Operating Systems OS X (Apple) Warning! Upgrade to Catalina 10.15.3 Crashes MacPro (2013) - Will Not Boot ! Post 303043504 by Neo on Thursday 30th of January 2020 01:57:00 AM

Warning! Upgrade to Catalina 10.15.3 Crashes MacPro (2013) - Will Not Boot !

WARNING!

Just upgraded my MacPro (2013) from Catalina 10.15.2 to 10.15.3.

After the routine download and restart for upgrade installation, the Mac would not boot. Totally crashed.

Now, I'm in the process of a 15 hour restore from my last time machine backup.

I'm not very happy with Apple at the moment, to say the least.

The default is to write to standard output. --modules=MODULES Pre-load modules specified by MODULES. --install-modules=MODULES Install only MODULES and their dependencies. The default is to install all available modules. --themes=THEMES Install THEMES. The default is to install the starfield theme, if available. --fonts=FONTS Install FONTS. The default is to install the unicode font. --locales=LOCALES Install only locales listed in LOCALES. The default is to install all available locales. --compress[=no,xz,gz,lzo] Compress GRUB files using the specified compression algorithm. --directory=DIR Use images and modules in DIR. --grub-mkimage=FILE Use FILE as grub-mkimage(1). The default is /usr/bin/grub-mkimage. --rom-directory=DIR Save ROM images in DIR. --xorriso=FILE Use FILE as xorriso. --grub-glue-efi=FILE Use FILE as grub-glue-efi(3). --grub-render-label=FILE Use FILE as grub-render-label(3). --label-font=FILE Use FILE as the font file for generated labels. --label-color=COLOR Use COLOR as the color for generated labels. --label-bgcolor=COLOR Use COLOR as the background color for generated labels. --product-name=STRING Use STRING as the product name in generated labels. --product-version=STRING Use STRING as the product version in generated labels. --sparc-boot Enable booting the SPARC platform.
