For my Acer C740, I recall it being really simple.
The instructions were easy to understand and only had a few steps.
I removed a physical write-protect screw, booted to developer mode or something, ran a command in a terminal, and then it either flashed a new BIOS or I booted a Linux USB and flashed a new BIOS.
Either way, it's a regular computer now.
I can pop in any USB drive and boot whatever EFI-compatible OS I want.
I was paying $90 a month for cable TV. Something that I hardly watched. When I did watch it, half the time I was watching OTA channel that I could just pick up with rabbit ears.
I was spending more time watching YouTube (everything from car crash videos, to videos of people doing lawn care, to reviews of tech stuff), and I was getting fed up with the ads.
So, I stopped paying the $90 for TV, bought a new HDHomeRun with a new antenna, downloaded the Pluto TV app, and subscribed to YouTube Premium.
Now I get my OTA shows, get some of the stuff I liked with cable (The 24/7 Tosh.0 channel on Pluto TV is pure delight), and I can binge all the dumb shows I want on YouTube without a single ad getting in my way.
This sort of thing is why I won't get a controller that lacks gyro (or rumble).
Lots of games use those sort of things, but then some company like Hori releases a neat controller that completely lacks the hardware that has been pretty much a standard thing.
Of all the design decisions in GIMP that seem to make it so weird or different to someone coming from Photoshop, Adobe has put in 2X the amount of design choices into their software simply to try to thwart piracy.
The amount of stupid libraries and processes it loads and "requires" to run is just crazy.
A lot of it became apparent when Apple dropped 64-bit support a few years back.
Developers had a decade to update everything to 64-bit. All the fancy (and expensive) Adobe apps were 64-bit, but all their licensing dependencies and anti-piracy libraries were strangely still 32-bit.
People with legit copies couldn't run anything after upgrading macOS. Only those with cracked/pirated versions (that didn't load the 32-bit libraries) could actually use the software.
I have no doubt that the mess of libraries and copy protection that Adobe "requires" would prevent their software from working under WINE.
It can do lots of magical things, but it seems like the developers tried to make it as different as possible just for the sake of being different.
I'm sure that if you bring up something to a developer of GIMP that "isn't like Photoshop because it's buried under 4 menus", the only thing the developer will do to address the issue is release an update that then buries the feature under 5 menus.
They got their weird software with its weird name and they are PROUD of how weird it all is.
All I can suggest with it is to keep searching Google or YouTube on how to do things with it.
I've mostly used Affinity and GIMP over the years. Although my work just got me Photoshop so that I can explore some of its "smart" AI stuff to help with some things.
I've been paying $25 a month to run into relatives that all have their trees set to PRIVATE.
They're my cousins / second-cousins, and I'm not sure who their parents are or how they fit into my tree.
The site lets you look at US Census data... from the 1950s or some shit. So I can piece together family information upwards half a dozen ways to my grandparents and their parents and so on, but I can't seem to get any info from the system for anyone born after the 1950s.
I keep paying because I'm trying to solve a spooky family mystery.
anyone around when it came out will remember the excitement of super mario twins
