I first became aware of Apple products while employed as a trade coordinator at the Chicago Stock Exchange in 1980. A coworker never stopped talking about his Apple II personal computer. Interestingly, his last name was Mack. No one at the stock exchange used Macs,…  more

My background is in art and photography. Easy segue into computers. My first device was an Amiga computer, as I loved games. Got my first Apple product, the SSI, and finally found “home”. Have been an Apple lover ever since. …  more

…except Mr. Mack. I owned a Radio Shack TRS-80 at the time.

While living in Phoenix, I sold computer systems for CompUSA. Toshiba laptops were a hot item at the time; they now make excellent brick-like paperweights. I sold a ton of those machines to the medical community. One of my most powerful memories was watching a two-year-old girl who had been left alone in a shopping cart navigate through the operating system of a Mac desktop. It would have made a great Apple commercial.

I work for the Los Angeles Unified School District as a special education teacher. I have been in various positions for the past 18 years. Many teachers use Macs.

I purchased a black MacBook Pro in 2006. That machine served me well for many years. I also purchased a Mac Mini in 2006. It ran perfectly and never gave me a problem. My current machines are a 2020 iPad Pro with the Magic Keyboard, an iPad 2 that is obsolete, a 2013 MacBook Pro with 16GB RAM and a 512 GB SSD HD that I use as a desktop computer plugged into an Asus 4K 28’ monitor, and a HomePod that delivers great sound.

Apple has avoided allowing its products to turn into commodities by building superior products and matching those products with excellent customer service.

Our sponsor is Di-No Computer. Di-No is a premier seller of Apple products and provides excellent customer service.

The San Gabriel Valley Apple Users Group represents a wide array of experience and knowledge of all things Apple.

Ron Streicher

…public radio station in LA. That avocation subsequently evolved into a career that now spans nearly five decades as an independent audio consultant and recording engineer specializing in live performances.

He became a Macintosh user in 1987, at first just for writing magazine articles and his book — The New Stereo Soundbook — which is now in its third edition and has gained worldwide recognition as a standard reference on the subject of stereophonic perception, recording, and reproduction techniques.

By 1990, Ron was deeply involved with audio recording and production on the Mac and has been creating recordings for commercial and broadcast release ever since. He also uses his several Mac computers for designing audio equipment and preparing Keynote presentations for various technical societies and the Los Angeles Opera Community Educators Program.

A Fellow and Life Member of the Audio Engineering Society, Ron served as AES Secretary from 1991-2002, as President in 2003/4, and was re-elected as Secretary in 2012. He continues to be actively involved with its educational activities and has given numerous presentations to AES meetings throughout the world. In recognition of his long-term service to the Society, Ron was awarded the AES Bronze Medal in 1995 and the Distinguished Service Medal in 2010.

Mo! Langdon

I stumbled into Macs quite by accident.

I had just started working for my sister at a management consulting concern, doing various UNIX system admin and reporting tasks. One of the consultants was giving a presentation the next day, and handed my sister a bunch of changes for the org chart she was working on for him. She was far too busy to even think about the thing, so she sat me down in front of a chunky white box with a tiny black and white screen, and said: “This is our Mac (an SE) and this is SuperPaint. Here’s how you make lines; here’s how you make boxes; here’s how you do text inside the boxes; here’s the print of the chart so far and the sheets of paper with the changes and additions. Have at it!”

And that was the sum total of my introduction to the Mac. It’s been all downhill from there!

Sean McKinley

He was required to take a class that used a DOS-based program called First Choice. He also had a Cold Type class that used a code-based typesetting program and a Windows 3.1 version of PageMaker.

Sean’s first Macintosh was one of the last Mac Pluses bought from Personal Support Computers on Santa Monica Blvd., for around $799.00. Other Macs he has owned are the Macintosh 6100av, 12″ PowerBook G4, and an Intel Mac mini.

Sean has worked in the film and television business as a performer and in Entreatment Services, conducting surveys for the studios and on-screen advertisers. Like everywhere else in the world, the Internet is changing the way the entertainment business communicates. His clients now are more likely to send him an e-mail than call him on the phone. Paperwork is now downloaded from the Web instead of sent by courier service. Information that once was phoned in and sent by mail is now most likely entered online, or sent by fax.
