I have this functioning in Sierra 10.12.5. I don't assume responsibility if you follow these instructions but they are provided in good faith.

Inspired by this post: http://www.insanelymac.com/forum/files/file/522-mediatek-mt7610u-mt7612u-kext-and-network-utility-sierra-working/

Steps:

1. Download http://static.tp-link.com/Archer T1U(US)_V1_161223_Mac.zip

2. The zipfile does not extract for me easily using command-line unzip or the Finder built-in so do this in Terminal.app: unzip Archer\ T1U\(US\)_V1_161223_Mac.zip Archer_T1U\(US\)_V1_161223/TP-LINK_Installer.dmg

3. Double-click TP-LINK_Installer.dmg in Finder

4. Copy Installer.pkg to somewhere on your HDD

5. In Terminal.app:
$ pkgutil --expand Installer.pkg InstallerContents
$ cd InstallerContents/
$ ls
Distribution Resources rt2870resources.pkg
$ cd rt2870resources.pkg/
$ ls
Bom PackageInfo Payload Scripts
$ file Payload

$ mv Payload Payload.gz
$ gunzip Payload.gz
$ file Payload
Payload: ASCII cpio archive (pre-SVR4 or odc)
$ cpio -i < Payload

Follow these instructions to install that specific kext: http://osxdaily.com/2012/01/12/how-to-manually-install-kernel-extensions-in-mac-os-x/

Once restarted, remount the TP-LINK_Installer.dmg and run the Installer.pkg inside it like you normally would. Restart again. When you log in with this user, the Wireless Utility should start up and you can select your Wireless SSID and connect. Done!

I have found for other users you need to set up the Wireless Utility that was installed in /Applications/TP-LINK Wireless Utility as a login item under System Settings > Users & Groups > (User) > Login Items.

Hope that helps!

"ElCapitan" folder is misspelled into folder "Driver". What is supposed to be "l" (ell) is a capital "i" after the capital "E" in "ElCapitan", I know how to rename the file, but I don't know how to rebuild the Install.pkg with this fix.

On the other side,... I followed the instructions but no success on High Sierra.

ElCapitan folder is misspelled inside Installer.pkg. What is supposed to be an "l" (lowercase ell) is a capital "i". Maybe a bug that makes installer doesn't work. I don't know how to rebuild the installer once the folder is renamed to its correct name.

On the other side, I've tried deathanddrek step-by-step procedure but the dongle didn't work on my MacBook Pro (HighSierra)

I have checked that NO driver for MAC os 10.12 on tp-llink official website, only up to OS10.11 for this adapter now
