Apple

It could be a hardware issue, or a driver issue. It's much more likely that this is a hardware problem, though. The first thing he could try is clearing the "PRAM". Restart the Mac by holding Command, Option, P, and R.

He can also try booting from his system disc. If that works, then he'll know that his logic board is failing and that's an expensive repair. Hopefully Alex has AppleCare. Otherwise, it may be more worth it to just get a new Macbook.

Leo says it's not necessary. No app really has an exit button because the mobile device actually releases the program from memory and exits automatically. He's wondering about the app still taking up CPU cycles in the background, though. Then, Leo says, the app isn't properly coded. The app should clean up after itself.

It's probably because the drive has run out of room. Remember that Time Machine keeps multiple backups, so Kathy may just need to delete an old backup or get a larger hard drive.

She's also getting an error that says the drive is read only. Leo says that he's gotten that message as well. If she did a hard shut down, that may cause the read only error to occur. She should try and repair permissions first. It's possible that Kathy will have to start over and rebuild her backup from scratch, though.

Paul's wife got him a new iMac for his birthday and he's worried because he keeps hearing an update is "imminent." Leo says so what? The rumor sites are making up dates and pushing the meme that updates will happen any minute. The truth is, it could happen tomorrow, or it could happen next year. So we don't really know.

Leo recommends the iPad. It won't have the hassles that the desktop computers have. If he also needs internet connectivity, he can just get the LTE iPad and the internet access will cost less than most home internet options.

Yes, but there aren't many choices. She could change the voice to the British version, which is a male voice. Or the Australian voice, which is just another female voice with an accent.

Leo says they are doing that with the iPad. But since Apple is selling 3 different models of iPhone, they need to differentiate them somehow.

Nearly every rumor about iPhone 5 was true, and this is either because Apple can't keep secrets anymore, or it's because Apple is manufacturing them earlier and secrets are coming out of the factories. We haven't heard anything about the next iPhone yet, but Leo says we should know a lot more come spring next year.

Leo predicts the next iPhone will look exactly the same as this one, except it may have upgraded internal components. Smartphones have reached maturity, and there's really nothing more Apple can do with it. It is what it is.
