HOW TO SAFELY DOWNLOAD & INSTALL PROGRAMS FROM THE INTERNET

In this article, I will explain how to safely download and install programs from the World Wide Web (Internet) on your Mac.

First, you need to check your system preferences because the default setting is for programs to be downloaded only from the Mac App Store. You need to open to System Preferences > Security > General and under Allow apps downloaded from: select Anywhere. If this selection is grayed out and you are not allowed to change it, you need to unlock your settings. You click the lock in the bottom left of the screen and type in your Administrator password. The screenshot below shows how the options to change will be gray, and it also shows the unlock screen that requires the Administrator password.

I strongly suggest you go back and change this setting back to something more secure after your download. There are two secure settings: Mac App Store or Mac App Store and identified developers.

Let me say that the safest and most secure way to install programs is through the App Store. Apple has strict security and developer standards that each program (app) must meet. Apple reviews each app before it’s accepted by the store, and if there’s ever a problem with an app, Apple can quickly remove it from the store.

Before the App Store appeared, we all downloaded programs via an Internet website, and for some programs that is still done today. For the security of your system, you should verify and trust the source website for those downloads. Personally, I trust few and always suggest using caution when downloading anything from the Internet. Whether it is a free or paid program, going straight to the manufacturer or developer of the program is always best. For example, if you want to download the Internet browser Google Chrome, it is best to get it directly from Google.

A good example of this is below. I simply searched on Google for “Mac Google Chrome download.” Notice that the very first selection is actually an Ad. In this case, the Ad is okay as it links directly to Google. Be cautious, thought, as often the Ad is not the best place to download and is just a paid for Ad that makes it the first selection listed. You can read below the link to see what the actual website address is. You will also notice that a few entries down I have a big X. Another misconception is that the pages with “stars” are reliable, but they aren’t always! Although Softronic and CNet have several stars, I try to NOT download from those websites.

Also carefully watch during the installation of the program, especially Internet browsers, for a checkmark box that will make this program your default Internet browser. If you do not want it to be, you will need to uncheck the box. Typically this option is one of the last screens in the installation wizard. Also note that the checkmark box can be a variety of things, so just remember to look at exactly what is listed before selecting next or install.

Once you have found the program that you want to download, you need to check and make sure that the program is compatible with your operating system. To check what operating system you are running, select the Apple logo  in the top left menu bar and then select About This Mac. You will see OSX and underneath Version 10.##.#. It is this version number that you need to check and make sure the program you want to download is compatible. You also want to check the hardware requirements of the program, like the GB of RAM required to run the program. Again, you can find all of your system information in selecting About This Mac > More Info.

After you have checked compatibility, have verified and trust the website you are downloading from, and lastly checked your security settings you are ALMOST ready to download the program.

Misguided places to download software is by trick buttons/links in advertising that is displayed on the website you’re intending to download software from. You must be careful and watch the website, reload the page and watch where the advertising changes so you don’t accidentally click a download looking button in an advertisement or you will be downloading something you won’t want or something malicious. I have a picture below of a great example of misleading download buttons.

So after you have visited the website, found the software you want, and determined the correct link to download, you are ready to click the link to download the program. Once downloaded, the file will be inside your Downloads folder next to the Trashcan. If you aren’t sure which one is your downloads folder, you can hover your mouse over the icon and the name of it will appear.

Within the Downloads Folder you will see all the items you have downloaded from the Internet. Find the file you just downloaded, either by name or by date modified and double click on the file. For Mac users, the file will have an extension of .DMG. If the file you downloaded is an .EXE file, do not open as this type of file is for a Windows (PC) computer.

After double clicking the .DMG file, the next step will either be a pop up window saying to drag the program to the Applications folder or an installer wizard will run and you simply follow the instructions. NOTE that installer wizards will often try to sneak a checkbox that will change your default browser or other settings, and so be careful and uncheck any box that asks to make changes you don’t want. OS X will ask if you approved of this download, and it will check to see if it’s part of it’s database of malware and cancel it if it is. Lastly, the system will may ask you for the Administrator password.

Now when you have finished installing, click and drag the installer package (.dmg file) to the Trash can. This turns into an Eject so it ejects the .dmg volume.

Security Tip:

You need to keep the Download Folder clear and empty and not store anything there for long, just to be safe. There is a possibility that bad or hijacked websites could cause a download without your knowledge, and on high-speed connections you won’t even see it sometimes because it’s so fast.

If a Trojan is lying in wait for you in the Downloads Folder and you double click on it to see what it is, it could compromise your machine. So, it’s just best to keep the Downloads Folder clean and clear except when in use.

MAC MAINTENANCE – What you can do

New Mac users and customers ask us what they need to do for maintenance on their Apple computers. That’s a good question. Apple’s marketing suggests computers “just work,” so many people never consider regular maintenance. For the most part Apple is correct. However, there are some things that you can do monthly and annually to keep your Mac running smoothly.

First, regularly update your software. Unlike a Windows update on a PC, your Apple OS and app updates will not mess everything up and you don’t need a tech friend to tell you which ones to do and which ones to skip. Access software updates from the Apple menu, then select Software Updates. For those of you with a newer OS, updates will be completed through the App Store. All of these updates include little and big fixes for issues that have been reported to Apple.

Next, get in a habit of organizing your files and archiving old files. This means if you standardly save files to your desktop, moving like-files to a folder or within your documents or picture folders. The more files that are not contained in folders on your desktop, the longer the desktop will take to open when you start up. Another good habit is repairing your disk permissions with the Disk Utility app that is built into the Mac OS. You can avoid problems by proactively running the disk utility every two to three months. This utility examines certain files and folders on your Mac’s hard drive to see if their current permissions settings are what Mac OS X expects them to be; if discrepancies are found, the offending permissions are changed to match the expected settings. That’s just a fancy way of saying that it makes sure all files are where they need to be.

Lastly, you need to periodically physically clean your computer – especially laptops. If you regularly eat while browsing the Internet or Facebook – all those good crumbs and gunk on your fingers are getting all inside your computer and on the keys. The best way to clean your laptop is first to turn it OFF. Next get a soft fiber cloth or old t-shirt and lightly spray it with Windex. Now you can use the rag to wipe both the keyboard portion, the display glass/screen, as well as the top and bottom of the laptop. Desktops and keyboards need to be cleaned as well with the same process. And for those of us with 4 legged friends, canine or feline, it is important to remember that all animals have dander, whether they shed a lot or not. Therefore, animals lovers (I am one too) will need to take your laptop to a professional to get it cleaned internally – where all that dander likes to go. It shouldn’t cost much or take very long. Computerlab charges just $20 for an internal cleaning.

That’s pretty much it. If you find your Mac has started to get slow and bogged down and you exhausted all that you know to do – take it to an Apple Authorized business with technicians that have current certifications. It is within your right to ask a business to see their tech’s certification. Apple requires technicians to obtain new certifications on each line of product because the new MacBook is internally different than a MacBook Pro Retina. Also, certifications expire! A “certified technician” who received his certification in 1999 is not qualified for a 2012 anything.

Oh and let me mention one way to NOT clean your Mac. At NO time should you ever download or run a program intended to clean your computer – this will cause you many more problems than it will ever solve. After downloading and running this type of program, you will have to see a professional for why your computer is running so poorly. We will talk more about these programs in a later blog.
