May 25, 2015 Basic: Visit the /Applications/ Folder in OS X to See Installed Mac Apps. The simplest approach to see what apps are on a Mac is to visit the /Applications folder, this will show all apps that users have installed through the App Store, that came bundled with the Mac, and that have been installed through most package managers, and by user drag & drop.
It has a 2.4G USB receiver. My wifi is coming from a repeater. Over the last week I have been having problems with getting pages to load. I have almost full strength bars on my Sony Vaio laptop (windows 7) and it just doesn't work. I have reset the repeater about one hundred times. Today I decided to get to the bottom of this issue. Mar 15, 2016 I just installed Windows 10 on a new Boot Camp partition. Everything has installed, but I'm having issues with WiFi. It can connect to my phone's Hot Spot, which is how I'm typing this, but it can't connect to the home WiFi network, which the same machine has no problems with when running in OSX.
Installed Software Messing Up Wifi Mac To Tv
When you’re connected to the internet on your Mac, there’s a WIFI icon at the top that stays white. However, when your Mac detects a WIFI failure. The white WIFI button turns gray and has an X in it.
If you hover over the icon, you’ll see an error message saying, “WIFI: No Hardware Installed.”
If you require internet daily, and you don’t know how to fix this problem, it can be daunting since you’re not aware of what’s causing this problem. It usually occurs when: you’ve turned on your Mac: restarting your Mac, or after a software update.
The Reason the Error Occurs
The reason you’re seeing the error, “WI-FI: No Hardware Installed” is because your Wifi adapter isn’t installed properly. The WIFI adapter installed on your Mac can fail without any particular reason and this can cause your WIFI to stop working. You need to install of restart your WI-FI adapter to remove the error.
1. Reset SMC your Mac
The system management controller is an integrated circuit that is on the logic board of the MacBook or MacBook Pro.
This integrated chip is responsible for the power management of your Mac. You can reset the SMC and it should remove the error message.
To reset the SMC:
- Shut down your mac and connect it to the charger.
- Hold the Shift + Control + Option + Power button keys together for 5 seconds.
- Release the key.
- Wait for your Mac to boot up. Check if the error message has gone and if you’re able to connect to the internet.
2. NVRAM Reset
Nonvolatile random-access memory is a small memory that your Mac uses to store certain settings and access them quickly. Since the WIFI problem is related to your settings, resetting the NVRAM might help.
- Shut down your Mac. Locate Hold Command (⌘), Option, P, and R and be ready to hold them.
- Turn on your Mac.
- Press and hold the Command-Option-P-R keys once you hear the startup sound.
- Hold these keys your Mac restarts and you hear the startup sound again. Check if your WIFI is working and if the error message has gone.
3. Reset PRAM
PRAM is a type of memory in your Mac that stores system settings. Since your WIFI adapter may be failing, resetting the PRAM might help to fix this.
To reset the PRAM:
- Reboot your Mac.
- As soon as you hear the chime, hold down Command + Option + P + R. The next time you hear the boot chime, the PRAM should be reset.
- Wait for the Mac to boot up.
- Update your Mac.
Once your PRAM has been reset, you can check if the error message has gone. If this didn’t help the WIFI problem, you’ll need to install any software updates on your Mac.
4. Install Software Updates
If you have current software updates that haven’t been installed, installing them might fix the issue. If your software is out of date, then there may be a bug on your Mac that stops your WIFI from working.
You’ll first need to install any outstanding software updates on your Mac. Once these are installed, you’ll need to safe reboot your mac. To start up in safe mode: Restart your Mac, then immediately press and hold the Shift key.
The Apple logo appears on your display > Release the Shift key when you see the login window. Once you’ve done this, restart your Mac again and check if the error message has gone.
5. Rename .conf File
On your Mac, there’s a configuration file name /etc/sysctl.conf that’s responsible for the IPv4 forwarding parameter. This file was present in old Macs but in modern Mac, they’re not present and they can cause your WIFI adapter to fail.
To check if /etc/sysctl.conf is present on your Mac:
- Go to Applications > Utilities > Terminal.
- Enter the following command:

“ls -l /etc/sysctl.conf.” The terminal should tell you that there’s “No such file or directory.” This means that the file doesn’t exist. If you see “-rw-r–r– 1 root wheel 136 24 Nov 2013 /etc/sysctl.conf“ instead, it means that your Mac has the old sysctl.conf file.
- Rename this file to make it invalid. Check if the error message has gone and if you’re connected to the internet.
