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.
Mac OS Catalina
I’ve updated my system to the latest Mac OS 10.15.1 codenamed Catalina. Well, it broke a couple of apps that I use regularly, Audacity and OBS. There are currently no updates from Audacity. However, OBS has a workaround in terms of a test build. You have to download it, and set the system preferences to allow the Mac OS to access the cameras (webcam) and audio devices (microphones). There are no official releases yet from neither Audacity and OBS projects. Maybe in a couple of months.
