Have you used the external to boot another Mac? Do you still have that Mac (and will continue to boot from the external on that older Mac?) If no other Mac, then you could try upgrading the system on the external to one supported by the New Mac laptop.

From this thread - https://macosx.com/threads/use-imac-as-a-windows-monitor.327241/ 1. Your 2012 iMac would need a thunderbolt 1 connection to use for video in. 2. The source computer also needs a thunderbolt port, which leads to 3. 3. The 2012 iMac is too new for a DP connection, has to be a...

Try a deep reset - NVRAM reset: shut off your iMac, then power button to boot, while holding Command-Option-P-R Keep holding those 4 keys. You will hear a boot chime. Keep holding the same 4 keys until you hear the boot chime 4 more times. Release the keys, except continue to hold the Option key...

The difference is the type of file in those two screenshots. The first is the result of running the download .dmg file, which is an installer package (a .pkg file) The package contents are not viewable. If you launch that .pkg file, it will output the installer app that you show in your second...

Sorry we couldn't get you going. But, I think you came to a wrong conclusion. If you downloaded the dmg for El Capitan, opened that and ran the file inside to complete the installer app for El Capitan, then you did NOT get an updater. It was, in fact, a full installer, 6.22GB in size. Full...

Were you able to make the external USB installer?

You can't do the installer setup install on the M2, because the M2 is not compatible/not bootable with El Capitan. So, won't allow copying the installer to a Mac that can't boot from that system version. But, you could do it on the Mac Pro that you told me is at work. Keep in mind that when you...

If you want to change the format (actually, the "scheme") to GUID, you have to erase the drive (the device), not just the partition. You should see that the topmost item in the list for your drive in Disk Utility, will be the device (which shows the manufacturer's info/model number/etc, not just...

Sorry, I though, from your first post, that you already have a bootable USB installer made. This will be a long post, as I want to post the steps to make your USB installer, and get past those "evil" terminal commands, too! (Important question here), Does your MacPro boot successfully, so you...

I think that your settings/bookmarks for Firefox might be lost. But, as your system installation is very recent, and that your Firefox setup is important to you, that you might consider wiping the drive, reinstalling Ventura again, and (again) migrating from your existing Time Machine backup...

You can make a bootable installer on your M2 mini, which is a simple task through the terminal. All you need is a copy of the installer app for the system version that you want to use. But, that will just give you a bootable installer, which you cannot use from your M2 mini (it is not...

You could drag and drop a fresh download of Firefox, to replace the app where you are keeping it. You can make sure about that location by right-clicking on the Firefox icon in your Dock. You will get a dropdown menu. Choose Options, then "Show in Finder". Open your Force Quit window--It's under...

"...the icon moves as if it were going to launch..." Do you mean the Firefox icon in your Dock? Or, are you double-clicking the app itself? What happens if you click on the Firefox app (just single-click to select it), then type Cmd+o ?
