The captain said to his men “Gather round my merry men I’ve a terrible tail to
tell”. This is the tail he told … "It was a dark and stormy night …”
Once upon a time Craig did a port for mythtv. It was too hard to maintain and
building mythtv was incredibly hard. John Hoyt set about making an ansible
build that was a) much much easier b) made extensive use of macports.
A recent change to macports jpeg library meant that the mythtv bundle used the
macports jpeg library. John has resolved this but (before he did) in trying to
track down and fix the issue I caused chaos on my MacBook.
No worries, inconvenient, but I’ll just re-install. Gods snicker.
I created a bootable Catalina disk and tried that way. Soon to learn the error
of my ways (explains: security stops booting from an external drive)
I used the online tools to
a) format the disk as a case sensitive apfs drive
b) re-install Catalina (and there are reasons for not embracing Big Sur)
After restoring some of my stuff I had no space !!
I have 2 Mac OS - Data volumes. After much cleaning and fiddling it I have 1/2
drive space.
Who should I go to to ask for help on disk stuff (And the dark and stormy is
about going round and round eg enter passed to change security to allow ext
boot when main disk is blank. So Install os to change security ..)
Thanks James
