I had to reset my Mac mini to Mac os Lion, and I can't update anything to a newer OS. I am trying to get to high Sierra but I can't download anything because Safari is absolutely useless and can't get a secure connection to any website, including support.apple.com that has the links to download old versions. How do I get this done because I'm stuck in a catch 22 of needing to update but my current version doesn't let me update until I update.....
Earlier Mac models
I understand that Mac is running Lion, but you quickly determined its version of Safari is practically useless. You are unable to upgrade it by following the instructions Apple provided in How to download and install macOS - Apple Support because Safari "... can't establish a secure connection to the server support.apple.com" or words to that effect.
Is that correct?
Please open the Terminal app - it is in your Mac's Utilities folder, and looks like this:
Select the entire line that follows below (triple-click to select the entire line), select Edit > Copy, and then Paste it into the Terminal window:
curl http://updates-http.cdn-apple.com/2019/cert/061-41424-20191024-218af9ec-cf50-4516-9011-228c78eda3d2/InstallMacOSX.dmg --output ~/Desktop/InstallMacOSX.dmg
... then press the Return key.
Keep that Terminal window open. If some kind of error appears please let me know what it says (you can copy from Terminal and paste it here).
If all goes well a InstallMacOSX.dmg file will appear on that Mac's Desktop. Don't do anything with it yet. Terminal will show the file download progress with labels Time Total / Time Spent / Time Left which you can watch if you have nothing better to do.
Wait for the Terminal app to stop updating those values. It will eventually finish and show the prompt you saw when you opened it. When it does, double-click the InstallMacOSX.dmg file to mount that disk image. Double-click the package installer within it. That will initiate an upgrade to OS X 10.11.x "El Capitan" which will be required prior to upgrading to anything later.
Please let me know if that works. If it does, then you will be able to proceed with upgrading to High Sierra through the App Store in the usual manner.

A few years ago I bought an used MacBook Pro Late 2011 model, and switched HDD and upgraded to High Sierra. I didn't use that computer much, but since I got a Laser engraver and wanted to use a laptop instead of a desktop to control it then i decided to get my old mac and wipe it to get it as fresh as possible.... worst mistake ever !!
After installing MacOS Lion I couldn't go to any secure site, open APP store, or any other Apple cloud/web stuff (not even this apple support page - so i has a windows computer with me to research)
Long story short:
1.- I used Internet recovery to install the macOS that came with computer (Lion)
2.- Installed google chrome (old and only version available) - This let me go to the support.apple.com website and click on the MacOS Sierra download link
3.- Installed that Sierra
4.- FINALLY !!! Able to open APP Store and downloaded High Sierra.
So there you go, use google chrome to jump over secured websites that couldn't be open with safari because of TTL security
