Why can't my iMac read my SD cards?

27" iMac

Episode 1676

Vanessa from California

Vanessa has a two-year-old 27" iMac. She uses it for her drone photography editing, but her SD card adapters aren't reading. Leo suspects that the SD cards aren't reading because of the format they've been formatted in. It may be due to formatting the card in the drone itself.  Leo recommends Disc Utility on the Mac and format the card with ExFAT. Copy off the data first though with a Windows machine. Also, make sure you use a card that the Mac supports.

Why is my Mac crashing running macOS Catalina?

Catalina

Episode 1674

Charles from California

Charles has upgraded to macOS Catalina 15.1, and now he's getting crashing due to an error with an iOS device. Leo suspects it may be a wifi sync issue between Charles' iPad and the Mac. So into the music settings and turn off sync library and see if that solves the issue. It sounds like a bug that Apple has to fix. Also, try opening the Activity Monitor. It'll show what processes are running and when you shut down, kill the sync process. That's not a great solution long term, but it could work until the fix comes in a future update.  A complete clean install may also fix it.

Sean's wife has Mac she recently upgraded to Mojave, and after updating to a "new flash player," she's now having problems. First, her Safari browser has defaulted to the BING search engine. Leo says that BING isn't too bad, but it's clear her browser has been hijacked by a browser hijacker or "launch demon." And if her search engine has been changed, there's a good chance other things have happened as well. Check browser extensions to see if there's anything nefarious there.

Episode 1658

Rick from Torrance, CA

Rick has up to six copies of photos on his computer. How can he get rid of duplicates? Leo uses a "dedupe" program called Gemini 2, and it works on macOS and iOS. It's from MacPaw. It'll go through all your photos and figure out which image is a duplicate, which is an edited copy, and more. And for $20, it's worth it.

Rick also wants to know if he can turn an old laptop into a Chrome book. Leo says not strictly, but there is a company called NEVERWARE that has an app called CloudReady, which promises to turn your old laptop into a Chromebook.

Mac

Episode 1638

Jim from Santa Clarita, CA

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. 

Why is my Mac Air so slow?

Macbook Air

Episode 1636

Mark from Tustin, CA

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.
