Safe Travels with Your Mac or iOS Device
Avoiding Icky Public WiFi
Free public wifi is convenient. It's available just about everywhere these days, but its safety is questionable. Even if you are diligent about not logging into financial sites or doing anything of the like while on one of these networks, there still is a risk that your information can be intercepted.
The good news is that there is a simple solution: set up your own wifi network. This can be as simple as tethering to your iPhone by enabling Personal Hotspot or purchasing a mobile hotspot device from your phone provider. In this way you will be using your provider's cellular data network vs. a wide open public wifi. And yes, we have all read about fake cell towers jacking our data connections. This does happen. Nothing on the Internet is risk free, but by using your cellular data connection you are at least hedging your bets.

Clean Up Your Mac the Easy Way
Make Room for More Stuff
If you have had your Mac for a while, chances are it's plugged up with iPhone backups from 2008, old iTunes TV show downloads, or any number of old documents that you just no longer need. Well, if you are on macOS Sierra (and yes, you have to be on macOS Sierra) there is a new "Manage" tool to help you clear out old files and apps.
First, go up to the Apple in the upper left-hand corner of the screen, and from that drop-down select About this Mac. Click on the Storage tab and there you will see the Manage button. Give it a little time to calculate, but here you will have the ability to see what's clogging the drain and get helpful solutions on how to handle all that stuff.
BUT FIRST! Make sure that you have a backup before deleting stuff, because if you delete something by mistake, it would not be fun.

New Mac: How Much Space Do You Need?
128, 256, 512 - Oh My!
Time for a new Mac? If you have a machine that is from 2011 or earlier, that means you. But, how much space do you need? It's important to figure this out before you buy, as the new Macs either don't allow for future upgrades, or if they do, it's logistically difficult and prohibitively expensive.
First, here are our general recommendations for consumers: 512 GB is sufficient for general use. 256 GB is fine, but only for very light use (email and web surfing). 128 GB is useless as there is not enough space for system files, apps, and other things -- you will run out fast. Professional use is a different thing, and often times much more storage will be needed.
To determine how much space you will need, first do a backup, and then see the previous article on how to clean up your drive. Then, go back up to the Apple in the upper left and click About This Mac, then select the Storage tab. It will tell you how much data you are using. Write this number down. This is a good place to start.
Remember that as the years pass, file sizes will increase, so the more storage you purchase now, you are looking at extending the useful life of your new Mac. And you also need about 10% of the drive to remain free so that the operating system and apps have a place to work.
