Hi there, I'm looking for a bit of discussion about best practices when upgrading operating instals when you don't have boot screens. There are a few reasons you don't have boot screens. I don't have them because of my graphics card. I'm running a GeForce GTX 750ti on my 2008 mac pro running 10.10.3. My usual method is to reinsert the old X2100 or something when I need to update. I boot into the OS, run the update and install the latest NVidia drivers (which come out pretty quickly). I then swap in the 750ti and run it for a bit to make sure I can take out the old one. My old card is starting to die and the process is quite annoying every time there is a point release. I don't know if there are any better options for me, or perhaps people running AMD/ATI cards. I'd like to hear from people about how they go about it and maybe do a write of the option for the wiki/sticky thread. It's one area of upgrading the GFX card that I've really struggled to get my head around. A few silly questions: - Is there a software render mode I can use to bypass the GFX card while I update the OS? - Is there any auto-installer to install the drivers headless?
