mac mini

I had to pause some of my work getting a current-gen AMD graphics card running on the Pi 5 and testing a 192-core AmpereOne server to quickly post on the M4's efficiency.

I expected M4 to be better than M1/M2 (I haven't personally tested M3), and I hoped it would at least match the previous total-system-power efficiency king, a tiny arm SBC with an RK3588 SoC... but I didn't expect it to jump forward 32%. Efficiency gains on the Arm systems I test typically look like 2-5% year over year.

The M4 mini I just bought reaches 6.74 Gflops/W on the HPL benchmark.

I can get 283 Gflops at 42W, versus 264 at 66W on my M1 Max Mac Studio (for a round 4.00 Gflops/W).

No stranger to rack-mounting Macs that were never meant for the task, I reached out to MyElectronics to see if they had a rackmount solution for the Mac Studio when I bought mine in March.

They said they were already working on a Mac Studio Rack Mount system, and they'd gladly send me one to review, since they knew how much I loved rackmounting my M1 Mac mini and all the Raspberry Pis I run in my homelab.

After upgrading my main workstation to a Mac Studio, I decided to break tradition.

Usually, I sell off my old workstation to offset the cost of the new one. But just last week, Asahi Linux announced their first alpha release.

If you haven't heard of Asahi, it's a Linux distribution based on Arch Linux that aims to bring a polished Linux experience on Apple Silicon Macs (all the current M1 Macs, and any new Apple Silicon Macs that come in the future).

Last month, I built an all-AMD PC to try out Linux Gaming with Steam and Proton, and so I'd have a faster native Linux build machine for my various compilation tasks.

This month, Apple introduced the Mac Studio, and as a now full-time video producer, it was a no-brainer for me to upgrade from an M1 Mac mini.

My Mac Studio arrived Friday, and over the weekend, I spent some time benchmarking it against not only my M1 mini, but also my new AMD Ryzen 5 5600x PC build.

My Mac Studio's specs:

Ah, the feeling of unpacking a brand new computer:

In my case, I'm actually selling the 16" MacBook Pro pictured above and replacing it with a 13" MacBook Air and 10 Gigabit Mac mini.

Once you turn on the new Mac, what's next? Do you:

tl;dr: If you see weird errors when using or formatting a drive internally on a Mac (especially after upgrading to a newer and/or faster SATA hard drive), it could mean the SATA cable needs to be replaced.

Who would've thought such a tiny cable could cause so many problems?

I have an older Mac mini (mid-2011 i5 model), and I use it as a general media server and network backup. It handles Time Machine backups for two other Macs, it has about 20 TB of external storage connected, and I also use it as a 'home base' to store all my Dropbox, iCloud, and Photos content locally, and store an extra Time Machine backup of all that. I'm a little nutty about backups... but I haven't lost a file in two decades and I don't want to start now ;-).
