It seems like Apple Inc.'s attempt to fix the Wi-FI bug plaguing the new operating system was not as successful as hoped, and that the OS X Yosemite update did not actually deliver.

According to reports, the OS X 10.10.1 patch that was released this week failed to fix the Wi-Fi issues that have been bothering Mac users who downloaded the Yosemite update in October.

Apple even promised that other issues will be fixed by the OS Yosemite patch that came out on Monday, including the connection to Microsoft Exchange server, the issue that blocks Mail from carrying out messages using other email service providers, and the issue that stops the remote computer connection using the Back to My Mac.  There is also the issue experienced by Mac users when sharing services, and the issue of the Notification Center widgets becoming unavailable.

The list of other issues that the OS X 10.10 Yosemite patch is supposed to address includes:

• Addresses an issue that could cause Notification Center settings to not be retained after a restart
• Addresses an issue that might prevent the Mac App Store from displaying certain updates
• Addresses an issue that could prevent some Mac mini computers from waking from sleep
• Resolves an issue that might prevent Time Machine from displaying older backups
• Addresses an issue that might prevent entering text in Japanese

Those who have already downloaded the patch aired their complaints on the Apple support forum. One of the dissatisfied Mac user said, as quoted by ZDNet, "Stil [sic] the same S**T. One month later, I'm starting to think Apple laught [sic] at us. Or they are completely lost."

However, there are a few who expressed their contentment with the patch fix, saying, "10.10.1 fixed the wifi issue. I had minor random wifi drops with Yosemite prior to the update. now it's smooth sailing. Very quick and responsive."

The OS X Yosemite patch update can be downloaded on the Mac Apple Store.
