Hi Ray,

This CNET article explains...

• https://www.cnet.com/news/6-macos-catalina-security-changes-from-apple-coming-this-fall/
• Protections for low-level system software
• For low-level software some developers write -- the "drivers" used to let a device handle specific hardware like webcams or printers -- Apple is steering developers toward a safer approach.
• In MacOS, developers could write extensions that interface directly with the lowest-level part of the operating system, called the kernel. Now it's begun gradually banishing kernel extensions in favor of system extensions, which are walled off from the kernel so they don't get low-level privileges.
• Catalina will be the last MacOS version that'll run kernel extensions "without compromises," Apple said. And in an unspecified future MacOS version, Apple will prohibit any kernel extensions whose jobs can be done with a system extension.

So the next OS release after Catalina will require System Extentions and Kernel Extensions will no longer be fully supported. The article is unclear, apparently after Catilina kernel extensions will be able to run, but with 'Compromises'.

The development team is aware of this.

The GO64 app I am using to prep for Catalina says that the Promise Utility is already 64 bit except for cli_exeMod.

BundleID: com.promise.PromiseUtility          Version: 4.02.0000.21

I just saw that there is an upgrade for SANLINK 3  N1   (not T1)  (on the 2/12/19)

Apparently the T1 is now a legacy device !!!!!!!!!!

Why this non-old thnuderbolt 3 is already legacy ????

Does N1 drivers work with T1 ??????  what is the solution ?????

Thanks

We went with the solution of upgrading to the N1. It supports more Ethernet modes and uses the same iMac Pro/iMac Mini 10gbe chipset, so same drivers built into Catalina, allowing for easy portability across Macs.

 The T1 was made when Apple had no 10gbe solution at all. If you're a Pro using Apple products... Be prepared to upgrade hardware frequently and not be able to update your OS. This is the Apple way, always has been... If you don't like it, try Linux or ChromeOS. I've also heard about a new thing called WindOS? might work for you.

Sorry for speaking the truth ;)

Sell it on eBay, you'll get good money for it, they are still useful to lots of people and will be for at least 4 years. I'm using the T1 on an old MacBook Air which I turned into a testing server.
