Bird has 15 Macs at work that he has to set up. He wants to know if he can do a net install to create a setup when connecting the Mac to the network? Leo says that Apple has a Net Install option through the System Image Utility. It's a simple google search. There's also a company called JAMPH that can do it for you. They are the leaders in network Mac management.
Jim bought a new Mac and wants to know how he can set it up like his old one. Leo says he'll need a cable and connect the two. There is a tool in MacOS that will copy everything over and make it look just like the old Mac, only faster. Leo does recommend, though, to take an external hard drive and backup data just in case. Leo recommends either SuperDuper or ChronoSync. The old mac should also have someting called "target disc mode," which can be used as an external drive, dragging them over to the new mac. But Jim will probably need a thunderbolt-firewire adapter.
Mark's Mac Air is slowing down and he wants to know if there's an app like SpinRite that can run them. Leo says that sold state drives (SSDs) use TRIM, or wear leveling to keep your SSD in good shape. It doesn't need to be defragged directly. But it will trigger the controller to run the TRIM utility. Search for TRIM in macOS. But it should happen automatically. If your OS is older though, you may need a third-party app to do it.
TRIMFORCE Enable is the command you can use in the terminal. That could speed it up.
Mike wants to know if he can use more than one monitor on his computer. Leo says that most modern-day computers do support multiple monitors and both Windows and macOS support it natively. But the computer has to have more than one display port or HDMI port to do it. Most do out of the box these days.
George has an iMac, but it won't let him upgrade to Catalina. Leo says to go to the Apple Menu and look under System Preferences. There's an update feature there, so select the gear. It'll run the update check. He can also look for the compatibility checker here - https://www.apple.com/macos/catalina/.
Bill is an app developer for iOS and he's looking at using Project Catalyst to create them for the Mac as well. Leo says that it depends on the app, whether it makes sense to have a desktop app as well. So it depends on the app. But Leo says that developers are crazy for Catalyst, and it's Apple's "dog food" for writing their own apps in it. So if Apple is using it, it would make since to go that route.
Chuck is using Firefox and recently he's been getting error messages. Leo says that may be due to keeping a lot of tabs open. Should he go back to Safari? Leo says that it's about as good, privacy-wise, as Firefox. But for search, he's currently using StartPage.com for searching anonymously. Use that, and it's just as private as Firefox.
Bonnie got an invoice from her travel agent via email, which she was expecting, and now she's having issues. Leo says that's not wise to do because she should never open attachments. But she had to update her PDF reader, and that's when the problem started. She downloaded a suspect version of Reader.
Ray wants to know how he can update macOS without an internet connection? He has more than one computer and doesn't want to download the update more than once. Leo says that you can copy the installer and then use it on the other computer if you do it within an hour or two. It'll be up to date. What happens when a patch has multiple versions? Leo says that sometimes Apple slipstreams a fix into an existing patch, and users end up with two different versions. That can be confusing. But go with the most recent one.
Dan is shopping for a MacBook Air for his son's trip to China. but when you add more RAM, it's more than the MacBook Pro. So should he get a MacBook Pro instead? The MacBook Pro will have a faster processor and more storage, plus the size is about the same. So maybe the MacBook Pro will be a better option. Especially since it offers more storage for $500 less. It has the older butterfly keyboard, however, which could cause problems if eating while working. SO make sure to buy AppleCare plus.
