I’ve been Mac at home since 1998 and windows at work almost all of that time. I assume it’s the equivalent of being bilingual at this point.

Eventually you will get used to it.
You have 3 options.

1. normalise to OSX shortcuts (and concile your Linux shortcuts to those). You are more likely to encounter an osx machine “in the wild”, and if you have to get a new Mac then everything is instantly comfortable. Linux is also easier to customise.

2. normalise to your Linux shortcuts. Figure out how to script osx to adopt those shortcuts (so you can quickly adopt a new work machine), and accept that you won’t always be able to use those shortcuts (like when using a loaner or helping someone).

3. accept the few years of confusing Osx Vs Linux shortcuts, and learn both.

Option 3 is the most versatile. Takes ages, and you will still make mistakes.
Option 2 is the least versatile, but is the fastest to adopt.
Option 1 is fairly versatile, but probably has the longest adoption/pain period.

If OSX is in your future, the it’s option 1.
Option 3 is probably the best.
If you are never going to interact with any computer/server other than your own & other Linux machines, then option 2. Just make sure that every preference/shortcut you change is scriptable or at least documented and that the process is stored somewhere safe

I was in a similar situation.

I configured the Mac to use my expected shortcuts when possible and got used to the stuff I couldn’t change. I believe the mouse/track pad behaviour is pretty customizable, so you should be able to convert it to what you expect.

Congratulations on the new job.

I’m autistic so your mileage may vary with this advice, but:

Just make certain visual elements from the OS part of the context trigger for your skills.

“command-W” to close a tab becomes “ctrl-W”.

“command-right” to switch to next tab becomes “ctrl-shift-pageup” (that one works on mac too).

Each of those commands already exists in a context in your brain, such as “when in a web browser”, so just make the operating system part of that context. You can use visual cues for your subconscious to pay attention to, to activate the context. Like, the top bar or even the fonts of the operating system can be your visual cue.

It is possible, in my experience, to answer your question.

You can customize MacOS shortcuts and trackpad/mouse gestures and buttons to match whatever you’re used to (and more) using BetterTouchTool

It’s very popular software for this reason.

I changed all the KDE shortcuts to be like on Mac (because I like those more). I have a keyboard with Mac layout for my Linux PC and have swapped meta and ctrl via the keyboard settings (i.e. you press ⌘C but software receives ctrl+c), because a lot of non-KDE apps are way worse about remapping shortcuts so if they really want ctrl I at least want it to be on the ⌘ key, and also because the meta key behaves weirdly at least in Qt, for example it doesn’t block text input when held down unlike ctrl.

These are the big annoyances with this that do trip me up:

• Terminal (since I’ve switched ⌘ and ⌃, the standard shell keys such as ⌃C are now ⌘C instead because that is unremappable in Konsole, and I’ve had to put copy/paste/etc. on ⌃C etc. instead)
• Text navigation in Firefox — while I remapped the bindings for KDE/Qt, it’s impossible to do that in Firefox which means ⌥◀︎ is “navigate back” instead of “move caret back one word”. This is the most awful because it keeps making me reload pages when I’m editing text and don’t pay attention
• Text navigation in KDE/Qt apps — it’s so close to good but I can’t remap the “extend selection word left/right” keys from ⇧⌘◀︎/▶︎ to ⇧⌥◀︎/▶︎ to be like the “move caret” keys (⌥◀︎/▶︎). Same for the select to start/end of line keys.

Eh. There was a time when I was adept at macOS, windows, redhat, and SGI.

Yeah, I’ve had two jobs in Mac environments while running a Windows or Windows and Linux at home. When I’m tired is the time I make the most goofs, which is usually around the time I should get off computers for the day and touch some grass.

Interesting that track pad and mouse are specific annoyances for you. You don’t have to use an Apple mouse with an Apple computer, you can use other brands with a more robust scroll wheel.

I got a MacBook a bit earlier this year, and the keyboard took me a while to get used to, but I got used to it eventually and now I’m pretty comfy on both it and KDE.

That being said, you probably have way more of a muscle memory than me, as I’ve only been using Linux for around 4 years, so it might be a bit more difficult for you to get used to it.

Dunno about mac. I work on Windows for 10 years and have been daily using a Linux KDE laptop for hobby, gaming and casual use for 7.

Honestly, I just don’t think about it at this point. I even have a mouse and keyboard with fast switch between devices and just turn my attention to the other one when I switch.

Where do you work, and are they hiring?

You’ll get used to it with time. I use the Mac keyboard layout with my Windows stuff too now and it helps a little. I still use the Windows shortcuts on Windows though, I just mean the flipped alt and Win/Cmd keys.

Also, grab this program. The biggest loss from Windows on Mac is moving windows around with hotkeys. https://rectangleapp.com/

I find it incredibly annoying. Assuming dual boot or VDI to exclude physical differences, even things like the mouse scroll speed irritates me. Differences in scaling, differences in accomplishing simple but repetitive actions. I don’t have the patience for that anymore.
