what if macos catalina fucks you?

anaconda, catalina, mac os, python, tools

fuck mac os catalina

not working list

some fixed issues

karabiner

mac os switchResX

for most people

  1. remove previous SwitchResX, make sure you have purged all relevant files. Something like AppCleaner will do the trick.
  2. reinstall latest version(4.9.1 for me)
  3. read the instruction on SwitchResX and System Integrity Protection (SIP)
  4. for a 2k monitor, you need to create a custom relution to use HiDPI diplay mode. So you need to disable the SIP. See zhihu for detailed configuration steps.
  5. After you disable the SIP, you could create a new custome setting and it will remind you to reboot, rather than not installed.
  6. reboot and switch the resolution.

for !lucky guys

If the above instructions are not suitble for me. Please refer to Fixing switchResx saving issue. I do not know the inner reason but I guess it is because you haven’t purged all relevant files in step 1.

BTW, DO NOT forget to enable your SIP again!

anaconda3

it is really annoying when you are a python addict and find your anaconda is broken! 😠

  1. official doc suggests the way to reinstall the anaconda throught command-line fashion.
  2. source ~/anaconda3/bin/activate and conda init zsh and reopen a new shell window
  3. directly move previous envs will not do the trick, since some path is hard-coded.
  4. Unluckily, we should recreate our envs. Again, fuck catalina.
