Ron bought a MacBook Pro. It's his first Mac. It was working great and then a month later, he started getting error messages and crashes. He backed it up and took it to the Apple Store to have it looked at. It came back without Bootcamp on it and they never figured out what was wrong after several trips back. Leo had a similar problem with his Mac Pro and they discovered it was bad RAM. It sounds like Ron's problem could be similar. It could also be the the hard drive.
We talked last week about a flaw in iOS and OS X Mavericks called "Goto Fail" that would allow a malicious user to intercept the traffic of any secure transaction. Apple patched the bug on iOS with iOS 7.0.6 quickly, and just earlier this week they patched Mac OS X Mavericks. Make sure to update both iOS and OS X so that your computers and mobile devices are secure.
Conrad has a Mac and he's having trouble with his hybrid hard drive. He's tried formatting and partitioning it using Disk Utility and he gets an "can't allocate memory" error. Leo says it sounds like a bad hybrid drive. The fact that it's a hybrid drive shouldn't matter because the hybrid part is handled internally by the drive circuitry. It should appear as a single drive to Mac OS X.
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.
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.
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 is thinking of getting either the 13" MacBook Air or the 13" MacBook Pro. He also wants to get an external drive. The 13" MacBook Air has far better battery life, but the MacBook Pro has a much better retina display. So it really comes down to what he wants most. The MacBook Pro also comes with a 256 GB SSD. Leo says he should only use an external hard drive if he finds he's running out of space on the laptop. It's best to keep what he can on the internal drive, so he doesn't need to always rely on having an external drive plugged in.
Chris is still having issues with OS X Mavericks and wonders if upgrading to 8GB of RAM would help it's performance. Leo says not really unless he's doing video or photo editing. If the Mac is running slow, it won't hurt to double the RAM. 8GB is a bit of a sweet spot, though, and it could help if he's having performance issues with the OS. But the real issue could be Mavericks itself. It's filled with bugs and Apple needs to fix it. The chatroom also says to go into the activity monitor and view his RAM usage. That could show him where the issue really lies.
Robert has finally saved up enough money to get a Mac, but he noticed he has to install Flash himself. Leo says that Steve Jobs hated Flash and as such, Apple stopped supporting it. Leo says he can download and install Flash from Get.Adobe.com/flashplayer. He should just make sure he gets it from the official site, and not a phoney one. He should also be careful not to fall for the scam that he needs a new version of Flash to watch a video. Download Flash from Adobe directly and install it.
