INSTALLING MLAB

You are about to get the downladable copy of MLAB for Intel Macintoshes running OSX (mac-mini, mac-pro, etc.) is available at www.civilized.com. This file is called mlabi.zip and it is 1106543 bytes in size. It should take about a minute to download. (If you wanted MLAB for an older OSX ppc Mac or an OS 9/8/7 Mac, go back and visit the download web-page for those systems.)

Before you download MLAB for an OSX Intel-Mac, you will want to look at the short Introduction to using MLAB found at www.civilized.com (You should print a copy for later reference.)

The version of MLAB you will obtain is the complete program with an expiration date. After you pay for it and register it, it will then have an unlimited lifetime. On-line help about MLAB functions and commands is available (by typing "help" in MLAB), and there are three MLAB manuals that will be shipped to you by mail when you buy MLAB. You may also download the manuals in PDF format from www.civilized.com.

When you click in your web-browser to download the OSX-native Intel-Macintosh MLAB program, a Macintosh archive file called mlabi.zip will be downloaded to your computer. Using the Safari browser, the default location of this file on your computer will probably be the directory /Users/[your user name]/Downloads/. (A directory is usually called a 'folder' in Macintosh parlance.) This is NOT an appropriate place. You should reset the download dirctory to be /Users/[your user name]/Desktop/; this is your "desktop"; all its contents will have corresponding icons appearing in the screen.

However, you can also copy or move the mlabi.zip file into your desktop directory after you download it. After the file mlabi.zip is placed in your desktop directory, the file mlabi.zip should show on your "desktop" with a zip-file icon.

Note, if you have your browser preferences set to automatically "open" downloaded files, then your browser will run the BOMarchivehelper program to "unpack" the mlabi.zip file. However, this will NOT work in later OSX systems if your "security preferences" for installing software are not changed from the default! And, even if your "security preferences" allow installation to proceed, this installation will go in the wrong place unless your downloaded mlabi.zip file is in your desktop directory.

Therefore you should turn off the option in your browser to automatically "open" downloaded files. (However, if you do successfully "open" mlabi.zip and create the directory 'mlab' in some inappropriate directory, you can manually move that entire directory to /Users/[your user name]/Desktop/, where it should be placed.)

After having downloaded the file mlabi.zip and placed it in your desktop directory, /Users/[your user name]/Desktop/, you will want to create the directory 'mlab' in your desktop directory and "unpack" the mlab files into that directory. All of this is done by double clicking on the mlabi.zip file showing on your desktop to run the associated BOMarchivehelper program to do this. However, on newer OSX systems, this will NOT work!

On some systems (i.e. Macintosh OSX 10.7 (Lion) and later), you will need to change the default "security preferences" in order to unzip the mlabi.zip file and subsequently run the MLAB program, mlab. This is required because Apple has included security features in later operating systems that, by default, prevent programs from being installed and run that have not paid a fee to Apple to register their software with Apple.

Changing your "security preferences" is done by clicking on the Apple icon at the top left corner of the screen, and then selecting System Preferences->Security & Privacy->General. Then select the radio button labelled 'Anywhere' in the window that has appeared. After you have allowed installation of software from "Anywhere", you may successfully install and run MLAB by double clicking on the mlabi.zip file icon.

The BOMarchivehelper program will create the 'mlab' directory in your desktop directory and place the various files of the MLAB system inside it. A new "folder" icon will appear on the screen representing this new 'mlab' directory.

You can discard the mlabi.zip file after the mlab directory is present.

To run MLAB, double click on the mlab directory icon on your desktop. The contents of this directory will be displayed. Now, double click on the MLAB executable file, mlab, within the mlab directory to run MLAB. (Later you will want to create an "alias" for MLAB on your "desktop" in order to easily run MLAB with one double-click. Directions for doing this are given in the intelmac.readme document.)

Before you run MLAB, it is important(!) that you print out the file intelmac.readme found in the MLAB directory on your desktop after your installation is complete. (The file intelmac.readme contains the information given here, plus more.) This file intelmac.readme contains further installation directions, plus other important information on using MLAB, such as how to 'navigate' the initial registration request, etc.
