Features lost across versions of macOS

Most of these are absolute whiny bullshit. Half of these are about progress. 32 bit app support? Yeah no shit, this isn’t windows. They’re gonna move forward at some point.
- Really pissed off about being unable to run half my Steam library
  
  Yeah apple sucks so bad for game preservation(see infinity blade), Linux is where its at for that.
  
  If half your library is 32-bit Valve games sure but just because Steam warns you, doesn’t mean it’s broke. As I don’t play any Valve games (CSGO, TF2, etc), the 32-bit games I do have will run just fine on apple silicon. Haven’t found one game in my library that won’t work due to 32-bit.
  
  Were you able to run it on Mac before an update?

Didn't forget the ability to uninstall pre-installed apps without compromising security and locking you out of updates (you need to modify the system image which affects SIP and also doesn't allow you to use FileVault disk encryption once disabled)...

I've been using OS X / macOS for over 20 years now, often alongside some Linux or BSD distro or another. For the past 10 I've been exclusively using macOS, but recently I've started thinking of ditching it for Linux.
The OS just gets more closed down over time, includes more and more really fucking creepy surveillance features, loses actually useful features, and gains bugs. Apple also has an incredibly annoying habit of coming up with new and possibly useful features that they introduce and then just leave to languish, or replace with a similar but more broken one; Automator & Shortcuts is a pretty good example of this. Or Aperture & iPhoto/Photos.
- Yes every macOS and Windows upgrade I've done at least in the last decade has felt like a downgrade where I lost something significant I was using regularly and gained nothing useful whatsoever.

  Oo, that seems useful, thanks for the tip
- I'm with you. It was always about the intuitive nature of the OS, and things just working, for me. All that seems to have gone out the window, and my ecosystem is just as frustrating as Windows at this point. I've been a MacOS user since 2007.
- KDE neon is pretty slick. Plasma 6 is a big step. Still lacks a decent replacement for Photoshop (no, gimp sucks).

  Why pay for Photoshop when Photopea is free and does what 90% of Photoshop users actually need to do? Also, GIMP has come a long way, it's more usable than ever and gets better with every new release.

Anyone arguing for Mobile Me and PowerPC apps is a crazy person.
This is a bizarre list that lacks context. Also, much of this functionality still exists, but it’s been rebranded or moved.
- There are some awesome games I grew up playing that I can't run anymore. Like this one https://www.youtube.com/watch?v=MK5PTq7vXA4
  
  You’d be surprised how much of this stuff has new ports, community ports, or can be run in an emulator.
  Here is EV Nova:

  That said, IMHO, compatibility from the Apple / Microsoft isn’t what really made this one hard to play. The developer went out of business and turned off some servers that the game needed. It looks like the community had to build off of a cracked copy of the game.
  
  Here is an alternative Piped link(s):

The big one for me is Time Machine lost the ability to delete that has already been backed up.
So if you work with very large files and they fills your backup drive... that's it. You need to either buy a new drive or erase it completely (losing all your historical backups). With the old Time Machine you could go through it and delete half a terabyte of data that never really needed to be backed up.

The missed Preview’s recent loss of the ability to open Postscript and EPS files. That was a real bummer

10.10 Yosemite • A legible user interface
Oh burn.
In all seriousness, this is an enlightening list. I knew someone of these like save as, but not others, like loss of antialiasing on non-retina Mac’s.
- I have a non-retina running 11, and it’s antialiased. So, lies.
  
  The new font smoothing is not the same with the subpixel anti aliasing it replaced. Thin text on non-retina monitors looks worse now than before. Most people probably don't notice it, but for those that do it was a major downgrade.

RIP Back to my Mac. You were the GOAT of your era.

Pretty sure I can live with it.

It was all downhill after Snow Leopard

I don't think this is a popular opinion, but for me Yosemite to Catalina was perfect looks wise. Mac OS became real ugly with Big Sur.
I dunno, I just really miss the gradients and the new design language of merging buttons and titlebar into one thick ass titlebar is plain horrendous to me.
- It’s all been downhill since Bug Sur.

Why did they replace bash with zsh?
- The bash that comes with macOS is a fork of the last version distributed under version 2 of the GPL, most likely because Apple doesn’t want to distribute GPLv3 code as part of macOS, and it is ancient. They keep it updated with security fixes but nothing else, so it has gradually become less and less compatible with current bash.
  Since zsh has become a popular bash replacement and it isn’t GPLv3, they switched the default shell to that.
  
  Thanks for the insight!
- Bash binary is still included in MacOS, right? It's just the default terminal shell changed to zsh.
  
  Yes, just checked)
- Not sure either, and kali did the same. https://apple.stackexchange.com/questions/361870/what-are-the-practical-differences-between-bash-and-zsh
  Of course, someone posted on stackexchange a nicely detailed post.

Every update depresses me as i know i will loose something important
