How to install Mojave on a 2018 Mac mini that came with Big Sur?

I recently bought an open-box 2018 Mac Mini to replace a much older one before it dies. I wanted something that would run Mojave since I have some important, orphaned 32-bit software I need to run. Unfortunately (or not) the mini came with Big Sur installed and Recovery won’t go back to anything earlier. My plan now was to install Mojave on a separate partition so Big Sur would still be around to fiddle with. I have been unable to do that.

I used softwareupdate —fetch-full-installer etc. to get a recent, clean copy of the Mojave installer. I then used —createinstallmedia (with and without —download assets) to make a bootable installer on a thumb drive. It actually took me several attempts before it didn’t give an error message (one or more of the BridgeOS packages couldn’t be downloaded.) The resulting installer-on-a-stick boots, the apple logo comes up, and a progress bar starts. Eventually (maybe as long as a half hour) the bar gets to the end and it just sits there. No error messages, no nothing. Note: I did NOT wipe the mac mini’s internal drive before trying to boot the installer. I’m willing to do that if necessary, but only if someone tells me they’ve successfully installed Mojave that way and couldn’t do so without doing the erase.

I took the fetched installer over to my 2012 MacBook Pro and it executed fine and I was able to install Mojave on a partition on an external drive and boot from it (on the MacBook Pro.) I also took the thumb drive bootable installer over to the MacBook and it booted fine; I quit before actually trying to install Mojave, but that at least showed that the installer on the thumb drive appeared to work. So, the installer’s good and the thumb drive is good.

I then tried making a Catalina installer the same way. That worked like a charm and I was able to install it on a separate partition on the mac mini so now I could dual boot into either Big Sur or Catalina.

Whether relevant or not, I tried disabling SIP and Gatekeeper (spctl) on the mini, but that didn’t help. Suggestions? It certainly should be doable since I understand that model Mac mini originally shipped with Mojave. I’m willing to completely wipe the Mac mini’s drive if that’s necessary, and guaranteed not to brick it, but I shouldn’t have to do that, you’d think. There are some possibly relevant threads here that I’ve skimmed, but I didn’t see any that described exactly this problem. I’m pretty Mac savvy, but when it comes to firmware updates and the T2 chip I’m afraid I get lost.

So, let’s restate the question. How do you install Mojave on a 2018 Mac Mini that came with Big Sur? (Either on a separate partition or replacing Big Sur.) You get extra credit if you can tell me why the installer hangs for me at the end of its boot. Has anyone else encountered this problem? I know you can “solve” it by using any of several Virtual Machine packages, such as Parallels, but that would be my last resort.

disk utility – How to use internal HDD as a file sharing drive if I boot from external SSD on mac mini?

I’m running Mojave 10.14.6 on mac mini late 2014.

It has internal hdd drive. I bought an external ssd to speed things up and run everything from it, and use internal hdd as a data storagetime machine

I installed OS on ssd and am running the mac from it, but I can’t seem to erase the internal hdd drive. When trying to partition it in Disk utility I’m getting an error

The volume “osx” on disk1s1 couldn’t be unmounted because it is in use by process 82 (securityd)

After this error happened, disk utility shows that hdd has two partitions, 500gb each (that’s how I set it up on ‘partitioning’ step), but I can see only the partition that was there before, no new partition that I added. Might sound confusing – please see the screenshots here.

Now, I’m very sure that I run OS from external SSD, so I don’t understand why any process would use internal hdd and what should I do from now on.

So the question is, how do I use internal hdd as a data storage drive, and erase the OS from it?

iphone – Using Model i phone 12 mini( A2399) in USA?

really appreciate if someone can answer this question for me, my issue is that if the 1 phone mini model (A2399) bought in Asia can be used in USA in its full capacity specially the 5G network.

according to research done online about bands it says T mobile supports band “n41”, n41 is also said to be in the A2399, so will i be able to use 5G when in USA?

secondary question in atleast will i be able to get the highest 4G speeds in USA on this model in case I cant use 5G.

lighting – How do I set up the PocketWizard Mini TT1 and Flex TT5 with a Buff monolight?

Disclaimer: I have never used PocketWizards, but I worked as a technical writer for a few decades. I just went through the maze of “documentation” on the PocketWizard website (looks a lot like a written-by-engineers wiki); so I see why you asked. 😀

  1. Since the 5DMkIV may be too new to be compatible with the TT1/TT5, you need to set at least the TT5 in Basic Trigger mode with the PocketWizard Utility which you can download and see instructions for here. The AlienBee B800/sync cable connection can’t do TTL/HSS/remote power control anyway, so you’re not losing any additional function this “single-pin mode” turns off. You also need to set (hopefully) camera compatibility and the two configurations the triggers let you use (e.g., you can use C.1 as your “single-pin” with the monolight, and C.2 as a TTL configuration for a speedlight). This only before the first use of the triggers.

  2. Put the PocketWizard Mini TT1 on the camera hotshoe. (It can only be a transmitter).

  3. Cable the PocketWizard Flex TT5 transceiver (can be either transmitter or receiver) to the 1/8″ sync connector on the AlienBee B800 (a mono 3.5mm (1/8″) to 3.5mm audio cable should work).

  4. Power everything on “from the top down.” Start with the TT1, then the camera, then the monolight, then the receiver. Wait 2-3 seconds between each power on. Make sure you use the configuration setting (C.1/C.2) you set up in Step 0 on both units.

  5. Set the PocketWizard units to use the same channel. Set a group on the TT5, and make sure that group is set to fire on the TT1.

  6. Set the 5DMkIV so that it treats the Mini TT1 as if it were an on-camera speedlight; not a wireless master. Make sure all wireless flash settings in the camera are disabled, and that flash is turned on.

  7. Make sure the monolight is not set to use its optical slave for firing.

Now, when you press the shutter button on the camera, the AlienBee should fire. Because you have cabled the receiver to the light, the only thing your camera can tell the light to do is when to fire. All settings changes need to be made on the monolight directly through its own controls.

Alternatively, you could switch from the PocketWizard triggers to Paul Buff’s Cybersync triggering system, and, depending on which triggers you choose, you could regain remote power control over the monolight. Or consider eventually moving to the Godox system, which has sort of replaced Buff as the low-cost system of choice.

How can I send SMS messages from an iPad mini with cellular connection?

My mother has an iPad mini with a cellular connection.

We tried to send a SMS to her sister using iMessage but this does not appear to be working.

First I added her sister as a contact with the only contact info being her cellphone number.

However when I selected her sister as a recipient her name is shown in red and when I pressed send nothing happened.

Should this be possible?

I read that one can pair the iPad with an iPhone to get this working, but we do not have an iPhone.

I also contacted the mobile operator and the SIM card is ready for texting.

Is there some other app we can install on her iPad to get this working?
Or should we subscribe to a mail to SMS service?

macos – Can Mstc windows remote desktop connect to a mac mini m1?

Can I use Mstc Windows Remote Desktop to access a Mac Mini m1 where both are running under my local network ? Mstc work well from windows to windows. Is it possible to us it instead of adding some extra tools which can be less optimized ?

I planned to buy a Mac Mini and plug it to my internet box. So, I would access my Mac Mini from my windows.
