Hey guys,
I'd greatly appreciate any help i can get with this.
I just bought a macbook pro 2019 with mac os catalina on it. I also got a samsung T7 the other day. I'm hoping to use the T7 as a bootable hard disk with high sierra on it.
I tried two things -
1) tried downloading high sierra from the app store after visiting this link - https://support.apple.com/en-us/HT211683, but got the message the following message -
'Update not found.
The requested version of macOS is not available.'
downloaded a .dmg of high sierra 10.12 off this page - https://support.apple.com/kb/DL1946?viewlocale=en_US&locale=en_US, I open the .pkg file but get a message saying 'This software is not support on your system'.
downloaded an iso of high sierra off a website (not sure which one). This is the message i get when open the file and try to install it -
' “Install macOS High Sierra” cannot be opened because the developer cannot be verified. '
Please help me.
