PSA – Safari 13.0.1 breaks multiple extensions

Even if you’re still running macOS High Sierrra (I’m on 10.13.6) you’ll receive a Safari update (from 12 to 13).  This will break a number of extensions – including most adblocking – also a vim-based keyboard extension I was using called Vimmy.

So you may want to avoid upgrading, or do as I’ve done and switch your default browser to Firefox etc. for the time being.

macOS Catalina 10.15 – things to be aware/wary of

  • 32-bit apps will no longer be supported at all (currently that still includes Acquia DevDesktop – for running Drupal development sites)
  • the default shell is going to change from Bash to Zsh
  • scripting languages won’t be installed by default (Apple gave Python, Ruby and Perl as examples in a support document, but didn’t specifically mention PHP).  It’ll mean Homebrew will need to be installed differently.   Presumably it won’t be an issue if you’re upgrading a previous macOS version, but, also presumably, it will be if you’re using a new computer, even with Migration Assistant.

(As usual, my own policy is not to upgrade to a new macOS release until 9-12 months after it’s come out, to allow everything to settle – I write this on a machine that’s still running High Sierra.)
