@@ -13,63 +13,74 @@ An example of using `sudo`, when your controller is ATMega32u4:
 
 or just:
 
-    $ sudo make <keyboard>:<keymap>:dfu
+    $ sudo make <keyboard>:<keymap>:flash
 
 Note that running `make` with `sudo` is generally ***not*** a good idea, and you should use one of the former methods, if possible.

-## `avr-gcc: internal compiler error: Abort trap: 6 (program cc1)` on MacOS
-
-This is an issue with updating on brew, causing symlinks that avr-gcc depend on getting mangled.
-
-The solution is to remove and reinstall all affected modules.
-
-```
-brew rm avr-gcc avr-gcc@8 dfu-programmer dfu-util gcc-arm-none-eabi arm-gcc-bin@8 avrdude qmk
-brew install qmk/qmk/qmk
-brew link --force avr-gcc@8
-brew link --force arm-gcc-bin@8
-```
-
-### `avr-gcc` and LUFA
-
-If you updated your `avr-gcc` and you see errors involving LUFA, for example:
-
-`lib/lufa/LUFA/Drivers/USB/Class/Device/AudioClassDevice.h:380:5: error: 'const' attribute on function returning 'void'`
-
-For now, you need to rollback `avr-gcc` to 8 in Homebrew.
-
-```
-brew uninstall --force avr-gcc
-brew install avr-gcc@8
-brew link --force avr-gcc@8

 ### I just flashed my keyboard and it does nothing/keypresses don't register - it's also ARM (rev6 planck, clueboard 60, hs60v2, etc...) (Feb 2019)
 Due to how EEPROM works on ARM based chips, saved settings may no longer be valid.  This affects the default layers, and *may*, under certain circumstances we are still figuring out, make the keyboard unusable.  Resetting the EEPROM will correct this.
