I'm having trouble installing the drivers into my Late 2011 MBP OSx High Sierra 10.13.6
I've found several posts in this forum, but none of them seem to have my same problem, mine is just that the installtion program will stop in the middle of installation, and will stay there forever, not finishing the installation. Does anybody else had this problem and knows how to fix it?
thanks in advance.
Thank you for your inquiry about installing the CP210x VCP driver on your Late 2011 MBP OSx High Sierra 10.13.6. Can you please specify which version of the Mac OSX VCP driver you are trying to install? Also, is your OS a 32 or 64 bit OS? Thank you!
Hi! Many thanks for answering,
The version I'm trying to install is V 5.2.2 (latest), and my OS is 64 bit. Here are the full specs
MBP Late 2011 running Mac OS High Sierra 10.13.6
2,8 Ghz Intel core i7
16 gb 1333 DDR RAM
I've tried to install the legacy package, which seems to install fine, but doesn't work.
As I told before, V5 does not finish installing, it kind of stops (doesn't freezes the laptop or anything) in the screenshot I sent before, and I couldn't find anyone else having this problem.
Thanks for the details! There may be an issue with the Mac OSX VCP driver installation in which the OS blocks the driver installation:
"On MacOS 10.13 and later, the installation of the driver may be blocked. To unblock, open the System Preferences Security & Privacy pane and unblock the system extension. See Apple Technical Note TN2459 "User-Approved Kernel Extension Loading" for more information." (https://www.silabs.com/documents/public/release-notes/Mac_OSX_VCP_Driver_Release_Notes.txt)
Can you try making sure that the system extension is not blocked as described above and see if this resolves the issue? Thank you, and please let me know if you have any questions or continue having problems.
thanks again for answering.
That's not the problem, I'm aware of the system blocking some installers, but usually it blocks just as you open the installer.
It's just that it starts installing and as you see, the bar runs until "installing new driver", and stops right there, is kind of weird, never seen it before.
but I'm sure it's not the system blocking the extension...
I tried installing this driver on a Mac I have here in the office (although it is running OSX 10.14.6) and though I had to unblock kernel extensions, it still installed after that. Note that I was prompted by the installer to unblock the kernel extension during the "Install" step shown in your screenshot.
I am consulting with our driver team to see if we can provide any more guidance and troubleshooting on this issue. Thanks!
I am having the exact same problem after updating to OS Catalina V10.15. I have worked with both Davis and Apple. Apple now says I need to contact you. Can you give me any ideas as to where to go from here.
I get the same hang as described above. I have OK'd the install with via security and preferences.and the technical note described in your info I am trying to install version5.2.2 on a 64 bit OS.
Oddly enough Davis can do the install on their machine but it fails on mine.
Wow, I was starting to think this was something related to my old MBP running high sierra (eventhough so far I have had no problems with anything). I've been succsfull installing it on a mid 2013 MBP with high sierra.
So I don't know what's on my laptop that fails de installation. And seeing it also happens in Catalina makes it even weirder...
I am the person who wrote this installer. There are two issues. One is that you have encountered a bug in the installer and I would like to identify and fix it. The second problem is that you need to install your MacVCP Driver.
I want to focus on the second issue first (getting it working for you) so that you are unblocked. Hopefully you know your way around the Terminal and have a passing familiarity with Unix commands.
If you open the Terminal, you can type something like:
cd /Volumes/Silicon\ Labs\ VCP\ Driver\ Install Disk/
If you type "cd /Volumes/Silicon" and then press Tab the Termainal shell will autocomplete the path for you. Using this method, you can find the driver itself at the following path:
/Volumes/Silicon Labs VCP Driver Install Disk/Install VCP210x Driver.app/Contents/Resources/SiLabsUSBDriver.kext
Then you just need to copy the driver into /Library/Extensions/ like this:
sudo cp -r /Volumes/Silicon\ Labs\ VCP\ Driver\ Install\ Disk/Install\ VCP210x\ Driver.app/Contents/Resources/SiLabsUSBDriver.kext /Library/Extensions/
Using the sudo command in Terminal will cause a system warning message to be printed the first time you use it and will require you to type your password. And you have to be logged in with an account that has permission to use sudo, but if you are using an ordinary Administrator account on your Mac you will have permission to use it by default.
Then to load the driver you will type the following command:
sudo kextload /Library/Extensions/SiLabsUSBDriver.kext
This will result in an error asking you to open System Preferences 'Security' panel and approve the driver there. It will have a button that says something like "Allow" next to the Silicon Labs driver. Once you press Allow, if you are on a system that is older than Catalina it should just load the driver. On Catalina you will be prompted to reboot the computer and the driver won't install until you do.
Then the driver should be installed. If you plug in a CP210x part at this point, it should enumerate in the file system normally. The exact path depends on the VID/PID of the part you attach, but it will be at /dev/cu.<something>. One common name is /dev/cu.SLAB_USBtoUART
This brings us to the bug itself. If you are willing, I would like to follow up with you next week and see if I can figure out what is causing the issue you are seeing with the installer. Let me know if that would be okay.
I would also be happy to work with you if possible in order to get this resolved ...my email is firstname.lastname@example.org
Many thanks for answering and explaining on detail. Unfortunately this didn't work, I followed your steps, and when I tried to load the driver with this command:
sudo kextload /Library/Extensions/SiLabsUSBDriver.kext
As you said, I got that "error" message:
/Library/Extensions/SiLabsUSBDriver.kext failed to load - (libkern/kext) authentication failure (file ownership/permissions); check the system/kernel logs for errors or try kextutil(8).
I went to privacy and the "allow" button wasn't there
I'm starting to think this is because when I first tried to install this driver, it wasn't the latest version, its was the legacy one I think (my mistake of course), and when I installed the package I had to "allow" it, and since then the system allows any Silicon Labs software... I don't know if this might be a problem...
I don't know where to go from here...
I am at a dead end too and would appreciate any help you can provide.
So, I finally managed to make it work, but it was a little bit drastic, I formatted my MBP and did a clean install of high sierra, starting at 10.13.4, and the first thing I installed was the driver and it worked. Then upgraded to 10.13.6 and installed ALL my software again... IDK what was the problem, but sure was something on my OS...
Hi Luis. I am sorry you had to resort to such a drastic solution.
Steve - when you run the installer, I would like to know more about how the failure happens. There is a set of steps on the left side of the installer screen. When you get to the Info step, it should say something like "To Be Installed: Version 5.2.2" and "Currently Installed: None". Text below it might say "Version 5.2.2 will be installed in /Library/Extensions". Then it will say at the bottom "You will be prompted to enter your password."
When you click "Continue" on this step, I would like to confirm that you get a system dialog box that says "Install CP210x VCP Driver is trying to install a new helper tool." "Enter your password to allow this".
Also, I know this might be grasping at straws, but can you tell me the kind of account you are using to run the installer? The account types I see for High Sierra are: Administrator, Standard, Managed with Parental Controls, Sharing Only, and Group. There is also a Guest account on many systems. Also some accounts are "Managed" by an IT organization. My understanding is that in order to get past the System security dialog to run the installer, you would need to enter credentials for an Administrator account. Is that what you did? I'm just trying to figure out where the failure is happening in the installer.
Good Morning and thanks for replying. First off a bit of background. I am running Catalina not High Sierra. After updating to Catalina my weather link station quit. I worked withDavis first to fix the loading of weather link. After we got it working I noticed that the slab to Uart connection was lost. Oddly enough it was fine on the Davis copy of Mac OS Catalina. We tried everything we could but could not get it to reinstall. Again as I mentioned theirs installed fine. I then called Apple and spent about 5 hours on the phone with them.They had me send a number of dumps to them for analysis. They escalated the problem to their "senior" techs. After about 4 days they came back to me and said it was a problem with the install package and to contact you. Hence I am here. I am logged in as an admin.
I get the message 5.2.2 to be installed currently none installed. I am prompted for my password and enter it. It starts installing and then hangs at "installing new driver" with the progress bar about 80% filled in. I have attached a screen shot to this post. If need be you can contact me at email@example.com. I can also give you my apple case number if you have an in at Apple.
Just wondering if you had a chance to look into this at all
