Warning for others (I found out the hard way): there is a reason why this is still beta software. It may work for some folks, but not everyone. It may prevent your Mac from booting, and you will have to get your hands dirty to fix things.

Thanks for the update @Kevin_Z. Unfortunately, when I installed this on my iMac (2014 5K Retina iMac, Big Sur 11.2.3), the boot froze (I gave it more than five minutes from the point that the boot froze). I rebooted multiple times. I had authorised the kext in System Preferences. Ultimately, I had to delete the kext  from multiple locations using a terminal in Recovery mode in order to be able to boot my Mac successfully.

Hi @Kevin_Z, "kext" refers to "kernel extension". The printer utility installs these and they are loaded as part of boot-up before anyone logs in. They have the file extension ".kext". Disabling loading applications when logging in happens too late to affect the loading of kernel extensions (the Mac hangs before getting to the point in the boot process where this would take place).

The printer controller utility can be loaded (manually or automatically) with the kernel extensions deleted. It just cannot do anything.

@anderscheow Hardware Version: V1 Firmware Version: 0.9.1 5.0 v0032.0 Build 170207 Rel.49213n Hi, I migrated to MacOs Big Sur but the tp link utility doesn't seem to work When I try to install It sends me the message to Allow the application on System Preferences --> Privacy but the app doesn't appear. So I don't know how to go further in the installation process.

Thank you

@Kevin_Z

I just bought Mac Big Sur version 11.3. which contains Apple M1 Chip. After having tried to install, I realize that the latest printer controller utility doesn't support this type. Could you provide us an updated printer controller utility?

@Kevin_Z 

Update: After updating macOS from Big Sur 11.5 to 11.5.2, the app has been functioning as expected without the errors mentioned below.  

After installing the beta for Big Sur, I am prompted to restart the computer.  Before restarting, I am able to print to my TP-Link connected printer. 

However, after restarting I am unable to print and I am prompted by the TP-Link app that the installation is incomplete and to install again.  After installing I am prompted to restart the computer, but before restarting, I am able to print to my TP-Link connected printer again. 

Yet, after restarting, I am prompted again by the TP-Link app that the installation is incomplete and to install again.  This continues over and over.

I have also attempted to install after disabling SIP in recovery but that does not work.

In addition, KCodes is using kextcache while installing which is now deprecated.

It looks like you're trying to update the system caches. As of macOS 11, the personality cache is no longer in use for keeping kext matching information up-to-date. For more information, see `man kmutil`.

Kindly forward to KCodes for a resolution as this is not good for TP-Link.
