Hello,
Firstly thank you to anyone that reads this and provides helpful feedback, i've been searching through many threads trying different things with no success and I can't help but think i'm missing something more simple?! So here is my issue;
I've got a couple of pieces of software I need to use, both however incompatible and unsupported with Catalina, which i'm running. The most recent OS that they are both compatible with is El Capitan so i've downloaded the OS installer file with a view to partitioning my internal SSD and loading it on, then just running this OS upon startup when I need it and returning to Catalina for my normal everyday use, i'm absolutely happy with this solution.
Partitioning my hard drive - went through disk utility and tried to partition but all of the buttons are greyed out, it says "This container can’t be split because the resulting containers would be too small", as you can see below i'm using just over half of a 500GB drive so plenty of space?
After reading through a few threads to try and solve the issue it appeared that creating a New Volume was actually more advisable nowadays? so I gave up with the partitioning and tried creating a new volume which was successful, so i've got a seperate volume now called "Legacy OSX" where i'm looking to install the El Capitan installer.
Next I try the El Capitan install (I'm in Catalina, but assuming I will get a prompt screen where I can select my new volume to install to) but get an error message that my copy of El Capitan OS is "too old to be opened on this version of OS X (i.e. Catalina), note I D/L the install file from the Apple site.
Read a few more threads and decided to make a boot disk on a USB stick, got that all sorted using terminal and an Apple guide online, restarted my mac, held the option key and entered Startup Manager, located my El Capitan Boot Disk (USB) and launched the installer, accepted the licence agreement etc. and get to the window where you select the drive to install to and all I can see is my USB! cant even see my original hard drive or the new volume created either?? Now i'm a bit out of ideas, I could try and install El Capitan to an external HDD (I assume that is a possibility) but I dont think this would be the best option for the audio software I intend to use, i'm hypothesising here but i'd imagine it would slower, less smooth, and possible lag.
Really appreciate your help.
