CAC Reader no longer works after Upgrade to Monterey

I have the new MacBook Pro M1 Max (2021) laptop. I've never installed anything. This computer came with Monterey 12.0.1. I tried the steps mentioned about about opening Terminal window and paste the long command, typing my password (twice), restarted, etc. I was never prompted to select a certificate, enter a PIN - nothing. It appears to STILL NOT be reading the car- reader (SCR3310 v2.0). Could really more assistance. Thanks in advance.

What OS did you upgrade from?

Pre-Big Sur usually required CAC enabling software to work. Those same CAC enablers will prevent it from working in Big Sur and later. So, if you upgraded from an OS previous to Big Sur, you may still have the CAC Enabler software installed and it needs to be removed. MilitaryCAC.com has instructions somewhere on the site.

I even reinstalled the drivers for my SCR3310,v2 CAC reader.

That reader doesn't need any drivers. Maybe those are the cause of your problems.

I've used that same reader on both Intel and M1 Monterey Macs without issue. I have never installed a driver for it on any macOS version.

No idea the address I use is webmail.apps.mil. Works much Better on Monterey than it ever did on any other OS.

try opening a new private window and see if you can connect from there. That should prevent any cache data from being sent

Thank you for sharing. I recently upgraded to Monterey and now trying to set up my SCR3310 v2 CAC reader (was never set up before). However, after following all the instructions on militarycac.com, my CAC reader still will not read the card it seems.

I get the following message:

"An unexpected error occured validating your certificate. In order to log in with your Smart Card, please close your browser and all tabs associated with it and try again using the Authentication certificate or log in with your LOGIN ID and Password."

Do I need additional software in order for CAC reader to read my card and display certificate options? What is "VMware Horizon" and do you have a link for it, assuming that is what I am missing?

No. If you have ever installed anything to use that reader or your CAC, you must remove it.

If you haven’t installed anything, it should work. You won’t see anything in keychain access. You will only get a pop up dialog asking which certificate you want to use, then a PIN entry.

I upgraded my MAC to Monterey and I need to install my military CAC for the first time. I haven't been able to locate good instructions to do so. I have used militarycac.com, homecacuse.com etc and nothing. Any IT guru with guidance and links I could follow? Thanks!

There should be nothing to install.

Plug in the reader, plug in your CAC, use it when requested.

Don’t pair when requested. It does nothing to help you access CAC-protected services.

If you pair, you will need to use your CAC pin to authenticate Mac services, like logging into your Mac.

If connected through a hub, try direct-connect to a USB port (with adapter if needed). You should see the light blink at least once when you connect it. If it doesn’t, it isn’t talking to your Mac.

As I said before, you should not need to do any installing or configuration. Hoping that running some random command you find on the Internet can only make things worse.

I have a related question, welcome any insight.

BLUF I have solved this problem by using Chrome (24" iMac M1 Monterey 12.0.1 Safari 15.1)

However-

Tried Safari to access DOD healthcare site using CAC login, Safari sees the certificates, asks me for PIN and then says "cannot establish a secure connection to the server".

Used Chrome on a whim and worked FIRST TIME no problems whatsoever.

What is up with Safari and DOD CAC Login?

I used to use Thursby PK software years ago but removed it all since CAC support is now integral to Mac OS, I double checked and it's definitely not there.

Safari caches certificates (at least that's my interpretation). I always use a private browser to prevent it caching anything.

Microsoft Edge works pretty well, too. And, you can turn a webpage into an "app." So, you can turn webmail into an App that you just double-click to open. Chrome may do the same as Edge is chromium based.
