Intego Mac Podcast, Episode 27: How to Sell Your Old Mac, iPhone, or iPad

In this week’s episode, we explain why you may see dialogs on your Mac warning that your apps aren’t compatible. Then we welcome Brian Burke, the president of, to discuss the best way to sell your old Mac, iPhone, or iPad.

Check out the latest episode of The Intego Mac Podcast, which I co-host with Josh Long. We talk about Macs and iOS devices, and how to keep them secure.

Understanding Compressed Files and Apple’s Archive Utility

Compressed files and archives are very common. You certainly see these files often—they bear the .zip extension, and contain one or more files that have been shrunk to save space. Archives also allow you to store a number of files in a single file, making them easier to move around or send to others. (For instance, if you sent a hundred text files to someone by email without compressing them, it would be very annoying to receive that many attachments.)

Apple’s macOS uses Archive Utility, a small app hidden away in an obscure folder and used to create and decompress .zip files. The Archive Utility app has some options that may make working with archives easier. In this article, you’ll learn about compressed files and Archive Utility, and we’ll show you some options you can adjust that will make working with compressed files easier.

How to Find Which Apps on Your Mac Are 32-Bit

Apple has been warning developers for some time that 32-bit apps would be deprecated on macOS, as they have already been on iOS. macOS High Sierra is now displaying a warning whenever you launch a 32-bit app, informing you that the app is “not optimized for your Mac.”

Not optimized
If you click OK, the app will launch, and if you click Learn More, you’ll be taken to an Apple technical document explaining this change. You can continue to use these 32-bit apps, and, as Apple says, “Using 32-bit software has no adverse effects on your data or your computer.” However:

The 64-bit transition for macOS and macOS apps is still underway, so final transition dates have not yet been established. But now is a good time to check with the software developer to see if 64-bit versions of your favorite titles are available.

So it’s a good time to check if the apps you depend on have updates available.

There’s an easy way to find all the apps on your Mac that are 32-bit. Choose the Apple Menu > About this Mac, then click System Report. In the System Information app that displays, click Applications in the Software section, and you’ll see a list of apps. Click the 64-Bit header to sort by No or Yes. You’ll see a number of apps, including some by Apple.

Again, there’s nothing to worry about right away, but it’s a good idea to check if the apps you use have been updated. Many apps automatically check for updates, but not all; for example, my ScanSnap scanner software does not do this, so I had to go find a new version on the vendor’s website.

Apple System Migration Guide for macOS Server

Apple recently announced that macOS Server would be changing, “focus more on management of computers, devices, and storage on your network.” But for many people who depend on macOS Server, this will be problematic.

Apple recently released a macOS Server Service Migration Guide that is:

designed to assist those administrators comfortable with installing and maintaining open source projects to migrate their service data to the underlying open source project that was previously bundled with macOS Server.

This guide essentially tells system administrators how to install software that will replicate the features that will be removed from macOS Server. It’s a lot of heavy lifting, but if you depend on Server, you should either read this and prepare for the changes, or not update (but, of course, that’s not a viable long-term solution).
