My Mac mini (i7/1TB/8gb) arrived this week and came preinstalled with 10.15.3. In order to boot from my Mojave bootable usb stick, I had to turn off security on the secure boot screen / macOS Recovery.

Secure Boot = No Security

I couldn’t specify to boot from the usb stick as it was giving me the “the bless tool was unable to set the current disk” so I ended going back into secure boot screen and changing the external boot to allow. I didn’t read the second option, probably too excited.

External Boot = Allow


The Mac mini is running on Mojave 10.14.6 without the 2020-002 and Safari 13.1 update, reading other discussions about 2020-002 worries me so I’m skipping it for now. The usb stick was a standard Mojave installer made on my MacBook Pro also running 10.14.6. Took about 10/15 mins to install Mojave.

Now I’m waiting for the TR6 screwdriver to arrive to upgrade the ram.

Update: Installed the 2020-002 Mojave security update from the Apple download site rather than from Software Update within System Preferences. I've kinda always done that, then applied the update with the existing Apple 8GB RAM installed. System rebooted a few times then came back on after a few reboots and 5 minutes later. Then did a TimeMachine backup. Then upgraded the ram with the purchased 2x16gb sticks carefully and successfully. Mac Mini is back up and running and all seems fine.

simonb's report in post 27 above should settle the issue.

The so-named "2020" Mini can still boot and run Mojave.

Apparently no internal parts have been changed other than the drive sizes.
 
Man, are you ever narrow minded! It's not obnoxious at all. In fact, it's quite the opposite. Man, what planet did you come from?

(going to ignore that hilariously ironic insult.)

Did it ever occur to you people might need certain software to make a living?

Not all software is compatible with Catalina and not all apps or hardware drivers have working alternatives. Apple now forces people on Catalina even if their Macs came pre-installed with Mojave.
This wouldn't have been a problem if Catalina had the same app-compatibility, but unfortunately Catalina did not only break 32bit compatibility, they also removed support for popular plugin formats like HAL.

For me personally, some very expensive pieces of audio hardware, that are an essential piece of my workflow, stopped being compatible. This basically rendered my maxed out Mac Mini from 2019 useless and now I'm forced to use my much less capable Macbook Pro to continue my work. And I'm lucky I still had another Mac ''laying around''.

They also haven't added a 2020 model here. They would have, by now, if it was a new one. As you say, all it is is formerly BTO configs at lower price points.

Wow, you are actually stating something that makes sense.

This wouldn't have been a problem if Catalina had the same app-compatibility, but unfortunately Catalina did not only break 32bit compatibility, they also removed support for popular plugin formats like HAL.

Software incompatibility for a new version of the Mac OS has been around forever. If one must use a particular program that is not compatible with the newer Mac OS, then their choices are obvious:

1. Stay with the most recent version of the Mac OS that can run the software.

2. Use an "older" Mac.

There is no 2019 version of the Mac Mini. The 2 most recent ones are 2018 and 2020. When I purchased my late 2018 Mac Mini back on February 1st, it came with Mojave, OS 10.14.6, installed on it. I purchased it from Best Buy, so I suspect it had been sitting there (in storage) for a while. But I can use Catalina, as I have no hardware nor software issues.[/QUOTE]

I have a question about Security Update 2020-002, the T2 chip and Mojave on a 2020 Mini.

If the 2020 Mini has Catalina installed, it presumably has SU 2020-002 installed. It was my understanding that this updated the firmware version on the T2 chip. Retrograding to Mojave shouldn't change the T2 firmware version. (Correct? - I haven't found any posts here reporting a successful downgrade of the T2 firmware.)

So, if you successfully downgrade the OS from Catalina to Mojave on a 2020 Mini, you presumably still have the firmware update for the T2 chip installed?

Assuming that's correct, does anyone who is running Mojave on a 2020 Mini that was downgraded from Catalina have any of the problems reported with the T2 chip and SU 2020-002?

I realize this is probably a very small set of users and possibly no one here is in that set.

I did and Unfortunately I still do. Clicking ''About This Mac --> System Information --> Controller'' still tells me my T2 is on ''17P4281''. Same as Mojave.

1. If I could I would. But Mojave 10.14.6.2 made my Mac mini very unstable since it kernel panics about once an hour. Won't go into the whole story here; you can read about it in this thread: https://forums.macrumors.com/thread...02.2228812/page-4?post=28427884#post-28427884

Catalina runs fine though, but like I said, my software is't compatible.

2. Yes. I'm on my 2017 15'' MBP now but it's about twice as slow. That's beside the point though because not everyone has that luxury.

P.S. 2019 meaning I bought the machine in 2019. There is no 2020 version.

The 2 most recent Mac Mini models came out in 2018 and 2020. It did not come out in 2019.

I recently purchased my 2018 Mac Mini on February 1, 2020, so it is not the 2020 model (and of course not the fictitious 2019 one).
 
CoastalOR is correct. It was a pricing change only. Even the article referenced states: "While it’s still the same Mac mini from 2018, users now get more storage for their money on the two off-the-shelf configurations."

Then why is it referred to as "2020 Mac Mini"? I understand the specs have not changed, and thus it is "really" the 2018 model. But still it's referred to as the 2020 Mac Mini.
 
What planet are you living on? Read this:

The so-called "New" Mac mini with a price adjustment for double the storage for the base prices was announced available on March 18. I purchased a "New" Mac mini from the Apple online store on March 22 that was delivered March 30.

"About This Mac" shows "Mac mini (2018)".

If you choose to believe articles on the internet written by people that are trying to make money with getting people to read their "click bait" titled articles then enjoy.

I actually have a "New" Mac mini and there is nothing showing 2020.

BTW, to answer your question that you asked me, I live on a planet where you no longer exist. :D

hi, my Mac mini (BTO) that arrived from China in mid April came with 10.15.3 preinstalled. Software update informed me of the available 10.15.4 update as well as the 2020-002 update. I didn’t apply those and reinstalled with 10.14.6. Then later I applied the 2020-002 update to 10.14.6. So to me it looks like the factory is still installing older software.

Problem is now I get the unexpected crash error message on boot up from cold, and when I try to shut down, it turns the monitor screens off but the led is still lit. I have to hold the power button down a few seconds for it to actually shut down.

Sometimes if I log out then shut down, it works, and other times it still just leaves the led and fans on with no display till I physically shut it down. It’s a bit of a pain but I can live with it for now, hopefully Apple will fix that.

And not wanting to sound like an old broken record but this is a Mac Mini 2018 not a Mac Mini 2020. There isn’t a Mac Mini 2020 being sold by Apple......yet

I received my refurbished i5 16gb 1tb machine and had to downgraded to Mojave because I couldn’t get Citrix workspace to work on Catalina. Then I installed the security update (before reading this thread) and I’m getting the crash erorr message from a cold start.
 
I ordered the new Mac mini (i5/8/512) from Best Buy soon after the refresh and it came with Catalina installed. I downgraded it to Mojave right away so I never checked if it had the security update or what version of Catalina it had. I've installed all Mojave updates. I've had no issues with it. T2 firmware is 17P4281.

That's a defect in the OS.

Oh narrow minded one! Here is a link that show ALL the hits of a google search for "Mac Mini 2020":


Clearly WAY more than one article.

BTW, to answer your question that you asked me, I live on a planet where you no longer exist. :D

But you are not there! That makes it all the better, as I don't like clueless folks! :):)
 
Hi Mac people, would someone please be so kind to tell me that the Mac Mini I just ordered like today would be able to run Mojave because I have lots of older 32 bit audio apps that it would be a shame not to have to play with! Even my primary DAW has a new version that I can not afford right now and that version is more than likely more finely tuned to Catalina. The version I have I know will work on Mojave better!

YES it will.

But... but it will take some work to "get there".
