We’ve all ran into issues with our Macs, Yosemite has issues with upgrading and networking from feedback we’ve gotten from customers and have seen personally; and if you want to roll back to Mavericks, I suggest doing a clean install. Some might even find this handy before selling your existing Mac after getting a new one.

Ok folks, after many moons trying to fix this issue in Yosemite I finally got it… If you are running earlier versions of OSX, see here for the fix.
What am I talking about?
Append search domains for partially qualified domain names when performing DNS lookups. You know.. For example, you work in it and ssh to hosts regularly and your company uses
hostname.domain.com but you want to ssh to
hostname.sub to shave some time off your clock. With older versions you could apply a fix with mDNSResponder to work around whatever Apple decided to do there; around rolls Yosemite and they change the whole damn thing around.

Apple released their most recent update to their flagship OS that addresses issues many people were having to the point where some, including myself had to revert to Mavericks (sorry, did not do a write-up on that, was super busy with school and work). Basically, I was having drastic wireless connectivity issues that severely hindered my production, both at school and work. Continue reading OS X Yosemite v10.10.1 Update
We all have had that one time when your computer refuses to go to a site, or you can’t connect to something or a network. This is a result of a bad IP address or some other DNS result being cached in your system.
What is DNS caching
At it’s basic, DNS cache is simply how your computer remembers sites or networked locations and devices you’ve visited or networks you’ve connected to. It basically keeps the address that matches the URL of a site you visited for example.
How to flush
Flushing your DNS cache basically clears out all entries from your system and allows new entries to be made so that things flow smoothly. So here is how to do it on different systems.
Depending on the version of Windows you are using, the process to bring up a Command Prompt will be different but that is what you need. Basically you will want to do the following:
- For XP – Click Start -> In the Run box type cmd.exe and press Enter
- For 7 – Click Start -> All Programs -> Accessories -> right click on Command Prompt and click Run as Administrator
- Win8 and up – Simply type cmd which will bring up the search results to the right of your screen -> right click on Command Prompt and click on Run as Administrator
- Type ipconfig /flushdns and press Enter
- Open a command terminal and run the following:
- 10.8 Mountain Lion – sudo killall -HUP mDNSResponder then
- 10.9 Mavericks and up – dscacheutil -flushcache then sudo killall -HUP mDNSResponder
Open a terminal and run the following sudo dscacheutil -flushcache
A bug discovered in the widely used Bash command interpreter poses a critical security risk to Unix and Linux systems – and, thanks to their ubiquity, the internet at large.
It lands countless websites, servers, PCs, OS X Macs, various home routers, and more, in danger of hijacking by hackers.
The vulnerability is present in Bash up to and including version 4.3, and was discovered by Stephane Chazelas. It puts Apache web servers, in particular, at risk of compromise: CGI scripts that use or invoke Bash in any way – including any child processes spawned by the scripts – are vulnerable to remote-code injection. OpenSSH and some DHCP clients are also affected on machines that use Bash.
Ubuntu and other Debian-derived systems that use Dash exclusively are not at risk – Dash isn’t vulnerable, but busted versions of Bash may well be present on the systems anyway. It’s essential you check the shell interpreters you’re using, and any Bash packages you have installed, and patch if necessary.
Security expert Kenn White tweeted:
You can check if you’re vulnerable by running the following lines in your default shell, which on many systems will be Bash. If you see the words “busted”, then you’re at risk. If not, then either your Bash is fixed or your shell is using another interpreter. Continue reading Bash ‘Shell Shock’ bug blasts OS X, Linux systems wide open
