Here are 5 things you should know.
1. Your TV has a default setting that screws up Motion Blur, and should be turned off.
Sometimes called smooth motion, many TV makers have this on by default. But the American Society of Cinematographers wants that turned off by default. It ruins how they intended their film and TV shows to look.
It might be fine for sports, but for things shot in the normal cinematic 24fps, it removes the intended motion blur. This effect is sometimes called the Soap Opera effect because it makes it look more like it was shot on soap opera 30fps video cameras.
So make sure your TV’s smooth motion is turned off.
2. Many fire departments will give you smoke detectors for free.
As fire departments have a vested interest in keeping fires down, many municipal fire departments have free smoke detectors that they will provide you and give instructions on how to install. If you live in a home that doesn’t have one or has too few, call your local fire department’s nonemergency number and ask!
3. Cars are required to stop when approaching a school bus with flashing red lights and/or an extended stop sign.

This law applies to the US states.
First and foremost: TRAFFIC LAWS IN THE US VARY FROM STATE TO STATE The driver is responsible for knowing the laws where they are driving. A good summary of this case is here.
Even though there is a stop sign on the bus, it isn’t a stop and proceeds with caution situation like a stop sign. You must remain stopped until the lights turn off and the sign is retracted.
Cars are expected to stop in both directions, with some exceptions.
In some states, you do not have to stop if you are in the oncoming lane and there is a physical barrier or median strip. In some, you don’t have to stop if it is a multi-lane highway.
Buses may or may not have a physical stop sign that extends from the side. In general, if there are red lights flashing you are expected to stop. Again this may not apply in all states, but this is the safer scenario.
Yes, kids should be educated to cross the street safely, but this law is intended to create a virtual intersection where you would be able to cross with the same expectation of safety as you would have crossed at a traffic light. More so in some cases, because in some states when a bus stops and flashes its lights at an intersection, cars are expected to stop in all 4 directions.
Some localities route their buses so that the kids do not have to cross the street to board the bus, but this is not always common in rural areas.
In some cases, even emergency vehicles need to stop.
Violating this law has some of the most severe penalties for a moving violation, including large fines, license points, and mandatory suspensions.

5. If you hold down the “New Tabs” button in Safari it opens a window of all your recently closed tabs regardless of the originating iOS or MacOS device. This is the only way to view closed tabs in chronological order.
It shows the 25 most recently closed tabs, which most people have no idea the function exists. If different iOS devices are signed into the same iCloud account, you can reopen closed tabs on another device.
