I have been back on Linux full time for almost a year now and there are a few things I miss.
I love, use and even contribute occasionally to open source software but it does not work well for a lot of tools.
I miss some of the excellent apps on MacOS:
There is also a some software I would like to be able to try for personal use:
Reliable graphics and hardware
Screen tearing, displays disconnecting from my dock and draining battery when it should be sleeping are all issues that I really wish I did not have to deal with.
Gnome window management does not make sense to me. Their is either multiple workspaces on one screen and a single workspace on the other. Or workspaces that span both displays but when you hit the meta the illusion breaks. Instead of seeing just the windows for the open workspaces, one display shows what you expect of only the programs open in that workspace on that display, but the other display shows every single window open on that monitor. This drastically reduces the nicety of having two displays.
Work requires that I have Linux given the tools we rely on, but I really miss some of the polish of the Mac ecosystem. For personal usage I will probably buy a Mac laptop when I can justify a reason to get a new personal computer. For now I have a Linux desktop and an old personal laptop at home.
