How To Find Mail Downloads On Mac

How to find and list all applications that exist in Mac computer storage?

In certain situations, you may need to know the number and type of applications installed on a Mac computer. This could be to check for malicious applications that are sometimes bundled with other software, or to list existing apps that might be occupying excessive storage space. If you have recently acquired a Mac, you may wish to know information about existing applications and this guide can help. Furthermore, if you are a keen or enthusiastic user, you can also manually check versions of installed software.

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, or 11.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. Mac desktop has been used for emailing for a while. User buys and adds additional Mac laptop. User wants to turn on Mail in Mac laptop and use it as well for emailing. User does NOT want all of the older (thousands) of email messages to download to new Mac laptop. User ONLY wants the email to work on the new Mac laptop from this day forward. Download Mail for Gmail for macOS 10.11 or later and enjoy it on your Mac. ‎Enjoy all the advantages of accessing your Gmail account, separate from your browser: - Quickly access Gmail from the menu bar - Badge dock icon with unread email counter - Receive and customize unread email notifications - Touch Bar support - Compact mode.

There are a number of ways to check all existing applications on the Mac as detailed here. The methods work with all versions of the Mac operating system. With the guidance offered, you can easily perform the checks. We start with simple methods, and then move to more advanced ones, which should present no problems if you carefully follow the steps within the guide. For example, we start with those requiring the least knowledge with Finder, and then walk through using Terminal and printing results into a text-based file on the desktop.

It is recommended to run a free scan with Combo Cleaner - a tool to detect malware and fix computer errors. You will need to purchase the full version to remove infections and eliminate computer errors. Free trial available. Combo Cleaner is owned and operated by Rcs Lt, the parent company of PCRisk.com read more.

Check installed apps via Finder

This is the easiest method, however, it also displays the least results: app names, date/time last modified, and size occupied on internal storage. Simply launch Finder and select the Applications folder from the left sidebar. Alternatively, press the keyboard shortcut of Shift, Command, and A. This will display all apps that were added through Mac App Store, came together with the operating system, installed through package managers, and manually attached by users via the drag-and-drop method. All user-level applications are included - enabling list view will allow you to freely scroll through existing apps.

Alternatively, Launchpad also serves to list applications and is one of the easiest way to locate apps for novice users. Note, however, that the Application folder is generally more useful for regular users. Furthermore, this method can be used to generate a list of all existing apps within a text-based file simply using a few keyboard shortcuts. In the applications folder, press the combination of Command and A to select all items within the window. Then press Command and C to copy the selection. Launch the TextEdit application using Spotlight - press the combination of Command and Spacebar, and then type TextEdit. In the text-based window, click on Edit in the menu bar at top of the screen, and then select Paste and Match Style.

You can save and rename this file. The applications folder can help you to determine which apps you might force to close, without crashing the operating system. You can also delete software directly from this folder. Detailed information can be found in this article.

Inspect the applications list through System Information

In you need more detailed information about each app stored on the computer, including system software, a more advanced method is available. This is simply a system report, and so you can use this option without fear of damaging the system, corrupting files, and so on. Therefore, you will not be able to delete or disable applications listed within the System Report. To access the information, hold down the Option (Alt) key on the keyboard and click the Apple logo in the menu bar at top of the screen. Then select System Information. In the new window, click on Applications under Software in the left sidebar. In the main area of window, you will see a list of all existing apps and additional information, such as version, source, where the app was obtained, and date/time of last modification. Clicking individual items in the list will display location in storage, information about the developer, and basic information expressed as a 'Get Info' string. User-level apps are displayed and also those necessary for system functions. Therefore, we strongly recommend that you do not delete or modify applications from this list, unless you are an advanced user (otherwise this could result in an operating system crash or making your computer inaccessible).

Find all application using Terminal

One of the most efficient methods to find app information is via the built-in command line application called Terminal. This, however, does require some advanced knowledge. Using this app, you can access useful functions, ignoring restrictions and even protected folders. To list all existing applications, you can use the find function, sudo command, which will grant access to all user and system folders. Launch Terminal using Spotlight - press the keyboard shortcut of Command and Spacebar, type Terminal, and then press Return. Alternatively, go to the Utilities folder under Applications. Once the application has launched, type the following command and press return to execute it (you will be asked to enter the administrators password, since you are trying to grant super user permissions):

• sudo find / -iname *.app

Since there are many files using the .app extension within the Mac operating system, displaying all them within a Terminal window might force the app and/or your computer to freeze. Therefore, as an alternative, we recommend that you print the results into a text-based file using the following command:

• sudo find / -iname *.app > ~/Desktop/ListAppFiles.txt

Using this syntax, all files that contain the .app extension will be written into the text-based file stored on the Desktop. You will also be able to find the location of those apps. This is probably the best option if you wish to check storage for possible malicious software - within the text file, you can use the Find function by clicking on Edit in the menu bar at top of the screen and selecting Find.

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) or Big Sur (11.xx.x) will need to uninstall all 3rd Party CAC enablers per https://militarycac.com/macuninstall.htm AND reenable the native smart card ability (very bottom of macuninstall link above)

If you purchased your Mac with OS Catalina (10.15.x) or Big Sur (11.xx.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, SCR-3310 v2.0, GSR-202, 202V, 203, or SCR-3500a reader. If you have a reader other than these 6, 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-3310 v2.0 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 “SCR3310 v2.0 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 6.02, it will not read the 'G+D FIPS 201 SCE 7.0' CAC on Mac OS 11.xx.x or 10.15.7. I contacted HID (the company that makes these readers) on 14 DEC 2020 to find a way to update the firmware to 6.02. They said there is not firmware update for the reader. If your reader is older, you may need a new one. Please look at: https://militarycac.com/usbreaders.htm to find a compatible one. If you are already at version 6.02, your reader should work fine on your Mac and no further hardware changes are required. You can now Quit System Profiler and continue to Step 3.

Step 2c1c-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 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, or 11.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 seven 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.
