upgrade from OS X 8.5 (Mountain Lion) to 10.13 (High Sierra)

hi jim,

I have that exact same mac mini server model which I use as a development
environment. Last Known Good Mini…

Don’t even try to upgrade without installing SSDs – performance will be
abysmal. Also totally agree about the 16GB memory upgrade.

And yes 100% make a clean fresh new Time Machine backup, don’t use the
crufty old one that has 1.5 years of TM backups…

The 1st time I upgraded the hard drives a couple of years ago, I did it
myself. I’ve been rebuilding, upgrading and repairing macs since they were
invented, PCs too. I followed the iFixit video and I was still cursing 45
minutes later.

When I got a fantastic ebay deal on 2x Samsung 850 EVO PRO 1TB drives this
year, I paid my local (not the Apple Store) techs to do the next one for
me. It was $125 and worth every penny. I did my own data migration ahead of
time so that all they needed to do was the physical drive swap. SSD was
like a new machine. Worth every penny.

I would never again replace the internal HDs on this or any other mac mini
model myself. there is a special place in hell for the engineers who
designed the internals of the mini server dual drive model. Steve Martin’s
Cruel Shoes come to mind.

Also if you upgrade the format of the SSD to apple’s new APFS you will not
be able to read it from any other earlier version as a target mode disk.
considering how potentially buggy this new drive format may be, I have
opted to remain with the older file system on my 10.13 installation.

I installed using this workaround process, and it’s working well:
osxdaily.com/2017/10/17/how-skip-apfs-macos-high-sierra/

I am sticking with Yosemite for my dev environment for now, because I hate
the UI from 10.11 onwards. I have 10.10 on one drive and 10.13 on the other
and can switch back and forth no problem.

yeah its a security risk, but little snitch keeps things in line. plus
there was this glaring issue on 10.13:

MacOS > 10.6 = sucks under the hood.
steve jobs death ÷ apple quality control = sucks for MacOS.
stop buying back stock and spend some of that money on QC instead.
Linux becomes my friend more and more every day…

My 2¢
