How can I get wireless printing to work with my HP printer?

Add Printer in OS X

Episode 1088

Mike from Denver, CO

Mike has an old HP printer and he wants to use the wireless printing option. It works great wired, but he has issues printing through Wi-Fi. It says his printer isn't connected. How can he get the computer to recognize the printer?

Leo says that he'll have to go into the printer settings and tell it what the Wi-Fi access point is. He should remove the USB connection and have it rediscover the printer. Uninstall everything first and then press "plus" in the Printer section of OS X's settings, and he should be able to add it.

Can I put OS X Mavericks on my 2007 MacBook Pro?

Episode 1058

Aurelia from Riverside, CA

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.

How can I turn off hibernation on my Mac?

Episode 1035

Luca from California

Luca's Mac goes to sleep and goes into hibernate mode. Is that normal? Leo says it is and he can't turn off hibernate anymore in OS X. Will it hurt anything? Leo says not at all. It's designed that way. The sleeping computer refreshes the RAM and still checks his mail, syncs to his calendar, etc.

According to the chatroom, he can turn it off with a terminal command. Check out this Apple forum post for more info.

How can I stream my pictures to my Apple TV?

Episode 1033

Bernie from Lakewood, CO

Bernie has a bunch of old slides that he transferred to DVD, and then ripped them to his Network Attached Storage, along with image files of discs (ISOs). How can he view them on his network? Leo says that VLC is an amazing video product that will allow him to view it.

What about Apple TV? Leo says no, it can't understand ISOs. But Bernie can use his Mac with Mountain Lion or later to airplay them to Apple TV. He can just open the ISO with a Mac program like Disc Utility and then once it's mounted, he can stream it from the Mac using AirPlay.

Should I switch to an iMac?

Episode 1018

Jackie from New York, NY

Jackie is considering making "the switch" to an iMac. Leo says he prefers the Mac, but there's really not that much difference now between Mac and Windows. It's largely a matter of taste. Buy business grade hardware and it'll last. Not all PCs are business grade - a lot of them are low quality consumer grade computers at low cost.

Why can't I get CDs from my doctor to play on my Mac?

Episode 1007

Jane from San Diego, CA

Jane has a three year old MacBook running Snow Leopard, and CDs she gets from her doctors won't run on it. Leo says that Jane should make sure it's a CD, not a DVD. It may be that her drive doesn't support DVDs, just CDs. Leo says that the program needed was called "Rosetta," and that's an old emulator program designed to run older, proprietary software. Leo says Jane doesn't want to install that because OSX has moved beyond it. Leo recommends asking the doctor to install a program that works with modern Macs.
