Mac mini 2014 Mojave slow.

[wellander1]

I have 3 2014 Mac mini's that work great in 10.13 but work slow in 10.14.
They all have 1.0tb hdd and 2.6 ghz processor.
(base units)
What gives?
Help.

Upgrading to Mojave converts the hard drives to APFS. That's all fine and good if your drives are SSDs but not so good for spinners.

So what do I do?
Apple should looked into this before release.
Or removed more computers from the compatible list.
Yes mine are spinners.(old style hdd)

You sure, you converted the HDD to APFS?

The standard HDD is slow. Like very slow... I upgraded mine (Mac mini 2014) to a 2560 GB SATA SSD and there is very big difference in speed and everyday use.

And one last thing: in your place, I would stay on an older MacOS/macOS version with older Mac minis. I have 10.12 on my MM 2014 model and Mojave 10.14 on the MM 2018.

Mojave runs well on my 2014 2.8ghz/8gb Mini. However, mine has a fusion drive and I split the 128gb SSD and am using it as the boot drive. With a traditional hard drive, I would agree that you're better off with an older version of MacOS.

I plan on upgrading my i5 MM(Late 2012), 2.5GHz, 16GB Ram, 500GB HD from Mac OS Sierra to High Sierra. Also, I plan on upgrading my i5 MM 2014, 2.8GHZ, 8GB Ram,256SSD from High Sierra to Mohave. I plan on doing this before the public issuance of Mac OS Catalina.
