I see quite a few replies on this thread talking about school\college. It seems the general consensus is that you can't use these computers well for that. Why? Is it the website and online portal's your school uses for turning in assignments and stuff? ... For anything that needs to be turned in through a poorly built web portal, you can stick it on a flash drive real quick and upload it using a modern computer.
I joined this forum about the same time I entered law school. At the time (2018) I had every intention of using a 1.67 GHz PowerBook G4 DLSD for my everyday, because in looking at the university's requirements for their online portal and other services, OS X Leopard was officially supported. Hard to believe (and it has since changed) but less than 3 years ago Leopard still met all of their security/printing/other requirements. As a PowerPC geek, this thrilled me to no end!
But my joy was short-lived. I had to quickly source an Intel Mac, or get a PC, because I soon learned the law school's requirements were more stringent than those of the university at large. One thing stood in my way: their proctored exam software.
I wrote about that here. Long story short, I picked up a 2007 MBP just so I could run El Capitan - which, it turned out, still didn't play well with their exam software. So I ended up with a PC laptop running Windows 8.1 Pro, which I used (and still use) almost exclusively for the purpose of taking these exams.
Then, with the pandemic came remote classes, and I again had no choice but to use the school's preferred vendor, Zoom. I was using my
17" 2006 MBP for that, until Zoom upped their system requirements to a minimum of Mavericks. At the time, I wasn't aware of
parrotgeek's hack to get Mavericks onto these systems, so it was back to the PC laptop or some of the various other x86 PC and Mac systems I have.
Believe me, I'd love to use a PowerBook for all that. I would if I could. Unfortunately, PowerBooks can't use Zoom, and transferring/uploading via a flash drive and a newer computer just isn't practical with timed exams and some of the other law school requirements. So, Zoom and exams leave me no choice but to use something newer for my school needs. That's my experience.
