I have a mid-2010 Mac Mini set up in my living room that I use for occasional browsing and email. It came installed with Snow Leopard.

I swapped out the hard drive for a 256 gigabyte SSD and bumped the RAM up to 8 gigabytes. The machine is reasonably fast and is in a handy location. Additionally have it set up with a Neat desktop document scanner.

I’ve deliberately kept the machine running Snow Leopard over the years even though several new versions of OS/X have come and gone. Lately a nag screen kept popping up wanting me to update it to OS/X El Capitan. I resisted at first, but from the Apple podcasts I listen to the chatter is that things are slowly improving as Apple rolls out bug fixes.

So, I ended up saying yes to the El Capitan upgrade. The upgrade process itself seemed to go smoothly enough.

It wasn’t until I sat down in front of the machine afterwards that I realized saying yes to the El Capitan upgrade was a mistake.

The first thing I found objectionable is the overall look and feel of the new design. The menu text isn’t big or bold enough to stand out, and the aggressive use of white and wimpy light-colored pastels ruins the usability that extra contrast affords. You have to remember I’m coming directly from Snow Leopard to El Capitan, and the overall look and feel of the Snow Leopard interface is much more appealing and practical. If you can do so, put El Capitan directly next to a machine running Snow Leopard and the Snow Leopard machine is much easier to see and work with. Interface elements in Snow Leopard are much more prominent. Snow Leopard icons are far more recognizable, and menu text is bigger and stands out more boldly.

The next thing I noticed is that the Finder dumped all of my customizations. It has an “All My Files” folder that dumped some 1,200 files into one giant folder even those files reside in many different folders across the hard drive. Folders such as Movies, Photos and Music are completely missing from the Finder’s sidebar. They still exist but it’s necessary to go digging around for them.

Functionally El Capitan caused my Neat desktop scanner software and driver to utterly stop functioning. Neat has a multi-step work-around for El Capitan posted to their website. The work-around sort of fixes things partially but not really. If you have a Neat document scanner, DO NOT upgrade to El Capitan at this time unless you don’t want to use your scanner.

At this point, I was willing to live with El Capitan until Apple fixes all of the infrastructure problems. However, I ran into an infrastructure problem that turned out to be a complete deal-breaker.

I have a 6 terrabyte Western Digital MyCloud network attached storage (NAS) drive plugged in to my Apple router. Though the MyCloud drive functions perfectly under Snow Leopard, iOS, Android and any version of Windows, to my chagrin I discovered that OS/X El Capitan won’t stay connected to the drive. I could reboot the computer and regain access, but within a few minutes the Mac Mini would arbitrarily disconnect from the MyCloud drive. It even disconnected in the middle of copying a large file to the MyCloud drive. If you have a MyCloud NAS drive DO NOT upgrade to the current version of El Capitan.

That was too much. I made sure I had backups of pertinent files, including the all-important Neat Library database file. Then I dug out the DVD’s that came with the Mac Mini and made a fresh install of the version of Snow Leopard that shipped with it. I was able to use the Migration Assistant to restore pertinent files, settings and Applications from a current Time Machine backup.

What is Apple thinking? In my opinion OS/X El Capitan is worse than Windows ME, arguably one of the worst, most bug-ridden versions of Windows ever. I know what Apple is trying to do with the El Capitan interface and color scheme – they are trying to make it seem fresh, new and exciting. Unfortunately, it fails on basic ergonomics. The El Capitan interface is a nightmarish hurricane of weak pastels, hidden features and unreadable system text combined with a truly dysfunctional infrastructure.

Fortunately, I had the option of pulling the plug on El Capitan and going back to Snow Leopard, which is arguably the best-ever version of OS/X. People buying new Macs today do not have that option. Unless they’ve had experience with older versions of OS/X they will never know that they are buying into a computing eco system that left its best days behind it.
