1. If you do GTD, you know that getting ideas out of your head and into the right list is key and to be able to do that while driving or as your walking to a meeting is a real improvement. Also, every one of my direct reports uses it (because I asked them to) and that allows them and me to have a shared running list of tasks that I have delegated.
2. Mar 03, 2021 Apple menu - About This Mac will tell you the Mac OS version or System version you are running. The X in the version is important, and so is the preceding 10 in the version if it exists. Questions saying X.1 could refer to Mac OS X 10.13.1, 10.1. Don't truncate the version you see.

Getting To Know You The following is our getting to know you questionnaire. This helps us prepare for your upcoming meeting by having an overall picture of your financial situation. It takes about 20-25 minutes, and you can save and resume at anytime.

Video Transcript: Hi, this is Gary with MacMost Now. On today's episode, let's get to know your Mac.Not everyone is a computer expert, so let's take a look at your Mac and all it's different parts, and look at the terminology used to describe it.So let's start by looking at the processor. Now, the processor--or, CPU--is the main part of your computer. It performs all the instructions. It's basically like the engine that drives your computer. Everything you do on your computer runs through the Central Processing Unit. That's why it's important to have one that's fast and powerful. Now, this is what a CPU looks like. This is the Intel i5 which is found in a lot of the current iMacs. It's basically a very large chip.Another important part of your computer is the graphics processor. Now, this is like a CPU, in that it handles instructions, but it specifically handles ones involved with displaying things on your screen. That's everything, not just 3D graphics. It's the windows in the Finder, it's the windows and documents of different applications. It's also called the GPU, for Graphics Processing Unit, sometimes VPU for Visual Processing Unit. I like to call it the Graphics Chipset, because on most Macs, like the iMacs and MacBooks and MacBook Pros, it's not actually a separate part. It's on the motherboard, so it's a bunch of chips on the motherboard. Now, here's what one looks like if it's separate, if it's a separate card, like you might find it in the Mac Pro.Macs also have memory, sometimes called RAM for Random Access Memory. They look like this. They're a set of chips usually on a small card that fits into your Mac. So, for instance, if your Mac has four gigs of memory, you may have two cards like this, each with two gigs of memory on them. Now, what memory does, is it handles data that you're using right now, like the document you have open right now in the application you're running right now.Now a lot of people confuse memory with storage, which is your hard drive. Your hard drive stores files, also called just basically storage by Apple, and it looks kind of like this, in some Macs. Some Macs have smaller drives, like the MacBooks, for instance. And in here, is--this is where all your files are stored, but files also include the entire operating system, and it includes also the files that define an application.Now, most Macs also have an optical drive, which is the real name for it, but you might also know it as the CD drive, DVD drive, or Super Drive. Now, Super Drive is capable of reading and writing CDs and DVDs. So, the difference between CDs and DVDs, by the way, is that a CD holds, uh, just somewhere around 800 megs of data, whereas a DVD drive holds just shy of five gigs of data.Now, of course, your Mac also has a display. You may call it your monitor or your screen, or just the LCD. Now, you may have heard a screen referred to as an LED screen. It's still an LCD screen, it's just using LED lights as the backlighting.Your Mac also has a variety of network hardware. For instance, you probably have a set of chips and an antenna inside your Mac that gives you WiFi access to your local router, which allows you to surf the Internet and communicate with other computers in your home. In addition, you may be able to hook up a wired connection to an Ethernet port. Gives you the same functionality, but you have a cable stretching from your Mac to the base station or router. Now, Apple calls wireless communication, a lot of times, AirPort. It's got an AirPort base station, you have an AirPort card or AirPort chips inside your computer. So the terms AirPort and WiFi are used interchangeably at Apple. In addition, you probably have Bluetooth capability in your Mac. This allows short range communication, uh, with some devices. For instance, uh, cameras may be able to send pictures, uh, you may have wireless headsets, you have, of course, wireless keyboards and mice, things like that.Your Mac also has a variety of other ways to connect to the outside world. For instance, you probably have a number of USB ports. This allows you to connect to devices like cameras, scanners, printers, wired keyboards, wired mice, all sorts of different things. It's the primary way to hook something up to your Mac. But also, there is FireWire, which is a different type of connection that is primarily used for video cameras. In addition, you've got a selection of audio ports. Some Macs have a single audio port that's both optical and analog audio in and out, so you can hook up a headset too it, like the earbuds that come with the iPhone to get both a microphone and headphones. Or, you may have separate jacks for audio in and audio out. In addition, you probably have a mini DisplayPort. Now, if you have an iMac or a MacBook with a screen, then this allows you to hook up a second screen. If you have a Mac Mini or a Mac Pro, this allows you to hook up your primary screen. Sometimes, you've got several on a Mac Pro that allows you to hook up several screens. In addition, some MacBooks have SD card slots. This allows you to take the SD card out of a camera and put it into your Mac to transfer the pictures from the card into your Mac.So that's the basic terminology used to describe the main parts of your Mac. If your interested in finding out any more of this, there a ton of information out there on the web. For instance, you can go to Wikipedia and look up any of these terms, and get detailed information about the different parts of the computer and history of those parts as well. Until then, this is Gary with MacMost Now.
