Can't Access Full Disc Access nor Accessibility Mojave 10.14.6 - 2nd Mac purchase!

Thank you for the quick reply. I'll try Safe Boot.

I did make a new admin account - allow read and write - and got the same result.

I've been told to reinstall the OS but surely if it's just out of the box , refurbished and ready to roll it shouldn't need a clean install. I did specifically ask for Mojave to be installed to allow me to use my older 32 bit audio applications - the default option was Catalina or Big Sur when i initially purchased but I knew the 2018 mini i7 can run Mojave fine. I'm totally gobsmacked myself for it to happen TWICE, both on refurbs albeit with 1 year warranties. My old Mac Pro 3.1. 2008 and G5 are still running great, this "upgrade" has been a nightmare so far.

ok , just tried Safe Boot - same thing - nothing is added. I should point out that I can drag and add from "+" options they just don't show in the settings at all - I'm not getting any errors about not being able to physically add the apps. They just don't go into the Accessibility or full Disc Access settings.

I have not installed any of my apps except SuperDuper and Teamviewer and only setup my own admin account, I've not done anything else except I had 3 Mojave security updates pending and I let the system install these.

I use SuperDuper every day for my audio drive backups and use Teamviewer periodically but both require access to the Privacy settings options to run.

With the previous refurbished purchase I migrated everything over from my Mac pro 3.1 and everything went fine, I authorised the applications that needed authorised, I have a ton on Ilok keys so that was even easier and the computer functioned great. It wasn't until I went to do a backup that evening using Superduper that I got the Full Disc Access notice, and then I checked other apps I havn't used yet and my Intego Security setup - I didn't get any warnings at the time of migration etc so I didn't think anything of it. Anything that needs Accessibility or Full Disc Access cannot be added. Because I was always on 10.11.6 I didn't know anything about the new security settings introduced in Mojave and since searching online there are a lot of users with the same issue, with different apps of course - their common denominator seems to be anti-virus and security installs. I do not have any security or antivirus installed yet , i just turned on the built in Firewall when the mini started up. I've also tried turning the firewall off (i'm really clutching at straws now!) and I know that if i was to disable SIPS it would work - this again is the common "fix". So, I'm at a loss really and as musician whose MACS have always just worked correctly, I don't want to try anything out with my basic comfort zone because i feel i shouldn't have to!

This is the EtreCheck report: There is a minor issue (I've underlined this) it says with Limited drive access (relating I suppose to Full Disc Access). I've never used Time Machine on any of my Macs but surely, because this isn't enabled, this can't be the issue?

Not that I know why I'm looking for but, In the Mac mini software logs I'm seeing a lot of this since way last year in the logs:

/dev/rdisk2: /dev/rdisk2: ERROR: volume /private/var/setup is mounted with write access. Re-run with (-l) to freeze volume.

and more recently: as in is yesterday:

/dev/rdisk2s1: /dev/rdisk2s1: ** /dev/rdisk2s1 (NO WRITE)

/dev/rdisk2s1:    Executing fsck_hfs (version hfs-407.200.4).

QUICKCHECK ONLY; FILESYSTEM CLEAN

Is this helpful?

I can't add anything at all, no applications,.. nothing.... to FDA nor Accessibility after unlocking the padlock. Nothing is going in, no apps are even showing then vanishing later - nothing at all. My last thing that I can think of to do will be a reinstall of the current Mojave OS. I assume the OS is already downloaded, ie I don't have to download anything to install the current OS.

I need Mojave to run 32 bit audio applications.

No , it's from a reputable company in london - hoxton macs.

No, my Intego Security is not installed on this macmini, it was migrated over with everything else on my PREVIOUS refurb purchase and again i couldn't add anything to FDa nor Accessibility. I'm doubtful I'll hear of a fix tomorrow from them because nobody so far seems to know why it's happened and how to fix it. The previous refurb Tech guy was superb at guiding me through things and they even sent me a replacement SSD as well to remigrate all my authorisations again to a new SSD but I got the very same result. I may ask them where these minis came from because they seem to come in batches - I asked to be notified when they got them back in stock and they replied that they should have them back in within 2 to 3 weeks and this was the case.

i have 14 days to return it anyway but obviously i'm now running out of options for my planned upgrade. This mac mini was a 1000 GBP cheaper than buying from Apple and it's in grade A condition, but of no use if i can't get full access to the drive! This may be the reason why they are so cheap!

yes, i'm the admin and access has read and write permissions

I've maybe done this wrong, sorry, but you can see the report anyway..
