Leo bought a Mac Pro and it's a great machine, but it suffered from an intermittent problem. After hours on the phone with Apple Care, he finally gave it to his techs at Tech Guy Labs to troubleshoot. It turned out to be a bad memory module.
Users of all iDevices should update to iOS 7 immediately, as Apple just released an emergency update to prevent "man in the middle" attacks that could compromise your data. It's also a vulnerability with OS X, but a fix isn't out for that just yet.
John got an old Macintosh SE and he keeps going through hard drives. Where can he find more of them? Leo says that the hard drives he's using are old and used and just plain worn out, since the Mac SE is 30 years old. eBay may be a good way to find those. Leo also recommends EveryMac.com, and LowEndMac.com. Since it has an external SCSI port, Leo says that John could use a more modern drive with a SCSI interface. Then he could daisy chain it.
Aurelia has a 2007 MacBook Pro and wants to know if OS X Mavericks would work on it. Leo says it's right on the edge and it depends. It may actually come down to RAM. 2GB of RAM is a bit light. Even if it will install, it may be slower, not faster, and it would be difficult to go backwards. Apple's recommendations call for 2008 or later. Leo recommends going with Lion, but no later. It's really time to start saving up for a new Mac.
Mary's son upgraded her Mac to OS X Mavericks and now it's running slower. Leo says Mavericks has bugs, but slowing down the computer isn't one of them. Leo says it could also just be coincidental, and that the hard drive is starting to fail.

Joe's iPhone 5 is having issues with Messages. When he erases messages, it doesn't free up any of the space on his phone. Apple says it's a known bug.

Or, he can backup his phone to the cloud, then toggle documents and data to off, and then restore.
Jim is an amateur photographer who reviews his pictures on the camera to delete the ones he doesn't like. For Christmas, he got an iPad Mini, and would like to preview the images on his camera card. Leo says that the iPad Mini doesn't have a set file system like that. Jim understood that and returned it. Leo says Jim didn't have to do that, he could've gotten the camera connection kit which would allow him to plug in an SD card.
