Also i have a Macbook now, never had one. Should be interesting, I’ve only used Windows PCs for basically all my life. It’s also tiny but can’t really comment yet. I have used iPads and obviously iphones before, anything I should know before diving in?
You're not saying which model, but "tiny" leads me to believe MacBook Air and since it's new, probably Apple Silicon, or M1 for short. Hopefully. Intel is pointless at this point.
Software downloads usually come as ".dmg" files. This is a disk image. Doubleclicking the file will mount it on the desktop. Unless there's an installer in there to run, "installing" means dragging the app icon to the Applications folder. You can then unmount the image and throw the dmg away.
Obviously there's a Mac App Store just like there's an iOS App Store and I recommend getting software from there if available because it makes life easier with updates, etc. They happen automatically like on iOS. Some special tools that hook into the system aren't allowed in the App Store, just like on iOS, but unlike on iOS the Mac allows sideloading aka downloading directly from the developer. There's no digital nanny stopping you from doing whatever you want.
This concludes the Mac crash course.
If it's an M1, battery life will probably be several orders of magnitude better than anything you've used before. I don't use my M1 Air that much since I have a desktop mac (M1 Mini) for the daily stuff but I still open it every day. I charge it
maybe once a week and I'm not even joking. It's like Nokia phones of old. Obviously if it's going to be your main computer it's going to be charged nightly, but it's still on a different planet compared to any x86 machine I've ever used and certainly compared to any ultrabook. Especially considering how fast the M1 is.
Apple did bet on the wrong horse when they went all-in on face ID just before a worldwide pandemic. Thankfully my Apple Watch unlocks my phone for me if it detects a face mask. I can just picture the boardroom discussions at Apple, deciding whether to fast-track a return to fingerprint readers or wait for the plague to blow over.
Edit: By the way, I came from an iPhone 7 (same chassis as SE), upgraded to an XR and then to a 12 Pro. The XR was a nice upgrade in battery life but even more so was the 12 over the XR. Advances in chip architecture ftw.
