Apple released Yosemite 10.10.1 on Monday to fix Wi-Fi problems that hundreds of Mac owners had reported since the operating system was released last month. But for many, the update did nothing to restore connectivity, and for some 10.10.1 caused Wi-Fi problems where none existed before.
Macworld readers reported their own issues with the Yosemite update, reflecting the current sentiment over on Apple's support forums. A handfulofthreads on Apple's Yosemite support forum indicate that 10.10.1 didn't fix the problem of Wi-Fi connectivity dropping out, or if it did, Wi-Fi remains slow. Some users are resorting to Ethernet to get a connection.
The Wi-Fi problems haven't affected every Mac, and 10.10.1 did the trick for some users. Apple hasn't said what exactly is causing the trouble with Yosemite Wi-Fi, or if another fix is coming to help users that are still dealing with connectivity problems. To install the update, select Software Update in the Mac App Store.
Apple has had to squash a host of bugs with its latest operating systems. iOS 8.0.1 killed cellular connectivity and Touch ID for iPhone 6 and 6 Plus owners in September, so Apple quickly pulled that update and released 8.0.2 days later. iOS 8 got an update Monday with improvements for iPad 2 and iPhone 4s users. No major problems have been reported with 8.1.1. To install the update, tap on Settings > General > Software Update.
