" Here's an article with some helpful tips (they refer to them as 'hacks') for your Mac," Jim Hamm introduces his latest email to us. "You may already be knowledgeable of these tips, but a new one (to me) I just tried was the terminal command 'purge' to free up memory. I'm not sure what it exactly did, but the command definitely freed up memory on my MacBook Air and my apps and music kept right on running.

"My 'Air' only has 4GB of memory, and free memory tends to disappear after using my Air for awhile, so this tip is helpful and quick to use. The article refers to a video wherein the author mentions a free App from the App Store titled 'FreeMemory,' which purportedly does the same thing. The app gets good ratings in the App Store."

(And if you come to PMUG on Saturday you can chat with Jim. He's the speaker this month.)
