When you configure a proxy server on your Mac, applications will send their network traffic through the proxy server before going to their destination. This may be required by your employer to bypass a firewall, or you may want to use a proxy to bypass and access websites that aren’t available in your country. RELATED: The proxy server you set here will be used by Apple Safari, Google Chrome, and other applications that respect your system proxy settings. Some applications, including Mozilla Firefox, can independent from your system settings. Open the System Preferences application by clicking on it in your Dock, or going to the Apple menu > System Preferences. Click the “Network” icon.
Select the network connection you use in the list. For example, if you want to configure the proxies used while connected to Wi-Fi networks, select “Wi-Fi”. If you want to configure the proxies used while connected to wired networks, click “Ethernet”. Click the “Advanced” button at the bottom right corner of the Network window. Select the “Proxies” tab. You’ll need to configure a proxy by enabling one or more of the protocol checkboxes here. To have your Mac detect whether a proxy is necessary and automatically configure the proxy settings, enable the “Auto Proxy Discover” checkbox.
Your Mac will use the Web Proxy Auto Discover protocol, or WPAD, to automatically detect whether a proxy is necessary. This setting may be used on business or school networks, for example. Even after enabling this option, your Mac will only use a proxy if one is detected using WPAD.
An update to my issue: It seems to be limited to Outlook (2011, Mac). I have been using Outlook for years with both my corporate Exchange account and my Comcast account using POP mail.
So, you just bought an external hard drive and wanted to use it on your Mac. But somehow, macOS doesn't allow you to write data to the drive. That's all because it's been initialized with Windows NT File System (NTFS), which is primarily for PCs. Apple Mac machines support a different file system. Mac external hard drive time machine.
If you never want your Mac to use a proxy, even if one is detected with WPAD, leave this box unchecked. To use an automatic proxy configuration script, also known as a.PAC file, enable the “Automatic Proxy Configuration” checkbox. Enter the address of the script in the URL box.
Your network administrator or proxy provider will provide you with the address to the proxy configuration script, if you need one. If you don’t need to use an automatic proxy configuration script to configure your proxy settings, leave this box unchecked.
To manually configure a proxy, you’ll need to enable one or more of the “Web Proxy (HTTP)”, “Secure Web Proxy (HTTPS)”, “FTP Proxy”, “SOCKS Proxy”, “Streaming Proxy (RTSP)”, and “Gopher Proxy” checkboxes. Enter the address and port number of the proxy for each option you enable. If you were provided with a username and password for the proxy server, enable the “Proxy server requires password” option and enter the username and password. For example, let’s say you want to configure a proxy that’s used for HTTP, HTTPS, and FTP connections. You’d check the “Web Proxy (HTTP)”, “Secure Web Proxy (HTTPS)”, and “FTP Proxy” boxes. After checking each, you’d enter the address and port of the proxy server into the right pane.
If you want to use the same proxy server for all three, you’d enter the same address three times. If you were provided with different proxy server addresses for different protocols, you’d enter different proxy server addresses for these connections. If you don’t want to manually configure a proxy, ensure all these boxes are unchecked. The remaining settings allow you to bypass the proxy server when connecting to specific addresses and domains you configure.
The “Exclude simple hostnames” checkbox allows you to bypass the proxy for all “simple hostnames”. These are often used on local networks and intranets. For example, a network might have a local website at “portal” or a local file server at “fileserver”.
