Hi, I'll give more information to someone, who is willing to help me.

in my MBP 15-inch, 2017 with macOS Big Sur ver.11.7.1 I have music softwares with old version and new version.

A new version softs are fine with a Big Sur but to use without mistakes old ones I need High Sierra as I done before.

That's why I need temporally Install High Sierra to an external SSD and work for a while switching between two macOS's

Thanks in advance.
