XCode after Catalina Upgrade
I tried running git after the Mac OS Catalina upgrade and got this error.
xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun |
Here’s the fix. For some very odd reason, Apple does not automatically reinstall xcode after each Mac OS upgrade.
You will need to either reset it or install it again.
# Try reset first xcode-select --reset # Or install it if reset doesn't work xcode-select --install |
Close your terminal, and reopen and run git again.
Audacity on Catalina
If you’ve recently upgraded your Mac to Catalina or Mac OS 10.15.1, you may have noticed that Audacity is no longer working. To get it working, you’ll need to download version Audacity 2.3.3. However, installing and running it normally the way you’ve done it in the past will not be enough. Because of Catalina, Audacity is not able to gain permissions to the microphone inputs. The only way I was able to get it working is to launch Audacity from the Terminal.
Launch Audacity from the Terminal.
# cd to Application directory cd /Applications/Audacity.app/Contents/MacOS # Run it in the background bash Audacity.sh & |
Click Ok if prompted to use the microphone.
