Diane updated her iPhone 5S to iOS 8 and now it's not running properly. She clicks on one app and another one opens. Leo says that there's always the potential of something going wrong when updating an operating system. It's like trying to pull a table cloth out from under dishes and trying to put another table cloth in its place.
Steve's Samsung Galaxy S4 and the recent update has taken out a messaging feature he relies on. Leo says that often happens in an update. But it may also be something he can fix in the default applications menu. If that's not going to fix it, then Steve's only other option is to root his phone and put a custom OS like Cyanogen mod on it.
Brent has an Acer Iconia tablet and it's starting to freeze up when watching movies. Leo says if you can update it to the latest version of Android, that would be a good idea. Another idea would be to go into backup/reset settings and restore it to the original settings. Sometimes that helps with issues by starting from scratch. Just make sure you have enough space. Clear out the cache.
Abdiel is having trouble updating his Nexus Player to Android 5.1. He gets a red triangle error. Leo says that over the air updates require more storage because it will need to expand and install the update. So he may need to restore the player before he can update it. If that doesn't work, it's possible that the OTA download is bad. Google has released the 5.1 image for download, so he should try that. Abdiel will also need something called "Fast Boot" on his machine.
Dan has been getting messages to update Java, but he's worried about security. Leo says that since Dan uses Windows XP, there is a security issue because Microsoft doesn't support it anymore. Google will update Chrome, so it's a good idea to use that as his browser. But he shouldn't use Java unless he needs to. If he does need to use it, he should make sure he installs all security patches. He should disable the browser plugin as well, and he should run Windows as a limited user -- not as Administrator.
Tyler wants to know about the hack for Windows XP that will allow it to continue receiving updates. Leo says it involves altering Windows so that it think its "Windows Embedded for POS." It requires a registry hack, though, and Microsoft frowns on it.
Jerry began having Wi-Fi issues after updating drivers from HP. Leo suggests looking in the system tray to see if there's a red "x." If there is, then he'll know the problem is a connection. He should go through the settings, update his password, and make sure it's in Ad Hoc mode, not infrastructure. Right click on the tray icon and select "Properties." That'll take him to settings.
Another option is to roll back to the old drivers. Jerry can also go into the system BIOS and make sure Wi-Fi wasn't disabled there.
Edward is thinking about getting an Apple TV, but he doesn't see Apple really pushing it all that much. Should he wait for a new model? Leo says that it's not really that expensive at $99, so if he buys one and then Apple releases a new one, he's not really out all that much.
Apple released OS X Yosemite and iOS 8 earlier this month. While the new operating systems bring a lot of new features, it's always a wise idea to wait so that bugs can be fixed and apps can be updated for it. But how will you know if the apps you use have been updated for OS X Yosemite or iOS 8? Fortunately, there's a website that keeps track of it all -- RoaringApps.com.
Howard has a two year old 27" iMac and wants to know if he should upgrade to OS X Yosemite. Leo says not right away. There's no need to rush in as in the first week of a new OS roll out. There's always bugs that crop up. Howard should probably wait for the second update to Yosemite, which will fix whatever the new OS breaks. He'll know in the first week what problems crop up. Once Apple puts out a fix, and then a fix to fix the stuff broken in the fix, he'd be ok to upgrade. It'll probably take about a month.
