Tim has a Mac and every once in awhile he has to run Disk Utility to repair permissions when it runs a little crazy. But it happens quite often. Leo sometimes thinks it's "voodoo" to have to run it, but repairing disk permissions is usually the best thing to do when the Mac starts to act up. What it usually reflects is that the metadata can get corrupted, preventing the computer to write to it. Repairing the permissions fixes that.
Mike is trying to use Windows 10 on his iMac with a Fusion drive and it won't take. Leo says that the Fusion drive causes issues with Windows 10. The key is to get the drivers from Apple. Mike tried those and they wouldn't load. Leo says that points to either a bad ISO download or a bad driver download. He should start over. Download the ISO and the drivers again and see if his luck improves. He'll also need the 64 bit version of Windows 10 to run in Boot Camp, and his Mac needs to be a late 2012 or newer.
Richard has a friend who's Mac is running slower. Is that because her machine is getting older? Leo says maybe, but it may also be that her hard drive is getting less reliable. As the hard drive gets older, it starts to have to work harder to process data. It begins to cache data more. So replacing the hard drive, especially with an Solid State Drive, can make a world of difference in speed. Updating your OS can also help, though if it's too old, you may not upgrade to the latest (El Capitan). Leo says there's a few easy things to do like resetting your browser and clearing the cache.
Ronnie has an iMac that runs OS X Lion and he's stuck with it, according to a salesman at Apple. They said it won't run El Capitan. Leo says that the retail guy is wrong! Apple offers a free upgrade for Lion. What he may be talking about is that if he erases the hard drive, he can install the OS over the air by downloading and installing. In that case, it will download the OS that came with the Mac. But then he could upgrade for free. A ten year old Mac can upgrade to El Capitan.
CMD + F1 will is the keyboard shortcut to mirror the Mac display to an external display. If he's using a Windows keyboard, he'll need to press the Windows key + F1.
James is thinking of getting a used Mac Mini. How can he find out how old the Mac is? Leo says to check out EveryMac. It will give him a list of specs for it. He shouldn't go back further than 2012, though. He'll want to use the latest version of OS X, El Capitan, so he'll want to make sure the machine can support it.
Henry wants to buy a new Mac and wants to know if it's true that processor speed isn't as important as hard drive speed. Leo says that's true. Processors are really fast now and there's only a dimes worth of difference between them for every day use. It's better to get an i5 and then spend more money on a faster hard drive and better screen. Leo says that a 21" iMac with an SSD is best for speed, but a Fusion Drive would give him more space plus a speed boost.
Joseph has an old Mac and he has tons of videos, music, and other stuff on it. He's deleted a lot of it. But he still has over 172GB of files he can't find. How can he get rid of them? Leo says to download Disc Inventory X. It will show him what and where those files are and will help him get rid of them.
Dale has an old Mac Pro and when he upgrades, he wants to be able to connect the drives to his new Mac. Leo says that the Mac Pro will soon get Thunderbolt 3 and it will be really fast. And the 5k iMac is amazing. Thunderbolt will allow him to daisy chain his devices with external boxes and optical drives. He should check out OtherWorldComputing at MacSales.com.
Mike wants to put Windows on his Mac and wants to know how he should format his drive. Leo says that exFAT is a good option because it can go bigger than 4GB per file and Mac supports it. But Leo just uses FAT32. exFAT is also optimized for Flash, so it works great on USB keys.
