Dennis installed the OS X Yosemite beta on a separate hard drive, which has been working great. Now he wants to make a bootable image of his current Mavericks installation to a USB key. Leo says OS X has a boot manager built in, so he can hold down the option key while booting up and choose which operating system he wants to start up in.
Ooma needs a new computer and she's heard that Quickbooks and Excel doesn't work well on Mac. Leo says that there is a Mac version of Excel, and there is an online version of Quickbooks, but it's better to use in Windows. Will Windows 7 be supported for awhile, Leo says yes. Microsoft will support it until at least 2020 for extended support, but Microsoft will end mainstream support in January 2015. But security wise, they will support it through 2020. Leo also says this is why Microsoft is pushing Windows 8 hard. And Windows 9 is next year. But Ooma has until 2020 to change OS.
Jeff is looking to get a MacBook Pro for college and he's wondering if there's a difference between the dual core and quad core processors. Leo says that quad core is more about speeding up rendering times than anything else. The higher end 15" model uses an NVidia Iris Pro GPU, which would be a more noticeable difference from the lower end models.
Bob has a MacBook Pro from 2011 and wants to know if there's a new model coming out. Leo says that 2011 MacBook Pros were subject to a recall, so Bob should check that out first.
Should he upgrade his computer with an SSD? Leo says that's a good idea and he advises getting the Mercury SSD from MacSales.com. They're 1 to 1 compatible with the Mac. He should make sure his SATA Bus is fast enough, though.
Kathy thinks she got hacked. She gave a support line remote access to her MAC and she's worried she got hacked. Leo says that if she didn't give them her credit card, chances are she's OK. But if you want to be sure, download Little Snitch. It'll observe your computer activity and let you know if it does phone home or let someone access remote access again. And turn on your software firewall. It'll protect you as well. But Leo says she's probably OK.
Marie had someone set up her router, and she needs to get the Wi-Fi password to set up a new printer. Leo recommends taping a piece of paper with the Wi-Fi password to the router next time so she won't forget or lose it. She can reset the router by powering the router down or unplugging it, then pressing and holding the little reset button for about 10 seconds, then when she starts it back up she can configure the router. But this would require her to set up a new password and reset all of the devices connected to it.
Ted is looking to replace his hard drive in his MacBook Pro. Leo has done that with all his laptops, replacing them with SSDs. It can be a challenge to replace the hard drive, depending on what model MacBook Pro he has. The modern MacBook Pros are a bit easier, although the screws are tiny and of difference lengths. Once he has opened it up, replacing the hard drive is pretty straight forward.
Microsoft pioneered public beta tests of operating systems, but once it expired, you would have to reinstall it. Apple gives away OS X, so there's been little incentive to get people to try it. Leo says that the new look of OS X is flat and the features are very good. Should you install it? It's safe to install, and it's very mature, but Leo's in no hurry.
For the first time in a long time, Apple has released a public beta of its next Mac operating system: OS X Yosemite.
OS X Yosemite public beta arrives (Macworld)…
John has a Mac Mini with a USB hub, but he can't charge his iPad with it. Leo says that the iPad requires 10 watts to power and re-charge it. Standard USB ports have about 5 volts, but the amperage varies. Apple broke the standard for charging with the iPad. The older ports won't charge iPads because they don't get 10w or power. Apple's own chargers work fine, and if he has a late model iPad Air, he should be able to. But for now, get an 11w charger and that'll do the job.
