The update to 10.12.1 killed my Terminal routine I used to prevent Chrome from updating itself. Chrome version 53 is the last one that works with Epichrome app for creating site-specific browsers.
Chrome v54 mangles existing Epichrome SSB apps & makes them unusable.
I keep a copy of Chrome 53, Cappuccino SSB & a text file showing the Terminal method in a zipped file in Dropbox. I had to use that to recreate the Cappuccino SSB a few minutes ago.
FU, Google bastards.
