For the last 39 years, PostScript has been at the heart of the Mac, bringing desktop publishing, fonts, and the LaserWriter and other printers. It has been removed from Sonoma.
TLDR: it isn’t really used, allows for code execution, and is old enough that it wasn’t designed with real threats in mind.
It’s used quite a bit when people export out from vector applications like Illustrator. I found it useful to be able to open those EPS files on Preview and was a bit pissed off when that option silently disapeared from Preview in Ventura
I have an old Brother HL-10H from mid 90s that’s still kicking using USB to LPT adapter and postscript driver. That thing is a tank, and isn’t likely to go any time soon. Guessing with this removal, it’ll also stop working when my last system upgrades to Sonoma and beyond?
