Samsung Portable SSD T5 not recgonized on Macbook

Ok so the solution to this as of right now is to completely uninstall the portableSSD software then install the older version of the software version 1.6.2. Only version 1.6.2 will work right now.

The issue is that in the newest version of OS in Mojave, apple as created stricter protocols for 3rd party software. All software will need to have all of there kernel files approved by apple prior. (something like that anyways, I'm not a programmer.)

There is plenty of internet gossip about this new security change by apple, they gave notice to companies but not all companies have implemented it yet. So I'm sure at a later date there will be a SSD software that is updated that works with Mojave, but for now you need to get an install copy of PortableSSD v 1.6.2. The only way you can get it is by emailing Samsung support here: samsungmemory@hanaro.eu

They got back to me pretty quick, I sent the email in the evening and got a copy from them the next morning. As soon as I installed it, it worked immediately.

You can fully uninstall the ssd software by doing the following these steps:

• Open finder, in the go dropdown on the top left select "Go to folder..."
• paste in the following, ~Library/application support/portableSSD (if this doesn't find the file directory, try ~Library/application support/samsungportablessd)
• in the folder you will see a few different files, double click to open the CleanAll.scpt (make sure you have admin privileges)
• Click the 'play' symbol on the top left of the window. This will erase all SSD software buried within the library systems and uninstall the software. (note: I had errors here, mainly files that aren't found. From my understanding, these are the missing kernel files that are causing it not to work. don't worry though, even with errors the soft ware will uninstall.)
• Now the software is uninstalled, delete any left over shortcuts and empty your trash.

Good luck and I know how you feel!

Disregard.

I was using a USB hub, but once I connect my ssd directly to the laptop, it worked perfectly.

What version of the Samsung software version are you running. The latest version won’t run on mojave. You have to run the previous version. Samsung will send you a link to download it. Contact their tech support. I ran into the same issue

I found a fix for this frustrating problem. You may go to the samsung.com website and locate the following download. It apparently comes from an Australian website. After downloading this software all I had to do was click on the Samsung SSD application and the password window came right up. Entered my already established password and the device worked just fine.

DO NOT INSTALL THE UPDATES - (2) listed at this writing - or the problem will reoccur.

try pasting this, ~Library/application support/ , in there to get to the application folder then just scroll to through the folders and look for anything called "portablessd" maybe Samsung. if you cant find the folder i dont believe you ever had it installed.

As far as Samsung, Maybe just email them back and request a installation copy of portableSSD v 1.6.2

I explained to them that I have completely uninstalled and reinstalled the software and have tried both the updated and non updated version of the software that came on my drive.

OR

you can download the software from the Australian site as well, Version 1.6.2 that is. I found this at the same time I got an email back.

Good luck!

So the new Samsung ssd software is version 1.6.4. To get the drive to work you need the previous version, 1.6.2. I searched google and found it but other posts suggest emailing Samsung and getting a copy.

Hope that helps!

Evening Inorton44: Please see the immediately preceding post regarding a fix for this annoying issue with the Samsung T5 SSD.

Steps:

1. First uninstall the current Samsung software on your Mac as outlined in bgray1125's postings above.
2. bgray1125's post also has a link to the Samsung Australian download link for Activation Software 1.6 which is the software that will fix your problem. The software link for the Activation Software is also found in the Samsung India website. If you copy and paste the reference in my post into Google one of the listings will be the India site that will take you to the needed software download.
3. DO NOT UPDATE V 1.6. Be sure not to update the software or it will undo the fix and take you right back to the initial problem of not recognizing the SSD.

Hope this helps you re-access your photos.

if You are not able to find file CleanupAll.scpt. and it fails to install old version further, complains that upgraded version is already installed. Try this.

1)Delete the folder PortableSSD and reinstall the latest updated version. Empty recycle bin/Trash

2) Goto ( you cannot see this folder graphically) : <U is capital>

cd /Users/<your logged in username>/Library/Application\<space>Support/PortableSSD/

ls <enter>

3)your logged in username should be the same name as you see while login and preferably match the account using which the last time app was installed.

MacBook Pro OS 10.14.6 - If FireValut is "ON" means "encrypted mode, Samsung SSD T5/T3 not able access from MacBook Pro. Once I turn off the FireValut means "decrypted" mode. Reinstall Samsung SSD driver and able to access Samsung SSD T5 without any issue.

Still did not work, as there are ghost files that WILL NOT leave my MacBook.

heres how I fixed it @edmundo139 :

I had to install the Australian download (see earlier commentary within this thread) on a DIFFERENT Mac and run the drive through that.

Be sure to NOT update the v1.6 Australian download.

you should be good after that.

I simply used the Disk Utility app that comes with Mojave (Applications/utility folder) to erase and reformat my Samsung SSD to Mac format. That means it won't be accessible to Windows PCs but it suits me.

BTW - I have found my Macbook sometimes needs an SMC reset in order to use external drives - see https://support.apple.com/en-us/HT201295

It’s not the format of the SSD that is the issue. I formatted it exfat. The issue is the Samsung software. All of the removal procedures say to remove the software from the application folder but in my case the Samsung SSD folder within the application folder doesn’t exist. Because within the Samsung SSD folder is where the script is to do the uninstall. Samsung suppprt was no help

Hi There

Please know that Samsung T5 SSD Driver Software is not compatible with Catalina.

Use the method as described by _bburr below and it seems to work.

But had to use it every time to open the SSD.
