure has gone up into the “yellow” and keeps increasing. I am surprised that 24GB doesn‘t seem like enough RAM.
I don’t have giant projects or use anything else on this machine. It’s pretty simple stuff.
Maybe this is to be expected with betas: memory leaks, non-optimized code, etc.
I’m considering returning the machine while I can. What do others find is a good amount of RAM for fairly modest development needs?
