Is Your Mac Still Running OS X Lion? Why? You Should Upgrade to OS X Mavericks

It’s fairly common for computer users to delay updating to major operating system releases, and though Mac owners tend to be a bit better at upgrading than Windows users, many are still running old versions of OS X. For some users there are good reasons for this, maybe lingering on outdated OS X versions like Snow Leopard because of compatibility issues with a specific app, or because they just really like it. But then there are other users who have already made the leap beyond Snow Leopard, and are sitting on OS X Lion or OS X Mountain Lion, procrastinating and putting off the OS X Mavericks update for no good reason. This article is aimed at the procrastinators (and there’s a surprisingly large amount of them – nearly 17% of Mac users are on Lion and another 20% on Mountain Lion), particularly individuals with Macs still running OS X Lion, in any version from 10.7 through 10.7.5.

Some Mac users may encounter an apparently random disappearance of Bluetooth functionality, often after rebooting or updating Mac OS X. The first obvious indicator is that no Bluetooth hardware works, be it a keyboard, mouse, headset, or otherwise, and when attempting to visit the Bluetooth menu of Mac OS X a “Bluetooth: Not Available” error is displayed while the menu bar items icon has a squiggly strike through it.


Ever wanted to create an iPhone or Android ringtone from an existing audio file, but wanted to complete the process entirely from the command line? You’re in luck, because Mac OS X has a little audio conversion tool that can turn any existing audio track into an Android or iPhone compatible ringtone in seconds. We’ll break the command down for both Android and iPhone users, though whichever method you choose you’ll still need to sync the ringtone over to the device yourself.

The powerful curl command line tool can be used to download files from just about any remote server. Longtime command line users know this can be useful for a wide variety of situations, but to keep things simple, many will find that downloading a file with curl can often be a quicker alternative to using a web browser or FTP client from the GUI side of Mac OS X (or linux). This is is helpful for local situations, but there’s particular value if you’re in a situation where you need to download something to a remote Mac when connected through
iPhone and iPad users have the option to enable a “Do Not Track” setting on their iOS devices for Safari, a feature that is aimed at limiting targeting and tracking of web browsing behavior by various web services. When turned on, this causes Safari to make a DNT request to each page it visits for any services on that page to not track the client, though that doesn’t necessary mean it will he honored, as we’ll explain shortly. Nonetheless, users who favor privacy may want to enable the option anyway, even if the efficacy may be more limited when compared to
If you’ve ever joined a public wi-fi network and noticed the Finder sidebar is suddenly filled with other unfamiliar computers and network shares, and then curiously clicked on one of them, you’ve probably discovered that most of these computers have a user ‘Public Folder’ accessible to you and everyone else. This folder is included with every user account in OS X, and it has very limited access which is designed to facilitate simple file sharing (it does quite well), but such a feature may become undesirable on public networks with many foreign computers. Turning off your own Mac sharing Public Folder is quite simple, and it will prevent other Mac users from having access to the ~/Public directory if they’re on the same network.

The optional iOS Restrictions settings provides a way to limit access to adult themed websites from Safari on an iPhone, iPad, or iPod touch, but for some purposes those default restrictions may not go far enough. For those looking to gain additional control over web access, users will find that individual websites can be added to a “Never Allow” list, thereby blocking access to those sites completely. For example, Facebook.com is typically allowed in the broader iOS Restrictions filters, but by using this additional block list, you could prevent web access to sites like Facebook.com, or any other URL, from the iPhone, iPod itouch, or iPad.
