Then look for Terminal. Terminal can be used to get a local terminal window, and also supports SSH connections to remote servers.

By editing Mac hosts file, it’s possible to emulate DNS change and set the desired IP for a domain name. With the hosts file you can overwrite any DNS values set by your Internet service provider. This is helpful if your domain name is not yet registered or not pointed to a hosting account, but you want to preview your website.
In this tutorial you will learn how to edit the hosts file on Mac. For a tutorial on how to do the same on Windows click here.
IMPORTANT: Note that changes made for the hosts file will affect your computer only.
What you’ll need
Before you begin this guide, you’ll need the following:
- root user privileges
Step 1 – Opening Hosts File
Follow these steps to open your hosts file on Mac:
- Access launcher (F4 key) and type in
terminalin the search field. Click on the Terminal icon. - We will use Nano text editor to open the hosts file. You can open it with Nano by executing the following command:
sudo nano /private/etc/hosts - As we use sudo to edit the hosts file, you will be asked to enter the password of your Mac user account. Note that due to security reasons the cursor won’t move. This is normal – simply enter your password and hit the ENTER key.
Step 2 – Editing Hosts File on Mac
In order to emulate DNS change and point domain name to an IP address, use the following syntax:
For example, to emulate DNS change for hostinger.com and www.hostinger.com we would have to include the following lines at the bottom of hosts file.
This will emulate change IP address of the hostinger.com and www.hostinger.com to 93.188.160.58.
Once you are done with editing hosts file, press CMD + X on your keyboard, enter Y to save changes and hit ENTER button.
Step 3 – Flushing DNS Cache (Optional)
Sometimes changes do not apply instantly and you may need to flush the DNS cache. On Mac, DNS cache can be easily flushed by executing the following command:
Mac OS X Snow Leopard
OS X Mavericks, Mountain Lion, and Lion
Conclusion
That’s it, by finishing this short tutorial, you have learned how to edit a hosts file on Mac. This is useful if your domain name is not registered or not pointed to the server, but you want to preview your website. In addition, you have also learned how to flush the DNS cache on Mac.
- 1QEMU on OS X (macOS) hosts
While QEMU's main host platform is Linux, it is also supported on operating systems for Apple's Mac computers (known as OS X or macOS). The official support policy covers the last two released versions of OSX; QEMU might work on older versions, but it is not guaranteed and it might not even compile on older versions.
Please note that fewer developers work on QEMU for Mac hosts, so it might be less stable (but I don't think it is). If you can replicate a bug on a Linux hosted QEMU before reporting it, this is helpful as it means a wider set of people might look into it.
Some system emulations on Linux use KVM, a special emulation mode which claims to reach nearly native speed.KVM is mainly used for x86 (32 and 64 bit) emulation on x86 hosts running Linux. Should you want to run Qemu with KVM support on a G5, depending on your distribution, you might have to compile your own kernel with KVM support.There exists a port of QEMU to Hypervisor.framework (a kernel module from Apple which is similar in spirit to KVM), but unfortunately it is not included in upstream QEMU.
Building QEMU for OS X
The system requirements are:
- One of the last two most recent versions of OS X (currently that's 10.13 or 10.14)
- The clang compiler shipped with the version of Xcode for that OS X. GCC might also work, but we recommend clang
Additional build requirements are:
You may find it easiest to get these from a third-party packagersuch as Homebrew, Macports, or Fink.
After downloading the QEMU source code, double-click it to expand it.
Then configure and make QEMU. The target-list option is used to build only the machine or machines you want. If you don't specify it, all machines would be built. Probably not what you want.
This way doesn't require you to wait for the configure command to complete:
If your system has the 'say' command, you can use it to tell you when QEMU is done
You can use './configure --help' to see a full list of options.
Here are all the currently available machines:
- aarch64-softmmu
- alpha-softmmu
- arm-softmmu
- cris-softmmu
- i386-softmmu
- lm32-softmmu
- m68k-softmmu
- microblaze-softmmu
- microblazeel-softmmu
- mips-softmmu
- mips64-softmmu
- mips64el-softmmu
- mipsel-softmmu
- moxie-softmmu
- or32-softmmu
- ppc-softmmu
- ppc64-softmmu
- ppcemb-softmmu
- s390x-softmmu
- sh4-softmmu
- sh4eb-softmmu
- sparc-softmmu
- sparc64-softmmu
- tricore-softmmu
- unicore32-softmmu
- x86_64-softmmu
- xtensa-softmmu
- xtensaeb-softmmu
We recommend building QEMU with the -default compiler provided by Apple, for your version of Mac OS X (which will be 'clang'). The configure script will automatically pick this.
Errors on old compilers
Note: If after the configure step you see a message like this:
Hosts For Mac Os X 10.8
you may have to install your own version of gcc. You can build it from source (expect that to take several hours) or obtain third party binaries of gcc available from Homebrew or MacPorts.
You can have several versions of GCC on your system. To specify a certain version, use the --cc and --cxx options.
Build with LLVM/Clang 7
If you need to compile with newer versions of clang (to get f.i. AVX/AVX2 support), you can install llvm through e.g., brew.
Note that building for machines with CPUs supporting such extensions will exclude running your binary on earlier machines.
