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.

I had it like that and it was OK for two years or so until someone broke in at home while I was sleeping and stole my iMac.

So from my experience it gets better. Later I had to work on a Windows machine at work that again took a couple of weeks but eventually I also was OK using both at the same time.

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.

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.

Most definitely. I used to carry 3 laptops with me, one being Windows, another being my MacBook, and another being a Linux laptop. I now only carry the Linux and Windows laptops and traded the MacBook for a newer iPad Pro. I definitely became accustomed to all 3 OSes keyboard shortcuts.

You do find some overlap which helps. Mac was a bit of a struggle and still is with my iPad’s keyboard in figuring out whether it’s CMD or CTRL key for the shortcut. Even worse was when I used it to remote into a Windows computer as some used one and others used the other as the CTRL key in Windows.

Just takes practice and you grow as you go, the more you use it.

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

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.
