APP REVIEW: Limbo

What image do you have behind the login menu when you start up? Classically, depending on the exact version of Mac OS X you are using, you have one of the “universe” images. This image can be replaced on your system with a picture of your choice. To replace the image you see as the default desktop behind the login window, find a .jpg file that you want for your new back round.

Duplicate the image, preferably an image the same resolution as your machine default display resolution, and name the new file “DefaultDesktop.” Open a new finder window and navigate to *(NameofyourHD) > System > Library > CoreServices.* Drag and drop your new DefaultDesktop image into the Core Services folder.

When you release, you will be asked if you want to replace the existing file first and then to authenticate as an Admin User secondarily. The next time you restart and before you log in, you will see that image behind the login window.

I was at a customer’s office the other day helping to set up their new Mac system. It was a busy construction company and they needed help getting wireless scanning operational. I noticed that they were using Adobe Reader for their PDF files, so I introduced them to “*Preview*”:https://support.apple.com/en-us/HT201740. Once I set the Finder to open PDF files with Preview instead of Reader, I showed them how to access the scanner to scan documents right from Preview.

As I had them practice this, I noticed that much of their scanning needs were for documents that they would print out, sign, scan and then email to clients. When I showed them how to use the “signature” function in Preview they immediately saw the value and time saved. So, I know many of you already know how to use this tool, but I thought I would go over it so you too can use your electronic signature.

Preview is used to view and edit PDFs and images, import images from a camera, import documents and images from a scanner, add pages to a PDF and also to take screen shots. When you have a PDF that needs your signature, the old way of doing this would be to print out the PDF, sign it, scan it and send it back. With Preview you can skip some of that work. You can capture your signature using your trackpad or better yet, using your camera on your Mac.

! Annotate > Signature > Manage Signatures*. When you select *Create Signature* you have a choice of trackpad or camera. While signing on your trackpad is okay, I prefer the camera method. Here you take a white piece of paper and sign it. Then click on *Camera* as the means of capturing your signature and hold up that piece of paper to the camera on your Mac. Once you align the signature on the blue line you can hit *Done* and your signature is stored. If you don’t like the first try, click *Clear* and do over.

To add your signature to a PDF document click on the *Sign* button !http://blog.smalldog.com/images/4295.png! or use the path *Tools > Annotate > Signature* to select the signature. Once it has been placed on the document you can drag it to where you want it, then use the handles to adjust its size. Save the document and you can include it in an email with your signature. Remember that the *Save As* command is sort of hidden now but to get to it simply hold down the *Option key* when you select *File.*

Working at the Service Check-in Counter, I often have customers asking me how to get out of Zoom and/or Voiceover on their iOS devices. While most people have Zoom and Voiceover disabled, it still shows up now and again.

If you have used Zoom, the image to the right may seem familiar. If this happens, you can try to enter your passcode and navigate to Settings to turn off Zoom but this can be difficult. An easier way out is a simple 3 finger tap twice which will Zoom you back out.

If you have seen the image above, then you also must have experienced Voiceover. Instead of using your finger to select individual apps, the screen is sectioned into rectangles, and you select that shape as whole. It is very hard to navigate, and the whole time a voice is instructing your movement. Voiceover is helpful for the visually impaired, but can be a hinderance if turned on. You must navigate back to Settings > Accessibility and turn Voiceover off if you do not wish to use it. If you have the shortcut enabled, you can try triple clicking the home button. This will turn off Voiceover. I would recommend turning off both Zoom and Voiceover, unless of course you need them and are familiar with their commands.

I love Lion. So far it is my favorite iteration of Mac OS X, but it does have some annoying features. In my internet wanderings yesterday I came across an article with instructions on how to get rid of the rubber-band effect which occurs when you scroll to the very bottom or top of a page. This effect will make the page scroll a little bit past the end point then bounce back. It’s a nice little bit of eye-candy, but not really necessary.

You can easily turn this effect off by entering a simple Terminal command (which I’ll list below) and then press “enter”. As always, do this at your own risk. Mucking about in Terminal can cause irreparable harm to your OS if you do something you shouldn’t. Make sure you have a good backup before you make any changes like this to your system. Here’s the text you need to enter:

defaults write -g NSScrollViewRubberbanding -int 0

You can revert to the original setting by entering the following and then press enter:

defaults delete -g NSScrollViewRubberbanding

You’ll need to relaunch any applications that display the rubber-banding in order for this to take effect. Unfortunately, it will not affect Safari. Should I find a way to get rid of the rubber-band in Safari, I’ll update this article.

2014 marks the 30th anniversary of the most important technological development of all time: Tetris. There are probably many of you out there that will insist that the Macintosh computer was the most important tech release of 1984, and I will grant that it is a close second, but I am still standing behind the classic tile-matching puzzle video game.

For those of you who don’t know, Tetris is a very simple game in which any of seven different blocks, which are every possible combination of four smaller square blocks that have adjoining sides, fall from above and your job is to move them side-to-side and/or rotate them in order to complete horizontal lines which disappear when completed. The ultimate move is to leave only one vertical line incomplete and drop the “line” piece in to complete four horizontal lines at once. This is a Tetris and you will be rewarded with big points, flashing graphics, sound effects, and the satisfaction of a job well done.

Tetris was originally developed by Alexey Pajitnov in the Soviet Union, and was the first video game exported from the USSR to the US. Its popularity skyrocketed when a version was released for the Nintendo GameBoy in 1989, and versions have since been released for just about every console, operating system, personal electronic device, and has even been played by using the windows in a large building as the blocks.

While the 8-bit NES version will always be my favorite, I have been playing a new version on my iPhone: “*Tetris Blitz by Electronic Arts.*”:https://itunes.apple.com/us/app/tetris-blitz/id632827808?mt=8&at=11lb7k This version takes the classic gameplay and condenses it into a two-minute speed round in which the goal is to score maximum points. They have added a number of power-up blocks which trigger different actions, such as lasers that burn up several lines for you or masses of blocks that drop all at once. You can play in single player mode, head-to-head against strangers or your Facebook friends, as well as in special tournaments which often have different rules or game mechanics for added variety. This app is free, but employs what has come to be known as the freemium model, which means that there are a fair number of in-app ads and in-app purchases that are available. If you can learn to ignore these, this app is a fun addition to the Tetris family and only -wastes- uses two minutes at a time.

The best part? Tetris is good for you! According to research, playing half-an-hour a day for three months boosts general cognitive functions such as critical thinking, reasoning, language and processing and increases cerebral cortex thickness. It has also been shown to be a potential therapy for preventing PTSD as well as a way to help quit smoking. “*See here for more information.*”:http://en.wikipedia.org/wiki/Tetris#Effect_of_Tetris_on_the_brain
