After having used Windows for all my working life, my new company forced me to switch to a Mac. I was terrified, unhappy and was not sure I would be able to cope with the switch. The first week was a nightmare, cause I had to unlearn all my shortcuts.
For starters, Mac has no backspace, no Windows Key, no Home, no End, no Page-up and no Page-down. Function keys are in the fancy touch bar and there is this key called "Command" which does most of the work. The mouse scrolls in the opposite direction, the concept of Desktops is different and there is no start menu.
Anyway, I have now been using the Mac for almost 3 weeks now, and I think I am surviving. I am confused with a lot of my shortcuts, but slowly and steadily I am getting my speed and efficiency back. The best part of learning to use Mac was to just Google search things like "How to Page Down in Mac" and you would get the right answer to your question almost always.
The interesting part though is - I hardly use any desktop tools anymore. Almost all my work is done in the Google Workspace suite. Though I am very familiar with the Office 365 suite of products, I am lucky to have also used Google Workspace extensively before.
My preliminary impression of Mac is not that extraordinarily different than Windows. Build-qualitywise Macbook pro looks definitely "cooler" than my trusty old Thinkpad X1. But that may have not been a big reason for me to change (ever).
I have almost found equivalent alternatives for all software that I used on Windows. The only problem now is that when I go back to my Windows Laptop, I mistype my shortcuts!
