[petsc-users] Difficulty installing PETSC-3.17.0 on new macOS Sonoma

[Satish Balay]

replied on petsc-maint

xcode-15 changed considerably, (fixes are in petsc-3.20)  that its not easy to backport all needed patches to 3.17.0

So best bet for petsc-3.19 and older is to use linux (remotely or via VM) - or downgrade to xcode-14.

Command Line Tools 15.0 (CLT 15.0) used to be the source of my problems with the previous OS version for which the solution was to install the old CLT 14.3, however, CLT 14.3 is not compatible with macOS Sonoma (which INL is requiring us to have).
