- NOTE: Author says running TurboMac in combination with BD_PROCHOT (which CPUTune can do) could cause permanent damage!
- Model: A1466
- Graphics: Intel HD Graphics 4000 1536 MB
- Memory: 4 GB 1600 MHz DDR3
- Processor: i5 1.8 GHz (model 1536M, no T2), but the script may inform you (using
pmset -g therm) of the following issues:- CPU_Speed_Limit = 48 (100 is 100%)
- CPU_Available_CPUs = 4 (4 is expected)
- CPU_Speed_Limit = 31 (100 is 100%)
- You may have to compile CPUTune or other utilities using a different computer with the same version of macOS if the affected computer is too slow:
- I installed Xcode command line tools
- but apparently CPUTune requires Xcode GUI: syscl/CPUTune#43
- apple.com said Xcode 14.5 was for my Catalina 10.15.7
- downloading and extracting it took literally days, even on a wired connection
- There was an 🚫 over the Xcode app
- I tried dragging Xcode to Applications
- Trying to open it resulted in some error about it being corrupt
- When the app is in Applications,
git clonefails and says "xcrun: error: invalid active developer path (/Applications/Xcode.app/Contents/Developer), missing xcrun at: /Applications/Xcode.app/Contents/Developer/usr/bin/xcrun"- git works after removing the app from Applications.
- I installed Xcode command line tools
