How to Get Root Certification Authorities List from Android Phone Connected by USB in Mac OS X

1. Make sure you have adb installed, and if not install it via homebrew.

$ which adb
$ brew install adb
Note: You can also determine the Android SDK version of the device by typing:
$ adb shell grep system/build.prop
2. Log into the android phone terminal by typing this command in the mac terminal.
$ adb -d shell
shell@android:/ $

3. Navigate to the /system/etc/security/cacerts directory or whatever directory that contains the certificate authority certificates and then you can list the root certification authorities on that phone. 
$ cd system/etc/security/cacerts/ 
$ ls 
shell@android:/system/etc/security/cacerts $ ls
4. Once you've located all of the certificate authorities certificates you can pull then to your local computer by typing this command:
Note: I created a folder called android-certs on my local computer and the "." command says to copy all of the files to the current directory. 
Kurrys-MacBook-Pro:android-certs ktran$ adb pull /system/etc/security/cacerts/ .
pull: building file list...
pull: /system/etc/security/cacerts/ff783690.0 -> ./ff783690.0
pull: /system/etc/security/cacerts/fde84897.0 -> ./fde84897.0
pull: /system/etc/security/cacerts/fb126c6d.0 -> ./fb126c6d.0

5. Once you have all of the certificates in the folder you can use the command line tool grep to find all issuers. Run this command:

$ grep "Issuer" *
You should see something like this:
00673b5b.0:        Issuer: C=US, O=thawte, Inc., OU=Certification Services Division, OU=(c) 2006 thawte, Inc. - For authorized use only, CN=thawte Primary Root CA

08aef7bb.0:        Issuer: C=US, O=Wells Fargo WellsSecure, OU=Wells Fargo Bank NA, CN=WellsSecure Public Root Certificate Authority
0d188d89.0:        Issuer: C=TR, O=Elektronik Bilgi Guvenligi A.S., CN=e-Guven Kok Elektronik Sertifika Hizmet Saglayicisi
