Guides
Mac cleanup, by hand
Each guide shows the manual way first, using macOS and the official tools, with a warning wherever data can be lost. Tidlark is mentioned at the end, briefly.
Free up disk space on a Mac
Storage settings, the Trash, Downloads, large files, what “System Data” is, iCloud optimisation, developer caches and Time Machine local snapshots.
For: anyone whose Mac says the disk is almost full, who wants the safe built-in steps before installing anything.
Uninstall apps completely
What dragging an app to the Trash leaves behind in your Library folder, how to find those files by bundle ID, and which folders are shared.
For: people removing an app for good, or chasing a background job or gigabytes of data an old app left behind.
Delete Xcode DerivedData and other Xcode files
DerivedData, Archives, device support files and simulators: what each is, what deleting it costs, and the commands to use.
For: iOS and Mac developers whose Library/Developer folder has grown to tens of gigabytes, and who need to know which parts can’t be regenerated.
Remove Ollama, LM Studio and Hugging Face models
Where local AI models are stored on a Mac, and how to remove them with ollama rm, LM Studio and hf cache rm.
For: anyone who has tried local models with Ollama, LM Studio, MLX or Python libraries and now has 4 to 40 GB files they can’t find.
