Did fine with NI-488.2 and NI-VISA_Runtime and LabVIEW2019SP1RuntimeEngine but when I got to SiLabsUSBDriverDisk, even though I did the "allow" thing in the security preferences, I still got this message:
"Driver may need approval. CP210x VCP driver is not loaded, but is present in the file system. This could indicate that the driver needs user approval in the system preferences." But not sure what to do beyond what I already did in that regard. Note that Silicon Labs shows up in the list of blocked entities, but the box next to it is NOT checked, so I am assuming that means that it is in fact NOT blocked, as the other installed parts also show up on that list but also indicated installed successfully.

And finally - when i went to do the control open thing with isaac, the loading splash screen showed up, but then immediately disappeared and nothing else happened. And for what it is worth, the old 4.1 of Isaac is still in my applications folder but showing up as not working with catalina.

Suggestions? Thanks.

After installing Catalina (10.15.2 for example) you might find a folder "Previously Relocated Items" which contains a number of aliases to National Instrument shell scripts of other similar files. These are not easily deleted - You will get error messages that MacOS requires them - although they are only aliases (icons have an arrow in them, or if you "get Informalities" they point to file located in system file, share directories of similar locations.

They really are harmless. But if you want to get rid of them, you may need to boot fo an external thumb (or spinning) drive with a valid operating system. If you do that and find the offending folder, you will be able to delete the entire tree branch. Otherwise attempting to delete will evoke warnings about needed for MacOS.

So you may need to build a thumb or spinning external with Mojave or Catalina OS. The Recovery or Safe Boot (you will not see the folder of booting holding the SHIFT key) do not suffice.

As identified in the Catalina update to 10.15.4 - there is a warning that the Silicon Labs group of extensions and apps has at least one component that will not be supported in the next MacOS.

Looks like Si Labs will have something to fix.

SiLabs continues to make a lot of changes to their drivers. I just uploaded their latest driver to our Mac install page, though I doubt it will fix this particular issue. I'm sure SiLabs will fix this soon...

I’ve just received my Power pod v3 lite and have started reading how to install ISAAC for Mac but maybe I am missing something as your instructions say down load the 6 files and only open and read the instruction file to start with …. well there is my problem there are only 5 links and non are called instructions !

Yikes! There were some old posts out there...I think they are all fixed now. You should now find 6 links on the Mac install page.

Thanks got them all and appear to have all gone as expected through every stage of the install but when I finally connect my powerPod to Isaac I don't get the connection and no green box around the usb symbol ?

It sounds like the SiLabs driver did not load properly.

Go to Apple/Systems Preferences/Security&Privacy/General

I suspect you'll see a message saying "System Extension Blocked" for SiLabs. Click on the "Lock" button, enter your PW, then click on Allow.

Hopefully this will fix the problem.

I am trying to install ISAAC 5.1 on a MacBook Pro running macOS Catalina, version 10.15.4 using these instructions and files.
So far it does not work.

The SiLab driver installer generates this error:
unexpected reply from installKextFromBundle kOSKextReturnAuthentication (-603946995) at /Users/host/jenkins2/workspace/Host_Software_MacOS_Build_VCP_Driver_5.x_Pipeline/driver/silabser/osx/installer2/Install CP210x VCP Driver/Install CP210x VCP Driver/AppDelegate.m:1122

Any suggestions?

Also, connecting my aeropod results in the green light flashing for a bit, then goes to red light flashing.

I am attempting to get this to work on a touchbar MacBookPro running macOS Catalina 10.15.4 (soon to be 10.15.5)
If the NI-488 driver is successfully installed, should the troubleshooting wizard in /Applications/National Instruments/NI-488.2 "work",
or will it say "the NI-488.2 software is not correctly installed on your system" regardless?

I don't use the wizards in the drivers software.

What's important is to precisely follow the install instructions, taking special care to click "Allow" when you see the System Extension Blocked message appear.

I've done that.
Ive gone through the prescribed sequence doing my best to follow the directions numerous times.
By and large I do not find "system extension blocked" messages or "allow" buttons in the security & privacy control panel.
I believe I have only seen that once.

Have you done a clean install on macOS Catalina 10.15.4, as opposed to say 10.15.3 or 10.15.2?

I am responding to your emails so I won't repeat comments here.

Morning,

Has anyone managed to install Issac on a M1 Mac machine?

Thanks,

Since M1 is ARM based this is impossible until an Isaac version is made for ARM.

Unfortunately, the "Rosetta" translator made by Apple to convert Intel programs (such as Isaac drivers made by National Instruments) to M1 does not work properly. This is an Apple defect, not ours; Apple brags about the fact that Intel programs will run on an M1, but not all do.

We have no idea when, or if, National Instruments will make their drivers compatible with the M1 chip.

At this point the best hope is for a virtual machine emulator, such as Parallels or VMWare, to get working on the M1 chip. Both firms are working on this now actively. When this happens Isaac will be able to work.
