Terry is having problems booting up his Mac unless it's in safe mode. Leo says that it sounds like there's a corrupted kernel that is clobbering everything. He recommends backing up his data, wiping the drive and then reinstalling the OS and programs. The Mac makes it easy to do, too. If he bought his programs in the Mac App Store, he can just install all the apps he owns. Terry shouldn't install anything he doesn't need. It's better to just install as he goes. It's also an indication that his hard drive may be going bad, so it may be time to get a new drive.
Danny left his laptop on while flying and when he went to open the laptop, the drive disappeared and he doesn't know what happened. Leo says it sounds like the drive had been jostled to the point that the computer couldn't read it. It could still be connected, though. It's likely that the disk catalog was damaged or corrupted. He could run disk utility, but Leo isn't all that confident that it will work for him. Drive Rescue could perhaps fix the problem. Disk Warrior is another.
David can't highlight text in Excel or Word when he's in remote desktop with his Mac to his 64-bit Windows PC. Leo says that there may be an issue with the functions in remote desktop and he can verify that by trying with another PC. The Mac isn't using any resources, it's just a window. So there's something wrong with the 64-bit Windows PC that David's trying to access. Leo says that there's possibly bad rendering going on with Windows Remote Desktop. Alternatively, install Office for the Mac.
Al bought an old iMac G4 and wants to know if he can upgrade the software to Leopard. Leo says that the G4 is about 15 years old, and it may not support it because it's the old PowerPC chip. Leo recommends checking out EveryMac.com. He can look it up by serial number and it will tell him what software it can run. It's probably not going to be OS X.
Keith wants to know how strong his WiFi network is. Leo recommends WiFi Analyzer. For the Mac, there's WiFi Explorer. It will give him a line graph with signal strength according to channel. It's $20.
He can find other WiFi analyzer apps at netspotapp.com. It may be that all he needs to do is reset his WiFi settings.
Security experts found a piece of malware on the Mac which could have been around for years since it was written in an old Apple language called Pearl. Apple has immediately patched the problem, but Leo says a second version may still be active. The malware affects up to 90% of Mac users.
Sheila's TV died right after her warranty went out. They wanted several hundred dollars just to diagnose it. She can't even have a local place do it because they've gone out of business due to not getting any parts. Leo says the trend is now to make it albeit impossible to repair products, and there's a Right to Repair movement in many states to make repairability the law. But the sad fact is, in most cases a TV just isn't repairable or worth the money to fix. She'll be better off just getting a new one. However, Sheila's Samsung may be subject to recall.
Taking screenshots used to be something that would require a third party program. This was especially true if you wanted more sophisticated capabilities, like the ability to annotate screenshots. While there are still third party programs for doing this, many of these features have been integrated right into the Windows and Mac operating system. Here's how to make use of the screenshot features in Windows and Mac.
James says that on his Mac, Apple has taken away the color icons in the sidebar. Jason says that sometimes Apple just decides to break stuff because they know better, or it fits into their overall plans for the software — removing features while bringing in others.
Jason recommends checking out an application called DragThing. This would allow James to have a separate dock where he can put more applications. Then he can stop using the Finder sidebar for that.
Steven has an old MacBook Pro that has Windows 8.1 installed with Boot Camp. He'd like to dump Windows now and get that space back. Jason says he can open Boot Camp Assistant and click through to the partition utility and use it to remove the partition. He'll just need to click "restore." That will allow him to restore his Mac to its original configuration. Sometimes that doesn't work, though, so he can delete the Windows partition in Disk Utility as well.
