If you’ve just recently switched from PC to Mac, you’ve probably noticed that instead of Internet Explorer or Edge that you’re used to, Mac has its own proprietary browser called Safari. In fact if you try searching for “download Internet Explorer for Mac” you’ll quickly realize that the exact IE equivalent on Mac doesn’t exist. What do you do then?

Interestingly, at the dawn of the world wide web in the late 90s, Internet Explorer was the default browser on all Macs. But when Apple introduced Safari as the new default browser in 2003, Microsoft has decided to discontinue the development of IE for Mac shortly after. So unless you run Mac OS X 10.6 or earlier (why would you?), there is no way to directly install Internet Explorer on Mac. And you definitely shouldn’t use the Internet Explorer versions from pre-2003 right now.

Windows apps alternatives for Mac?

Say no more. Here’s a curated collection of apps for any job available with Setapp.

How To Use Internet Explorer on Mac

Although natively launching Internet Explorer on Mac isn’t possible, there are other ways to simulate IE for Mac experience. You could mask Safari as different versions of Internet Explorer or Microsoft Edge, you could also install a virtual machine and launch IE for Mac that way, or you could simply choose to use any other third-party browser available on macOS.

Simulate Internet Explorer on Mac with Safari

Most of the time, if you need to use Internet Explorer on Mac, it’s probably for testing purposes, to see how certain websites or web apps perform, or to access websites that require you to use IE (yes, those still exist).

Both of those use cases could be easily performed by Safari. To use Internet Explorer with Safari, you just need to turn on developer tools:

1. In Safari, go to Preferences > Advanced
2. Check “Show Develop menu in menu bar”

Now you can access developer tools directly from Safari, which let you inspect websites, empty caches, and most importantly simulate a variety of other browsers right through the Safari app. To use Microsoft Edge or Internet Explorer on Mac:

1. Go to the Develop menu in Safari’s menu bar
2. Navigate to User Agent and select the browser you’re looking for, whether it’s Microsoft Edge, any of the Internet Explorer versions, Google Chrome, Firefox, etc.
3. The website you’re on will be automatically refreshed to reflect the browser of your choice. Just don’t forget to switch back!

The User Agent option in Safari should cover nearly all reasons for using Internet Explorer on Mac. However, if you do absolutely need to launch Internet Explorer itself for one reason or another, you could also try doing it with the help of a virtual machine.

Launch Internet Explorer on a virtual machine

While using a virtual machine for Internet Explorer is not by any means an easy solution, it’s still there for anyone who needs it. What virtual machine essentially does is installing a full-scale copy of Windows on your Mac and letting you launch it as an app inside the macOS. From there you can launch Internet Explorer or, in fact, any program you miss from your Windows days.

To set up virtual machine, first you need to buy a copy of some virtual machine software (VMware Fusion is a good one) and a license for Windows. Once you have those in place:

1. Download both VMware fusion and the Windows ISO file
2. Launch VMware Fusion
3. In the Installation Method window, choose “Create a new custom virtual machine”
4. Drag and drop your Windows ISO file onto the dialogue window
5. Click Finish
6. Relaunch the virtual machine and click the play button to setup Windows

Now every time you need to use Internet Explorer on Mac, you can just launch the virtual machine and use IE directly with Windows that way. There are certainly a few downsides to this solution. First, you have to purchase both VMware Fusion and a licensed copy of Windows for the sole purpose of using Internet Explorer. Second, virtual machines tend to be quite heavy on your processor, as they are running the whole operating system inside them.

Another option available to you in case you don’t specifically need to use IE for Mac but rather move away from Safari is to switch to any other third-party browser, all of which are freely available on macOS.

Use third-party browsers on Mac

If Safari is not your first browser of choice and using Internet Explorer for Mac is at the very least quite complicated, you can download any other stable and widely used browser out there and make it the default one on your macOS.

Google Chrome

By far the most dominant browser of today, Google Chrome currently commands 45–65% browser market share. Developed by Google, the browser is available on both desktop and mobile devices, and thus boasts a significant amount of plugins and web apps that are exclusive to it. Chrome has also been praised for its speed and tight integration with all other Google products. As for the downsides, using Chrome means being subjected to Google’s pervading tracking and helping Google to effectively monopolize the web.

Firefox

Firefox is another great everyday browser. Heir to the first commercial web browser called Netscape, it’s an open-source program owned by the not-for-profit Mozilla Foundation. Firefox is fast, secure, and boasts a supportive community around the world. All of this makes it a great alternative to Safari and Internet Explorer.

Brave

Brave is a newcomer to the browser arena that first appear only in 2015. Based on the open-source Chromium project (as is Google Chrome), the browser quickly gained a loyal following due to its aggressive privacy controls and ad blocking. Turning Brave into your default browser might seem a bit experimental at this point, but it nevertheless presents a good option for anyone concerned with privacy.

Microsoft Edge

Although not available on macOS as of early 2019, Microsoft has announced that it’s currently rewriting the Edge browser engine to run on Chromium (like Google Chrome and Brave), which means it will become compatible with macOS too upon release. Fingers crossed, but in the meantime you can choose one of the alternative browsers listed above.

Overall, these are your three options of running Internet Explorer on Mac. You can use Safari’s User Agent to view any webpage just as Internet Explorer would, launch the actual Internet Explorer browser through a virtual machine running Windows, or choose one of the alternative browsers if all you want to do is get away from Safari on Mac.

However, if you’re new to Mac, a browser might not be the only thing you’re concerned about. You also need to find apps to cover all kinds of issues related to optimization, organization, security, and productivity.

Essential apps for all new Mac owners

As soon as you switch from PC to Mac, you realize that sadly not all apps you loved and used daily are available on macOS. So naturally you need to find suitable replacements.

Bartender

Why Wont Internet Explorer Download On My Macbook Air Pro

A lightweight utility performing a vital role, Bartender keeps your menu bar clean and tidy. As you use your Mac more and more, every new app would want to be featured in your menu bar (top-right corner). This quickly becomes unsustainable, and instead of a quick access to the apps you need, you’ll spend more time just trying to find the right one.

Mac’s default organization settings for menu bar are quite basic, only allowing you to reshuffle icons. Bartender lets you hide them under a single icon and feature just those you need to use right at the moment.

Ulysses

Lauded as the best writing tool for years, Ulysses features a clean interface and lets you focus on the writing process, whether it’s for simple notes, speeches, or anything in between. And the app’s Markdown support makes it much more web friendly, allowing direct exports to WordPress and Medium.

Disk Drill

No one ever wants to lose their files, no matter whether it’s due to physical damage or accidental deletion. Disk Drill solves that problem by essentially insuring and giving you the option to recover your files. As the most widely used data recovery tool around, Disk Drill helps you back your files on a regular basis and save lost files from damaged hard drives if things ever go south.

CleanMyMac X

The ultimate Mac optimization app, CleanMyMac X keeps your Mac free of any junk, safely and completely uninstalls old apps, and protects you from being affected by malware. Just launch CleanMyMac X once a month to do a complete scan of your computer and you’ll ensure your Mac’s top condition.

Best of all, Bartender, Ulysses, Disk Drill, CleanMyMac X, and all other apps featured on Setapp are available to you on a free trial. Just launch Setapp and try out as many apps as you want, turning your transition to Mac from a chore to a pleasurable discovery.

Meantime, prepare for all the awesome things you can do with Setapp.

NOTE:

Between mid October 2019 and mid February 2020 everyone in the Army was migrated to use their PIV Authentication certificate for Email access. You no longer use the Email certificate for Enterprise Email or any CAC enabled websites

Mac users who choose to upgrade (or already have upgraded) to Mac OS Catalina (10.15.x) will need to uninstall all 3rd Party CAC enablers per https://militarycac.com/macuninstall.htm AND reenable the built in smart card ability (very bottom of macuninstall link above)

If you purchased your Mac with OS Catalina (10.15.x) already installed, you can skip the uninstall part above and follow the instructions below.

6 'high level' steps needed, follow down the page to make this a painless systematic process

Step 1: Is your CAC reader Mac friendly?

Visit the USB Readers page to verify the CAC reader you have is Mac friendly.

Visit the USB-C Readers page to verify the CAC reader you have is Mac friendly.

'Some, not all' CAC readers may need to have a driver installed to make it work.

NOTE: Readers such as: SCR-331 & SCR-3500A may need a firmware update (NO OTHER Readers need firmware updates).

Information about these specific readers are in Step 2

Step 2: Can your Mac 'see' the reader?

Plug the CAC reader into an open USB port before proceeding, give it a few moments to install

Step 2a: Click the Apple Icon in the upper left corner of the desktop, select 'About This Mac'

Step 2b: Click 'System Report...' (button)

Step 2c: Verify the CAC reader shows in Hardware, USB, under USB Device Tree. Different readers will show differently, most readers have no problem in this step. See Step 2c1 for specific reader issues.

Step 2c1: Verify firmware version on your SCR-331 or GSR-202, 202V, 203 CAC, or SCR-3500a reader. If you have a reader other than these 5, Proceed directly to step 3

Step 2c1a-SCR-331 reader

If your reader does not look like this, go to the next step.

In the 'Hardware' drop down, click 'USB.' On the right side of the screen under 'USB Device Tree' the window will display all hardware plugged into the USB ports on your Mac. Look for “SCRx31 USB Smart Card Reader.” If the Smart Card reader is present, look at 'Version' in the lower right corner of this box: If you have a number below 5.25, you need to update your firmware to 5.25. If you are already at 5.25, your reader is installed on your system, and no further hardware changes are required. You can now Quit System Profiler and continue to Step 3.

Step 2c1b-SCR-3500A reader

If you have the SCR3500A P/N:905430-1 CAC reader,you may need to install this driver, as the one that installs automatically will not work on most Macs. Hold the control key [on your keyboard] when clicking the .pkg file [with your mouse], select [the word] Open

Step 3: Verify which version of MacOS do you have?

(You need to know this information for step 6)

Step 3a: Click the Apple Icon in the upper left corner of your desktop and select 'About This Mac'

Step 3b: Look below Mac OS X for: Example: Version 10.X.X.

Step 4: Figure out which CAC (ID Card) you have

(You need to know this information for step 6)

Look at the top back of your ID card for these card types. If you have any version other than the six shown below, you need to visit an ID card office and have it replaced. All CACs [other than these six] were supposed to be replaced prior to 1 October 2012.

2. Download the allcerts.zip file and install each of the certificates you are missing individually.

Errors:

Error 100001 Solution

Error 100013 Solution

You may notice some of the certificates will have a red circle with a white X . This means your computer does not trust those certificates

You need to manually trust the DoD Root CA 2, 3, 4, & 5 certificates

Double click each of the DoD Root CA certificates, select the triangle next to Trust, in the When using this certificate: select Always Trust, repeat until all 4 do not have the red circle with a white X.

You may be prompted to enter computer password when you close the window

Once you select Always Trust, your icon will have a light blue circle with a white + on it.

The 'bad certs' that have caused problems for Windows users may show up in the keychain access section on some Macs. These need to be deleted / moved to trash.

The DoD Root CA 2 & 3 you are removing has a light blue frame, leave the yellow frame version. The icons may or may not have a red circle with the white x
